Aspects of the reproduction and early life history of Ladigesocypris
ghigii a freshwater fish species endemic to Rhodes island (Greece): Implementation
In the course of a Life-Nature project aimed at implementing management
actions for the endangered freshwater fish Ladigesocypris ghigii, endemic
to Rhodes Island (Greece), primary data were collected on reproduction
and early life history. The results of artificial fertilisation and rearing
experiments are described. The reproductive period was determined from
gonadosomatic indices and recording the presence and abudance of larvae
in the field over a 13-month period. Breeding occurred in spring and early
summer; however, the exact onset and duration of the reproductive period
differed between areas and possibly years. Based on the large numbers
of larvae and juveniles found, L. ghigii does not seem to face any serious
recruitment bottleneck. Thus, extensive captive breeding and subsequent
stocking actions are not recommended as a conservation tool for this species.
