Effect of domestication on ide Leuciscus idus L. reproductive parameters
Abstract:Ide Leuciscus idus L. is a riverine cyprinid commonly produced as a subsidiary species in polyculture with common carp in Poland. In many cases production of restocking material is based on farm‐reared broodstock. The aim of the paper is to study possible domestication effects on female reproductive parameters in ide following long-term pond cultivation. Three groups of fish were analysed: group (1) consisted of fish cultivated in carp ponds for three generations; group (2) consisted of fish caught as wild one‐year‐olds in rivers and kept in ponds until till sexual maturation (first pond‐reared generation) and group (3) consisted of wild ide females caught at spawning sites just before natural spawning. All fish originated from the Vistula River in central Poland. Fish were stimulated with Hungarian synthetic hormone analogue (Ovopel). Body length and mass, individual fecundity and egg size were measured during spawning, and egg survival was assessed at the eyed ova stage.
