Análise genética na investigação de origem da tilápia (Oreochromis niloticus) em cultivos comerciais
(2019-07-12) Silva, Gênison Carneiro; Coimbra, Maria Raquel Moura; http://lattes.cnpq.br/7669497233462075; http://lattes.cnpq.br/3679959470967021
The development of genetically improved tilapia strains was an important step in world aquaculture, considering growth, reproduction, weight gain, fillet yield and greater rusticity of the selected individuals. Acquiring improved seeds is the first step to shortening production time, however, the fish farmer should provide adequate conditions and structure to achieve optimal maximum performance. In biphasic tilapiculture systems in excavated nurseries, it is common for the nursery phase to occur in a different location than the fattening phase. In this case study, one producer purchased improved fingerlings from a tilapia breeding company “A” and sent them to company “B” to conduct the nursery phase. However, when such the producer received the “B” tilapia juveniles and fattened them, they did not show the expected zootechnical performance. The objective of this study was to detect if the tilapia of "A" and "B" had the same genetic origin. Were used genetic markers such as microsatellites and mitochondrial DNA control region (D-loop). A total of 79 samples were collected, of which 40 were from “A” and 39 from “B”. The samples had their total DNA extracted and were genotyped for the UNH104, UNH106, UNH160 and UNH208 microsatellite markers. Then, the samples had the control region haplotypes identified by sequencing. The genetic diversity of microsatellites was analyzed to correctly attribute that the origin of "B" came from "A". The alignment and editing of the D-loop also revealed a haplotype network with equitable stakes of "A" and "B" confirming that the groups belonged to the GIFT lineage. The techniques used show that the different zootechnical performance should be associated with issues related to the adopted management and stocking density during the nursery phase.
Análise investigatória do método de reversão sexual da tilápia do nilo (Oreochromis niloticus), linhagem Chitralada, na piscicultura Mar Doce do Nordeste
(2019-07-19) Silva, Joab Joaquim da; Ponzi Junior, Manlio; http://lattes.cnpq.br/1423075666160782; http://lattes.cnpq.br/6664018329829121
This work was developed inside the facilities of Mar Doce do Nordeste Piscicultura e Projetos Ltda., attempting to confirm if the sexual reversion process of the Nile Tilapia (Oreochromis niloticus) fingerlings was inside what was foreseen in Pompa & Green’s reversion technique, using the masculinizing hormone 17 α-methyltestosterone, obtaining then, as detailed by the technique, monosex specimens with reversion rate above 95%. The fishes were fed with feed containing 60 mg/kg of 17 α-methyltestosterone, which was given 6 times per day, during the period of 28 days in a masonry vivarium in the first 10 days, followed by 18 days in another vivarium dug in the ground. After 120 days of cultivation, the specimen were slaughtered and eviscerated to posterior visual analysis of the gonads. The obtained results revealed reversion rates lower than what were expected with the correct application of Popma & Green’s reversion technique, appointing the protocol’s necessity of revision, in order to reach monosex specimen and improve the quality of the commercialized tilapia’s fingerlings.
