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.

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.

Probiotics and Phytobiotics as Dietary and Water Supplements in Biofloc Aquaculture Systems

Aquaculture Nutrition, Journal Year: 2024, Volume and Issue: 2024(1)

Published: Jan. 1, 2024

Biofloc technology (BFT) is a relatively new microbial-based cultivation system that can be adopted to accomplish more sustainable aquaculture and circularity goals. This review explores aspects of BFT integrating the utilization probiotics phytobiotics as dietary water supplements. scientific-based snapshot unpacks some physiological pathways brings literature on how these supplements boost quality, well aquatic species' growth, health, survival. Probiotics, live microorganisms confer health benefits host when administered in adequate dosage, are noted for their ability bolster animal defenses sustain quality farming conditions. Recent studies showcased selected bacteria, yeast, fungi, once added into biofloc-based systems enhance performance, act tool management protect fish crustaceans against diseases. On other hand, additives sourced from plants normally compounded feeds known growth animals. These contain plant-based substances/extracts play key role suppress inflammation, pathogens, also antioxidants. ingredients promote healthy gut microbiota, improve feed efficiency, turn genes responsible immunity improving disease resistance fish/shrimp.
