| 摘要: |
| 广西近岸海域是北部湾渔业生物的重要产卵场、育幼场和索饵场，及时掌握广西近岸海域渔业资源现状，对北部湾渔业管理、渔业资源养护具有重要意义。因此，本研究利用2023年1-12月广西刺网渔船生产数据，分析渔获物中14种重要经济鱼类、4种甲壳类、3种头足类和1种贝类的月度单位捕捞努力量渔获量(CPUE)，并比较2022-2023年目标种类CPUE的年际变化。CPUE的月度统计表明：1月、4月、8月、11月、12月，22个目标种类中共有17个种类CPUE达到全年最大值，是广西近岸海域渔业资源量较丰富的时段。CPUE年均值的比较结果如下：鲳鱼(Stromateidae)、二长棘鲷(Parargyrops edita)、鲻梭鱼(Mugilidae)、鳞鱚(Sillaginidae)、鲬(Platycephalidae)、斑鰶(Konosirus punctatus)、其他鲷类(Sparidae)、日本花鲈(Lateolabrax japonicus)、鲨鱼(Selachomorpha)、鳐魟类(Rajidae & Dasyatidae)等10种鱼类减少，鳎类(Soleidae & Cynoglossidae)、马面鲀(Thamnaconus modestus)、叫姑鱼(Johnius sp.)、蓝子鱼(Siganidae)等4种鱼类增加，虾蛄(Squillidae)和蟳类(Charybdis)增加，对虾(Penaeidae)和梭子蟹(Portunus)减少，头足类增加，贝类减少；CPUE下降和增加种类的捕捞产量合计占渔获总量的比例分别为64.93%和12.94%。研究认为，2023年广西近岸海域渔业资源量比2022年减少，2023年7-9月广西近岸海域水产生物群体性死亡是造成渔业资源量减少的主要原因。 |

| 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 resources conservation in Beibu Gulf to timely grasp the current situation of fishery resources in the coastal waters of Guangxi.Therefore,this study used the production data of gillnet fishing vessels in Guangxi from January 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 species 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 period 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 edita,Mugilidae,Sillaginidae,Platycephalidae,Konosirus punctatus,Sparidae,Lateolabrax japonicus,Selachomorpha,Rajidae & Dasyatidae decreased.While 4 fish species as Soleidae & Cynoglossidae,Thamnaconus modestus,Johnius sp.,Siganidae increased.The number of Squillidae and Charybdis increased,while Penaeidae and Portunus decreased.Cephalopoda increased,while Shellfish decreased.The total catch of CPUE decreased 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. |
