Environmental factors for holothuria scabra sea cucumber cultivation

Abstract

Sea cucumber cultivation is an alternative to anticipate the continuity of production due to overfishing. Maintenance environmental factors are important factors to consider in sea cucumber cultivation. A suitable location really supports the success of sea cucumber cultivation. This study aims to identify the main habitat and indicators in determining a suitable location for cultivation of Holothuria scabra. The study was located in the intertidal zone of the Watuar village seagrass ecosystem during May 2020 to October 2020. The results showed that the location of the Watuar village seagrass beds was suitable to be developed as a sea cucumber cultivation location with three main indicators, namely 35 cm depth (at low tide) and 195 cm (at the highest tide), the condition of the seagrass vegetation is moderate and is the natural habitat of H. scabra with the dominance of the seagrass Enhalus acoroides, Cymodocea rotundata, Cymodocea serrulata, Thalassia hemprecchii with moderate density and the bottom substrate is muddy sand with particle size 100 µm of 96.7%..
