In a 30-day experiment, Farfantepenaeus brasiliensis PL25 (25 ± 10 mg; 17.9 1.6 mm) were raised in nine circular floating cages with stocking density of 1000 shrimp m−3. Three treatments evaluated: (1) culture BFT system plus commercial feed supply (BFT+CF); (2) without (BFT) and (3) clear water (control). Post-larvae (PL) final weight (218.9, 236.5 176.0 mg, for BFT+CF, control respectively), biomass (17.9, 15.7 8.2 g) gain (193.9, 211.5 151.0 mg) similar the regardless whether they fed...

Abstract The continuous development of world aquaculture demands new strategies and alternatives aimed to achieve sustainability. use or microorganisms in has greatly evolved during the last two decades. From being considered as a potential threat, years, they have been used probiotics inclusively food source for fish crustacean. microbial‐based systems represent one most viable sustainable aquaculture. In short, these are based on promotion microbial proliferation, either autotrophic...

Microorganisms (MOs) are an important member of any aquaculture system. The MOs in the BFT (Biofloc Technology) system also crucial, diverse and therefore have different roles. This study reviews importance biofloc organisms (BFOs) BFT, factors affecting their population compositions, impact BFOs on water quality, applications as food source for cultivated aquatic species. Common often include photoautotrophic (e.g. microalgae), chemoautotrophic nitrifying bacteria), heterotrophic organisms,...

Aquaculture is a crucial industry that can help meet the increasing demand for aquatic protein products and provide employment opportunities in coastal areas beyond. If incorrectly manage, traditional aquaculture methods have negative impacts on environment natural resources, including water pollution overuse of wild fish stocks as aquafeed ingredients. Biofloc technology (BFT) may offer promising solution to some these challenges by promoting cleaner sustainable production system. BFT...

Farfantepenaeus paulensis juveniles (72 ± 24 mg), were reared in a suspended microbial flocs system and fed practical diets containing increasing amounts of crude protein (250, 300, 350, 400 450 g kg−1 CP). Development was promoted by high aeration rates fertilization with wheat bran molasses. Flocs composed detritus the form flocculated matter colonized heterotrophic bacteria, cocoid filamentous cyanobacteria, flagellate ciliate protozoa rotifers. Proximate composition analysis floc showed...

Globally, aquaculture, especially shrimp farming, plays an important economic role. However, it is known that traditional farming could negatively create environment impacts (e.g. due to water discharge into coastal areas and marine habitats), if good management practices are not followed. For these problems be minimized, the industry needs develop implement technologies promote sustainable aquaculture. Among different techniques, biofloc technology (BFT) system and, more recently,...

The goal of this study was to identify and estimate the abundance microorganisms associated biofloc culture system, developed from a 'macrocosm-microcosm' system type.In first section (cylinder 1000 L), 75 juveniles tilapias were inoculated with 5.0 ± 0.95 cm mean length 4.2 1.08 g weight placed.Daily, fishes fed commercial diet, maintaining C/N = 15:1 ratio, carbon (molasses rice dust) nitrogen (from feed) supply controlled.This condition maintained during 14 weeks.Several flocs identified...

Several studies have been performed adjusting the levels of dietary digestible protein and energy for tilapia, but none them was in biofloc technology (BFT) system, especially brackish (10) water. In this sense, three (22, 26 30% DP) (3000, 3150 3300 kcal DE / kg) were evaluated on growth performance, body composition, hematological parameters planktonic community juveniles Nile tilapia (O. niloticus) raised under BFT conditions. A total 540 fingerlings (GIFT strain with 1.25 ± 0.15 g...

Abstract The accelerated growth of aquaculture has caused environmental impacts in many countries. Examples include the use large volumes water, discharge effluents with high nutrient content, occupation areas, natural habitat alternation and escape exotic species. Biofloc technology (BFT) is an tool that requires minimal water exchange, promotes recycling optimizing resources produces food situ by forming suspended microbial aggregates (bioflocs). These microorganisms provide multiple...

Aquaculture is a growing industry, but current practices and raw material utilization must be reviewed to ensure resilient sustainable development. In this sense, the transition from linear economy (take, make, dispose) circular one (renew, remake) accelerating. The biofloc technology (BFT) relatively new cultivation system that can adopted accomplish more aquaculture circularity goals. This document discusses BFT its association with (CE), challenges, role of in overcoming those challenges....

The floc system has been successfully applied for shrimp grow-out, but little is known about contribution on reproductive performance. In a 30-day trial, spawning performance of broodstock was evaluated in and earthen ponds. Floc spawners achieved better results (P < 0.05) compared with pond terms number spawns per ablated female (2.9 vs. 1.3), (3.6 2.4) consecutive maturation (average 3.6 times 2.5 ponds females). Latency period lower (7.4 days) than (10.7 0.05). percentage females that...

A 45-day trial was performed to evaluate the effect of biofloc technology (BFT) with or without fresh food (FF) supplementation during pre-maturation period on Farfantepenaeus duorarum spawning performance, biochemical composition and fatty acid profile eggs as compared conventional clear-water system (CW+FF). Females raised in that received FF (FLOC+FF) achieved better performance terms number per spawn (49 × 103), g spawner's body weight (2.1 103) egg size (~275 μm) CW+FF (23 103, 1.1 103...
