SBC LTER: Santa Cruz Island: Abundance of Surfperch and Garibaldi

These data describe the abundance and age structure of select fish species at 11 sites on the North coast of Santa Cruz Island. The study was initiated in 1982, in the Santa Barbara Channel, California, USA, and this dataset is updated annually. The abundance and age structure of all Black, Striped, Pile and Rubberlip Surfperch as well as Garibaldi encountered are recorded at permanent transects in three depth strata at at each of 11 sites. In these surveys, fish are counted along a 40m x 2m transect, counting all individuals in the water column and in the understory algae.

本数据集记录了圣克鲁斯岛（Santa Cruz Island）北海岸11个调查站点的选定鱼类物种的丰度与年龄结构。本研究于1982年在美国加利福尼亚州圣巴巴拉海峡启动，且本数据集每年更新一次。在11个站点各自的三个深度层的永久样带上，研究人员对观测到的黑海鲫（Black Surfperch）、条纹海鲫（Striped Surfperch）、桩海鲫（Pile Surfperch）、厚唇海鲫（Rubberlip Surfperch）以及加里波第鱼（Garibaldi）的丰度与年龄结构进行记录。本次调查沿40米×2米的样带开展，统计水层及藻层下层中的所有鱼类个体。
