White Shrimp Population Dynamic in Riau Province: The Effects of Intrinsic Growth Rate and Effort

Amron , A. Mahdiana, F.E.D. Haryono and P.H.T. Soedibya

Fisheries management at Indonesia during the time is relatively responsive to unsustainable management.
This caused by this management which is not yet considering population dynamic aspects, such as intrinsic
growth rate, catch ability of fishing gears and carrying capacity. The objectives of these researches are to
develop and decide of the intrinsic growth rate and catch effort effects to white shrimp population dynamic
at Riau Province. Modeling was conducted to growth and harvesting model with numerical simulation
technique. The result of numerical simulation represents that intrinsic growth rate of white shrimp is equal
0.88 tons/years and carrying capacity is equal 38,023.26 tons. Existence standard effort 54,447 trips/years
cause decreasing maximum population growth became 10,941 tons of population with growth rate 2,831.3
tons. The optimal and sustainable management of white shrimp fisheries at Riau Province must be consider
population dynamic aspects.