Aquicultura multitrófica: crescimento das macroalgas Kappaphycus alvarezii e Hypnea musciformis no cultivo do camarão marinho Litopenaeus vannamei
(2021-12-21) Oliveira, Artur Ludermir de; Dantas, Danielli Matias de Macêdo; http://lattes.cnpq.br/3422902414863662; http://lattes.cnpq.br/1810381478994494
The obligatory supervised internship (ESO) aims to prepare students to work in the job market, allowing them to apply theoretical concepts acquired during under graduation course in practice. OSI also allows student to experience and learn about the difficulties faced in aquaculture production units. This report refers to the realization of the ESO at the Santa Helena farm, belonging to Camares-Camarões Marinhos Ltda, located in the coastal zone of the state of Rio Grande do Norte, more specifically in the city of Caiçara do Norte, during the period from October to December of 2021. During the internship, activities related to the cultivation and management of marine macroalgae were carried out, in an experimental manner, in order to measure macroalgae growth and carry out macroalgae management in the marine shrimp ponds. The project developed during the internship had as main objective to measure the growth of Kappaphycus alvarezii and Hypnea musciformis in three different cultivation structures (Tubular Net, Rope and Pillow) around the property's facilities in a 4 weeks period. The parameters of Total Biomass Gain in gram (GTB), Total Growth (CT) and Daily and Weekly Relative Growth Rate (TCR) were evaluated. During the internship period, it was also possible to assist and monitor the most diverse activities that take place in a marine shrimp farm, such as: application of bokashi, liming the nurseries, receiving post larvae, maintenance of the supply channel, population of the nursery, as well as other routine activities. The best results for the species K. alvarezii were: 2850g of GTB, 475% of CT, 6.25% of daily TCR and 43.73% of weekly TCR, grown in rope structure in the catchment pond. For the species H. musciformis, the results of 1600g of GTB, 266.67% of TC, 4.64% of daily TCR and 32.48% of weekly TCR cultivated in a pillow structure in the catchment pond. In this way, it was possible to confirm how important a sustainable management applied in a shrimp farm is, because with the bioremediation of algae, in addition to reducing the environmental impacts on agroecosystems, it was also possible to maintain a good productivity of shrimp in the nurseries. Due to the growth found of the macroalgae in question, it is also worth considering the possibility that, in the future, the cultivation of some of these algae species will have promising results in the Northeast region, thus enabling the emergence of an economically promising activity.
Aquicultura vai à escola parte II – uma extensão prática da aquicultura em Itapissuma-PE
(2021-02-05) Santos Filho, Fernando Sebastião dos; Olivera Gálvez, Alfredo; Santos, Elizabeth Pereira dos; http://lattes.cnpq.br/5362345525199085; http://lattes.cnpq.br/7002327312102794; http://lattes.cnpq.br/1445666896933448
Due to the stagnation of fishing activity in recent years, aquaculture has emerged as an alternative to supply the demand for fish worldwide; with this, this type of production of food and biotechnological products has been growing significantly to meet the needs of the entire world population. According to FAO, aquaculture is the culture under control of aquatic animals and plants. Among the branches of aquaculture, we have: Pisciculture (Fish cultivation), Malacoculture (Mollusk cultivation), Shrimp farming (Crustacean cultivation) and Algiculture (Algae cultivation). In this study, the extension worker, together with undergraduate and graduate students linked to the Department of Fisheries and Aquaculture at the Federal Rural University of Pernambuco, went to the high school reference school (EREM) Eurídice Cadaval in Itapissuma - PE in order to establish an exchange of learning with regard to aquaculture, publicizing the activities linked to the baccalaureate course in fisheries engineering, which is currently not widespread in society, in addition to the performance of this professional in the area related to the productive sectors of the Itapissuma region (fish, crustaceans , mollusks and algae). The work was carried out through dynamic, practical and theoretical classes, given to high school students. In these classes, social, cultural and environmental topics were approached from the highlight of the problems that surround the daily life of the community, thus helping in the development of these students as citizens, opinion makers and future professionals who can work with the community they live.
Aspectos da biologia populacional de Nematopalaemon Schmitti (Holthuis, 1950) e Exhippolysmata Oplophoroides (Holthuis, 1948) no litoral sul de Pernambuco
(2018) Santos, Luan Danylo Noronha dos; Oliveira, Vanildo Souza de; Eduardo, Leandro Nolé; http://lattes.cnpq.br/3271149306128845; http://lattes.cnpq.br/4724844442437274; http://lattes.cnpq.br/1576026557122700
Exhippolysmata oplophoroides and Nematopalaemon schmitti are two species of caridea prawns caught as bycatch by shrimp trawls. Along the Brazilian coast, the biological and ecological information of these two species are still scarce, especially on the northeastern coast. This works aims to collect biological and ecological information about these species in the coast of Pernambuco to understand its importance for the marine ecosystem and fishing. The collections were carried out monthly between September/2017 and August/2018, in Sirinhaém/PE, in a shrimp artisanal boat. During the study period, the number of individuals and the reproductive status (ovigerous and non-ovigerous) were counted to access reproductive peaks. The proportions of Caridae prawns Penaeus schmitti, Penaeus subtilis and Penaeus kroyeri prawns were also compared. For E. oplophoroides, the months of greatest abundance were October and May with the highest peaks of females ovated in February, March and May; and N. schmitti with greater abundance in July and August, and higher peak of individuals ovated in December and July. However, seabob shrimps presented the highest percentage of all shrimp measured (85.6%). The results of this work were important to generate the first ecological and biological information on the species in the state of Pernambuco and on the northeastern coast, contributing with the understanding of its importance to the ecosystem and possibly with a sustainable management plan for the fishing activity.

