摘要: abstract:The trash fish generated by bottom trawling in surrounding waters of Guei-Shan Island, northeastern Taiwan was examined based on bi-weekly samplings from Mar. 2005 to Feb. 2006. The trash fish catch accounted for 20-25% of the total captured biomass in the region. In total, 215 bony fish species from 86 families were recorded. The juvenile fishes including large amount of commercial important species such as: ribbon fish, Scianeidae, lizardfishes and eels etc. accounted for more than 40% (in number) of this catch. The number of species, species richness and diversity for juvenile fishes were higher in the spring and fall, and lower in the summer and winter. Multivariate analyses have identified three juvenile assemblages corresponding to the mid-spring to early-summer, late-summer to mid-fall, and late-fall to early-spring seasons. High species diversity coincided with high biomass and abundance of juvenile fish catch in the spring and fall suggested that continue catch of these "trash fish" maybe detrimental for sustainable use of demersal fishery resources in the region, and such a situation should not be ignored. The management measures, such as mesh size limitation during the fall and spring may be necessary for the ecosystem to prevent a potential recruitment overfishing of commercial fish stocks in the region.
