入海河口鱼类生物与水环境关系的研究现状与进展

RESEARCH AND PROGRESS OF RELATIONSHIP BETWEEN FISH AND AQUATIC ENVIRONMENTAL FACTORS IN ESTUARINE WATERS

入海河口区域作为许多鱼类的生活和繁殖场所,其环境变化对鱼类有着重要的影响。鱼类与水环境的研究对于河口环境及人类活动的评估有着重要作用,同时准确了解河口地区水环境与鱼类的关系,可以及时掌握环境状态及其变化,有利于进行科学的管理,以维持河口生态系统的稳定和渔业资源的可持续发展。本文综述了河口鱼类生物对水环境中温度、盐度、溶解氧等水环境因子的响应,并探讨了该领域的研究现状和未来的发展趋势,建议在水环境因子对鱼类生物量的影响以及多种水环境因子之间的联合作用等方面加强研究。

Estuarine areas are the places that fishes live and spawning in, and the changes of environmental factors in estuarine area have significant impacts on fish. The influence of estuarine environment on eggs and larvae can directly affect the fish survival and recruitment, and then affect the fishery resources abundance. The knowledge of relationship between water environmental factors and fishes are important to estimate the water quality and the impact of human activities. This paper reviews the estuarine fish＇s response to temperature, salinity, dissolved oxygen, and other factors of water environment, and review the influence of human activities on water environment and fishes. The development trend of this study was also discussed, and the scholars were suggested to pay attention on the relationship of environmental factors and fish biomass, and the cooperative effective of several environmental factors.
