Effect of Codend Design and Mesh Size on the Size Selectivity and Exploitation Pattern of Three Commercial Fish in Stow Net Fishery of the Yellow Sea, China

To address the issue of minimum mesh size regulations stow net fishery for croaker species, we tested and compared selectivity exploitation pattern diamond- square-mesh codends with sizes 35, 45 55 mm little yellow (Larimichthys polyactis), silver (Pennahia argentata), flower (Nibea albiflora) in Yellow Sea, China. Our results showed that legal codend (35 diamond-mesh) was inadequate to protect juvenile species because more than 75% undersized individuals were retained, discard ratios as high approximately 60%. Irrespective shape, increasing could significantly improve species. Between same size, had higher diamond-mesh codends. Based on results, recommended rational stocks. This study can provide feasibility insight enforcement reform management strategies sustainable fishing Chinese fisheries.
