Rio Marié: rio de gigantes
(2017-07) Pires, Éverton Luís; Oliveira, Paulo Guilherme Vasconcelos de; http://lattes.cnpq.br/5700488412022830; http://lattes.cnpq.br/7517851859591874
The idea of working as a fishing guide came from an old feeling and willingness to work professionally with what you really enjoy. Allied to the passion for fishing since childhood and a great desire to know the Amazon, this dream was possible through the realization of this trainee experience supervised by the company Untamed Angling do Brasil, in the waters of Marié River. Marié River is a tributary of the Rio Negro and is located in the border regions with Colombia and Venezuela, northwest of the Brazilian Amazon. It has more than 800 kilometers navigable, with more than 180 known streams, 60 lakes, and three main tributaries, being all this protected area, inserted in an indigenous territory. This project was born through a reference term proposed by the competent authorities that invited fishing tourism companies interested in presenting work proposals to solve the problem of fishing disorganization in the region by companies that disregarded local communities and established precarious contracts. With this term of reference, 14 local communities were benefited, generating a capital of around R $ 170 thousand per year in salaries alone, with more than 1.2 thousand beneficiaries and the various infrastructure improvements made in the communities. Today, the Marié River stands out as the first reserve of sport fishing legally exclusive of the entire Amazon, inserted in an indigenous territory. This advance in favor of Brazilian sport fishing has served as a model for other fishing operations that seek the sustainability of local communities and high quality that will satisfy even the most demanding fishermen. In order to maintain the IBAMA's merit of being the river with the largest tucunarés in the entire Rio Negro, monitoring should be done throughout the season and data analyzed by the competent bodies to evaluate fishing effort, inventory capacity and the continuity of the the fishing operation. The fishing guides who work in the Marié River are passive to a process of mutual learning, where local knowledge is mixed with global knowledge, by living with indigenous guides and tourists from all over the world. All the technical knowledge transmitted to the tourists by the fishing guides must be allied with the empirical knowledge transmitted by the indigenous guides, thus ensuring the success of the catches. During the fishing season, professional fishing guides are responsible for piloting the fishing vessel, assisting the amateur fisherman in catching the fish and returning it to its environment, using the best baits, interpreting the environment specific to the environment Aquatic, as well as other correlated actions in the sport fishing exercise.
Avaliação de dispositivos de exclusão com painel de malha quadrada em redes de arrasto para camarão, na frota de Sirinhaém - PE
(2018) Nascimento, Erika Martha de Lima; Oliveira, Vanildo Souza de; http://lattes.cnpq.br/4724844442437274; http://lattes.cnpq.br/9750351541049029
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.