Avaliação da digestibilidade de farinha de cefalotórax de camarão (Penaeus vannamei) em dietas para tilápia (Oreochromis niloticus)
(2023-09-22) Campelo, Kesya Leal; Santos, Juliana Ferreira dos; http://lattes.cnpq.br/6621907859216486; http://lattes.cnpq.br/2587814165212462
In order to promote knowledge about alternative ingredients for aquatic animal feed formulations, the apparent digestibility coefficients (ADC) of protein, dry matter and crude energy of two ingredients in tilapia feed were determined. Seventy-two juvenile Nile tilapia (Oreochromis niloticus) with an average weight of 61.85±10.06 g were used in a completely randomized experimental design with three treatments, three replications and eight fish per box, alternating between the box and the hatchery. Three treatments were used: Reference feed, based on the nutritional needs of the species; Test feed consisting of the reference feed with the addition of shrimp cephalothorax meal (P. vannamei) whole with reference feed; Test feed consisting of the reference feed with the addition of shrimp cephalothorax meal (P. vannamei) with low fat content. The ADC was determined by the indirect method using 1% celite as an inert indicator. The CDA for crude protein was 94.14% and 94.22% and digestible values for crude protein were 51.96% and 56.90%; for dry matter, 92% and 91.8%; for energy, 92%; and digestible values of 80 and 89% were found. Shrimp cephalothorax waste was considered a potential substitute for protein in feed for the species.

The aim of this study was to evaluate the stocks situation of the most penaeidae species catched and propose management measures for Northeast region stocks. For this, available data about catch and growth were analyzed for these species. First of all, the overall catch was analyzed over the years and state of the fisheries assessed using data poor models. The results showed that Northeast shrimp fishing growing over the years and about caught species, pink shrimp (Penaeus Subtilis) have a first catch length around Lc = 9 cm, giving yield per recruit of Y/R = 1,08 g, fishing mortality Fmsy = 4,9, with catches below first maturation length (L50), giving a Maximum Sustainable Yield around 532 t. For sea-bob shrimp (Xiphopenaeus Kroery) which is more abundant than others, was observed with Lc = 8 cm, a Y/R= 0,16 g, Fmsy=12, being catched above first maturation length (L50), showing Maximum Sustainable Yield around 7525 t. For white shrimp (Penaeus Schimitt) Lc = 10 cm, Y/R = 1,30 g, Fmsy = 6,2, with catches below the L50 and an estimated Maximum Sustainable Yield around 3300 t. In general, these fisheries are carried out without catch quotas, below first maturation length (L50) and high fishing mortality coefficients, but according to F and Lc combinations there have been no signs of declining yields or overfishing. Knowledge about maximum sustainable yield and yield per recruit can be useful for management decisions about these resources.
Avaliação de dispositivos de exclusão com painel de malha quadrada em redes de arrasto para camarão, na frota de Sirinhaém - PE

The capture of shrimp trawls has generated significant volumes of accompanying fauna and consequently environmental damage. Currently, one alternative that minimizes this impact is the use of exclusion devices. This work evaluated the efficiency of the square mesh device in different locations in the net. The trawls were carried out in Barra de Sirinhaém, Pernambuco. The experiments consisted of one-hour trawls and divided into two phases, comparing the fisherman's netfishing "RP" with a similar netfishing containing a square mesh panel in the body "MQC". The second phase compared the "RP" with the net containing a square mesh panel in the "MQS" bag. The "MQC" caught a larger volume of shrimp and fish, with no significant differences in weight for white shrimp (ρ = 0.808), red shrimp (ρ = 0.814), sea-bob shrimp (ρ = 0.675) and fish (ρ = 0.849) and "MQS" significantly decreased fish catch by weight (Ρ = 0.00942) and number (ρ = 0.000571) without affecting the production by weight of white shrimp (ρ = 0.159), red shrimp (ρ=0,981), sea-bob shrimp (ρ = 0.619). Regarding the most frequent length classes, "MQC" and "MQS" captured larger specimens of red shrimp and fish, compared to their "RP". The modifications in the nets allowed the escape of smaller individuals, and the use of the device in both places, did not affect significantly their shrimp production. The device with square meshes in the bag was the most efficient, presenting significant differences in fish exclusion, both in number and weight, thus being the most promising to be implemented.

