(2018) Santos, Jorge Luiz da Silva; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/3650685131155739
The objective of this work was to determine the main components of planktonic food in the nursery of shrimp L. vannameiwith biofloc technology. The experiment was carried out for 28 days and a randomized design with three post-larval storage densities, D2: 2 PLs. L-1, D4: 4 PLs. L-1and D6: 6 PLs.L-1, with four replicates each, using molasses as carbon source, in the C: N ratio of 15: 1. Samples were collected weekly, with 2 liters of water in each tank, which were filtered with plankton net and concentrated in 250 mL. The qualitative and quantitative study of plankton with 1 mL sub-samples for zooplankton was carried out in the Sedgwick-Rafter chamber (ind.L-1). The phytoplankton was evaluated in slides and coverslips (nº cells.mL-1) analyzing 0,1 mL, bothunder light microscope. The temperature values remained close to 22 ° C, below the ideal temperature for L. vannameicultivation, since the appropriate range for this species is between 26 to 33ºC, but the dissolved oxygen was in the ideal conditions for its culture, which should be above 4.0 mg.L-1and during the experiment remained above 8 mg.L-1. The development of shrimp did not show any difference between the treatments, for the final weight variable, since the survival, the D2treatment obtained the highest survival (> 72%) and the production in D6was higher than in the other treatments (2.98 Pls.L-1). The zooplankton community in the nursery tanks was represented by 23 genera, distributed among the groups Rotifera, Protozoa, Nematoda, Platelmintos and Cladocera. The Protozoa group presented the most diversification, regardless of the treatment, and also presented the highest abundance (> 66%). The main genera of Protozoa were Aspidisca, Euplotesand Trinema, and the phytoplankton community was composed of 16 genera, distributed in the classes Chlorophyceae, Bacillariophyta, Cyanophyceaeand Dinophyceae, the dominant class was Bacillariophyta(> 41%), with the genera Naviculaand Cyclotella. The density of 4 PL.L-1gave the highest density of zooplankton, but for the phytoplankton the density of 6 PLs.L-1was the one with the highest amount.

(2018) Silva, Joyce Carla Carvalho da; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/5764032184191409
The objective of this work was to evaluate the cultivation of Litopenaeus vannamei shrimp during the nursery phase in a biofloque system and zero water exchange using molasses, wheat, cassava and sugar sources. The experiment was conducted at the Laboratory of Experimentation of Aquatic Organisms, Serra Talhada, PE, Brazil. The shrimp nursery was held during 45 days of cultivation. A total of 20 circular polyethylene tanks with an area of 0.05107 m2, supplied with 15 L were used, with no water renewal and constant aeration using radial compressor (120 W) and porous stones. It was adopted a completely randomized design with 5 treatments and 4 replicates, by adding four carbon sources: molasses (ME), sugar (AC), manioc starch (FM), wheat flour (FT) and a treatment control (CT) without the application of carbon sources.The carbon sources were applied daily in the treatments (ME, AC, FE and TR) in a ratio carbon (C) and nitrogen (N): 15: 1. L. vannamei post-larvae with a mean weight of 0.2 g were populated with 8 animals per culture tanks at a density of 156.6 shrimp / m2. The shrimp were fed daily at a frequency of 3 times daily with a commercial feed containing 40% crude protein. During the period of the experiment, the physicochemical variables of the water were monitored: temperature (° C), dissolved oxygen (mg / L), electrical conductivity (mS / cm), salinity (g / L),potential oxy-reduction (mV), total dissolved solids (mg / L), and Hydrogenion potential.The use of carbon sources did not influence the mean values of the physico-chemical variables of water quality, being satisfactory to the good development of the prawn larvae. At the end of the cultivation, the zootechnical performance with respect to survival, final biomass and feed conversion factor presented significantly better values with the use of cassava and wheat flour as carbon sources.

