Abstract
    Since 1987 Frish Pty Ltd has been investigating techniques for extensive culture of zooplankton in large eutrophic impoundments in south-eastern Tasmania, Australia. The project is linking issues of production and quality directly to issues of environment. The objectives are to integrate zooplankton culture with the nutrient source associated with sewage waste to demonstrate the potential of nutrient recycling using this technique, to provide small copepods as the first food for marine fish larvae, and to provide larger zooplankton as food for post-larvae and fingerlings. The technique used is referred to as the Baleen method. There are three production stages and the object of each stage is to provide an inoculation of the selected zooplankton organism equivalent to 10% of the target biomass for the next culture stage. Zooplankton is harvested from the grow-out ponds using a Baleen zooplankton harvester. The results to date indicate that this technique has the potential to provide an economically efficient method of supplying live food for aquaculture hatchery and nursery operations. It has also demonstrated the potential to link the environmental objective of reducing nutrient pollution in waterways to generation of industrial benefits to the aquaculture industry .
