August 14, 2026 — The following was released by Ocean Harvesters:
The F/V Calcasieu Pass, a retired menhaden fishing vessel formerly operated by Ocean Harvesters, was intentionally sunkWednesday, August 12, at Delaware Reef Site 13, approximately 26 miles off Indian River Inlet.
The Calcasieu Pass will now begin a second life as artificial reef habitat, adding structure for marine life and providing new opportunities for recreational fishing and diving off the Delaware coast.
Ocean Harvesters transferred the retired vessel to Coleen Marine for a nominal $1 purchase price in 2024, donating the Calcasieu Pass for conversion into an artificial reef. Coleen Marine subsequently prepared, towed and sank the vessel at the Delaware reef site.
“Retired working vessels can continue to provide value long after their fishing days are over,” said Monty Deihl, CEO of Ocean Harvesters. “We’re pleased to see the Calcasieu Pass begin a new chapter as marine habitat, supporting the ecosystem while creating new opportunities for anglers and divers.”
Menhaden vessels have a long history of being repurposed as artificial habitats. In 2023, the former F/V Mermentau and F/V G.P. Chauvin were intentionally sunk off the Mississippi coast as part of that state’s artificial reef program. Other retired vessels associated with the menhaden fishery have been deployed as artificial reefs in Louisiana, Delaware and Mississippi.
Another former menhaden vessel, the Reedville, was sunk off Delaware in 2020. Like the Calcasieu Pass, the vessel was prepared and deployed by Coleen Marine as part of Delaware’s artificial reef system.
Artificial reefs provide hard structure on otherwise largely featureless ocean bottom, creating habitat for marine organisms and attracting fish while expanding recreational fishing and diving opportunities. Delaware has developed a network of artificial reef sites along the Atlantic Coast and in Delaware Bay using retired vessels and other cleaned, stable materials.
The Calcasieu Pass deployment adds another retired working vessel to that network and extends a practice that allows vessels which spent decades supporting coastal fishing communities to continue serving the marine environment after their working lives have ended.
