Abstract

The purpose of this study is to know the densit, potential and the utilization of holothurians in Tatumbu Island. Data were collected at three stations by using Belt Transect. To identify the utilization of holothurians, the interview was done by using questionnaire. Environmental parameters were measured in situ including temperature, salinity and potential of hydrogen (pH). The results showed that there were nine commercial species and other three species found. The density of three stations ranged from 0,0012-0,0353 ind.m-2 and the potential was 17187 individuals. The highest density and potential were represented by Stichopus horrens whilst the lowest density was represented by Actinopyga echinites. Generally, holothurians distribution on sandy substrate associated with seagrass. The utilization of holothurians is conducted daily and continues by fishers. The temperature, salinity and pH indicated that the waters of Tatumbu Island were suitable for sea cucumber growth.

Abstract

Seagrass acts as a food source in supporting the productivity of the living creatures that lives sorrounds, rearing areas, and sediment filtering systems. The Village of Porto is one of the coastal villages that has a fairly extensive seagrass ecosystem. Seagrass, locally known as "lalamong" is located quite far from residential areas, but information about the condition of the seagrass is still lacking. So, this study aims to inventory the species of seagrass found there, analyze the density and attendance frequency and assess environmental parameters for seagrass growth. The research was conducted from January to March 2019. Seagrass data was collected using the linear quadratic transect method at the five stations and each station consisted of three transects. The results showed that seagrass beds in the research area consists of eight species of seagrass, namely Enhalus acoroides, Thalassia hemprichi, Halophila ovalis, Cymodocea rotundata, Cymodocea serrulata, Halodule uninervis, Halodule pinifolia and Syringodium isoetifolium. C. serrulata is the species with the highest density number, but the highest attendance frequency is represented by E. acoroides. S. isoetifolium is the species with the lowest density and attendance frequency. Station three has the highest seagrass density but has a low on attendance frequency. Water quality parameters (temperature and salinity) are suitable for seagrass in the coastal waters of Porto village.
