Feeding Artemia and shellfish to phyllosoma larvae of southern rock lobster (Jasus edwardsii)
Newly-hatched phyllosoma larvae from southern rock lobster (Jasus edwardsii) were grown in culture vessels containing 10 l sea water in a flow-through system at 18 degrees C and fed diets of Artemia sp. and shellfish. The survival and growth of larvae to Stage II was higher when fed ongrown (1.5 mm...