Avaliação de plano de negócio em piscicultura de tanques-rede: uma abordagem estratégica
(2023-09-15) Santos, Filipe Luiz Perman dos; Ponzi Junior, Manlio; http://lattes.cnpq.br/1423075666160782; http://lattes.cnpq.br/0502000941144606
The activity of fish farming in cage systems has become a widely recognized practice within the scope of Brazilian aquaculture, standing out mainly for its low production cost and simplicity compared to other methods. Specifically in the Northeast, fish farming activities in this modality are mainly concentrated in riverbeds and notably in vast water reservoirs, such as the dammed areas of the São Francisco River. However, it's relevant to note that many small-scale farmers who transitioned to fish farming maintain commercial behaviors similar to their original practices. These producers, for the most part, operate informally, are unorganized, and often lack basic knowledge about business structure, whether individual or collective. Consequently, they primarily function as raw material suppliers for middlemen or large corporations, often without a clear understanding of the actual cost of their production. This study suggests that, through targeted assistance, even the most traditional producers can have access to business indicators. It is recommended that under effective leadership or through the professional management of a cooperative, such producers can position themselves more competitively in the market. The idea is that they shouldn't limit themselves to fish production, but also develop products with added value and have insight into the best distribution strategies for consumers. This research emphasizes the importance of managerial and strategic considerations, materialized through comprehensive indicators and analyses, which have the potential to elevate such ventures to higher levels. Furthermore, the training and organization of these small producers can generate significant socioeconomic impacts in a locality. Enhancing the added value in their products boosts income generation, promotes community empowerment, and stimulates local development. Economic growth, combined with proper training, can result in improvements in quality of life, education, and infrastructure, positively transforming the socioeconomic landscape of the region.

This is a quantitative research that sought to identify the consumption of fish by the buyers within the public market of the Boa Viagem neighborhood, Recife / PE, as well as the commercialization and conservation of fish in the local market. To reach this objective, a questionnaire was applied to 80 consumers, aiming to identify the sex (female / male), the age of the participants, if they consume fish and what the quantity in kg per purchase and the weekly consumption, besides the identification of the preference for the type of fish, the opinion on the hygienic conditions of this commercialization. This instrument was applied in February 2018, in the Public Market of Boa Viagem. It was possible to infer that the majority of fish consumers do so in an amount inferior to that established by the World Health Organization (WHO). We also identified that meat consumption is higher among subjects over 40 years of age, and that preference is higher for fresh and eviscerated fish. In addition, it was identified that of the responses analyzed, the purchase preference is for fish (60% of the total) when compared to crustaceans and molluscs. Regarding the hygienic-sanitary conditions, it was identified that they are inadequate with respect to the final product presented for purchase, corresponding to a percentage of 72% of the total participants.
Avaliação do crescimento e rendimento em biomassa das diatomáceas Amphora sp., Chaetoceros calcitrans e Thalassiosira fluviatilis
(2020-10-29) Lima, Jasiel José de; Olivera Gálvez, Alfredo; Moraes, Laenne Barbara Silva de; http://lattes.cnpq.br/1483699193923171; http://lattes.cnpq.br/7002327312102794; http://lattes.cnpq.br/0975356390769917
Microalgae are autotrophic microscopic organisms that form a heterogeneous group, predominant in aquatic environments, responsible for most of the oxygen and primary production of the Earth. They are classified into four main groups: Cyanophyceae, Chrysophyceae, Chlorophyceae and Bacillariophyceae (diatoms). These microorganisms produce various organic compounds and are commonly used in several branches of industry and aquaculture. The present study aimed to evaluate the growth and yield in dry biomass of the diatoms: Amphora sp., Chaetoceros calcitrans and Thalassiosira fluviatilis. The experimental design was completely randomized, with three replications for each species, totalling nine experimental units. For growth evaluation, daily counts were performed in a Neubauer chamber and optical microscope, obtaining the variables: growth rate (K), doubling time (DT) and maximum cell density (MCD). Likewise, growth curves were drawn up adjusted by approximating the logistic curve. At the end of the cultivation, the dry biomass yield was obtained, after the centrifugation steps, to remove the supernatant and lyophilization, to dry the biomass. As a result, higher DCM and K were obtained for C. calcitrans (1,225 x 104 cells mL-1 and 1.58 div day-1) and higher dry biomass yields for T. fluviatilis (0.61 g L-1) and Amphora sp. (0.46 g L-1). The three species showed different parameters of growth and yield in biomass, being T. fluviatilis and Amphora sp. favorable for yield in dry biomass and C. calcitrans to reach higher cell densities.

