Impact of live food on survival and growth of hatchery-reared sea trout (Salmo trutta trutta L.) parr in the wild

---

Survival rates and growth parameters of hatchery-reared sea trout (Salmo trutta trutta L.) fry were determined after
stocking in the wild. The larvae were hatchery-reared for 12 weeks in two groups: fry were fed either on live zooplankton and live chironomidae larvae (LFG), or fed a pellet diet (PFG). The survival rate and specific growth rates were higher in the LFG than in the PFG group. Most effective for hatchery-reared fish intended for stocking was the natural, live feed. The mean number of chironomid larvae found in the stomachs of fish that were initially captured in
the wild was significantly higher in the LFG than in the PFG group. The live diet supplied in the rearing period had a positive impact on the foraging skills of the sea trout fry and their survival in the wild after their release on 24 April 2010.