The present work evaluated the culture of the marine shrimp Litopenaeus vannameiin the nursery stage submitted to different storage densities in a biofloco system. The cultivation of post-larvae of L. vannameimarine shrimp in biofloc technology was carried out at the Laboratory of Experimentation of Aquatic Organisms of the Federal Rural University of Pernambuco (UFRPE), during the 28-day period. A completely randomized design with three treatments was adopted: D2: 2 shrimps. L-1, D4: 4 shrimps. L-1and D6: 6 shrimps. L-1, with four replicates. Twelve tanks with a useful volume of 15 L of water were used. As post-larvae with initial weight 0.005 ± 0.001 g were fed commercial feed containing 40% crude protein, with a frequency of 3 times a day and feed rate of 10% of the biomass. Fertilizations were done with the daily use of the maintenance schedule of 15: 1 (C: N). During the cultivation were monitored as having success and were identified the types of light and temperature (ºC), dissolved oxygen (mg L-1), conductivity (μS Cm-1), salinity (g L-1), pH, total dissolved solids, total ammoniacal nitrogen (N-NAT), nitrite (N-NO2), nitrate (N-NO3), inorganic phosphate (P-PO4), sedimentable solids (SS) and alkalinity. The performance of the post-larvae was obtained through the comparison of final weight (mg), survival (%), food replacement factor (FCA), condition index, TCE (% -1) and weekly growth (mg). Differences were found not to be a factorof feed conversion and of post-larvae production. Despite the final weight values, survival and weekly evolution differed significantly between treatments (P> 0.05). The results of the results, with respect to one crop were reached when cultivated in the post-larvae of 4 post-larvae L-1, as it was in many treatments (P <0.05). Biofloc technology is a good alternative for the shrimp nursery, bringing high productivity and greater sustainability, especially in semi-arid regions with little availability of water. The adoption of storage densities from 2000 to 6,000 PL. m-3of L. vannameidid not significantly influence the physical chemical variables of water quality.

(2018) Oliveira, Carlos Yure Barbosa de; Dantas, Danielli Matias de Macêdo; Olivera Gálvez, Alfredo; http://lattes.cnpq.br/7002327312102794; http://lattes.cnpq.br/3422902414863662; http://lattes.cnpq.br/3825860944561089
Microalgae and cyanobacteria are eukaryotes and prokaryotes, respectively, photosynthetic and use atmospheric CO2, light and inorganic compounds for their growth. In addition, they produce nutritional, bioactive compounds and some species mayproduce toxins (like some species of cyanobacteria and dinoflagellates). The present study aimed to identify and isolate species from the phytoplankton community of reservoirs located in the semiarid Pernambucano and later to evaluate the biotechnological potential of microorganisms previously isolated from the center of cultureof the Laboratório de Produção de Alimento Vivo (LAPVI-UFRPE/Sede). For the collection of these organisms a network with a mesh of 20μm was used, being part of the collected material fixed in formaldehyde to 4% and the rest submitted to the culture. After the sorting of all collected material, the canonical correspondence analysis was performed to evaluate possible interactions between the abiotic parameters and the species found. The evaluation of biotechnological potential occurred by the bioremediation capacity test of Chlorella vulgarisin effluent from a biofloc system (BFT). Twenty-one taxa were recorded, most of them of the class Chlorophyceae. Among the species found, we highlight the presence of Ceratium furcoides, an exotic dinoflagellate that is found in a growing geographic expansion in Brazil. In the evaluation of bioremediation potential, the presence of Chlorella vulgaris promoted a reduction in the levels of nitrogenous and phosphate compounds of the BFT effluent of approximately, 79.2% and 48%, respectively. In addition to the removal capacity of these compounds, BFT effluent presented as potential medium for the cultivation of this microalgae.

Aquaculture, an activity responsible for the cultivation of aquatic organisms, arises with great potential to supply food demand in the face of population growth. Among the activities of aquaculture production, shrimp farming is one of the most important, with Litopenaeus vannamei being the most cultivated in Brazil, mainly in the Northeast region. Thus, the objective of this work was to experience and analyze the productive process of the cradle and fattening phases of the marine shrimp at Camar Camaramar Fazenda Camar Aquamaris, located in the city of João Pessoa -PB. It is possible to know the sectors of the farm, as well as the stages of production, among them the acquisition of post-larvae, preparation and management of nursery tanks, settlement, food management, monitoring of the physical-chemical parameters of water quality and the nursery tanks, as well as conducting an experiment with the use of bioremediation in the nursery stage. In the stage of fattening it was possible to follow the preparation of nursery, settlement, food management, biometrics, until the final phase of the nursery expenses. The experience on the farm made it possible to increase the knowledge about the practices involved in shrimp farming, especially in the nursery and fattening phase of the marine shrimp, providing a more technical and practical vision experienced in a shrimp farm, allowing personal and professional