Cultivo de camarão marinho (litopenaeus vannamei) na Secretaria Executiva de Ressocialização, Ilha de Iitamaracá - PE
(2018) Berto, Sidney Sheldon da Costa; Silva, Luis Otávio Brito da; http://lattes.cnpq.br/3365265235618078; http://lattes.cnpq.br/0014180487418321
This report refers to completion of Stage Observed Required in the Supervisão de produção (SUPROD) of the Secretaria executiva de Ressocialização, in the rural area of the ilha de Itamaracá, which developed between October and December 2018, totaling 300 hours. During this period they were made shrimp farming activities in the production, since the restructuring of nurseries for fish removal of shrimps for marketing. The supervisão de produção aims to re-educate and reintroduce in the common society people who have committed some crime and therefore have been removed from the community. The SUPROD has a total area of 1,254 ha for many different agronomic production activities and zootechnical of this total, 11 hectares are dedicated exclusively to the production of marine shrimp in the shrimp farming industry. Only one nursery of 0.9 ha is in full operation, shrimp farming is the most profitable activity of SUPROD. The water supply is carried out by the Santa Cruz Canal by opening the floodgates in the high tide period. The water supply enters through the gate flooding the nurseries. The cultivation system adopted is the single-phase with direct settlement, using post-larvae (pL10) from the commercial laboratory (Aquatec, RN). The post-larvae are fed commercial feed of Camanutri CR2 with 40% crude protein and granulometry of 0.4 -1.0 mm in a period of twenty five days, after which a 6-day transition period of for the pellet feed with 32% crude protein with 2.4 mm granulometry until the end of the culture. At the end of the cultivation cycle, the animals are harvested and marketed to local merchants in the premises of SUPROD itself. The production of the observed cycle was 602.6 kg, mean final weight of 9.5 g, cultivation time of 74 days, feed conversion factor (FCF) of 1.14, survival of 70.18% and average productivity of 2,462.6 kg / ha / year, considering four cycles per year. Due to budgetary and technical difficulties, the farm still presents a very rudimentary form of cultivation, requiring the adoption of more appropriate measures for cultivation, such as: use of inorganic and organic fertilization in the soil, treatment of soil organic matter in the period between cycles, to improve the method of post-larvae acclimatization, monitoring and treatment of nursery water. These suggestions are intended to help reduce economic losses and increase production.
Potencial de utilização da carne do saramunete (Pseudupeneus maculatus) para elaboração de embutido tipo salsicha
(2018) Silva, Leandro José da; Oliveira Filho, Paulo Roberto Campagnoli de; http://lattes.cnpq.br/8043850276929205
Brazil has an enormous fishing potential due to the immense extension of the coast and the great amount of species that inhabit these waters. Of the total amount of extractive fishery, the majority is made by artisanal fishing. Among the various species captured saramunete (Pseudupeneus maculatus), which is a fish that occupies shallow waters especially on sand and rock bottom in reef areas. Despite being widely captured in the brazilian coast, there are not yet studies evaluating the meat of saramunete for use in sausage type products. Therefore, the goal of the present study was to evaluate the potential of saramunete’s meat for the elaboration of sausages type sausages and to evaluate the nutritional, physical-chemical and microbiological aspects. The formulation of the sausages was composed by fillets of saramunete (80%) and mechanically separated meat obtained from the ridge resulting from filleting (20%). The remaining ingredients were added in the following proportions: 1% corn starch; 2% soy isolated protein; 6% sunflower oil; 6% water; 1.4% salt; 0.2% curing salt; 0.25% antioxidant, 0.25% stabilizer, 0.2% garlic powder, 0.1% black pepper, 0.1% Jamaican pepper; 0.1% onion powder and 0.1% ginger powder. The sausages of saramunete showed 71.53% of humidity, 6.21% of fat, 2.10% of ashes and 19.15% of protein. The color of the inner region presented luminosity (L *) of 65.64, intensity of red (a *) of 6.02 and intensity of yellow (b *) of 13.80. The color of the external region presented luminosity (L *) of 61.98, intensity of red (a *) of 6.00 and intensity of yellow (b *) of 14.48. The water activity value was 0.98, pH 6.78, hardness 1092.44 g, cohesiveness 0.56 and elasticity 8.62 mm. It is observed, therefore, that according to evaluated technological aspects, meat of saramunete (fillets and mechanically separated meat) has the potential to be used in the elaboration of a product of high added value, such as sausage-type sausages, and can be produced both by artisanal fishermen and by the processing industry.
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.

Desempenho da Daphnia magna (Straus, 1820) cultivada em efluente de Tilápia do Nilo cultivada em sistema de bioflocos com diferentes relações C:N
(2019) Bruzaca, David Nunes Aguiar; Olivera Gálvez, Alfredo; http://lattes.cnpq.br/7002327312102794; http://lattes.cnpq.br/8145992758069560
In aquaculture, systems with minimum water exchange are an alternative to sustainable farming. Biofloc technology (BFT), which consists of the formation of microbial aggregates through the manipulation of the carbon: nitrogen ratio of the culture medium is an option in reducing the emission of effluents. However, the accumulation of nitrogen and phosphate residues over several crop cycles in this system ends up causing significant impacts with the release of effluent into the environment. Therefore, Daphnia magna, which is a microcrustacean of the cladoceran family that benefits from the organic mater present in the aquatic environment, can be used for the bioremediation of this effluent. The cultivation of this microcrustacean is traditionally carried out in a clear water system with the addition of the microalgae Chlorella vulgaris in its diet. In this way, the present work aims to evaluate the performance of D. magna cultivated in effluent waters of the BFT system in different carbohydrate: nitrogen ratios with the inoculation of C. vulgaris microalgae and fish feed supplementation. The experimentation is done with six treatments in triaplicates based on two factors, being : Ratio C: N (10: 1, 15: 1 e 20: 1) and Feed (with addition of fish feed (R) or without addition of fish feed (SR)). The variables of water quality: temperature (°C), dissolved oxygen (mg.L-1), salinity (gL-1), pH, NO2 (mg.L-1), TAN (mg.L-1), hardness and alkalinity were measured throughout the culture. The specific growth rate (TCE), doubling time (TD), maximum mean density (DMX), yield (R) and day of maximum density (DMD) were verified for the growth variables. To the variables pH, temperature, Salinity, TAN, Nitrite and Hardness there were no significant differences (p> 0.05) throughout the culture. Regarding dissolved oxygen there was a significant difference for the ration factor and for the interaction between the ration and feed factors. There was also a significant difference when the alkalinity was treated for the ration factor, the feed factor and for the interaction between them, with an average of 50.93 and 80.37. The pH, dissolved oxygen and temperature were favorable for the proper development of the cladoceran. Although there were statistical differences only for the ration factor, the DMXs were between 1001 ± 283 and 3433 ± 267 org.L-1. The days of maximum density were 12º, 14º and 18º days. The 10SR treatment provided a higher average maximum density of Daphnia magna on the 14th day of cultivation, besides showing TCE, TD and R values higher than the other treatments. However, all treatments allowed the growth of the cladoceran, proving that the use of the effluent is an alternative to the production of live food.

