Effect of Different Stocking Densities on Growth and Survival Rates of Sea Cucumber Holothuria scabra Seedlings

The natural stock of sea cucumber Holothuria scabra (known as sandfish) has been declining in both population and size, making it difficult to collect broodstock and juvenile sandfishes for aquaculture. This research aims to evaluate the reproduction of domesticated broodstock (F-1) and performance of the juveniles (F-2). Broodstock were reared in two rectangular concrete tanks with a dimension of 190 x 290 x 70 cm3. There were 12 individuals (7 males and 5 females) of broodstock (F-1) with total length and mean body weight of 12.0 ± 1.21 cm and 122.6 ± 32.37 g, respectively. Six broodstock were put in each tank and fed with compressed benthos at 4% biomass daily in the afternoon. During our experiment, domesticated sandfish broodstock successfully spawned twice. The first spawning (occurred in January 2017) had one female spawned that released 1,350,000 eggs with a hatching rate of 57.4%. Another broodstock spawned in April 2017 and produced 3,280,000 eggs with a hatching rate of 78.66%. The growth performance of 170 days-old juveniles (F-2) shows a total length of 5.66 ± 0.90 cm and a mean body weight of 10.08 ± 2.07 g. The survival rates are 5.19% and 8.68% for juveniles spawned in January and April, respectively. We conclude by showing that sandfish could be domesticated to produce seeds for further aquaculture development.

Culture Growth

Sea cucumber Holothuria scabra has high market value and demand, consequently its stock has sharply declined due to overexploitation. Aquaculture of sea cucumbers is a key to conserve and to restore the decreasing population while producing them for commercial purpose. The obstacles in scale-up production are still need to be addressed in nursery stage, juvenile release techniques and grow out which can be implemented in pond culture. Growth performance of H. scabra juvenile cultured in floating hapas was investigated in pond in Sekotong, West Lombok. In 12 weeks of field trial, the effect of three different initial groups of juvenile: small (1.42 + 0.01 g ind-1), medium (3.42 + 0.02 g ind-1) and big (7.77 + 0.02 g ind-1) were tested on their growth and survival by Completely Randomized Design. The result showed both Specific Growth Rate and Weight Gain were higher in small group (2.57 + 0.11 ‰d-1 and 2.57 + 0.11 %, respectively). The highest survival rate was in the biggest initial size group. Pond in Sekotong, West Lombok is potential for nursery and grow out of H. scabra juvenile.

Sandfish (Holothurai scabra) and seaweed Gracilaria sp are marine commodities that have economic value and have good prospects in the market. These two commodities, if rearing together, will certainly provide added value to farmers. This research aims to determine the potential of sea cucumber polyculture, (H. scabra) and Gracilaria sp. which is maintained in culture. This research was conducted in April - May 2018 in the coastal of Rat village, Southeast Maluku Regency. Sea cucumbers are weighed and stocked on Pen-culture (measuring 4 x 3 meters) with a density of 40 individuals / Pen-culture. Gracilaria seeds are taken from young thallus which are tied into one clump and ditagging. After that, Gracilaria was weighed and spread in Pen-culture of 20 clump / Pen-culture. Observation of growth and survival of sandfish and Gracilaria sp done once a week. At the same time, predator control is carried out on pen-culture and water quality measurements. The results showed that sea cucumbers experienced absolute growth and survival rates of 18.20 g and 92.5% respectively. Gracilaria sp which is maintained does not experience growth, while the percentage of survival of Gracilaria sp is 20%. Based on the results of the research it can be concluded that Polyculture of sandfish, H. scaba and seaweed, Gracilria sp is not effective if Gracilria sp is stocked on the basis of Pen-culture.Keyword : Sandfish, Gracilaria, PolycultureABSTRAKTeripang pasir (Holothurai scabra) dan rumput laut Gracilaria sp merupakan komuditi laut yang bernilai ekonomis dan mempunyai prospek yang baik dipasaran.

Although sea cucumber Holothuria scabra has always been part of the traditional exploitation of the benthos of Mahout Bay in the Arabian Sea, the foreign demand for the product and its high price have put increased pressure on the resource leading rapidly to overfishing. Aquaculture of this species has developed as a response to the overfishing problem but has not been yet studied in Oman. As a first step to evaluate its potential for aquaculture in Oman it was thus necessary to conduct hatchery trials. Four hatchery trials were conducted to evaluate the quality of the local broodstock, the response and efficiency of in-vitro maturation and fertilization and the success of larval development and rearing. Collected animals of 200-600 g were transported by road for 5 hours with zero evisceration to the Hatchery station. In-vitro maturation and fertilization success of more than 90% were achieved using the maturation inducing fractions (MIF) method leading to the development of mature eggs and normal embryos larvae. Auricularia larval stages were completed within 15 days and fed normally on microalgae Phaeodactylum tricornutum, Chaetoceros sp. and Nanochloropsis sp. Average settlement rate and size for pentactula juveniles were closely to 9% and 0.5 mm, respectively, nearly one month post-fertilization (PF). However, a high mortality of 70% was observed during early larval development caused by ciliated protozoans and copepods attack. The culture of H. scabra population in Oman is thus promising but further research is needed to ensure higher survival rates, particularly in the early larval stages where adequate water filtration and sterilization is essential.

By: Lisa Fajar Indriana, Yuli Afrianti, Sitti Hilyana, and Muhammad FirdausSandfish Holothuria scabra is marine commodities with a high economic value. Overfishing of natural stocks has compelled an interest to begin aquaculture practice. Settlement is a critical phase for the planktonic larvae as they will transform to benthic form in the presence of substrate. This study aims to evaluate the settlement preferences, growth, and survival rate of H. scabra larvae settled on different seagrass leaves. The research was conducted using the Completely randomized design with four different species of seagrass leaves and five replications. The treatments consist of Enhalus acoroides (L-1), Syringodium isoetifolium (L-2), Cymodocea serrulata (L-3), and Cymodocea rotundata (L-4). Initial number of larvae was 1,000 individuals and the substrate was set with same widthof 12 cm x 17 cm for each unit. Results of the experiment indicated that settlement preference and survival rate of H. scabra larvae was significantly affected by seagrass used as substrate while no significantly differences was observed for growth of larvae. E. acoroides showed the best result with 0.26 ind. cm-2 settelement preference and 10.66% survival rate, so that suitable to be used as settlement substrate in H. scabra hatchery.
