3. Scientific activity fish reproduction and larviculture fish biology and ecology fishery management in lakes, rivers and reservoirs evaluation of water natural resources water recreation

4. Fish reproduction Main species: Asp (Aspius aspius) Burbot (Lota lota) Pike (Esox lucius) Perch (Perca fluviatilis) Pikeperch (Stizostedion lucioperca) European catfish (Silurus glanis) coregonids

5. Fish reproduction Wild cyprinids: dace (Leuciscus leuciscus), ide (L. idus), chub (L. cephalus), vimba bream (Vimba vimba), common bream (Abramis brama), rudd (Scardinius erythrophthalmus), tench (Tinca tinca), ziege (Pelecus cultratus), barbel (Barbus barbus), nase (Chondrostoma nasus) Ornamental fishes: goldfish, koi carp, orfe, cichlids, fighting fish

6. Koi carp produced in the Department

7. Reproduction Influence of photo-thermal conditions of fish reproduction in captivity Application different spawning agents, i.e.: hCG, CPE, GnRHa Application different doses of spawning agents Reproduction during spawning season or out-off-season spawning

8. Reproduction of burbot (Lota lota) Relict of ace age Freshwater cousin of cod Coldwater Delicious meat and liver Potentially new specie for aquaculture

9. Reproduction of burbot Spontaneous spawning Semi-artificial spawning Artificial spawning

10. Reproduction of burbot – hormonally induced spawning All females ovulated High synchronization of spawning (4 – 6 days after injection) Fertilization by „dry method” Large amount of gametes

11. Reproduction of asp (Aspius aspius) Reproduction during spawning season Out-off-season spawning Hormonal stimulation (CPE, GnRHa) High quality of gametes High survival of spawners

12. Larviculture Main topics: Stocking densities First food PNR Feeding regimes Cannibalism New technologies (illuminated cages, mixed feeding, combined methods) Burbot larvae
