    <dcterms:abstract xml:lang="eng">The behavioral and morphological correlates of differential capture success at first feeding of the cichlid fish Cichlasoma managuense were investigated. Capture efficiency with nauplii of Artemia salina was 69% compared with only 6% with Daphnia. These drastic differences are attributed largely to the different morphology and behavior of the prey that may have produced behavioral changes in the fish. Daphnia is more evasive and harder to handle than Artemia as reflected in the significantly higher number of missed capture attempts and in spit-outs, a measure of handling effort. Fish hunting Artemia had a high capture rate when they made many attempts. By contrast, fish hunting Daphnia were successful when they handled the prey persistently, made many spit outs and many attempts. Large behavioral variation was observed and may be the substrate for later food specialization. In contrast to previous studies, morphological variation in the predators and prey was kept low; no measured morphological trait of the predators explained a significant portion of the variation in capture rate. The behavioral differences among the predators in each group alone significantly explain the variation in capture rate. The developmental stage of the fish and the behavior of the prey need to be considered when comparing the capture efficiency between species.</dcterms:abstract>
