Item Vivência na Fazenda Primar Aquacultura: sistema multitrófico integrado de ostras com camarão(2022-09-19) Silva, Magna dos Santos; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/5881712638842687O presente trabalho teve como objetivo descrever as experiências adquirida na fazenda Primar Aquacultura. O Estágio Supervisionado Obrigatório, componente necessário para a obtenção do título de Bacharelado em Engenharia de Pesca, realizado na fazenda Primar Aquacultura localizada na cidade de Tibau do Sul no estado do Rio grande do Norte durante o período de 27 de junho a 02 de setembro 2022. Durante esse período foi acompanhado algumas atividades como, manejo das ostras Crassostrea gasar e suas diferentes fases de cultivo sendo, 1° estágio das sementes no campo upweller, 2° estágio travesseiros flutuantes em malha de 4mm no viveiro 11 e 3° em malhas de 9mm no canal 3. As diferentes etapas no cultivo de camarão Litopenaeus vannamei sendo elas, a aquisição das pós-larva, aclimatação, alimentação, despesca e comercialização, bem como a produção e manejo de microalgas, qualidade de água e avaliação da comunidade fitoplanctônica nos viveiros de ostras e camarão. A vivência adquirida foi de fundamental importância para meu crescimento profissional, como Engenheira de Pesca, aliando prática a teoria.Item Efeito de diferentes densidades de estocagem no cultivo de camarão marinho Litopenaeus vannamei (BOONE, 1931) em água oligohalina em sistema de bioflocos(2020-03-31) Santos, Ivanilson de Lima; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/1174538900783101The present study aimed at evaluating the production of marine shrimp Litopenaeus vannamei in oligohaline waters in a biofloco system under different stocking densities. The experiment was carried out in Laboratório de Experimentação com Organismos Aquáticos (LEOA/UAST) of the Federal Rural University of Pernambuco (UFRPE) for 90 days. The experimental design was completely randomized implemented with three stocking densities, 80, 160, and 320 shrimp.m-3 , with four replications. A total of 12 tanks were used, supplied with 800 L of water. The shrimp, with an initial weight of 0.038±0.001 g, were fed daily with commercial feed containing 35% of crude protein, with a frequency of 3 times a day and feeding at an initial rate of 10% of shrimp biomass and was adjusted according to consumption. Sugar was added to provide a daily maintain the 15:1 ratio (C: N). During the cultivation, the physicochemical variables of water quality such as temperature, dissolved oxygen, salinity, pH, total ammoniacal nitrogen, nitrite, nitrate, inorganic phosphate, total hardness, alkalinity, turbidity, settling solids, total suspended solids were measured. The zootechnical performance of juvenile shrimp was evaluated using the variables of final weight, feed conversion ratio, specific growth rate, final biomass, production, productivity, and survival. No statistical differences (p>0.05) were found in the means values of water quality variables (temperature, dissolved oxygen, pH, salinity) observed daily, as well as in the weekly variables (total ammonium nitrogen, nitrite, nitrate, phosphate, alkalinity, hardness, total suspended solids). However, turbidity from D320 was significantly higher than D80 and D160 (p<0.05); settled solids from D320 and D160 were higher than D80 (p<0.05). Most variables were within ideal values, except total suspended solids (265- 2645mg.L-1 ) and temperature (22-24°C). The density of 320 shrimp.m-3 recorded final biomass (205.63±100.83g.m-3 ), production (178.4±39.10shrimp.m-3 ), and productivity (258.67±126.01g.m-3 ) significantly higher than D80 and D160 (p<0,05). Although the low water temperature and high accumulation of total suspended solids, all treatments recorded survival above 50% and low feed conversion. The production of L. vannamei in well water using biofloc is a promising sustainable alternative. However, further studies should be carried out for a better understanding of this system.Item Produção de camarão marinho Litopenaeus vannamei (Boone, 1931) em sistema super intensivo com tecnologia de biofloco na Estação Marinha de Aquicultura da Universidade Federal do Rio Grande(2020-09-21) Morais, Julio Gabriel Cordeiro de; Silva, Ugo Lima; http://lattes.cnpq.br/1858876631961029; http://lattes.cnpq.br/2106503604382871This work aimed to describe how activities performed during the period of Mandatory Supervised Internship, required for examining a Bachelor's degree in Fisheries Engineering. This way, it presents the experience acquired in the production of Pacific white shrimp (Litopenaeus vannamei) in biofloc technology (BFT), with low water exchange. The internship took place at the Marine Aquaculture Station of the Federal University of Rio Grande (EMA-FURG), from March 16th to May 27th, in 2020. It was possible to monitor the activities and identify the infrastructure needed for the production and the grow-out phase of the shrimp in BFT, from the acquisition of the juveniles until the harvesting of the animals. Several management procedures were also realized, such as calculations related to feeding management, liming, and fertilization, as well as their applications, water quality monitoring, data analyses for decision making, among other activities. Participations in different scientific experiments were also carried out in the Station, further expanding the experience and knowledge acquired, which provided a professional improvement and a practical application of theoretical knowledge.
