Item Relatório de Estágio Supervisionado Obrigatório(2019-01-29) Castro, Amanda Lucy Ferraz de; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086Item Crescimento de alevinos de Oreochromis niloticus em sistema de bioflocos e submetidos a diferentes níveis protéicos(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/7296152139446076Among 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.Item Relatório de Estágio Supervisionado Obrigatório - descrição do processamento para obtenção do filé de tilápia congelado(2018-08-23) Costa, Luiza Valença de Lima; Moura, Andrea Paiva Botelho Lapenda de; http://lattes.cnpq.br/6414540974581675; http://lattes.cnpq.br/3284974420344475The purpose of this Course Completion Work was to describe the practical and technical activities carried out between April 18, 2018 and July 31, 2018 at Qualimar Comércio de Importacao e Exportação, located in Jaboatão dos Guararapes (PE) , related to the Obligatory Supervised Internship Discipline. The activities described here were developed in the Quality Control Laboratory and in the Production Room of the processing unit, observing its operation and respecting its flow chart, with emphasis on the frozen fish fillet product, where the species used was the tilapia (Oreochrimis niloticus ) and all of its production process was followed, citing the direct and / or indirect performance of the quality control, starting from the reception, followed by the processing, packaging and finishing in the logistics. Each of these stages of activities was supervised by the Veterinarian Pedro Generino, responsible for the Quality Control of the company. The activities were carried out during the course 08525 - Compulsory Supervised Internship of the Bachelor's Degree in Veterinary Medicine, Federal Rural University of Pernambuco - UFRPE, under the guidance of Professor Andrea Paiva Botelho Lapenda de Moura. This stage was able to bring the experience of the fish processing industry, promoting technical knowledge related to this particular area of practice of the Veterinarian.
