| Abstract |
This discussion and presentation encompass published works on predation, food organisms of carnivorous plankton and pertinent dietary information included under different topics in the literature and related subjects t o better understand some of the mechanisms involved in the f ish larvae survival. The aim of this review is t o elucidate predation and related subjects to better understand some of the mechanisms involved in the fish larvae survival.Data are compiled on the feeding of main plankton predators; Medusae, Siphonophorae, Chondrophorae, Ctenophora, Chaetognatha, Copepoda, Euphausiidae, Amphipoda, Decapod Crustacea, Polychaeta, Cephalopoda, within the scope of the information published, together with personal unpublished data obtained along years of study.The information on the dietary characte ristics of most planktonic predators indicate that these carnivorous animals need to feed continuously to fulfill their requirements for protein intake, and their inability to store food reserves in their bodies, which is implied by their active feeding behavior. These voracious animals appear in large numbers in some years and areas, and this abundance affects the ecological balance of the environment, and subsequently the pupulations of animals of importance in the commercial fisheries. Published information on predatory plankton species i s compiled in tables. |
