摘要：

The possibility that efficiency of feeding on different prey in three‐spined sticklebacks (Gasterosteus aculeatus L.) increases by experience of such items was investigated experimentally by comparing sticklebacks reared with only non‐moving prey (frozen brine shrimps) with sticklebacks caught in the wild from localities where a wide range of prey species was available. Fish without experience of natural food scored less well than those from the wild on various components of foraging and so had reduced feeding efficiency. However, feeding efficiency in naive fish improved after just a few days of experience with natural prey. Such experience‐induced changes in foraging efficiency will alter the profitability of prey items for individual fish. Copyright © 1992, Wiley Blackwell. All rights reserved
