Study on Present Situation of Fishery Resource in Coastal Waters of Guangxi Based on Gillnet Fishing Vessel Production Survey
摘要
Abstract
The coastal waters of Guangxi are important spawning grounds,nursery grounds and feeding grounds for fishery organisms in Beibu Gulf.It is of great significance for fishery management and fishery re-sources conservation in Beibu Gulf to timely grasp the current situation of fishery resources in the coastal wa-ters of Guangxi.Therefore,this study used the production data of gillnet fishing vessels in Guangxi from Jan-uary to December 2023 to analyze the monthly unit fishing effort(CPUE)of 14 important economic fish,4 Crustaceans,3 Cephalopoda and 1 Shellfish,and compared the inter-annual variation of CPUE of target spe-cies from 2022 to 2023.The monthly statistics of CPUE showed that in January,April,August,November and December,17 of the 22 target species reached the maximum CPUE of the whole year,which was the peri-od of abundant fishery resources in the coastal waters of Guangxi.The comparison result of annual CPUE values of target species in 2022 and 2023 showed that 10 fish species such as Stromateidae,Parargyrops edi-ta,Mugilidae,Sillaginidae,Platycephalidae,Konosirus punctatus,Sparidae,Lateolabrax japonicus,Sela-chomorpha,Rajidae & Dasyatidae decreased.While 4 fish species as Soleidae & Cynoglossidae,Thamnaconus modestus,Johnius sp.,Siganidae increased.The number of Squillidae and Charybdis increased,while Penaei-dae and Portunus decreased.Cephalopoda increased,while Shellfish decreased.The total catch of CPUE de-creased and increased species accounted for 64.93%and 12.94%of the total catch,respectively.According to the research,the amount of fishery resources in the coastal waters of Guangxi in 2023 is lower than that in 2022,and the mass death of aquatic organisms in the coastal waters of Guangxi from July to September 2023 is the main reason for the decrease of fishery resources.关键词
