Reserve site selection for data‐poor invertebrate fisheries using patch scale and dispersal dynamics: a case study of sea cucumber (Cucumaria frondosa)
ABSTRACT Globally, management decisions for recently established invertebrate fisheries are based on limited information. The negative consequences are being realized as now at least one‐third of invertebrate fisheries are over‐exploited, collapsed or closed. Management of a fishery should be based...

It is assumed that there is a positive relationship between spawner density and per capita population growth rate in sedentary broadcast spawners and that fertilization success declines rapidly at low densities. Protection of high‐density habitat would safeguard critical spawner density, especially when the critical density is unknown. Using spatial distribution, a method to identify size and location of reserves designed to protect high‐density habitat was developed.

The size of reserves can be set as 50% of each high‐density patch based on an appropriate risk‐averse approach. The allocation of reserve size and location is not dependent on results of a numerical circulation model.

ABSTRACT Globally, management decisions for recently established invertebrate fisheries are based on limited information.