(2019-02-05) Ribeiro, Pedro Vinicius de Oliveira; Silva, Suzianny Maria Bezerra Cabral da; Correia, Eudes de Souza; http://lattes.cnpq.br/1573696341397169; http://lattes.cnpq.br/8569566022920336; http://lattes.cnpq.br/7296152139446076
Among the several ways of intensive production in aquaculture that have been highlighted through good results with limited water use and allowing higher densities in culture is the biofloc technology (BFT). This work evaluates the performance of the intensive cultivation of Nile tilapia - Oreochromis niloticus - with bioflocosis technology in the raising phase, with a mean weight of 2.9 ± 0.09 g, using different levels of crude protein (CP) (commercial). The experimental design was completely randomized, involving four levels of protein (28, 32, 36 and 45% of CP), with four replicates each. The work lasted 63 days, and was carried out in boxes of 40L of useful volume, with 10 fish in each box (250 alevinos / m³). We evaluated, Weight Gain, Daily Weight Gain, Specific Growth Rate, Survival, Biomass Gain, Food Conversion Factor and Productivity. Among the water quality variables, the temperature and pH were within the comfort range of the species (27 and 32 ° C, 6 and 8.5) respectively, the dissolved oxygen had averages above 6mg / L. Nitrogen from total ammonia as well as nitrite was within the acceptable level for the cultivation of the species (18.6 mgL -1 and 2.12 N-NO2). The performance variables were not affected by the different levels of dietary protein (P> 0.05). The final weight was about 35g for the treatments and survival was higher than 75% for all treatments, while the productivity ranged from 6.62 to 10.08kg / m³. The study showed that crude protein levels of the feed can be reduced up to the level of 28% of crude protein in the diet in the intensive cultivation of Nile tilapia fingerlings - Oreochromis niloticus - using the biofloc system, without compromising the weight final weight gain, daily weight gain, specific growth rate, food talk factor, survival and productivity.

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.
Produção do camarão-rosa, Penaeus subtilis (Pérez-Farfante – 1967) e P. brasiliensis (Latreille - 1817), camarão-sete-barbas (Xiphopenaeus kroyeri - Heller, 1862) e o camarão-branco (Penaeus schmitti - Burkenroad, 1938) relacionados à pluviometria e sazonalidade na Barra de Sirinhaém, Pernambuco, Brasil
(2019-06-19) Calheiros, Barbara Ferreira Fragoso; Oliveira, Vanildo Souza de; http://lattes.cnpq.br/4724844442437274; http://lattes.cnpq.br/0705353773545871
The greatest expressiveness of shrimp catches on the coast of Pernambuco is concentrated in three main genera: pink shrimp, Penaeus subtilis (Pérez-Farfante – 1967) and P. brasiliensis (Latreille – 1817), seabob shrimp (Xiphopenaeus kroyeri - HELLER, 1862) and white shrimp (Penaeus schmitti - BURKENROAD, 1938) (ANDRADE, 2016). The objective of this monograph is to analyze the production of shrimp trawling and bycatch in terms of seasonality (winter/summer) and rainfall in Barra de Sirinhaém. The collections were carried out monthly from May 2017 to November 2018 on an artisanal double rig shrimp boat. To compare the production of shrimps and bycatch, a monthly ratio between catches was made by means of the average proportion, in kilograms. In order to determine the period of higher productivity of shrimps, the monthly proportion of kilograms caught was compared and correlated with rainfall data (Spearman - p<0.05), using the accumulated averages for better characterization of the rainy season and summer. The parametric test, the Student's t-test, was used to compare the means and obtain the level of significance. In order to determine a relationship between shrimp production and seasonality, the monthly proportion of kg of shrimp caught was compared and correlated with the winter and summer periods. The shrimp production peaks of the three species are related to the annual rainfall peaks. The shrimp production in August 2017 surpassed the bycatch. The capture of pink shrimp, was the one that obtained significant variation in relation to the production between seasons. The seabob shrimp was the one that obtained the highest catch in kilograms and the highest abundance in the summer. The results of this work were important to generate the first information on shrimp production related to rainfall and seasonality of the southern coast of Pernambuco, contributing to the detection of sites with richness of species relevant for capture, for the conservation of shrimp and bycatch species, in addition to assisting in the targeting of fishing and control measures.
Avaliação da situação dos estoques de camarões capturados comercialmente no nordeste do Brasil com métodos para dados limitados

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.
