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. 

Biofloc technology provides high productivity, low feed-conversion ratios and a stable culture environment. Also, with viral problems and rising costs for energy, biofloc technology can help deliver sustainable production at lower cost.
