Development of Eco-friendly Aquaculture Design for Lobster Cultivation in Indonesia

Abstract

Lobster products are important for the economy in fishing community. Climate change will lead a threat to lobster productivity. Therefore, a solution offered is to cultivate certain lobsters, especially those with high economic value by using Aquaculture. This research aims to develop a small-scale aquaculture for the cultivation of lobsters with bamboo as primary material, which is environmentally friendly and inexpensive. The proposed design of lobster aquaculture in this research adapt lobster habitat in its nature. Therefore, it uses the artificial reef as a shelter for lobster. The main structure of the lobster cage uses bamboo and the floater use HDPE (High-density polyethylene) barrels. The result of aquaculture motion analysis using numerical model has been validated by experimental test in Flume Tank. The differences result of heave RAO (Response Amplitude Operator) motion between numerical model and experimental test is 0.05 m. The results of this validation analysis show that it is reasonable agreement.
