The Omani sandfish sea cucumber, Holothuria scabra Jaeger, 1833 (Holothuroidea: Holothuriidae): Fishery, length-Weight relationship and condition factor

The fishery of Omani sea cucumber, Holothuria scabra, is limited so far to the Mahout Bay in Al Wusta governorate. This fishery supports an uncertain number of fishermen ranging from 100 to 150. This fishery is not well-studied and has no current management program. In order to prepare a management strategy, the government has suspended this fishery for 2 years from March 2018 to March 2021. Apart from presenting a thorough review on the sea cucumber fishery in Oman, the current work presents a detailed analysis of the length–weight relationship, sex ratio, and condition factor of the H. scabra collected from four different areas during the period February-May 2019. Based on the results, the females were longer than males, that is 226±33.4 and 221±37.8 mm, respectively. The overall sex ratio of the entire/pooled sample was 0.49 which was not different from the anticipated theoretical sex ratio of 0.5. The mean Kn and the empirical weight–length equations for the total sample were between 0.12±0.01 and 1.0±0.16, and W=0.03L^1.6, respectively.
