Evaluating three aeration systems showed that air-injector nozzles produced greater microorganism diversity, biofloc development, overall shrimp productivity. 

Study evaluates Nile tilapia in monoculture and polyculture with giant freshwater prawns in biofloc and recirculating aquaculture (RAS) conditions. 

This study evaluated the growth performance of the freshwater fish piracanjuba raised in biofloc and clear-water systems for 34 days. 

This study in an outdoor biofloc technology production system evaluated impacts on fish production indices, common microbial off-flavors and water quality dynamics for hybrid tilapia. 

This study evaluated the importance of aeration intensity for the nitrification process in biofilm in intensive biofloc technology aquaculture systems. 

A study determined the zootechnical performance of Pacific white shrimp under different light regimes. Shrimp exposed to light had better zootechnical parameters than those with reduced or no exposure. 

Juvenile carnivorous African catfish performed well in biofloc-based systems, which could help produce better quality and more disease-resistant seed of this important aquaculture species and support the expansion of African catfish farming industry. 

The economic and environmental performance of tilapia biofloc technology systems are compared against other conventional tilapia grow-out production systems, highlighting the merits of BFT as a competitive and sustainable alternative low-cost intensive feedlot technology. 

Chambo Fisheries, one of the world’s largest tilapia biofloc tank farms and the largest in Africa, has developed its own, on-farm production of specialized feeds and procedures to optimize feed applications and feeding rates. 

Chambo Fisheries, the world’s largest tilapia biofloc tank farm and the largest tank farm in Africa, has a multi-cohort, sequential, continuous production schedule. 

Shrimp nursery systems offer the shrimp industry an important opportunity to increase profits, by helping produce strong, healthy and uniform juveniles with significant potential for compensatory growth after their transfer for final pond grow-out. Biofloc technology and water quality are critical components of shrimp nursery systems. 

A study tested the use of biofloc technology to improve the productivity of the fathead minnow (Pimephales promelas) a commercially important baitfish in North America. 

A study was conducted to assess the feasibility to grow Channel catfish (Ictalurus punctatus) in an outdoor biofloc system during winter in a temperate zone. High biomasses of market-size channel catfish were successfully maintained through the winter with high survival and in good condition in both treatments. 

Facing emerging viral problems and rising energy costs, the use of biofloc technology in biosecure systems offers an answer for sustainable shrimp aquaculture. The main attributes of biofloc systems in reducing disease risk include the fact that low water exchange improves pathogen exclusion. 

Combining biofloc technology with bio-secure modular shrimp culture can make operations more sustainable and economically viable. For optimized biofloc production, lined ponds and reservoirs and high stocking densities are essential. Paddlewheel aerators keep dissolved-oxygen levels high.
