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. 

Shrimp nursery systems offer an important opportunity to increase profits. Properly designed and operated nurseries are highly biosecure facilities to grow postlarvae at very high densities. 

While sea cucumbers are one of the most prized seafoods in China and Asia, their production suffers from suboptimal juvenile production. The use of proper feeds and overall management in the nursery can improve yield and survival. 

The authors performed a study to determine the tolerance of shrimp postlarvae to the crowding effects of high-density stocking in terms of production performance. Postlarvae were stocked in heavily aerated microcosm tanks with biofloc at 1,500; 3,000; 6,000 or 9,000 shrimp/m3. High survival was observed at all densities. Final biomass values increased with higher stocking densities, but there was no significant difference between the 6,000 and 9,000 shrimp/m3 treatments or the 1,500 and 3,000 shrimp/m3 treatments. 

Mahimahi is a fast-growing, high-value fish species with excellent potential for aquaculture. The technology for maturation, spawning, larval rearing, fingerling production has been mastered, yet progress toward commercial development has been slow. 

For an intensive shrimp nursery, the main goal in feeding is to supply each animal the proper quantity of feed where it can be easily accessed and consumed. 

Intensive nursery systems are an extension of hatcheries to acclimate postlarvae to farm conditions and assess quality and health prior to pond stocking. 

Researchers at the Gondol Research Institute for Mariculture in Indonesia have studied the artificial propagation of groupers since 1995. In 2001, GRIM began successfully producing grouper seedstock at commercial-scale levels.
