Upwelling tank for culturing rock lobster (Jasus edwardsii) phyllosomas

Abstract

A tank system for culturing rock lobster (Jasus edwardsii) phyllosomas is described. Four tanks, one of which remains empty, are interconnected by ports that allow larvae to be transferred without handling and the vacated tank to be cleaned. Vertical water movement in each tank maintains the larvae in suspension, and the overall design and management allows for feeding with live brine shrimp (Artemia). Mean survival rates of over 60% to Stage VIII have been obtained, but only one puerulus has been reared.
