fish stress management...

Fish and shellfish are uniquely vulnerable to stress whether during transport, handling or manipulations such as vaccination, tagging or toxic water conditions. Pro-Tex™ has been shown to improve survival and enhance viability in a wide range of fish species and is used by major producers in the salmon, trout and tilapia industries as well as persons involved in aquarium fish transport.

It is of a considerable value in reducing the effects of stress in fish and shellfish allowing them to recover rapidly following exposure to stressful conditions.
