The Taiwanese Bua Fishery is artisan practices using small-mesh fishing gear at coastal area of 500 m with a depth less than 30 m. This fishery utilizes larval and juvenile fishes, and thus is generally considered unreasonable utilization on the resource. However, this traditional practice was profitable, and in the mean while is favorable to the local public.
Stringent management applied to the fishery was started in 2001. The management plan highlighted regulation on total vessel number, allowable catches and closing season in addition to a maximum fishing period of five years. In order to mitigate the impact of total phasing-out in 2006, the agency implemented a measure of designated fishing halt plan by gradual expansion of banning season. This study is aiming at evaluating the effectiveness of the fishing halt.
After compiling 16-years historical data, we found that the effectiveness should be 2.02% when only June is banned. However, if the banning season (June-August) is strictly enforced, the effectiveness should go to 22.2%. If April, May and September are accepted as designated fishing halt, 51.4% of the resource amount should be saved. Ten fish species can be significantly benefited from the designated fishing halt; i.e., Leiognathus lineolatus, Secutor ruconius, Saurida wanieso, Sillago japonica, Sillago sihama, Gerres abbreviatus, Trachinocephalus myops, Harpadon nehereus, Liza affinis and Enneapterygius etheostomus. |
