摘要
本文对长江口及其邻近海域大银鱼的繁殖、食性、生长、分布与洄游作了初步研究。长江河口大银鱼分布于盐度为0.01—30‰的水域。繁殖时期洄游到河口的淡水至12‰左右的咸淡水水域中产卵。大银鱼是在河口淡水和沿岸低盐度海水中繁殖的河口鱼类。湖泊中的大银鱼是被陆封在湖泊中的。
The paper presents a study of reproduction, feeding, growth, distribution and migration of Protosalanx hyalocranius(Abbott). The fish widely distribute in the Yangtze River Estuary and nearby brackish waters with salinity of 0.01-30‰. During the reproduction period, the fish migrate from high salinity waters to low salinity waters of the estuary to spawn. The salinity variation of spawning areas is about 0.0l-12‰ The average number of the vertebra of the fish found in Yangtze River Estuary is higher than that of the fish in the enchosed water of Taihu Lake.
