Advances in aquaculture hatchery technology

8. Microbial management for bacterial pathogen control in invertebrate aquaculture hatcheries

By: E.F. Goulden,L. Høj,M.R. Hall

In aquaculture production systems, the hatchery phase is the most challenging as larvae are prone to infections and disease from microbial agents causing mass mortalities. A holistic microbial management regime concept is developed with the hatchery managed as a set of compartments: (1) the water column (planktonic); (2) surfaces (biofilm); (3) the larvae themselves; and (4) feeds (live and formulated). Emphasis on the use of the microbial community as a whole to maintain larvae in high health with various prophylactic strategies is discussed. A range of treatment strategies are considered, including antibiotics, bacteriophage therapy, quorum sensing inhibition and microbial predation. Developing innovations and future trends in microbial management and biocontrol are outlined.

Advances in aquaculture hatchery technology

9. Palinurid lobster larval rearing for closed-cycle hatchery production

By: M.R. Hall,M. Kenway,M. Salmon,D. Francis,E.F. Goulden,L. Høj

Closed life-cycle breeding of aquaculture species is essential for sustainability. The primary bottleneck towards this goal is a robust commercial-scale hatchery technology. The larval phase of Palinurid lobsters is amongst the lengthiest of any marine invertebrates; hence a major leap forward in aquaculture hatchery technology is required for commercial-scale production. The main challenges for Palinurid hatchery technology development are outlined together including aspects of water quality and tank design. The larval biology of Palinurid lobsters is discussed as well as broodstock husbandry and spawning. A concise review of reported diseases is presented together with larval nutrition requirements and their relationship to final larval metamorphosis to juvenile.
