| 摘要: |
| 本文主要描述北部湾北部沿岸头足类的种类组成,资源分布和季节变化。本海区头足类共有18种,隶属于2目4科7属。在一周年调查中,拖捕到的头足类占渔获量的11.2%;其中8月份头足类的渔获量最高,估计此时头足类的资源量有1794吨,1月份最低,资源量仅有171吨。头足类各类群周年的渔获量以枪乌贼的比例最大,占69.6%;乌贼占30.1%;章鱼仅占0.3%。枪乌贼的繁殖期6~10月份。调查结果表明,头足类资源是北部湾北部沿岸渔业资源的一个重要组成部分,有很大的经济价值。 |

| Abstract: |
| This paper deals mainly with the composition of Cephalopod species,its resources distribution and season variety along the northern coats of Beibu Gulf.There are 18 Cephalopod species in this area which belongs to 7 genera,4 families and 2 orders.In the investigation of one year,the quantity of the Cephalopod accounts for 11.2% of the total fishery harvest(including fishes).It peaks the annual catching in August.It is estimate that the resources of Cephalopod is about 1794 tons at this time but it only reaches 171 tons in January,the lowest month.The Loligo takes the largest propotion of the whole annual catching of Cephalopod,which takes about 69.6%,the sepia takes about 30.1% and the Octopus takes merely about 0.3%, The breeding period of Loligo is from June to October The result of investigation shows that the resources of Cephalopod is an important component part of the fishery resources along the northern coast of Beibu Gulf and its economic value is rather high. |
