The Behavior of Sea Cucumber <i>Phyllophorus </i>sp. during the Period of Adaptation
Keywords:Phyllophorus sp., behavior, sea cucumber, survival rate
Study on behavior of sea cucumber Phylloporus sp. is the first conducted in Indonesia. The fulfillment of local needs on sea cucumbers Phyllophorus sp were still depends mostly on the catch by local fisherman, so that the Efforts to improve the cultivation of sea cucumbers are important to examine that the cultivation of cucumbers can be started with the adaptation of sea cucumbers in advance. One of the factors influence the success of sea cucumber aquaculture is the success of its adaptation to a new habitat or environment. One of the adaptations required concerns with the depth of the water habitat of sea cucumber. The mud was needed as a substrate to immerse. This study aims to monitor the behavior of sea cucumber rates on varied depth of water and the survival rate of sea cucumbers in each depth. The method used is an experiment with completely randomized design as the experimental design. The treatments use different water depths, the which are 10, 20, 30 and 40 cm, and each treatment repeated 5 times with long maintenance for 30 days .. for how long time period? The behaviors of sea cucumbers during the study were Analyzed using descriptive and statistical analysis. The results Showed that normal behaviors of sea cucumbers occurred in order: fully exposed and fully half-buried body buried. The abnormal behaviors performed by sea cucumbers ranged from secreting intestine sequentially, then secreting the gonads and tentacles, and producing calcareous ring and slimy skin. The results of the survival rate of sea cucumbers show that the average survival period of sea cucumbers is not significantly different at the water treatment depth of 20, 30 and 40 cm.
