“…Ideal aquatic environmental conditions can support the sandfish H. scabra's growth. This result can also indicate water quality parameters in the habitat for living of sandfish sea cucumbers is within the optimal range (Manuputty, 2019;Meirinawati et al 2020). The water quality parameters measured in this study are supporting data to describe the condition of the waters when the sandfish H. scabra was found (Table 4).…”

The overfishing of the sandfish Holothuria scabra is increasing due to its various benefits, thus reducing its population in nature. This study aimed to examine sandfish's length-weight relationship and condition factors on the North Coast of Sumbawa Island, with sampling locations at two stations, Ai Limung (Pungkit Village), and Labu Prajak (Batu Bangka Village). The study was conducted in September-October 2022. A total of 142 specimens were obtained from both stations, 122 samples at Ai Limung station (mean length 9.22±2.12 cm; weight 43.34±25.07 grams). Then 20 samples at the Labu Prajak station (mean length 13.69±3.74 cm; weight 88.70±60.06 grams). Growth patterns of each research station are negative allometric, indicating the body length of the sandfish grows faster than its weight. Condition factor at Ai Limung station Kn=1.03±0.26, Wr=1.03±0.26, K=5.33±1.76, and at the Labu Prajak station Kn=1.05±0.28, Wr=104.88±27.83, K=3.27±1.14. The results showed significant differences in length, weight, and fulton condition factor. The mean body length and weight of sandfish at both stations are smaller than previous study, indicating the earlier sign of overfishing. Meanwhile, the fulton condition factor at Ai Limung station showed a higher value, which indicated the location was better, with abundant food sources and fewer predators

“…Sandfish sea cucumber can live at a pH with optimal conditions in the range of 7.5-8.5. However, if the pH is above 9 or below 6, the growth of sandfish H. scabra will be disrupted (Meirinawati et al 2020).…”

Milkfish (Chanos chanos) and sea cucumbers (Holothuria scabra) are fishery commodities that can grow well in ponds. The commodities have different feeding habits. Polyculture trials in controlled tanks are possible. This study aimed to determine the growth and survival of sea cucumbers reared in polyculture in tanks and to know whether sea cucumbers can use milkfish feces as feed. This study used 12 PE tanks of 500 L to ascertain that no other food sources were available in the tanks. The initial size of sea cucumber seeds was 3.4 – 5.4 cm and milkfish 19.0 – 22.5 cm. The treatments designed were (A) monoculture of sea cucumber (28.6 g/m2), (B) polyculture of sea cucumbers (28.6 g/m2) and milkfish (0.28 g/L), (C) polyculture of sea cucumbers (28.6 g/m2) and milkfish (0.56 g/L), and (D) monoculture of milkfish (0.56 g/L). Results showed that both monoculture and polyculture of sea cucumbers and milkfish resulted in high survival rates (100%). Although the polyculture of sea cucumbers showed no significant difference in growth, polyculture with milkfish (C) tended to have a higher final weight of sea cucumbers than the other treatments. Sea cucumbers could utilize milkfish feces and increase the growth of sea cucumbers.

“…The natural environment directly or indirectly controls the presence and abundance of macrobenthos (Schückel et al, 2015;Foulqquier et al, 2020), such as sea cucumber. Water quality (Meirinawati et al, 2020) and water movements through the transport of sediment and organic material, also strongly affect this bottom community (Koumianaki et al, 2013). Tanita and Yamada (2019) stated that environmental characteristics, both physical and chemical parameters, greatly affected the species composition, population, and distribution of sea cucumbers in their ecosystem.…”

Information on the environmental characteristics of many sea cucumber habitat is limited, despite these species exhibiting rapid exploitation and may lead to depletion. The present study combined a survey on many seawaters and sediment characteristics of habitat valuable aspidochirote holothurian, Sea Ball Cucumber, Phyllophorus sp. to compare with location with no sea cucumber in Madura Strait, Indonesia. Data from detailed surveys were used to compare both locations with measures of physical and chemical seawater parameters including temperature, salinity, dissolved oxygen, pH, phosphate, nitrate, ammonia, chlorophyll-a, total suspended solids, light transparency, and depth of water. The comparison was also carried out on physical and chemical parameters of surface sediment, i.e. phosphate, nitrate, ammonia, chlorophyll-a, grain size, total organic matter, and carbon-organic content. The data then were analyzed using Mann-Whitney U-Non Parametric Test with SPSS v. 16. The result revealed that there were significant differences between sediment characteristics of Sea Ball Cucumber habitat and no Sea Ball cucumber location, but not for seawater. Seawater parameter value in Madura Strait showed in the range required for its life. This analyzes proved the importance of sediment characteristics for Phyllophorus sp. As benthic deposit feeders, they did not only utilize substrate underneath the body for its habitat but also primarily to supply their natural food.
