Bioeconomic Analysis of the Giant Freshwater Prawns (Macrobrachium rosenbergii) Aquaculture in Fiji Islands

Abstract

This study aimed to analyse the bioeconomic effect of the giant freshwater prawn aquaculture production system in Fiji Islands. Based on data collected, feed conversion ratio, farm stocking density, feed consumption, revenue and expenses throughout the two annual culture pond cycles were calculated and annual net profit were estimated in order to determine the bioeconomic validity of giant freshwater prawn aquaculture production. Results showed that the giant freshwater prawn aquaculture production system had high profitability based on the current production and market conditions. This is because of its significant survival rate and good market price level. However sensitivity analysis of the main variables indicated that the profitability of giant freshwater prawn aquaculture is highly vulnerable to production conditions and market changes in Fiji Islands.
