Resumo: | Currently in shrimp farming, intensive system is a promising technique because it has greater biosecurity in relation to traditional culture, especially regarding the challenges with the White Spot Syndrome Virus (WSSV). The aim of this study was to evaluate the effect of the combined and isolated addition of Navicula sp. and Brachionus plicatilis on zootechnical performance, water quality, Vibrio concentration and WSSV infection of L. vannamei reared in nursery with biofloc system. The study was divided into two phases, the first phase consisting of four treatments: BFT (biofloc); BFT-N (BFT with the addition of Navicula sp.); BFT-B (BFT with the addition of Brachionus plicatilis) and; BFT-BN (BFT with the addition of Navicula sp. and Brachionus plicatilis), all in triplicate and; the second phase, it was constituted by viral challenge, also in triplicate. Shrimp (PL10, 2 mg) were randomly separated and distributed in the experimental tanks at 3000 shrimp m-³ and fed four times a day with a 45% protein commercial shrimp diet. Live food was added every 10 days at a density of 10x104 cel mL-1 for Navicula sp. and 30 org mL-1 for Brachionus plicatilis. After 45 days of experiment, the animals were infected with WSSV using minced tissue (21 days) at density of 300 cam m-³. Results indicate that for the first phase, final weight and yield were statistically significant for all treatments with isolated and combined addition of diatoms and rotifers. In this phase, there was a predominance of positive sucrose colonies in Vibrio quantification. Massive mortality rate was firstly achieved in control (BFT) and BFT-B treatments in the second phase. However, all treatments achieved 100% of mortality rate and the WSSV infection was confirmed by nested-PCR and histopathologically, with lesions suggestive of WSD (presence of nodules and tissue deformations). Although the addition of live food resulted in best zootechnical indexes of L. vannamei in intensive nursery system, in terms of resistance to WSSV infection, there was no reduction in infection and mortality rates in challenged animals under the experimental conditions examined. |

Sendo assim, o objetivo do estudo foi avaliar o efeito da adição conjunta e isolada de Navicula sp. e Brachionus plicatilis sob o desempenho zootécnico, qualidade da água, concentração de víbrios e resistência ao WSSV de L. vannamei cultivados na fase berçário em bioflocos. O trabalho foi dividido em duas fases, a primeira fase consistiu em quatro tratamentos: BFT (sistema biofloco); BFT-N (BFT com a adição de Navicula sp); BFT-B (BFT com a adição Brachionus plicatilis); BFT-BN (BFT com a adição de Navicula sp. e Brachionus plicatilis), todos em triplicata e; a segunda fase, constituída pelo desafio viral, também em triplicata. Os camarões (PL10, 2 mg) foram estocados na densidade de 3000 camarões m-³ e alimentados quatro vezes ao dia com ração comercial com 45% de proteína bruta. O alimento vivo foi adicionado a cada 10 dias na densidade de 10 x 104 cel mL-1 para Navicula sp. e 30 org mL-1 para o Brachionus plicatilis. Após 45 dias de cultivo, os animais foram submetidos ao desafio viral, durante 21 dias, na densidade de 300 cam m-³, com todos os tratamentos com e sem a inoculação de WSSV. Os resultados obtidos na primeira fase demonstraram diferença significativa no peso final e produtividade nos animais dos tratamentos que receberam adição isolada e conjunta da diatomácea e rotífero e a predominância de colônias com sacarose positiva na quantificação de Vibrio sp. Enquanto na segunda fase, observou-se que o tratamento controle e BFT-B alcançaram mortalidade total primeiramente. Entretanto, em todos os tratamentos houve perda total dos animais e a infecção por WSSV foi confirmada via nested-PCR e histopatologicamente, com a presença de nódulos e deformações teciduais causados pelo vírus. Em suma, embora o acréscimo do plâncton tenha resultado em melhores índices zootécnicos do L. vannamei no sistema de berçário intensivo, em termos de resistência à infecção por WSSV, não foram determinadas reduções nas taxas de infecção ou de mortalidade dos animais desafiados e infectados sob as condições experimentais avaliadas.Submitted by (ana.araujo@ufrpe.br) on 2024-03-12T17:12:45Z No. of bitstreams: 1 Allyne Elins Moreira da Silva.pdf: 1036728 bytes, checksum: 045321d320a8026ed4e9299225c66299 (MD5)Made available in DSpace on 2024-03-12T17:12:45Z (GMT).
