A study on stocks of trap s fishes in Abumusa Island
This report is about coral-reefs around Abumosa lsland from January 1998 till February 1999 by trap and underwater visual census. Total species belonging to genus and family were idemtified and length-weight relationship were estimated for more frequent species. Small tooth emperor (Lethrinus microdon) was predominate from other species. Catch per unit of effort (CPUE) calculated for each trap (large, medium and small). Efforts were based on number of trap and day. Cupue of small and large traps was further in late summer compare other seasons. Results of catch analysis showed that no differ catch value (eatable, fishes, ornamental fishes and total catch) between small-medium and medium-large traps. Value catch wasn t significant difference between three depth (0-10, 10-20 and 20-30m) and four geographical side, too. But, catch value of ornamental fishes was significant difference between depths 0-10 and 20-30 meter.