In view of the high demand for brine shrimp larvae in marine shrimp larviculture, due to nutritional richness and practicality in management, several studies have focused efforts on techniques to preserve their biomass, since microcrustaceans are highly subject to decomposition. This study aimed to evaluate the use of canned Artemia salina nauplii in the larval cultivation of Litopenaeus vannamei. An experiment was carried out then a validation in commercial larviculture, Maris Laboratório - CE, both lasting 5 days. The first in 10 L buckets with 2 treatments (AN = fresh brine and AC = preserved brine) and 4 replicates. The validation in 25 m³ tanks, with the same treatments, but without repetitions. The larvae were accompanied by misis 1 to PL2 and evaluated by means of the following analyzes: bacteriological being performed at the beginning, middle and end of the experiment; water quality every day with the parameters of temperature, salinity, pH, ammonia and nitrite; finally, the zootechnical performance through the evaluation of larval quality, larval development index, survival, length and TBI. The data were submitted to ANOVA by the Tukey test for normally distributed data, the differences were reported when (P <0.05). The results were within the recommended standards for the species and there were no significant differences in the evaluations between treatments in any of the experiments. For future work, it is recommended to evaluate the economic viability of the product. Thus, it is possible to replace the nauplii of A. salina in natura by the one conserved in the larval cultivation of L. vannamei, since the test treatment did not alter the evaluated indexes.
Avaliação físico-química e microbiológica do camarão cinza (Litopenaeus vannamei) submetido à defumação líquida em diferentes temperaturas e tempos de processamento
(2021-12-10) Silva, Chirley Matilde da; Oliveira Filho, Paulo Roberto Campagnoli de; http://lattes.cnpq.br/8043850276929205; http://lattes.cnpq.br/7594584352507927
The gray shrimp (Litopeaneus vannamei) is one of the most cultivated fish species in the world due to its good performance in captivity, great market acceptance and its meat rich in protein. However, it presents a reduced shelf life due to the high water activity and a pH close to neutrality. One way to preserve shrimp and increase its shelf life is the use of liquid smoking, which is cleaner and healthier than traditional smoking. The objective of the study was to evaluate physicochemical and microbiological aspects of shrimp subjected to the liquid smoking process by testing different times and temperature. Before smoking, liquid smoke (20% dilution) was sprayed on the cleaned and salted shrimp. The shrimp were smoked in an oven with the following treatments: A - 80°C/5h, B - 85°C/4h, C - 90°C/3h. Analyses of yield, shrinkage percentage, color, texture, water holding capacity (WCR), water activity, moisture percentage and microbiological analyses were performed. The liquid smoking of shrimp at 80°C for 5 hours (Treatment A) caused lower yield, higher percentage of shrinkage, higher water holding capacity, higher hardness and lower percentage of moisture and water activity. In the shrimp submitted to smoking at 90°C for 3 hours (Treatment C) there was a higher yield, lower percentage of shrinkage, lower water holding capacity, lower hardness and higher percentage of moisture and water activity. The color of the shrimp showed no difference (P<0.05) among the proposed treatments. In the microbiological analysis, the results were within the standard required by Brazilian legislation. This shows that the variation of two hours of smoking time (3 to 5 hours) causes more influence, except for color, on the physicochemical aspects than the variation of 10°C (80 to 90°C) in the temperature of the process. It is concluded that the liquid smoking of shrimp at a combination of 90°C for 3 hours is more suitable because it causes a higher yield, a lower percentage of shrinkage and a softer (lower hardness) and juicier product (higher percentage of moisture), having a great potential for production and commercialization.
