2017 Developing a method for assessing blueline (Caulolatilus microps) and golden (Lopholatilus chamaeleonticeps) tilefish stocks using a baited underwater video system

Project Title: 2017 Developing a method for assessing blueline (Caulolatilus microps) and golden (Lopholatilus chamaeleonticeps) tilefish stocks using a baited underwater video system

Year: 2017

Principle Investigators: Liese Siemann, Samir Patel, and Farrell Davis

Client: NOAA/NMFS Saltonstall-Kennedy Program

The goal of this project will develop innovative supplemental surveys (proof of concept) to derive fishery-independent indices of abundance for blueline (Caulolatilus microps) and golden (Lopholatilus chamaeleonticeps) tilefish. Specifically, it will determine the feasibility of using pelagic baited remote underwater video (BRUV) systems to assess tilefish populations. Golden and blueline tilefish are important recreational and commercial fish species. Commercial landings in 2014 were valued in excess of $10 million. Currently, there is no fishery-independent assessment for either species, and developing appropriate surveys is a management priority. Video surveys are now routinely used for sea scallop assessments, and BRUV systems are used to collect fishery-independent data for commercially harvested reef fish.
