EEZ HIGH SEAS

Sedentary stocks will no movement and no mixing. Resource may befixed (coral) or buried (clams). Each compartment may be managedseparately but depletion of spawners in one compartment may affect theother.

EEZ HIGH SEAS

Low diffusion stock, little movement and little mixing. Stock componentscould be managed separately with little error. Depletion of spawning stockin one compartment may affect reproduction of the other.

EEZ HIGH SEAS

High diffusion stock, Extensive random, Movement and important mixing.Stock should be managed as one unit. Management of one of thecomponents will directly affect the other.

Juveniles Adults

Inshore Off-shore

Inshore-offshore on together migrations. The stock should be managedas single unit. Specific measures (mesh size limit, effort control) may bearea-specific. Age-specific fisheries should be managed as sequentialfisheries (artisanal fishery, commercial fishery, foreign fleets.)

How to Manage Trans-boundaryFish Stocks?

Joint research program on trans-boundary fishstock.

Establish a management body (Regional

Fisheries Management Organization: RFMO forstraddling stocks and highly migratory stocks)

Set up total allowable catch.

Establish management programs bymanagement body.
