The biology and ecology of the blacklip abalone with reference to the juvenile stage between post-planktonic settlement and recruitment to the fishery

Project number: 1982-043
Project Status:
Completed
Budget expenditure: $0.00
Organisation: University of Tasmania (UTAS)
Project start/end date: 28 Jul 1984 - 30 Jul 1984

TAGS
Resource Enhancement
Reproduction
Population Dynamics
Nutrition
Life History

Objectives

1. Investigate biology and ecology of naturally spawned abalone
dynamics of hatchery abalone seeded into habitat vs. naturally recruited abalone
2. habitat requirements of juvenile abalone (to assess possible of bottom modification)
3. establish dietary requirements of juveniles.

Objectives

1. Estimate abundance & production of krill (especially Nyctiphanes australis) in an area of sth-east Tas coastal waters.
2. Study growth & moulting of N. australis to provide data for production estimates.
3. Identify the major predators & estimate their consumption

Summary

This final report on the project describes data on stomach contents of major fish predators of the euphausiid Nyctiphanes australis.

The study has concluded that: size and stock of krill and its production can be calculated with some degree of confidence; major predators of adult krill can be identified though the greatest mortality, which occurs in the larval stages, is probably due to carnivorous zooplankters; and swarming by krill is of extreme importance in increasing the attraction of krill as food.