(2018) Coêlho, Aureni Pereira; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/8354389878126055
The present study evaluated the reuse of water in four different experiments, where the first and second experiments were carried out with tilapia culture and third and fourth experiment with marine shrimp, respectively, with biofloc technology (BFT) in the raising and fattening stages of tilapia of the Nile (Oreochromis niloticus). Nursery and juvenile shrimp production (Litopenaeus vannamei). Water collection and analysis were carried outat the Laboratory of Experimentation with Aquatic Organisms at the facilities of the Federal Rural University of Pernambuco at the Serra Talhada Academic Unit in Serra Talhada, PE, Brazil. In the experiments with Nile tilapia were used 4 circular tanks ofglass fiber with capacity of 1000L with useful volume of 800L. In the experiments with marine shrimp, 4 circular polyethylene tanks with a capacity of 20L and a useful volume of 15L were used. Water quality was analyzed based on temperature, dissolved oxygen, pH, and salinity. For the water analysis, total ammonia, nitrite, nitrate, alkalinity and total suspended solids were also monitored. The data were statistically analyzed at a significance level of 5%. All the physical-chemical variables presented significant difference after their reuse, with the exception of ammonia. The reuse of the water presented chemical modifications throughout its uses. However, it can be concluded that it is possible to re-use it in other crops with very small replenishments, provided that there is adequate monitoring and management throughout the crop so that the physicochemical and biological variables of the water remain in line with that recommended for the species.

After the end of the internship, the importance of the practical activities for the professional training of the course graduates was well known, serving as a foundation to strengthen the learning process, contributing as a differential to the gain of experience, before entering the job market.
Cultivo de tilápia do Nilo (Oreochromis niloticus) em tanques rede, na Aquicultura JE, Malhada Grande - Bahia
(2018) Coêlho, Aureni Pereira; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/8354389878126055
This work describes the activities developed in the aquaculture fishery sector in aquaculture JE in the Malhada Grande Village, Paulo Afonso, BA. The cultivated species was the Nile tilapia (Oreochromis niloticus), the main species cultivated in the region and in Brazil. The internship was held during the period from June 1 to August 10, 2018, with a total workload of 300 hours. The activities developed were: monitoring of the facilities and maintenance of the tanks network; acquisition, acclimatization and settlement of fingerlings and juveniles; production and food management; biometric evaluation and expenditure. Fifteen tanks were harvested with pockets of 5 m3 and 4 mm mesh, containing 2.400 alevins with an average weight of 6 g. The realization of the settlement occurred early in the morning in an attempt to cause minimal stress to the animal. To prevent disease, a pre-release salt bath containing 5 to 10 g of salt per liter of water was performed. The biometric analyzes carried out during the cultivation occurred on a bi-weekly basis, in the classification process, pre-harvesting, or occasionally when irregularity was observed in the consumption of food. The data obtained served to regulate the amount of ration to be offered. The fingerlings (6 - 50 g) were fed every hour. When juveniles were fed, regardless of the mean weight, four times a day. Expenditure was started, which the fish were removed from the tanks with the aid of puçás after lifting on the raft and retraction of the screen, reducing the space and providing the removal of the animals faster. The animals were weighed, weighed until the desired amount was reached, and then the animals were placed in a ice-cold water box for hypothermia. Then in the fish box are added ice / fish / ice to ensure a good quality of freshness of the animal during transport. This stage was important to build new knowledge and put into practice the knowledge acquired throughout the academy, which was previously only theoretical.

