资源简介:
Measuring fishing effort is important for assessing the environmental sustainability of fish stocks and the socioeconomic efficiency of fishing activity. Fishing effort describes the amount of fishing gear used on a fishing ground over a given unit of time. Effort in this case is defined as number of creels hauled per day per 4 km2. This survey interviewed 198 creel vessel skippers from four regions, two on the west and two on the east coast of Scotland. This analysis has been produced from these SAMPLED vessels only. This IS NOT a census and IS NOT a map of all creeling effort in these waters or in the survey areas. This is an indication of potential fishing effort only and if creeling is not quantified in an area in this map, that DOES NOT mean creeling is not taking place. Equally quantified effort could be higher given some creeling vessels were not surveyed. Fishing effort outside of the surveyed area was not measured.
衡量捕鱼强度对于评估鱼类资源的生态环境可持续性以及捕鱼活动的社会经济效率具有重要意义。捕鱼强度是指在特定时间段内,在捕鱼区域所使用的捕鱼工具数量。在此,捕鱼强度被定义为每日每4平方公里所捕获的鱼篓数量。本次调查对来自苏格兰四个地区的198艘鱼篓渔船船长进行了访谈,其中西部和东部沿海各有两处。本分析仅基于这些抽样渔船数据。这并非全面调查,也非该水域或调查区域内所有捕鱼强度的详图。这仅是潜在捕鱼强度的一个指示。若图中所标示的区域未对鱼篓捕捞进行量化,并不意味着该区域未进行捕鱼活动。鉴于部分捕鱼船未参与调查,实际量化强度可能更高。调查区域之外的捕鱼强度未进行测量。
