Aquaculture Nutrition, Journal Year: 2024, Volume and Issue: 2024, P. 1 - 24

Published: Jan. 11, 2024

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 converts waste into bioflocs, which serve food source shrimp within culture system, reducing need external inputs, such feed chemicals. Moreover, has potential improve yields economic performance while efficient resource utilization, energy. Despite its numerous advantages, presents several challenges, high energy demand, initial/running costs, (effluent, suspended solids, sludge) management, opportunistic pathogens (vibrio) spread, lack understanding operational/aquatic/microbial dynamics. However, with further training, research, innovation, be overcome, become more widely understood adopted technique, acting an effective method aquaculture. In summary, offers option promotes circularity practices enhancing benefits. This technique address faced ensuring continued growth protecting environment. A broad adoption contribute meeting industry’s impact resources. this context, review provides overview advantages highlights key technical, biological, aspects optimize application, promote adoption, overcome current challenges.

Evaluation of Probiotic Effects on the Growth Performance and Microbiome of Nile Tilapia (Oreochromis niloticus) in a High‐Density Biofloc System

Aquaculture Nutrition, Journal Year: 2025, Volume and Issue: 2025(1)

Published: Jan. 1, 2025

Biofloc technology is an aquaculture production system that has gained popularity with tilapia production. Probiotics provide benefits for the host and/or aquatic environments by both regulating and modulating microbial communities their metabolites. When a probiotic feed combined biofloc system, amount may be improved through better fish growth, disease resistance, water quality reducing organic matter stabilizing metrics such as pH components of nitrogen cycle. Two research trials measured Nile ( Oreochromis niloticus ) growth performance composition in within fecal material, following feeding top‐coated treatments. Trial A incorporated (71.4 ± 4.4 g), commercial diet (Control) was top coated either Bacillus velenzensis AP193 (AP193; 1 × 10 7 CFU g BiOWiSH Feedbuilder Syn3 (BW; 3.6 4 −1 ). In B, juvenile (5.34 0.42 g) were fed treatment diets two different concentrations at final (BWx1) 7.2 (BWx2). Tilapia offered (38% protein floating feed) control trials. Results from indicated no differences due to additions, except conversion ratio (FCR) B. Both BWx1 BWx2 showed survival, quality, solids management, bacterial matter. Even though results presented significant differences, could differ based on concentration, route administration, or impact community culture water. testing larger scale varied doses necessary achieve effective dosage improving performance.

Biofloc: A sustainable alternative for improving the production of farmed cyprinid species

Aquaculture Reports, Journal Year: 2023, Volume and Issue: 33, P. 101748 - 101748

Published: Sept. 28, 2023

As the global population continues its rapid growth, it has become imperative to expand aquaculture in order meet ever-increasing demand for food. Currently, carp farming comprises roughly 50% of all inland water production, with a range crucial species utilized this industry including grass (Ctenopharyngodon idella), silver (Hypophthalmichthys molitrix), common (Cyprinus carpio), bighead nobilis), catla (Catla catla), and rohu (Labeo rohita). However, ensure long-term sustainability farming, is vital adopt environmentally friendly systems explore alternative strategies. One such strategy that holds great promise biofloc technology (BFT), known effectively controlling toxic metabolites through introduction suitable cost-effective carbohydrate source into culture system. Bioflocs form unique ecosystems characterized by densely packed particles suspended poor quality, yet rich crude protein, essential minerals, fatty acids are highly beneficial nutrition. The presence bioflocs associated microorganisms rearing system directly influences various aspects growth performance, biochemical composition, immune responses, antioxidant states, digestive enzymes. This comprehensive review emphasizes importance BFT aquaculture, delving key topics as impact on antioxidants, body composition within By embracing BFT, can pursue sustainable effective approach expanding improving production while simultaneously mitigating environmental impact. actively promoting implementing use take significant strides toward more eco-friendly future.

Effect of Biofloc Culture on the Daily Rhythmicity of the Activity and Expression of Digestive Enzymes in Tilapia, Oreochromis niloticus

Aquaculture Nutrition, Journal Year: 2025, Volume and Issue: 2025(1)

Published: Jan. 1, 2025

Biofloc technology (BFT) has recently attracted great attention due to minimal water exchange and reduced feed intake. This study aimed recognize daily changes in the digestive physiology of Oreochromis niloticus between a traditional system BFT. The enzyme activity trypsin (try), chymotrypsin (chy), leucine aminopeptidase (lap), alkaline proteases (alk), lipase (lip), amylase (amy), along with gene expression ( try ), chy pepsin pep amy phospholipase pla ) were measured throughout cycle. Samples taken every 4 h 24 cycle under 12:12 L:D photoperiod. During 60 days, fish three times day (zeitgeber time, ZT: 0, 4, 8) fishmeal‐based diet containing 32% crude protein 5% lipid, where molasses was added as carbon source No significant differences found performance among treatments at end experiment. all tested enzymes significantly p < 0.05) increases during dark period both treatments, same pattern lip. maximum levels show marked effect dependent on presence light phases. cosinor analysis showed an try, lap, lip rhythmicity 0.05). Our results demonstrate that some processes related tilapia respond directly are modified constant These findings should be considered when establishing new optimized culture protocols.
