Fisheries Management Methods |
|
- The National Marine Fisheries Service and the Alaska Department of Fish & Game use many fishery management methods and techniques
- An important method is Total Allowable Catch (TAC) – set as a firm limit, beyond which fishing must stop
- Balancing finite fish stocks with improvements in catching efficiency must be regulated by:
- Time-and-area closures: These methods allow fishing during certain times or in certain
areas, but not in others
- Restrictions on size of boats: Certain fisheries have limits on the size of fishing boats
- Restrictions on type of fishing gear: Virtually every fishery has limitations on fishing
gear, such as the size, design, and use of each type of gear
- Gear prohibition: Certain gear types are completely prohibited, such as pelagic
longlines, sunken gillnets, and fish traps
- Alaska also limits the number of harvesters in a fishery through “license limitation” or “limited entry”
- Additionally, Alaska uses rationalization (also known as “rights-based” management), which
grants ownership rights to a given fraction of an annual Total Allowable Catch, and “inseason”
modification to adapt to the realities of the run, the weather, and other parameters
