Spiny Lobster Population Data, Santa Catalina Island (West End), CA USA, 2003-2005

Basic morphometric and demographic data was collected for the spiny lobster, Panulirus interruptus, around the west end of Santa Catalina Island from Spring 2003-Spring 2005. This region includes two marine protected areas, many popular sport fishing and diving sites, and a continuous stretch of coastline that is commercially fished. Lobsters were caught using commercial lobster traps without juvenile escape ports and mackerel as bait. Traps were set on the first day at randomly selected sites within a blocked sampling scheme and allowed to sit overnight. On the second day, traps were collected and all lobsters within were evaluated on a number of parameters including (but not limited to) carapace length, weight, gender, and fertility state. Animals were marked with either a uropod punch code, colored cable tie, or floy tag to determine movement patterns and growth rates in the event of recapture.

本数据集采集了2003年春季至2005年春季期间，圣卡塔利娜岛（Santa Catalina Island）西海岸周边的棘刺龙虾（Panulirus interruptus）的基础形态计量学与种群统计数据。该区域涵盖两处海洋保护区、多处热门休闲垂钓与潜水点位，以及一片持续开展商业捕捞的连续岸线。本次采样使用无幼体逃逸口的商业龙虾笼，以鲭鱼作为诱饵进行捕捞。按照区组抽样设计，于采样首日将诱笼布设至随机选定的点位，并留置整夜。次日回收诱笼，对笼内所有龙虾开展多参数评估，评估指标涵盖（但不限于）甲壳长度、体重、性别与生殖状态。研究人员为每只受试龙虾标记尾肢打码、彩色扎带或弗莱标签（Floy Tag），以便在重捕时追踪其移动模式与生长速率。
