Maryland; Atsushi Hagiwara, Japan; Gidon Minkoff, British
Columbia; Amos Tandler, Israel; Karen Pittman, University of

representatives from live feed and enrichment product suppliers.
Focus:
1. review current status of live feed production in Atlantic Canada
with emphasis on improving successful production of juvenile marine
fish for commercial scale on-growing
2. open discussion among participants of problems and areas for
improvement
3. develop plans for collaborative projects to help solve problems and
refine techniques
Topics (to include but not be limited to):
Latest developments in Artemia and rotifer enrichment
Spray dried heterotrophic algal products
Commercial lipid emulsions
Special fish roe phospholipid based emulsions
Cool temperature effects in enrichment
The role of algae in larval fish culture
Why do algal cultures crash
Which are the best species of algae and why
The fish larvae themselves
Larval nutritional requirements
Physiological changes during development
Metamorphosis and weaning
Feeding behavior and feeding strategies
Feed attractants
Prey behaviors to trigger feeding responses
Feeding densities and frequencies
Mass culture system for copepods to replace/supplement wild
zooplankton use
Both benthic and pelagic species may be considered, particularly
Tisbe sp. and harpacticoids
