摘要Objective: To evaluate exploitation status of the stocks of demersal fishes in Omani artisanal fisheries. Methods: Time-series data between 2005 and 2014 on catches and effort represented by the number of fishing boats were used to estimate catch per unit effort and maximum sustainable yields applying Schaefer surplus production model. Regression analyses were made online using GraphPad software. Results: The study revealed that increasing the number of boats on the fishery caused a decrease of catch per unit effort of some species. Maximum sustainable yields and exploitation status were estimated for these species applying. Conclusions: Some demersal fish species were found to be caught in quantities exceeding maximum sustainable yields during some fishing seasons indicating overexploitation of their stocks.
