摘  要:
方氏云为近岸季节集群性小型底层冷水性鱼类,黄、渤两海均有分布。黄海北部及渤海主要群体每年10~11月集中在北纬38°00′~39°00′近岸水域产卵,群体中Ⅳ个世代,雌雄性成熟均为Ⅱ龄。方氏云在辽宁沿岸每年有两次渔汛期:幼鱼渔汛期3~5月,渔获量3×106~4×106kg;成鱼渔汛期9~12月,渔获量约2×107kg。渔业产值近亿元。目前方氏云成鱼在辽宁的资源量约6×107kg,年捕捞量约3×107kg,现阶段资源量与捕捞量基本平衡。

摘  要:
Fang's blenny Enedrias fangi Wang et Wang is a small,seasonal grouping and cold species and found in offshore bottom of Yellow sea as well as Bohai sea.The fish spawns in Northern Yellow sea and Bohai sea(N38°00′~39°00′) in October and November.Five generations were found in the population and its age at maturity is 2 years old.There are two fishing seasons in Liaoning coast: one is juvenile season in March to May with approximate production of 3~4×10~6 kg, and the other is adult one in September to December with 2×10~7 kg production.Total values reach about 100 million RMB each year.It is estimated that the fishery resource is about 6×10~7 kg in coastal Liaoning,and fishing production about 3×10~7 kg annually,basically equivalent between resources and fishing production at present.
