摘要:

］分析了2006—2007年福建闽江口及附近海域和厦门沿岸海域4个航次的底拖网渔获物中软骨鱼类的种类组成、数量、资源密度及其季节变化.结果表明：4个航次捕获软骨鱼类17种，隶属于5目9科9属，其中鲼形目最多，有9种.在闽江口及附近海域，捕获软骨鱼类12种，优势种类有尖嘴和光，春、夏、秋、冬4个航次分别捕获软骨鱼类5、9、11、6种；捕获的软骨鱼类占该海域鱼类总渔获量的12.31 %；平均资源密度和平均栖息密度分别为90.92 kg/km2和210.56 ind/km2，其中夏季最高（平均资源密度和平均栖息密度分别为204.02 kg/km2和403.14 ind/km2）；奈氏的资源密度最大，而尖嘴的栖息密度最大.在厦门沿岸海域，捕获软骨鱼类12种，优势种类有条纹斑竹鲨、尖头斜齿鲨和小眼，春、夏、秋、冬4个航次分别捕获软骨鱼类5、8、7、5种；捕获软骨鱼类占该海域鱼类总渔获量的30.18%；平均资源密度和平均栖息密度分别为122.56 kg/km2和592.78 ind/km2；平均资源密度冬季最高（173.13 kg/km2），栖息密度则以秋季最高（1 169.06 ind/km2）；条纹斑竹鲨的资源密度和栖息密度均大于其他软骨鱼类

Abstract:

Based on the data of bottom trawl surveys in Minjiang estuary and its neighboring waters and Xiamen coastal waters during 2006 and 2007,the species composition，quantity，resource density and the seasonal variation of cartilaginous fishes were analyzed.The results showed that there were 17 species of cartilaginous fishes belonging to 5 orders,9 families and 9 genus,and Myliobatiformes was the dominant orders,which accounted for 9 species.In Minjiang estuary and its neighboring waters,there were 12 species of cartilaginous fishes,whose dominant species were Dasyatis zugei and Dasyatis laevigatus;spring,summer,autumn and winter voyages caught 5,9,11 and 6 species of cartilaginous fishes respectively;the percentage of weights of cartilaginous fishes caught in all the four voyages accounted for 12.31 % of total fishes;the average resource density and habitat density accounted for 90.92 kg/km2 and 210.56 ind/km2 respectively;the average resource density and average habitat density were highest in summer, which were 204.02 kg/km2 and 403.14 ind/km2 respectively,and the resource density of Dasyatis navarrae was the highest while the habitat density of Dasyatis zugei was the highest in 4 voyages.In Xiamen coastal waters, there were 12 species of cartilaginous fishes too,of which Chiloscyllium plagiosum,Scoliodon sorrakowah and Dasyatis microphthalmus were preponderant species;5,8,7 and 5 species of cartilaginous fishes were caught in spring,summer,autumn and winter voyages respectively;the percentage of weights of cartilaginous fishes caught in all the four voyages accounted for 30.18 % of total fishes weights;the average resource density and habitat density accounted for 122.56 kg/km2 and 592.78 ind/km2 respectively;the average resource density was highest in spring voyage,which was 173.13 kg/km2,but the average habitat density was highest in autumn voyage,which was 1 169.06 ind/km2;and the resource density and the habitat density of Chiloscyllium plagiosum was highest in 4 voyages
