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

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
