The Brazilian sardine is the most important fishery resource in Brazil. Their production has declined along last 30 years due overfishing, climatic and oceanographic phenomena. This study was carried out to determine optimal feeding frequency for juvenile based on growth, feed efficiency, intake body composition. Six frequencies of one, two, three, four, five six times a day were evaluated triplicate tanks 50 days. Fish with initial mean weight 3.29 ± 0.56 g fed daily apparent satiation....
A 6-week growth trial was conducted to evaluate the effects of feeding rate on performance, body composition, plasma metabolites and enzyme activities, determine optimal for juvenile Brazilian sardine. Fish were fed at six rates, 2, 4, 6, 8, 10% BWday−1 (body weight per day) until satiation (10.3% BWday−1). The survival fish 2%–6%BWday−1 significantly higher (p < .05) than other rates. final specific increased with increasing rates while feed utilization decreased. Total proteins,...
The common snook, Centropomus undecimalis, is an emerging species for intensive fish culture, however, some reproductive aspects of this species, especially the development testes and action androgen hormones on spermatogenesis have not been studied. objective study was to evaluate effects 17α-methyltestosterone (MT) steroidogenesis during first sexual maturation snook. fish, which were reproduced in captivity, had a body weight 305.80 ± 35.60 g total length 34,11 1,08 cm. We used...
The limited availability of live bait for capturing skipjack tuna, Katsuwonus pelamis, is a bottleneck to increasing tuna production in many parts the world. Therefore, nutrition trial was performed contribute Brazilian sardine, Sardinella brasiliensis, use as bait. This study determined best dietary carbohydrate lipid ratio (CHO:L) juvenile sardines based on growth performance, feed utilisation, body composition, blood metabolites and digestive enzyme activity. Six isoenergetic...
Aquaculture plays an important role in the world's productive, social, and economic growth. The production of low-trophic-level fish such as Clupeids, aimed at sustainable growth aquaculture industry, is a desirable promising strategy, considering that species represent approximately 30% global contribute directly to worldwide food security. consisting mainly herring, sardines, shads, anchovies, form one main fisheries resources oceans, use meal oil manufacture feed used nourish also affects...
A six-week growth trial was performed to estimate the dietary protein requirements for maximum of juvenile Brazilian sardine (Sardinella brasiliensis) based on performance, feed utilization, body composition and digestive enzyme activity. Six isoenergetic diets were formulated contain levels that increased from 250 500 g/kg. Each diet randomly assigned triplicate groups 160 fish with mean initial weight 0.93 ± 0.13 g, which fed four times a day apparent satiation. Growth tended increase in...
This study aimed to evaluate the tolerance of common snook Centropomus undecimalis larvae and juveniles exposed acute concentrations un-ionized ammonia for 96 h at 35g L−1 salinity, after 24 starvation. For that, 10 (20.85 ± 1.46 mm) 47 days post hatch (DPH) per experimental unit (1.5 L) were 0.00 0.00, 0.65 0.04, 1.29 0.09, 2.59 0.18, 3.88 0.27, 5.17 0.34, 6.47 0.43 mg NH3, in triplicates, 26.72 0.08°C, dissolved oxygen 5.72 0.10 pH 8.45 0.06. During this period, no mortalities observed....
A sardinha-verdadeira (Sardinella brasiliensis) é o principal recurso pesqueiro do Brasil, sustentando diretamente a indústria de enlatados, como matéria prima, e indiretamente pesca dos tunídeos, pois juvenis são utilizados isca-viva. UFSC, através Projeto Isca-Viva, vem desenvolvendo técnicas produção em cativeiro com vistas ao uso sustentável recurso, entretanto não existem informações sobre toxicidade compostos nitrogenados no cultivo desta espécie. O objetivo deste estudo foi estimar...
