It is often necessary to transport fish as part of an animals production cycle. Transport distances vary from small tank-tank transfers to much longer hatchery-growout transfers or tank-market transfers. The level of stress during transport is one of the biggest factors in the success of a specific transfer. AQUI-S® can be used to limit stress before and during transport.
Types of Transport
There are five main techniques for transporting live fish:
- Insulated tanks or sealed plastic bags in boxes - by air
- Tanker trucks - by road
- Well boats - by river/sea
- Towing of cages by tugs
- Helicopter transport to remote locations
Fish require a life support system during the transport event – water must be oxygenated, accumulation of toxic metabolites such as carbon dioxide and ammonia must be controlled, and water temperature must be maintained within the appropriate range. Stress from crowding, handling and loading before transport evokes the physiological stress response resulting in increased oxygen consumption, carbon dioxide excretion and waste production. This, in turn, can rapidly lower the water quality, perpetuating a further, more stressful environment. The prolonged effects of stress before and during transport include high mortalities, reduced resistance to disease and poor growth performance.
