As the main species of freshwater shrimp farmed for commercial fins are Macrobrachium nipponense and Macrobrachium rosenbergii, due to their growing production or success in cultivating these animals is directly linked to the type of system to which they are being used. Thus, some alternative systems have emerged in order to minimize damage to the environment and increase the stocking density of animals, among them the biofloc cultivation (BFT - Biofloc Technology). Given the above, the objective was to evaluate the productive and zootechnical performance of Macrobrachium rosenbergii fed different levels of crude protein in autotrophic system and bioflocks during the nursery phase. The experiment obtained a completely randomized experimental design with a 2x2 factorial arrangement, the first factor being the different culture systems, clear water (AC) and bioflocks (BFT), and the second the protein levels of the diet (35 and 40%). Thus, obtaining the AC35, AC40, BFT35 and BFT40 treatments, with four replications for each treatment, the experiment lasted 80 days. The food offered to the animals was composed of commercial pelleted feed with 35% and 40% crude protein levels, offered three times a day. For water quality monitoring, temperature, dissolved oxygen and pH were measured twice a day (08: 00h and 16: 00h) with the aid of a multiparameter and ammonia, nitrite, nitrate, orthophosphate and sedimentable solids were measured weekly. The zootechnical performance of the shrimps was analyzed by weekly biometrics, where the parameters were measured as: final average weight, weight gain, feed conversion factor, final biomass and mortality. Data were analyzed using two-way variance (ANOVA) followed by the Tukey means comparison test at 5% probability using ASSISTAT version 7.6 software. The water quality variables of the different cultivation system (Biofloco and Água clear) were within the recommended levels for the optimal cultivation of the species. There was no significant effect on final average weight (FW), weight gain (WG) and specific growth rate (TBI); however, there was a significant difference (p <0.05) in relation to crude protein in the conversion factor. (FCA), survival (S) and final biomass (BF). Thus, it is concluded that the use of biofloc cultivation system allows the reduction of crude protein concentrations of the offered diet, without causing damage to the zootechnical performance variables of shrimp Macrobrachium rosenbergii, and may reduce the operating costs of the production system.Item Acompanhamento técnico da cadeia produtiva do camarão (Litopenaeus vannamei) realizado na Potiporã - Samaria Camarões LTDA(2019-02-01) Santos, Manoela do Rêgo Barros; Moura, Andrea Paiva Botelho Lapenda de; http://lattes.cnpq.br/6414540974581675; http://lattes.cnpq.br/1498292510891744Having the perception that the supervised internship required to obtain a Bachelor's Degree in Veterinary Medicine is the moment where there is the association between the theoretical knowledge acquired during the graduation with the daily practical experience, this final paper aims to report the experience of technical monitoring of the production of Pacific White Shrimp (Litopenaeus vannamei). The internship was carried out in the period between September 18, 2018 and December 5, 2018 in the company Potiporã - Samaria Camarões Ltda. The activities developed were carried out at the Post-Larva Unit, located in Touros-RN, at the Shrimp Farm and at the Beneficiation Unit of the company, both located in Pendências-RN. The practices were performed following the production flow chart of the company, starting at the Post-Larvae Unit, which has the objective of producing quality post-larvae, going to the Shrimp Farm, where the animals are cultivated for about 105 days and has an approximate production of six tons per hectare per year, and lastly, at the Processing Unit where procedures were followed from the animals in the nurseries until the final product (frozen shrimp) was sent to shopping centers. Each of these stages was supervised by Veterinary Roseli Pimentel Pinheiro e Silva, general manager of the post-larva unit and the company's technical manager. In total, the 420 hours hourly load scheduled for 08525 - Compulsory Supervised Internship of the Bachelor's Degree in Veterinary Medicine at Universidade Federal Rural de Pernambuco – UFRPE was completed, under the guidance of Professor Andrea Paiva Botelho Lapenda de Moura
