Study of Length-Weight Relationship and Condition Factor of Sandfish Sea Cucumber (Holothuria scabra)

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