The 1987-1995 length composition of quarterly catches of Scomberomorus commerson (Lacepede 1800) was analyzed to determine various biological reference points for management purposes. These include: fishing mortality producing maximum yield-per-recruit in weight (F sub max), fishing mortality producing 50 percent relative mean mature biomass (F sub 50), and fishing mortality producing recruits that would exactly replace their parent stock (F sub rep). F sub max provided misleading suggestions to increase fishing mortality on the stock which is currently at a low level. On the other hand, both F sub 50 and F sub rep provided acceptable results, suggesting reduction of the current fishing mortality by 17-40 percent
