Description:

Monitoring fish populations at rocky offshore banks is challenging, but vital for the sustainable management of groundfish stocks. Deep banks provide important rocky habitats for commercially important species and can also act as a refuge from fishing. Imagery acquired by manned and unmanned underwater vehicles can be used to supplement data from more traditional trawl surveys, which are not suited to high-relief substrates. To explore the potential of three different vehicles to quantify groundfish, surveys were conducted with a submersible (SUB), a remotely operated vehicle (ROV), and an autonomous underwater vehicle (AUV) at two banks in the Southern California Bight. Here we present the results of the AUV survey, carried out in October 2011 based on a stratified random sample design. In total, 64,470 m2 were surveyed across The Footprint and Piggy Bank, and 22,249 fishes in 54 taxa were recorded from the AUV imagery. The total number of fish estimated for the area surveyed at the two banks was 5,511,922.
