Tank enrichtment for juvenile salmonids to produce powerful and robust seedlings for aquaculture in Germany

Project


Project code: 2813MDT902, TI-FI-08-PID1606
Contract period: 01.10.2014 - 31.07.2017
Budget: 236,229 Euro
Purpose of research: Demonstration

Increased intensification in aquaculture production raised a strong public as well as scientific debate on animal welfare. Within the present pilot and demonstration project we intend to show how salmonid species can be produced in a seminatural way, resulting in improved welfare of these fishes. In cooperation with conventionally and organically producing local aquaculturists we want to show how salmonid fishes (rainbow trout, brown trout, brook trout and hybrids of brook trout x Arctic charr) can be produced in a seminatural way. Within the project, we will implement recent findigs on environmental enrichment, i.e. an increase in environmental complexity by addition of natural substrates to the housing environment, into aquaculture practice. In addition we intend to demonstrate the positive effects of water current and thus swimming during the rearing process of juvenile salmonids. We consult pilot aquaculture enterprises on environmental enrichment of the housing environment and assist them during implementation into commercial aquaculture practice.