Nowadays, the fishing industry has grown considerably, both by the increase of consumer demand and by the technological innovations. However, it is necessary to follow these innovations with the improvement in quality inspection and processing programs. The objective of the study was to evaluate the shelf-life, through physical-chemical, microbiological and sensorial analyzes of sausages elaborated with sea bream (Sciades herzbergii) stored under freezing (-20 ± 2ºC) for up to 4 months. The sausages presented increase (p <0.05) in lipid oxidation from 0.5 to 1.1 mg malonaldehyde / kg in up to 3 months and volatile nitrogen bases from 12.2 to 16.5 mg / 100g in up to 4 months storage. The water retention capacity of the frozen sausages did not change (p> 0.05), presenting an average of 85.0 ± 0.9%. The pH of the sausages decreased (p <0.05) from 6.4 to 6.0 after 2 months of freezing, presenting a slight increase after this period. The values of instrumental color L *, a * and b * decreased (p <0.05) from 62.1 to 56.4; 8.0 to 4.8; 10.2 to 7.2 after 4 months of storage, respectively. The frozen catfish meat sausages (-20 ° C) were <2 log CFU / g of thermotolerant coliforms (E. coli) and were absent in Salmonella sp during up to 4 months of storage. In the sensory evaluation, the color, odor, texture, flavor and overall acceptance received a grade equivalent to "moderately liked", with an acceptable rate of over 82%. It can be observed, therefore, that fresh type sausages made with sea catfish meat show little variation during 4 months of storage under freezing, being able to be a product with high potential of manufacture in commercial scale, thus adding value to a species of fish of low commercial value of the Brazilian coast.

Knowledge of the morphometricand reproductive aspects of Macrobrachiumamazonicum(HELLER, 1862) is a basic toolfor the elaboration of adequate management, conservation and exploitation strategies. The objective of the present study was to study the morphometricand reproductive aspects of M. amazonicumin the Cachoeira II reservoir, located in Serra Talhada, a mesoregion of the Pernambuco sertão. The prawns werecollected monthly between June 2016 and May 2017. From the morphometric measurements the relative growth was analyzed and classified as allometry. A macro and microscopic analysis atovaries was performed to classify the maturational stages and estimated the size of the first maturation. A total of 432 specimens (86 males and 346 females) were sampled. The sex ratio was statically different from 1: 1 in all months, in favor of females. The reproductive period of the studied population was continuous, with annual reproductive peaks between September and November beyond February, corresponding to the period of rainfall. Thefecundity ranged from 128 to 2724 eggs, being related to the size of the females. The largest specimen captured was male, measuring 87.13 mm, against 80.63 mm of the opposite sex.Six stages of development were found: immature, developing, developed, spawned in development, spawned and rested. Based on these analyzes the size of the first maturation of the females was identified in 9.46 mm of cephalothorax length and,soon,suggested as the minimum size of capture.

(2018) Temoteo Filho, Sérgio Roberto; Nunes, Diogo Martins; Vasconcelos Filho, Jonas Eloi; http://lattes.cnpq.br/4784149077807044; http://lattes.cnpq.br/0407093177034625; http://lattes.cnpq.br/8906640435895478
The otoliths are calcium carbonate structures located in the inner ear of fish, are considered as files that hold valuable information on the biology of fish. Each fish has three pairs of otolithslapillus, sagitta and asteristicus that have microstructure, size, shape and specific functions. The sagitta stands out, being easier to be located and having specific form and functions from species to species. The studies applied to the form of otoliths are research tools in the analysis of stomach contents, identification of stocks and population dynamics. Few scientific works were developed in order to know the ichthyofauna of deep waters in the archipelago of São Pedro and São Paulo (ASPSP). In this work, we used the image processing of the photos of the otoliths of the species captured in the ASPSP, in addition to the Fourier analysis to morphologically describe their aspects and thus characterize the otoliths sagitta of Polimoxia nobilis, Pontinus nigrpunctatus andPhysiculus sp. From the morphometric analysis, a comparison was made between the right and left side and the sex relating to the lengths of the otolith of P. nigropunctatususing Student's t-test and to describe the changes throughout life regressions were made between the measurements and the total length of the individual. The results showed changes in the sagitta otoliths of P. nigropunctatusrelated to the growth of the individual. These results were presented and discussed according to the applied methodology.

