2.2 Husbandry practices (introduction)
Aquatic animals are subjected to a range of different husbandry routines and operations throughout their respective production stages. The stressors caused by these operations, while in many cases unavoidable, can also in many cases be reduced. Since stress can not only impact welfare but production and survivability, there are both economic and welfare related motivations for ensuring that the frequency and effects on a number of key management practices are minimised. Conversely, certain practices (particularly enrichment) can have a positive effect on welfare.
To start thinking about welfare in relation to specific husbandry practices, please watch the following video produced by Dr. Jackson Gross, the Cooperative Extension Aquaculture Specialist in the Department of Animal Science at UC Davis, California, USA. In this video he introduces some of the practical welfare issues raised in relation to fish farming and husbandry practices. Think about how these might apply, and which are most significant for the species and systems you are most familiar with.

The following sections draw on research into the optimization of husbandry practices, within the respective species of interest, which can help to achieve the aim of better welfare.
