Abstract:

According to the data of landing survey of 898 fishing vessels in the six fishing port of Hainan Island in 2015 before and after the summer fishing moratorium (SFM), in order to evaluate the SFM in the South China Sea on the recovery of fishery resources, the catch indexes before and after SFM were compared. The results showed the following: 1) Both light purse seining and single bottom trawl were the main fishing types in the offshore fishing grounds of Hainan Island before and after SFM, accounting for 36.18% and 43.67% of the total output of fishing vessels, respectively. 2) After SFM, the average CPUE of light purse seining, single bottom trawl, gill net and Hooking vessels increased by 41.14%, 20.85%, 7.86% and 33.73%, while the CPUE of commercial species increased by 19.06%. 3) The proportion of total catch of the main economic species increased by 10.07% after SFM, while the Cephalopods and Family Sparidae became the main economic species. 4) The average daily output and output value of different types of fishing vessels were significantly different before and after SFM (P<0.05), and the average growth rates were 14.92% and 49.55%, respectively. To sum up, the implementation of the SFM could improve the status of fishery resources and increase the efficiency of fishing production in the offshore fishing grounds of Hainan Island.