Brazilian shrimp farming has been gaining space and economically standing out as one of the pillars of agribusiness that most generate jobs. However, this sector has already faced several bouts of disease outbreaks, and was able to rebound, thanks to technological advances. The objective of this study was to follow the routine activities of Aquarium Aquiculture do Brasil Ltda, located in the rural area of Mossoró-RN (5 ° 06'24.1 "S 37 ° 17'41.8" W), in the period from 04 / 05/2018 to 11/07/2018, as well as corroborate with the professional training of the student. Among the activities developed in the compulsory supervised stage are: nursery preparation and drying; chlorination and liming of sluices and pools of water and soil;nursery fertilization; acclimatization and settlement of PLs; application of probiotics; application of molasses as carbon source; feeding; verification of feed consumptionand possible adjustments to the following breeding stock; weekly biometrics to accompany the average weekly growth of shrimp; verification of the physical-chemical parameters of the tanks, aiming at the well-being and development of the individuals; assessment of shrimp health, such as carapace rigidity and expense.All these activities have their importance in the productive process (fattening) and, combining the theoretical knowledge with the execution in the practice can promote the reduction of possible losses (by mortality) and increase of the productivity, seeking to optimize it. Following the technical guidelines for a good result in the production of marine prawns makes a great difference, both in the biosafety aspect and in the improvement of the zootechnical results of the prawns. In addition, the adoption of strategies to prevent diseases in animals is a very complex challenge, however, producers are joining forces with researchers to try to reverse the current situation of Brazilian shrimp farming. Therefore, the discussion formed throughout this work with scientific basis, brought to the fore the importance of carrying out the activities developed, both in the practical question, and their argument for understanding the importance in actions aimed at continuous improvement in order to contribute to the scenario of Brazilian shrimp farming.

With the initial aim of investigating the composition and catch rates of different trap models (rectangular large, rectangularmedium and conical) in the São Pedro e São PauloArchipelago region in waters above 200 m, 14 exploratory campaigns were carried out in the period of 6 years (January 2012 to February 2018), comparing the CPUE values for selectivity variables,such as the [First Quarter (FiQ), Second Quarter (SQ), Third Quarter (TQ) and Fourth Quarter (FQ)], depth extract(200 to 700 m), immersion time (I -up to 12h, II -between 13 and 20 h and III -above 20 h) and bait [head of tuna, cangulo, xaréu and mixed (cangulo and xaréu)]provided by the vessel. The catch rates, expressed in terms of CPUE (individuals / trap), were analyzed for each factor separately and among the trap models used. As a result, 1135 specimens were captured, divided into 18 distinct species.Among the species collected, the African crab (Chaceon gordonae) was a more abundant species, with a relative participation of 61.76% of the catches. A significant difference was observed between the LargeRectangular Trap (LRT) and the Conical Trap (CT) (KW = 13.584; GL = 1; p= 0.0002281) Small Rectngular Trap (SRT) and CT(KW = 5.7909; GL = 1; p= 0.01611), whereas the rectangular shapes did not show any static difference between each other (KW = 1.0532; GL = 1;p= 0.3048). In the analysis of the CPUE values for bycatch(the other species captured), there was a significant difference between the LRTand SRT(KW = 22.619, GL = 1;p= 0.975x10-6) and for the ARP and AC (KW = 15.389; GL = 1;p= 6.897x10-5), but between the LRTand SRTthere was no statistical difference (KW = 1.7828; GL = 1;p= 0.2565). When analyzing the data for trap selectivity variables, for Target Species (TS), only a small significantdifference was observed for LRTwhen analyzing CPUE data for month variable (KW = 9.1554; GL = 3; p = 0.02729). In this way, the rectangular models are more efficient in relation to CTand statistically they are equal to each other. Thus SRTis the most suitable for capture in the SPSPAenvironment, due to the lower cost in its construction, because it is lighter and occupy less space in the vessel in relation to LRT.

The use of marine resources for various purposes has been used by society since the earliest times, consuming fish is among FAO's recommendations as an ideal for high-protein food. Faced with technological innovations and growth of industries, the beneficiation has much to add, from the moment the population proposes products that are easy to prepare, or semi-ready, which saves time at the time of preparation. This report describes some of the beneficiation activities at the company Qualimar Pescados, where shrimps, fish andlobsters are processed, these fish according to the type of processing can offer different types of final products. And it also discusses the standards of quality, marketing and other knowledge that a food industry has to offer.
