EU Craft Project

Objectives

The main objective of this project is to secure the production of Eurasian perch (Perca fluviatilis) juveniles (3-5 g) in order to sustain the development of European SMEs (6) which have funded in this new way of diversification (production of 10-15 g fillets for consumption markets corresponding to 100-150 g fish). Presently, the juveniles availability is very low and limited to the annual cycle of reproductive period which occurs in early spring. Moreover, the quality of supplied juveniles is very variable. Thus, to support the sustainable development of Eurasian perch production, a R&D project is proposed to help the setting of a hatchery – nursery activity that other SMEs wish to develop.
In order to respond to the demand, a first objective of this R&D project will focus on the optimisation of the broodstock management considering environmental, nutritional and population variables :

  • to obtain delayed (extension of the natural reproductive period) and out-of-season spawning,
  • to reduce breeders mortality during the spawning period
  • to improve the control of gametes and larval quality.

Summary

 At this level, a specific action will be conducted on the cryopreservation of Eurasian perch semen for artificial reproduction. This objective will require multifactorial and multidisciplinary studies. A second objective will consist to develop protocols for the production of juveniles populations with improved potentialities (females monosex, Perca fluviatilis x Perca flavescens hybrids, triploids). Finally, an economical study will be realised to define the cost of production of juveniles using different rearing systems (semi-intensive in ponds and intensive in tanks) and considering different socio-economic contexts.
