| 摘 要： | 为摸清中国黄海秋季头足类的资源状况,本研究根据2006–2013年秋季黄海渔业资源调查所取得的292个站位底拖网资料,以渔获率作为头足类资源分布的数量指标,分析黄海秋季头足类的种类组成、数量分布、年度变化以及空间分布格局。结果表明,黄海秋季分布的头足类有14种,隶属于3目6科8属,不同年度头足类的种类变化为(8±2)种/年,以温带种占优势,也有一定数量的暖水种,未出现冷水种,明显反映出暖温带海区的动物区系特征。黄海秋季头足类的优势种为太平洋褶柔鱼(Todarodes pacificus)、日本枪乌贼(Loligo japonica)、剑尖枪乌贼(L.edulis)、针乌贼(Sepia andreana)和双喙耳乌贼(Sepioda birostrata),年际间优势种稍有不同。更重要的是,此阶段调查捕获了3个黄海新记录种:罗氏乌贼(Sepia robsoni)、多钩钩腕乌贼(Abralia multihamata)和真蛸(Octopus vulgaris)。根据这3个暖水种在黄海其出现的位置、频率和数量,分析可能的原因是全球气候变暖使得头足类暖水种分布的纬度发生变化,导致其栖息范围扩大。调查还发现,柔鱼类和枪乌贼类为秋季黄海头足类优势类群,不同类群头足类的渔获量在年际间存在一定波动,且过去的十多年间黄海秋季头足类资源组成结构已有所变化。黄海不同区域间头足类资源量从北往南呈现递增趋势,黄海北部、中部、南部头足类的平均渔获率分别为0.55 kg/h、0.67 kg/h、0.98 kg/h。本研究结果可为黄海头足类资源养护和可持续利用提供理论依据。

| Abstract: | An 8-year survey was conducted from 2006 to 2013 at 292 base stations using a bottom trawl to describe the autumnal distribution of cephalopods in the Yellow Sea. The cephalopod catch rate was used as a core quanti-tative index to analyze species composition, quantitative distribution, inter-annual variability of dominant species, and the spatial distribution pattern in the Yellow Sea. Fourteen cephalopod species, belonging to three orders, six families, and eight genera, were captured during the survey. The number of species captured per year varied (mean, 8±2), and the fewest were captured in 2009. Most of the species were temperate, a number of warm water species were captured, but no cold water species were collected, reflecting the faunal characteristics of a warm temperate zone. The dominant species wereTodarodes pacificus,Loligo japonica,Loligo edulis, and Sepioda birostrata, although a slight difference existed between different years. Notably, three new species were recorded from the Yellow Sea during this investigation:Sepia robsoni,Abralia multihamata, andOctopus vulgaris. These species were probably present because their habitat ranges may have increased in latitude based on their location, fre-quency, and quantity. The survey also found that squid and cuttlefish were dominant cephalopods during autumn in the Yellow Sea. The annual catch of different groups of cephalopods fluctuated, and the resource composition structure has changed in the past 10 years. The quantities of cephalopod resources in different regions of the Yel-low Sea showed an increasing trend from north to south. Average catch rates in the northern, central, and southern parts of the Yellow Sea were 0.55 kg/h, 0.67 kg/h, and 0.98 kg/h, respectively. These results will provide a theo-retical basis for conservation and sustainable utilization of Yellow Sea cephalopod populations. |
