Sustainable potential analysis of Indian mackerel (rastrelliger kanagurta) resource in East Coast waters of Aceh Province

Abstract

Indian mackerel (Rastrelliger kanagurta) was among the most commonly caught fish in Aceh east coast waters. Sustainability of Indian mackerel (R. kanagurta) must be maintained because of its important role in improving the fisheries economy in Aceh Province. This research was conducted in east coast waters of Aceh Province from January 2019-to April 2019. Purposes of this research were to describe the general condition and to find out the sustainable management scenario of the Indian mackerel (R. kanagurta) fisheries in Aceh east coast waters Province. The method used was quantitative descriptive. Data collection was done by conducting interview and literature studies. The material used was on Aceh Province capture fisheries statistical data (2003–2017) obtained from Marine and Fisheries Office Aceh Province. Data were analyzed by applying surplus production and dynamic system modelling. Results indicated that utilization rate value (URy) of the fish stock was 69%. Hence the utilization status of the Indian mackerel (R. kanagurta) resource was moderate exploited. Based on biomass in 2017, the sustainable management scenario of the fish for the next eight years (2018-2025) would achieve the highest allocation of fishing effort equal to total allowable catch (TAC) as big as 163%. Therefore, implementation of fishing efforts equivalent to the TAC regarding the biomass sustainability can be maintained until year 2025.
