Other Marine Conservation Options

While many marine resource managers turn to implementing fish refuges for conservation and fisheries management, there are limits to the threats that fish refuges can adequately address. Many conservation and fishery management problems need other regulations and policies for effective protection, whether in parallel with fish refuges or as a better alternative to them.

​

Examples of other fishery management control options as outlined by McDonald (2018) are mentioned below. To better grasp how to put these controls in place, what target limits to set, what they protect, and their effectiveness in meeting socioeconomic objectives please visit McDonald AFAM Toolkit Guidance document (2018):

 

Catch limit. Sets an upper limit on how many fish can be removed by a fishery over a certain period of time. This can be for an entire fishery or can be allocated as catch shares to individuals or groups of individuals (such as a fisher association).

​

Bag/trip limit. Limits the number and/or weight of a species that an individual fisher or vessel can take in a single day.

Size limit. Sets minimum and/or maximum bounds on the size of the fish that can be legally caught.

Gear / Vessel Restrictions. Restricts the type, amount, or techniques allowed for a given type of fishing gear used by fishers in a particular fishery (including banning destructive fishing gear such as dynamite, cyanide, and fine mesh nets)

Deployment Limits. Places a cap on the number of gear each fisher can use (such as the number of hooks on a line or fixed traps).

​

Sex specific controls. Protect reproductively important individuals by setting sex-specific regulations on fishing activity.

Seasonal Closures. The banning of fishing activity during certain seasons to protect vulnerable life history stages.

Protection of ecologically important species. Restrict fishing of specific species to protect key ecological functions.
