There were lesser and fewer in commercial species and its numbers in the cover net, and the sum of Nemipterus virgatus , Saurida tumbil , Upeneus bensasi , Trachinocephalus myops comprised 95.4% in number and 86.0% in weight of sample catch in the cover net,respectively. The high percentage of juvenile commercial species that were undersized in the codend showed 30.3 mm square mesh codend had more serious damage to most juvenile commercial species, approaching or exceeding 50% in percentage of juvenile species which body length is smaller than fishable size- Trichiurus haumela, Priacanthus tayenus , Navodon tessellatus, Argyrosomus argentatus, Nemipterus bathybius and so on, even exceeding 90% in percentage of juvenile Sepia spp, Loligo spp and Parastromateus niger. In particular, 50% selection lengths ( L 0.5) caught Saurida tumbil and Nemipterus virgatus were smaller than their minimum fishable size.
