Whelk Pot - Brooks Trap Mill
48″L x 39″W x 16½”H – Built with ½” x ½” and 1½” x 1½” mesh wire, these oddly-shaped traps are equipped with wire entrance heads, three oak runners, two escape vents, and a dump door.
Pots and Traps - Whelks - Seafish
Whelk pots are handled in fleets exactly the same as most other pots. Due to their relatively small size, although they do tend to be heavy, many vessels will operate fleets with greater number of traps in them.

Whelks and Whelk Management - Mass.gov
As a shellfish predator, whelks were historically considered a nuisance species. By the late 1900s, foreign and domestic consumer markets for whelks began to emerge, and with that, fisherman began landing whelks caught as bycatch in lobster trap, otter trawl and shellfish dredge fisheries.
Whelk (Mollusca: Family Melongenidae) harvest potential and pot efficiency of four different experimental traps (modified crab trap, plastic rectangular trap, plastic pyramid trap, and mesh pyramid trap) were compared for catch efficiency against a standard crab trap from May 10, 2006 to June 27, 2006 in coastal Georgia waters.
Whelks | Department of Marine Resources
Whelks in Maine have traditionally been landed as an incidental by-catch of the lobster fishery, with only a handful of harvesters utilizing specially designed whelk traps in a directed effort. The product is typically shipped live for mostly ethnic (oriental) markets in Boston and New York City.
The current trap is designed to catch whelk of all sizes with no means of escape anywhere on the trap, differing from the standard in the lobster fishery which incorporate escape vents.
New UNH Research Aims to Make Channeled Whelk Fisheries …
2023年6月5日 · The scientists have been testing modified whelk traps with escape vents, looking for a design that retains the greatest number of legal-sized whelks and lets out the most sublegal-sized whelks and that is also cost-effective for fishermen to do on their own.
Size selectivity of drum-net traps for whelk - ScienceDirect
2007年9月1日 · The traps with 55 and 75 mm mesh and the traps fitted with escape rings all had statistically significant lower estimated efficiency than the control trap. Although the double hoop traps appear to offer the greatest potential for reducing the catch of undersized whelk, these traps are the most difficult to construct, store and deploy.
Redesign Of Channeled Whelk Traps For Improved Selective …
After multiple trials and review, a finalized gumdrop shape trap door design has been found to show the most significant improvements for allowing the majority of sublegal whelk to escape. The final design, among other valuable information learned during the past year about these animals, will continue to push forward new improvements for whelk ...
