Aquaculture Development

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.

Juvenile Density

The effects of sea cucumber (Holothuria scabra) juvenile density and interspecific competition from the opisthobranch Stylocheilus striatus (SS) on periphyton biomass and growth performance of H. scabra (HS) were assessed. The number of H. scabra juveniles (15, 50, 100) in net enclosures (treatments HS15, HS50, and HS100) was varied and feeding activity of S. striatus was assessed at a density of 15 individuals per net enclosure (treatment SS15), and in co-culture with H. scabra (treatment HS15/SS15). A control treatment without H. scabra or S. striatus was included in the 28-d experiment. Highest and lowest growth rates of H. scabra occurred in the lowest (HS15) and highest (HS100) stocking density treatments, respectively, on days 14 and 28. Growth of H. scabra juveniles in the HS15 treatment was more than double that of those in the HS15/SS15 treatment. Juvenile survival was significantly higher in the HS15 treatment on days 14 and 28, but did not differ significantly from that of juveniles in the HS15/SS15 and HS50 treatments on day 14. Grazing activity of sea cucumber juveniles and S. striatus resulted in a decline in periphyton biomass (AFDW) after day 7. Differences in food consumption (based on faecal production) among treatments were significant only on days 1 and 21 with the greatest consumption (17.5 mg periphyton ind−1 d−1) by S. striatus in the SS15 treatment. Holothuria scabra juveniles in the HS15 treatment consumed 4.9 mg ind−1 d−1, while those in the HS100 treatment consumed only 1.8 mg ind−1 d−1 after 24 hrs.

Background: Holothuria scabra is one of the most commercially important species found in the Pacific region. The sea cucumber extracts have been widely reported to have beneficial health effects. The aim of this study was to determine the nutritional compositions of H. scabra, and compare its important nutritional contents with that of other species.Methods: The sea cucumbers were dissected, sliced into small pieces, and then freeze-dried. The nutritional compositions, including proximate composition, amino acids, fatty acids, collagen, GABA, Vitamin A, C, and E of the whole body and body wall of H. scabra, were analyzed.Results: H. scabra contained a high quantity of protein (22.50% in whole body and 55.18% in body wall) and very low lipids (1.55% in whole body and 1.02% in body wall). The three most abundant amino acids found in both the whole body and body wall were glycine, glutamic acid, and proline. The main fatty acids found in the whole body were stearic acid and nervonic acid, and in the body wall were arachidonic acid and stearic acid. The whole body and body wall also contained high levels of essential amino acids, essential fatty acids, and collagen, in addition to moderate amounts of vitamin E and low amounts of GABA and vitamin C.Conclusions: The sea cucumber, H. scabra, contained high quantity of protein and very low lipid. It contained high essential amino acids, essential fatty acids, nervonic and arachidonic acids, and collagen, which also contained GABA, vitamin C, and vitamin E.Keywords: sea cucumber; Holothuria scabra; nutrition components; functional food

This research is conducted in the coastal waters of Bahoi Village, West Likupang Sub-district, North Minahasa District with the aims to know the types of sea-related environmental factors in the research site and know the community structure of the sea cucumber including the density, Index of diversity, dominance index, and distribution patterns. Data collection was done by using the line transect method, and sampling technique by using quadrat. The results of the study found 5 species of sea cucumber i.e. Holothuria atra,  Holothuria scabra,  Bohadschia marmorata, Actinopyga echinites, and  Bohadschia vitiensis. The individual density of all species is 0.12 ind/m2, and the diversity index (H ') 0.950. The value of the similarity index/compatibility obtained is e = 0.918. The result of the calculated dominance index of sea cucumber species is 1.0 and the pattern of spreading species of sea cucumber in the research site shows a random spread pattern because the value of dispersion index  (I) approaches 1 (one). Keywords: community; Sea cucumber; Bahoi; Dominance; Diversity.AbstrakPenelitian ini dilakukan di perairan pantai desa Bahoi, Kecamatan Likupang Barat, Kabupaten Minahasa Utara dengan tujuan untuk mengetahui jenis-jenis teripang yang ada di lokasi penelitian dan mengetahui struktur komunitas teripang yang meliputi kepadatan, indeks keanekaragaman, indeks dominasi, dan pola penyebaran.
