Abstract

Global fish stock has been significantly declined over the past 3 decades, especially in coastal waters. Over-exploitation of fish resources and habitat destruction has been considered playing important role in declining the fish stock. This study was conducted to restore sea cucumbers stock in Pulau Seribu. A base line study was needed to evaluate the status of seagrass ecosystems in restocking locations. The results showed there were 8 seagrass species identified in both study sites, covering 0-65% area, consisted of 20.45 ± 11.28% in Pulau Pramuka and 6.00 ± 6.56% in Pulau Kelapa Dua, respectively. Seagrass ecosystem in Pulau Pramuka indicated better condition than that in Pulau Kelapa Dua and statistically was significantly different (global R = 0.193; p < 0.001). However, to support the restocking efforts of sea cucumbers, the seagrass habitat in both locations need to be restored.

Abstract

Today, eel resource especially seeds in Indonesia has not been used for eel culture activities. To be able to optimally utilize the seeds that led to the production of eels for consumption needs adequate cultivation technology. This study aimed to obtain performance information of survival rate, growth rate, and feed conversion ratio to support mass production of eel consumption. The experiments were performed using aquarium of (0.8 x 0.4 x 0.4) m3 and concrete tank (1.7 x 1.7 x 1) m3with circulating water. Eel used were elver (1.2-1.5 g) and fingerlings (15-17 g). Silk worms (Tubifex) and artificial feed in the pasta form were used as feed. The results showed that the elver reared in aquarium or concrete tank with water recirculation system showed high survival rate of 78-79% and 86-96%, respectively. The specific growth rate (SGR) was good (0.6-0.8%), but the feed conversion was still high (33-21) for the elver fed with silk worms and very good (0.6-0.7) for elver fed with artificial feed. The juvenile eel reared in a concrete tank showed SR up to 85-94%, the SGR ranged from 0.8 to 1.2%, and feed conversion from 0.61 to 0.69. It can be concluded that the rearing of seed eel can be done incontainer using water recirculation system with stocking density of 3 individuals/land 1.5 kg/m3in preparing the seed to be ready tobe cultivated outdoors.
