Project Title: AKCSI Project 5. Effects of Longline Fishing on Coral Habitat in Alaska
Project Summary

The goal of this project is to examine the behavior of longline gear in situ in coral and sponge habitat. These observations will assist researchers in identifying longline disturbance in situ, provide additional estimates of damage rates, and provide insights regarding possible gear modifications to minimize interactions. 

Anticipated Management Application(s)

Disturbance from longline fishing to sensitive coral and sponge habitats has been documented in Alaska but the extent of and mechanisms of disturbance have not been well studied compared to bottom trawling. Observations in red tree coral thickets in the eastern Gulf of Alaska indicate that 17% and 20% of the “standing stock” of corals and sponges, respectively, have been damaged by longlines (Stone et al., in preparation). Corals and sponges are common bycatch in both commercial fisheries and stock assessment surveys using longlines clearly indicating interactions between the gear and sensitive habitats. The goal of this project is to examine the behavior of longline gear in situ in coral and sponge habitat. These observations will assist researchers in identifying longline disturbance in situ, provide additional estimates of damage rates, and provide insights regarding possible gear modifications to minimize interactions.
