1. Production
2. Ranching
3. Farming
4. Enhancement & mitigation
5. Conservation
http://www.fao.org/fishery/topic/4350/en
Production
Intensive culture to produce biomass & protein
- Trout
- Catfish
Production
Long growing seasonsEfficient protein- catfish, rainbow trout
Ponds on MS Delta
Ponds on Snake River, ID
Ranching
Fish are prduced in hatchery & released in ocean to be harvested when return.
- Salmon
Enhancement & mitigation
Fish produced to enhance a population or mitigate for loss of habitat
Conservation
Fish produced to reestablish population

Subsistence fisheries
A fishery where the fish caught are shared and consumed directly by the families and kin of the fishers rather than being bought by intermediaries and sold at the next larger market. Pure subsistence fisheries are rare as part of the products are often sold or exchanged for other goods or services
Recreational fisheries
Harvesting fish for personal use, leisure, and challenge (e.g. as opposed to profit or research). Recreational fishing does not include sale, barter or trade of all or part of the catch.
Commercial fisheries
Fisheries undertaken for profit and with the objective to sell the harvest on the market, through auction halls, direct contracts, or other forms of trade.
