Training Workshop on Sharks and Rays Stock Assessment

The SEAFDEC Training Department (TD) organized the “Training Workshop on Sharks and Rays Stock Assessment by Using YPR Model” at Training Department, Samut Prakan, Thailand from 4 to 9 June 2018. There were 24 participants from SEAFDEC Member Countries participated in the workshop. This training course aimed to enhance human resource development on stock assessment of sharks and rays to researchers of SEAFDEC Member Countries, increase the number of stock assessment information for sharks and rays by species in the region, and establish a network of stock assessment scientists in the Southeast Asian Region. At the end of this training course, the participants were expected to understand on stock assessment by using Yield Per Recruit (YPR) Assessment Model through increasing the number of stock assessment information of sharks and rays by species, and a network of stock assessment researcher. Finally, YPR assessment model is commonly used to test alternative management strategies when historical information on recruitment for the fish population being studied is limited. Like many other types of fisheries models, a primary assumption implied in YPR models is randomness in the distribution of fish and effective fishing efforts throughout the fishery.
