SBC LTER: Reef: Abundance, size and fishing effort for California Spiny Lobster (Panulirus interruptus), ongoing since 2012

Data on abundance, size and fishing pressure of California spiny lobster (Panulirus interruptus) are collected along the mainland coast of the Santa Barbara Channel. Spiny lobsters are an important predator in giant kelp forests off southern California. Two SBC LTER study reefs are located in or near the California Fish and Game Network of Marine Protected Areas (MPA), Naples and Isla Vista, both established as MPAs on 2012-01-01. MPAs provide a unique opportunity to investigate the effects of fishing on kelp forest community dynamics. Sampling began in 2012 and is ongoing. This dataset contains two tables. 1) Abundance and size data collected annually by divers in late summer before the start of the fishing season at five SBC LTER long term kelp forest study sites: two within MPAs (Naples and Isla Vista) and three outside (Arroyo Quemado, Mohawk and Carpinteria). 2) Fishing pressure, as determined by counting the number of commercial trap floats. Data are collected every two to four weeks during the lobster fishing season (October to March) at nine sites along the mainland, eight of which are also SBC LTER long-term kelp forest study reefs.

本数据集收录了圣巴巴拉海峡（Santa Barbara Channel）大陆沿岸加州棘刺龙虾（*Panulirus interruptus*）的丰度、体型与捕捞压力相关数据。棘刺龙虾是南加州近海巨藻林生态系统中的关键捕食者。本研究涉及的2个圣巴巴拉海峡长期生态研究（Santa Barbara Channel Long-Term Ecological Research, SBC LTER）样礁，位于加州鱼类与野生动物局（California Fish and Game）海洋保护区（Marine Protected Area, MPA）网络内或其邻近海域：那不勒斯（Naples）与伊斯塔维斯塔（Isla Vista），二者均于2012年1月1日正式设立为海洋保护区。海洋保护区为探究捕捞活动对巨藻林群落动态的影响提供了独特研究契机。本数据集的采样工作始于2012年，目前仍在持续进行中。本数据集包含两张数据表：1. 丰度与体型数据：每年夏末正式捕捞季开启前，由潜水员在5个SBC LTER长期巨藻林研究样地采集所得，其中2个样地位于海洋保护区内（那不勒斯与伊斯塔维斯塔），其余3个样地位于保护区外（阿罗约·肯梅多Arroyo Quemado、莫霍克Mohawk与卡平特里亚Carpinteria）；2. 捕捞压力数据：通过计数商业捕捞浮笼数量测算捕捞压力，在龙虾捕捞季（10月至次年3月）期间每2至4周采样一次，覆盖沿岸9个采样点，其中8个采样点同时为SBC LTER长期巨藻林研究样礁。更多详细信息请参阅《研究方法》部分。
