【摘要】 报道了1994 ~1995 年对中国沿岸小型鲸类误捕情况的调查结果.调查表明,有误捕记录的小型鲸类主要有5 种,即江豚( Neophocaena phocaenoides) 、长喙真海豚( Delphinus capensis) 、瓶鼻海豚( Tursiopstruncatus) 、点斑原海豚(Stenella attenuata) 和伪虎鲸( Pseudorca crassidens) ,其中以江豚的误捕率最高.1994 年在山东、浙江、福建、广东、海南省和广西壮族自治区沿岸渔业误捕的小型鲸类约3045 ±2120 头,其中江豚的误捕量约2132 ±1484 头.误捕小型鲸类的渔具主要有拖网、刺网和张网.中国沿岸没有专门捕鲸的渔业方式.误捕的小型鲸类在沿岸居民的生活中不占重要地位,它们大部分被丢弃或廉价出售.目前尚不知道误捕对中国水域小型鲸种群影响的程度,但可能是造成数量下降原因之一.

【Abstract】 This paper provided the results of the survey on the incidental catches of small cetaceans in coastal waters of China, which was conducted in 1994~1995. Finless porpoise ( Neophocaena phocaenoides ) was captured most frequently in the Chinese coastal fisheries, while other small cetaceans, including long beaked common dolphin ( Delphinus capensis ), bottlenose dolphin ( Tursiops truncatus ), pantropical spotted dolphin ( Stenella attenuata ), and false killer whale ( Pseudorca crassidens ), were caught incidentally. In 1994, the annual incidental catches of small cetaceans in coastal waters of Zhejiang, Fujian, Guangdong, Hainan and Guangxi were about 3045±2120 individuals, whereas those of finless porpoise were about 2132±1484. The gears for incidental catches were predominantly trawl nets, gillnets, and stow nets. No direct catches of small cetaceans existed in China. The incidentally captured small cetaceans did not occupy an important place in the daily life of people in coastal China, and they were discarded in the sea or sold at a very low price in fish markets. The exact impact of incidental catches on small cetaceans in Chinese waters was not clear at present, but it has probably caused the decline of their populations.
