Project Title: AKCSI Project 1: Primnoa Habitat Areas in the Gulf of Alaska
Project Summary

This project will use a deep-diving ROV (or submersible) to verify the location of red tree coral (Primnoa pacifica) thickets, black coral (Chrysopathes speciosa, C. formosa, Bathypathes patula, and Lillipathes wingi) groves, and bamboo coral (Isidella tentaculum) groves that are apparent from bycatch rates from the annual NMFS sablefish stock assessment survey. 

Anticipated Management Application(s)

In 2007 the North Pacific Fisheries Management Council (NPFMC) under the recommendation of NOAA Fisheries scientists established several Habitat Areas of Particular Concern (HAPCs) in the Gulf of Alaska to protect sensitive coral habitats and the ecosystem services they provide. Submersible observations confirmed the presence of sensitive coral habitat at each site–a requirement for the establishment of an HAPC by the NPFMC. Using bycatch records from the annual NMFS sablefish stock assessment surveys we have identified several additional sites in the Gulf of Alaska that may harbor coral habitats appropriate for HAPC designation.
