Trawl Materials and Supplies

Procurement Summary

The Alaska Fisheries Science Center(AKFSC) requires trawl materials and supplies that that will be used for survey trawl repairs and to construct trawls in preparation for surveys and research conducted in Alaskan waters. A variety of materials are used to construct and repair these trawls, including wire rope, floats, Poly web, and assorted hardware. These materials must be the same from year to year, and the specifications must remain the same over time to ensure standardization. The AKFSCRACE Division Research Fishing Gear Program is responsible for the construction and repair of all trawls used for both survey and research purposes. There are a variety of trawl types that all have different characteristics to meet the requirements of the survey or research to be completed. Rope and twine looming techniques are held to secrecy and patented, where each manufacturer produces the specific fibers, natural or synthetic, used for their product. The rope and twine fibers are twisted and braided together to create a specific tensile strength. The specific fibers used and the tensile strength applied by each manufacturer is distinct and unique. The rope and twine selected for the AKFSC trawl nets must support a certain amount of stress when stretched. The constructed trawl net receives considerable impact and force when fishing on the sea floor, where the average catches within the trawl net is approximately 1,100 -1,200 kg. It is imperative that the rope and twine is manufactured to withstand the stress and weight of both the bottom fishing and the resultant catch.
