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 Vibrio parahaemolyticus inativado por calor pode modular a atividade de fenoloxidases no hepatopâncreas do camarão Litopenaeus vannamei(2020-11-13) Barreto, Lucinda Andriele dos Santos; Buarque, Diego de Souza; http://lattes.cnpq.br/7609652740088882; http://lattes.cnpq.br/3420085906429620Carciniculture has grown in recent years, especially in Brazil for the shrimp Litopenaeus vannamei. However, infectious diseases represent a major threat to productivity, such as the disease caused by Vibrio parahaemolyticus, which is responsible for high mortality rates. Thus, some alternatives have been taken to understand the innate immunity in shrimp, such as the system prophenoloxidase (proPO) that detects the activity of phenoloxidases in the hepatopancreas of shrimp, whose modulation is carried out by pathogens. Therefore, the present study aims to analyze the effect of inactivated V. parahaemolyticus on the L. vannamei hepatopancreas phenoloxidase enzymes and to observe whether the activity of these enzymes can be modulated through a second challenge with activated V. parahaemolyticus. The effect of inactivated pathogen followed by live bacteria in the phenoloxidase enzymes were evaluated in crude hepatopancreas extracts, in these treatments (without V. parahaemolyticus inactivated, with V. parahaemolyticus inactivated, with V. parahaemolyticus alive, with V. parahaemolyticus inactivated by heat and V. parahaemolyticus live). The activities were measured by incubating the crude extracts with L-dopa (non-specific substrate) and Hydroquinone (specific substrate of laccase phenoloxidase enzymes) and tyrosinase phenoloxidase inhibitor (13 mg / mL tropolone). Then the effect of temperature (25 ° C - 85 ° C) on the activity of phenoloxidases was tested. The enzymatic activity of the inactivated Vibrio group followed by infection with live Vibrio was not significant in relation to the live Vibrio group, just as there was a negative activity modulation in the live vibrio group, determining that it decreases the activity to establish itself in the shrimp. In addition, the activity was slightly inhibited (32.3%) by tropolone and the residual activity showed that laccase enzymes may be present marjoritly in the hepatopancreas of L. vannamei. This indicates that most of the phenoloxidase enzymes are laccase and that few enzymes are tyrosinase and that live pathogen is able to decrease enzyme activity in order to settle in the shrimp and cause an infection. Therefore, it can be concluded that neither phenoloxidase-like enzymes activity was not modulated in hepatopancreas following inactivated V. parahaemolyticus nor these bacteria prevent the effects of the active pathogen in these enzymesItem 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.
