“战略”和“战术”这两个术语都源于军事科学，在分析鱼类繁殖过程中很有用(Wootton，1984)。Wootton认为生殖策略是“一个物种中个体典型地表现出的繁殖的整体模式”；它由一系列特征组成，例如第一次繁殖的年龄、繁殖力和许多其他特征，包括配子的大小和性质(Wootton，1982,1984)。虽然战略和战术这两个术语的原意意味着理性的计划，但这一含义与生物过程无关。后者发生在多变的环境中；总体繁殖战略和战术变化都是适应性的。研究这种适应机制的一种方法是分析生殖策略特征与环境变量之间的关系。
The terms ‘strategy’ and ‘tactics’, both derived from military science, are useful in the analysis of fishreproductive processes(Wootton, 1984). Wootton considers reproductive strategy as a ‘overall pattern of reproduction typically shown by individuals in a species’; it consists of a complex of traits, e.g. age at first reproduction, fecundity and many others, including size and nature of gametes (Wootton, 1982, 1984). Although the original meaning of the terms strategy and tactics implied rational planning, this implication has no relevance to biological processes. The latter occur in variable environments; both the overall reproductive strategy and is tactical variations are adaptative. One approach to the study of such adaptive mechanisms is by analysing the relationships between traits of reproductive strategy and environmental variables.
