Building a better shrimp nursery, part 3

Shrimp nursery systems offer significant potential for compensatory growth after juveniles are transferred to ponds for final grow-out. Nursery feed selection and their management are critical components of shrimp nursery systems.

Building a better shrimp nursery, part 2

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.

Stocking density affects super-intensive biofloc nursery shrimp production

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 aquaculture revisited

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.
