Surveys and classification of surfperch

This metadata record documents target species surveys of surfperch, redtail surfperch, Amphistichus rhodoterus, and siver surfperch, Hyperprosopon ellipticum, for the California North Coast MPA baseline characterization of sandy beaches conducted between June 2014 and November 2015. Sandy beach surf zones are important foraging grounds for surfperch. Redtail surfperch is the primary species taken by recreational beach anglers in northern California. Additionally, the largest commercial landings of redtail surfperch in California are through the port of Eureka. Redtail surfperch are traditionally fished and culturally important for north coast tribes. These organisms are easy to sample, identify, and enumerate and are thus excellent target species for monitoring. From the surveys we determined species, length, sex, and tagged any released fish.

本元数据记录记载了2014年6月至2015年11月期间，为加州北海岸海洋保护区（Marine Protected Area, MPA）沙滩基线特征描述而开展的目标物种调查，涉及滩鲈、红尾滩鲈（Amphistichus rhodoterus）及银滩鲈（Hyperprosopon ellipticum）。沙滩冲浪带是滩鲈的重要觅食地。红尾滩鲈是加州北部休闲滩钓者捕获的主要物种。此外，加州红尾滩鲈的最大商业上岸量经由尤里卡港实现。红尾滩鲈是北海岸部落的传统捕捞物种，具有重要文化意义。这些生物易于采样、识别和计数，因此是监测的理想目标物种。通过调查，我们确定了物种、体长、性别，并对所有放归的鱼类进行了标记。
