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

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

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

Koi carp produced in the Department

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

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

Reproduction of burbot • Spontaneous spawning • Semi-artificial spawning • Artificial spawning

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

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

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