Project Title: Exploring off-bottom trawling and other approaches to avoid interactions with structure-forming invertebrates during Pacific Ocean perch fishing on the Bering Sea slope
Goal or Purpose

This project will demonstrate technologies to routinely measure the clearance between rockfish fishing gear and the seafloor. An acoustic altimeter will be designed to allow continuous, frequent, unattended monitoring of clearance between the footrope and/or fishing line of rockfish trawls and the seafloor during routine rockfish trawling. This device will be mounted on the trawl’s footrope throughout the study to measure clearance and confirm effectiveness. A footrope camera system will be deployed to observe footrope, rockfish, and seafloor (including structure-forming invertebrates (SFI)) during a two-week trip aboard a Bering Sea trawler in the Pacific Ocean perch fishery, using separate trawls designed to be fished on-bottom and offbottom. Camera imagery and headrope-mounted sonar will show both rockfish and SFI near the footrope and the proportion of rockfish above that area. This information will be analyzed to compare possible gear designs, trawl clearances and rockfish fishing locations to minimize SFI interactions.

This project is co-sponsored by the DSCRTP and the National Bycatch Reduction Engineering Program (BREP). Both programs seek to develop techniques to reduce interactions between fishing gears and corals/sponges. This project is administered by BREP and implemented by FishNext Research.
