海水温度随着空间与时间的变化而变化;而在鱼类对外界生活条件的适应性中,对海水温度的适应性最为敏感。鱼类在各个生活阶段对海水温度的要求,海水温度的空间分布及其分布型式与渔场位置、鱼群在渔场停留时间长短、洄游迟早、洄游路线变动、鱼群行动、鱼群栖息水层、垂直移动、限制垂直移动等因素有着密切的关系。海水温度的变化,与渔场移
The temperature of seawater changes with time and space. In adaptability of fish to living conditions, it is most sensitive to the adaptability of seawater temperature. The temperature of seawater in different stages of life, the spatial distribution of seawater temperature and its distribution pattern and the location of fishing grounds, the length of stay of fish in fishing grounds, migration sooner or later, changes in migration routes, fish movements, fish habitats, Vertical movement, vertical movement and other factors have a close relationship. Sea water temperature changes, and fisheries move
