Abstract :
A prawn larvae/Juvenile separation mechanism was developed using funnel-shaped larvae valves. Several characteristics of larvae and juveniles were utilized in the design of the equipment: (1) the larvae are active swimmers while the juveniles adopt a benthic mode of life and (2) the larvae are attracted by light. Tests showed that better than 95 percent efficiency in separation can be achieved. Based on the results, a complete pilot hatchery system for prawn juvenile production is being designed.
