Types of culture fisheries

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.
