After a 15-day acclimation period, during which the fish were maintained in 250-liter tanks, they were transferred to 40-liter experimental units at a density of 250 fish/m³ each. The hydroalcoholic extract of Anacardium occidentale bark was added to the diets administered to the animals at concentrations determined in the minimum inhibitory concentration (MIC) assays. Four treatments were evaluated: (i) commercial feed with 3% A. occidentale extract, (ii) commercial feed with 4% A. occidentale extract, (iii) commercial feed with 5% A. occidentale extract, and (iv) control group (commercial feed without extract addition), all with four replicates each. The experiment lasted 30 days, and the diets were offered three times a day (08:00, 12:00, and 16:00 hours) to apparent satiety. For histological analysis, five fish were collected at the beginning and one fish at the end of the experimental period (one per replicate for each treatment). The intestines were exposed in Petri dishes and divided into three segments: anterior, middle, and posterior. A 3 cm portion of the middle intestine was used, which was longitudinally cut to expose the villi. The total height, height, width, and thickness of the villi were measured. As a result, higher mean values for all intestinal morphology variables evaluated (height, total height, thickness, and width of the villi) were observed in the groups supplemented with 3%, 4%, and 5% of the hydroalcoholic extract of A. occidentale bark compared to the control group, with no differences among the treatments that received the extract. In conclusion, the supplemental use of the hydroalcoholic extract of Anacardium occidentale bark in the diet of Nile tilapia fingerlings resulted in a beneficial effect on the intestinal morphology of the supplemented animals, indicating improved development regarding intestinal health.Item Hábito alimentar da albacora branca (Thunnus alalunga) no Atlântico Sul Equatorial(2024-09-13) Sales, Vitória Carolina Dantas de Lima; Travassos, Paulo Eurico Pires Ferreira; Martins, Karla Mirella de Assis Bezerra; http://lattes.cnpq.br/9517816256433091; http://lattes.cnpq.br/0623255059511945; http://lattes.cnpq.br/4294200793056597Item Obtenção e caracterização físico-química e nutricional de concentrado proteico oriundo de resíduos de filetagem de saramunete, Pseudupeneus maculatus (Bloch, 1793)(2024-06-06) Amaral, Rodrigo Pinheiro Crasto; Oliveira Filho, Paulo Roberto Campagnoli de; http://lattes.cnpq.br/8043850276929205; http://lattes.cnpq.br/5798261290131048The aim of the present study was to obtain and characterize the protein concentrate of saramunete filleting waste, Pseudupeneus maculatus. Two types of saramunete protein concentrate (CPS) were developed, type A and type B, which can be differentiated by color and odor, evaluating yield, pH, water activity, chromatic coordinates, volatile nitrogen bases, humidity, protein, fat and ash.. The type A saramunete protein concentrate showed lower yield, despite being more acidic (lower pH) and higher L* value (brightness), lower a* value (red/green) and higher b* value (yellow/blue) than CPS type B. The water activity, moisture percentage and volatile nitrogen bases of CPS were low and with no difference between treatments. CPS type A had a higher percentage of protein, indicating better protein quality. Furthermore, it presented a lower amount of lipids, indicating that it is less susceptible to lipid oxidation. Therefore, type A CPS is a good way to add value to saramunete waste as it presents a good CPS yield, appreciable physical-chemical characteristics and nutritional aspects compatible with other fish protein concentrates, having potential for use in food products.Item Equiparação de atividade de Programa de Iniciação Científica (PIBIC): relatório final sobre avaliação da Tecnologia do ultrassom sobre aspectos físicos, químicos e nutricionais de filés de tilápias do Nilo (Oreochromis niloticus)(2024-06-06) Silva, Eloá Dandara Carvalho da; Oliveira Filho, Paulo Roberto Campagnoli de; http://lattes.cnpq.br/8043850276929205; http://lattes.cnpq.br/2682308411839274Item Acompanhamento atividades de pesquisas em biologia reprodutiva Anisotremus surinamensis (Bloch, 1791) capturado no litoral norte de Pernambuco, Brasil(2021-07-16) Leite, Rafael Barros; Oliveira, Paulo Guilherme Vasconcelos de; http://lattes.cnpq.br/5700488412022830; http://lattes.cnpq.br/3233322973038222Item Estágio Supervisionado Obrigatório no Centro de Referência em Aquicultura e Recursos Pesqueiros de Itiúba, Alagoas, Brasil(2024-08-30) Neves, Geiciele Guimarães; Medeiros, Mateus Vitória; http://lattes.cnpq.br/2723228592205339; http://lattes.cnpq.br/7111662517668148Item 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/1810381478994494The 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.Item Cultivo de camarão marinho (Litopenaeus vannamei) em baixa salinidade na Fazenda Aquicultura Tapacurá, São Lourenço da Mata - PE(2023-09-20) Ferreira, Danilo de Souza; Silva, Luis Otávio Brito da; http://lattes.cnpq.br/3365265235618078; http://lattes.cnpq.br/5295574324521332Item Estágio Supervisionado Obrigatório no Laboratório de Carcinicultura - DEPAQ(2023-09-20) Amaral Neto, Arnaldo; Silva, Luis Otávio Brito da; http://lattes.cnpq.br/3365265235618078; http://lattes.cnpq.br/8846230390675667
