The spinner shark, Carcharhinus brevipinna (Müller and Henle, 1938) is common in coastal warm-temperate, subtropical, and tropical regions worldwide (Compagno 1984). It is found abun-dantly off northeastern Taiwan, representing an important species for the commercial shark fishery in this area. According to catch statistics from the Nanfangao fish market, the biggest landing port for the shark fishery in northeastern Taiwan, annual landing of this species is about 115 tons, and ranks 6th (6%) in weight among all shark species in the region. This species is caught mostly in Oct. to Apr. when waters are cooler in this region (Liu et al. 2001). To date, biological information on the spinner shark is limited. Clark and von Schmidt (1965) documented the reproductive biology of this species in the Northwest Atlantic. Branstetter (1982) described the key characters of species identification for C. brevipinna and C. limtatus. Age, growth, and reproduction estimates are avail-able for the northwestern Atlantic (Branstetter
