Stock Status of Whitespotted Bambooshark, Chiloscyllium plagiosum (Anonymous [Bennett], 1830) in Sabah, Malaysia, Using Yield-Per-Recruit and Spawning Per-Recruit Analyses

Whitespotted bambooshark, Chiloscyllium plagiosum (Anonymous [Bennett], 1830), is a major shark species caught in waters off Sabah, Malaysia. Despite the massive landing amount, its biological and stock status information limited. In 2015–2016, elasmobranch data collection was conducted Southeast Asia, including Sabah. A yield-per-recruit (YPR) spawning-per-recruit (SPR) analyses were performed to assess this data-deficient species’ status.
