Highly controlled tank and raceway systems can help farmers raise postlarval shrimp to larger sizes before stocking in grow-out ponds. Raceways have recently been implemented for EMS management.
Fast growth and attractive market prices make wreckfish an interesting option among the new species considered for commercial aquaculture.
In order to monitor and compare the performance levels of shrimp, statistical modeling of comprehensive field data collection from many commercial shrimp operations.
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.
For two years of data, the effects of management, season, stocking density and salinity on the incidence of disease in northeastern Brazil’s shrimp farms were found to be highly significant.
Early biofloc-based culture systems in tanks in Brazil have given way to commercial-scale bioreactors housed in greenhouses that utilize water fertilization regimes, high-protein feeds and salinity controls.
Lobster cage culture has great potential in Indonesia. The current industry consists of about 1,000 small-scale farm units, many of which raise lobsters in polyculture with seaweed and grouper.
Work on the reproduction and larval rearing of southern Brazilian flounder supports the feasibility of flounder culture. Further research will improve weaning and grow-out techniques for the species.
