The aquafeed industry evolved alongside fish farming, utilizing scientific and technological advancements to incorporate a variety of feed additives, supplements, alternative ingredients in the nutrition feeding aquaculture. These advances played significant role improving production, health, welfare farmed fish. Recent research Brazil highlighted importance using such as vitamins, minerals, amino acids, ensure that receive all necessary nutrients for growth health. Functional additives can...
Ultrasonography has been increasingly used in aquaculture breeding programs for non-invasive determination of sex and the gonad maturation stage fish. For first time, this image exam was performed on a mugilid (Lebranche mullet). Nineteen male 12 female fish were submitted to evaluation, which selected because they identified be final stage, previously confirmed through spermiation by abdominal pressure ovarian sampling biopsy (oocytes 626 ± μm), respectively. The ultrasound images obtained...
Resumo No Brasil, a tainha Lebranche é espécie Mugilidae mais importante para indústria pesqueira. Contudo, recentemente foi recomendada classificação como quase ameaçada. Neste sentido, aquicultura surge uma ferramenta poderosa conservação e desenvolvimento dos recursos naturais. O presente estudo avaliou influência de diferentes temperaturas durante larvicultura Mugil liza seus efeitos tardios no gonadal na quantificação hormonal após 24 meses. Inicialmente, os ovos fecundados (45 L-1)...
Abstract In Brazil, the Lebranche mullet is most important Mugilidae species for fishing industry. However, recently, has been recommended classification as near threatened. this sense, aquaculture emerged a powerful tool natural resource conservation and development. The present study evaluated influence of different temperatures during Mugil liza larviculture their late effects on gonadal development hormonal quantification after 24 months. fertilized eggs (45 L-1) were initially kept in...
Biofloc systems rely on microbial processes in the water column to recycle animal waste products, reducing need for exchange. These increases biofloc concentration and some form of removal is needed. An experiment was carried out evaluate two management practices control Litopenaeus vannamei culture. Six tanks (48 m3) were divided into treatments: exchange solid settler. Shrimp stocked at 164 shrimp m−2 with 0.67 g weight. After 61 days, under settler treatment demonstrated mean weight 12.7...
This study verified the effects of feeding frequency on growth, blood metabolites, digestive enzyme activities (alkaline protease, acid amylase and lipase) proximate composition Lebranche mullet juveniles. Fish with initial weight 13.6 ± 0.7 g were distributed in twelve tanks fed one, three, five seven times per day to apparent satiation for 60 days. While final fish only once a attained just 15.4 g, those or reached 54.0 12.1 55.9 6.1 respectively. The feed consumption also increased at...
Mugil liza juveniles (6.69 ± 0.06 g) were subjected to dietary citral (0-control, 0.5, 1.0 and 2.0 mL per kg feed) for 45 days, its possible effects on zootechnical metabolic parameters, digestive enzymes, innate immunity, oxidative status liver damage evaluated. At the end of experiment, fish fed feed showed a greater weight gain protein retention efficiency, as well enhanced activities pepsin (stomach) amylase (intestine) compared with control fish. Citral supplementation decreased...
The aim of the study was to evaluate influence changes in seawater salinity on juvenile Brazilian sardine (Sardinella brasiliensis). Through two assays, LC50 (96 h) and zootechnical performance (42 days) were determined, respectively. In first assay, six treatments 0, 7, 14, 21, 28 35 parts per thousand (ppt) with three replicates established. For this, 100-L cylinder-conical tanks used, 30 individuals 45-day after eclosion (DAE) unit, without water renewal feeding. groups 0 7 ppt, all fish...
Microalgae have great biotechnological potential but the high cost of traditional formulae culture media is one limiting factors to their commercial cultivation. As an alternative, use residual water from other activities has been proposed as a medium. The goal this study was produce Chaetoceros muelleri, Nannochloropsis oculata and Tetraselmis chuii biomass using intensive Litopenaeus vannamei biofloc cultivation system verify ammoniacal nitrogen, nitrite, nitrate orthophosphate...
The feed provided to breeding fish is one of the main factors influencing quality gametes. This study was carried out evaluate influence ascorbic acid on growth, haematological parameters and sperm Lebranche mullet males (Mugil liza). Six diets with different levels (0; 53; 107; 216; 482 708 mg/kg) were tested in triplicate for 75 days. During spermiation (first gonadal maturation), 144 individuals (205.7 ± 11.5 g 25.7 0.4 cm) randomly distributed 18 experimental tanks. Growth evaluated at...
ABSTRACT This study aimed to evaluate the effect of different levels omega-3 polyunsaturated fatty acids (n-3 PUFA) in diet Sardinella brasiliensis on their hematological parameters. A total 375 fish were distributed 15 experimental units effects blood for 45 days. The n-3 PUFA added 0, 0.3, 0.6, 0.9, and 1.2% lipid fraction. These values represent percentage fraction diet, 0% was used as negative control. Five from each unit sampled at end experiment analysis, parameters measured include...
The aim of this study was to investigate the ideal density use in transport operations for Brazilian sardines Sardinella brasiliensis (Steindachner, 1879). For purpose, 4,020 juveniles S. (0.51 ± 0.10 g and 3.89 0.32 cm) were randomly distributed 60L-polyethylene bags filled with 20 L water (salinity 35 g/kg) at densities 15, 10, 5, 2.5 1 g∙L-1, all triplicate. inflated pure oxygen (about ⅔) sealed elastic bands. duration simulated 24 h. Then, survival rate, as well analyses quality,...
This study evaluated the effects of dietary supplementation with citral on growth performance and intestinal parameters, specific activity digestive enzymes Sardinella brasiliensis. 240 juvenile S. brasiliensis were randomly distributed in a recirculating aquaculture system (RAS) composed 12 circular tanks 150 L (n = 20 per tank). A diet without addition (control) three diets containing different levels inclusion (0.5, 1.0 2.0 mL kg*feed–1) used fish feeding management during days. The...
In one year, 76 first generation (F1) Brazilian sardine Sardinella brasiliensis breeders spawned 84 times spontaneously in captivity. This is the report for genus Sardinella. Following pattern found natural environment, number of spawns, as well fertilization and hatching rates were higher spring, summer fall than winter. Until now, winter spawning was only presumed to occur a environment. Water temperature, not photoperiod, positively correlated with reproductive performance.
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...
