Fishfarm Kreuzstein
Production of local strains of the
following species
Coregonus spp. (coregonids)
Salmo trutta (lake trout & brown trout)
Salvelinus umbla (Arctic charr)
Hucho hucho (Danube salmon)
Thymallus thymallus (grayling)
Abramis brama (freshwater bream)
Barbus barbus (barbel)
Chalcalburnus chalcoides (bleak)
Chondrostoma nasus (nase)
Leuciscus souffia
Phoxinus phoxinus (minnow)
Rutilus meidingerii
Vimba vimba (Vimba bream)
Production of brood stock material
from local autochthonous populations
Hatching of eggs
First feeding of larvae
Lota lota (burbot )
Esox lucius (pike)
Cottus gobio (bullhead)
On-growing of juveniles to fingerling size
Distribution of fingerlings
Restocking
Aquaculture
Assessment of ecological status of Austrian
lakes and running waters under WFD
Weaning of fingerlings and distribution
to specific fish farms
Definition of deficit species
Advantages for fish farms:
Local strains for specific local products
Development and implementation of
strategies for improvement of water
systems
Restocking of the specific water
systems with genetically conform fish
Fish adapted to the specific local
situation show :
 Better survival
 Better performance
 Higher reproductive success
 Increased disease resistance
