?仔漁業漁場有三個,即東北、西北及西南水域,有11個漁會使用這三個漁場。本(2009)年春季東北水域投入366 d * set的努力量,生產42,999 Kg的?仔魚。平均每個可作業日有4.3組作業,可得114 Kg d-1的漁獲物。 西北水域投入1,553 d * set,生產125,458 Kg,平均日有16組作業,可得71 Kg d-1。西南水域投入1,346 d * set的努力量,生產297,008 Kg,平均每日有10組作業,可得229 Kg。
全海區主要漁獲物為刺公鯷及異葉公鯷,日本鯷幾乎沒有其蹤跡。宜蘭縣政府公告之TAC為600 t。由春漁期觀察潛在努力量之活性是32.6%於頭城地區及69.6%於蘇澳地區,而TAC之達成度為43 t,只有使用7.2 %的TAC。建議以334.9 t為合理化TAC之第一次建議值。 |

In NW, a bigger amount of 1,553 d * set was deployed to catch a size of 125,458 Kg in, 16 sets per day with a COUE of 71 Kg d-1.? In SW, fishermen used 1,346 d * setin spring to get 297,008 Kg catches.? In average, 10 sets were found in a day to obtain a cpue of 229 Kg d-1.
All fishing grounds as a whole, 95% of the stock was consisted of Engrasicolina punctifer and Encrasicholina heteroloba.? It is aberrant to normal year that Japanese did not appear in the fishing ground as part of major component.? Ilan county announced a TAC of 600 t in the NE fishing ground, and the TAC can be break into two parts of 450 t for TouChen FA and 150 t for SuAo FA.? Accordingly, the estimated activity for potential fishing effort is 32.6% for TouChen FA, and 69.6% for SuAo FA.? The realized TAC for Ilan County was 43 t, that is 7.2% of the TAC amount.? We proposed a value of 334.9 t for future revision of the NE TAC. |
