Predation Mortality of Fish Larvae: Peril of the Unfit or the Unfortunate?

9521240 Fuiman鱼类种群丰度的波动是影响生命早期阶段生存的生物和环境因素造成的。捕食造成的死亡率是年类大小的一个主要调节因素，它与幼虫生长速度的相互作用以及幼虫易受捕食者攻击的时间可能是海洋中最常起作用的机制。本研究的重点是对幼虫招募的另一种普遍接受的假设，即生长速度和先天适应度，而不是简单的大小，影响幼虫的生存潜力。行为学、模型和中观实验的数据将为理解捕食对幼虫向成虫种群补充的重要性提供基础。＊＊＊

9521240 Fuiman Fluctuations in the abundances of fish stocks result from biotic and environmental factors that affect the survival of early life stages. Mortality from predation is a major regulator of year-class size and its interaction with larval growth rate and the time at which larvae are vulnerabile to predators may be the mechanisms most often operating in the sea. This research focuses on an alternative to a generally accepted hypothesis for larval recruitment, specifically, that growth rate and innate fitness, lot simply size, influence survival potential of larvae. Data from ethological, modeling and mesocosm experiments will provide a basis for understanding the importance of predation on recruitment of larvae to adult stocks. ***
