Abstract

Five types of methods were prepared for this experiment. Each method contained gonad of Diadema setosum to use as natural stimulants for seabass. Five types of methods were raw gonad, gonad in powder form, gonad solution, raw wet agar strips coated with gonad in powder form and raw agar strips immersed in gonad solution. The experiment was conducted on seabass of 7.6 cm of total length by using one fish per tank. Feeding responses were classified into: (1) No reaction: fish remains on station without moving. (2) Orientation: rapid movement of the head pointing at food. (3) Approach: fish swims quickly towards food/odour. (4) Capture: fish nibble at food. (5) Ingestion: fish eats food. However, no feeding response was observed in control tank. For three types of method without raw agar strips, it showed that raw gonad method was the best respond time among the three methods and for another two methods with raw agar strips, it showed that raw wet agar strips coated with gonad in powder form was the best respond time. The experiment is useful for determining the suitability gonad of sea urchin to use as fish attractants. The study revealed that gonad of Diadema setosum can be used as fish attractants.
