【 摘 要 】

ABSTRACT: Life-history theory predicts a tradeoff in resource allocation between early maturation and growth in species which exhibit indeterminate growth. However, since life-history models assume that the fitness payoff of each developmental strategy at completion is known, they are unable to encapsulate the mechanics by which maturation is controlled under natural conditions. To determine the proximate conditions which influence variation in reproductive investment, we recorded somatic growth, sexual maturation and fecundity in individually marked first-time maturing lesser sandeels
