Evolutionary and ecological constraints of fish spawning habitats


For marine fishes, the location of the spawning habitat may be the only means to compromise between the need of successfully developing from an egg into a juvenile and that of dispersing across different habitats while minimizing predation and maximizing food intake. In this article we review the factors that affect the choice of fish spawning habitats and propose a framework to distinguish between ecological and evolutionary constraints. Ecological constraints, driven by the animal surroundings, limit the ability of a species to change its spawning habitat without incurring genetic adaptation. Their strength is modulated by mortality due to aberrant dispersal, starvation and predation of fish early life history stages. Species can genetically adapt to local environmental conditions to overcome these factors. However, evolutionary constraints, driven by the animal's evolutionary history, limit the ability of a species to genetically adapt. Their strength is related to traits that have low diversity within a taxon, such as pelagic larval duration, reproductive biology and the population social structure. We argue that fisheries oceanographers are well aware and more deeply focused on the former set of constraints, while evolutionary biologists are more deeply focused on the latter set of constraints. Our proposed framework merges these two viewpoints and provides new insight to study fish habitat selection and adaptability to future environmental changes.
