* In 1997 and 1998, a natural disease resulted in a major die-off of oyster stocks. Visit the Shellfish Disease page for more information.

** Prior to 2004, harvest quantity was calculated in bushels. Subsequent data are calculated in 100-count bags (for oyster, and chowder and cherry hard clams) and 200-count bags (for top neck and little neck hard clams).

*** The largest cultivated acreage producer failed to report harvest statistics from 2008 to 2010. As a result, the overall average harvest growth rate was factored into the last reported figures by the company to obtain an estimate for 2010 harvest numbers. However, no growth was factored for 2008 harvest numbers.

**** The COVID-19 pandemic disrupted the shellfish market, reducing the annual sales in 2020.


2024 Hard Clam Economic Impact Update

The shellfish industry was significantly impacted by the COVID-19 pandemic due to immediate and prolonged loss of markets as seafood distribution facilities and restaurants closed. While Connecticut oyster landings have since recovered to the past seven-year annual average, hard clam landings have continued to decline. Annual sales have decreased since the annual maximum of $20.5 million in 2008 to just over $2 million in 2023. Landings have steadily declined, with no evidence of economic recovery, since 2008.

The declining hard clam market has compounded the economic impacts of the COVID-19 pandemic. Shellfish companies have reported declining hard clam recruitment, which has subsequently limited stocks throughout the state for over a decade. Based upon historic harvest, some industry members believe that large hard clam sets only occur every 30 years in Connecticut. Based upon the large landings in the 1990’s and 2000’s, this 30 year “boom” could be decades out.

Hard clam harvesting began in the late 1950’s, targeting an abundance of chowder clams. While the initial clam dredges were very inefficient, the industry developed an effective and efficient hydraulic clam dredge in the 1970’s. Independent little neck clam harvesters joined the market in the 1980’s prior to the market boom. The hard clam market expanded out of necessity, as lobster landings were decreasing and oyster populations significantly declined due to a disease outbreak in the 1990’s. In the 1990’s, many lobstermen became licensed hard clam harvesters following an unusually high recruitment level of hard clams that produced a large amount of high value little neck clams. Subsequently, the hard clam population sustained up to 50 licensed harvesters until 2020.

Of the 31 licensed operations in 2024, there are 18 oyster operations, 7 hard clam operations, and 6 oyster and hard clam operations. Significant consolidations have occurred over the past four years, resulting in the reduction of 50 operations to 31. There are five small hatchery seed oyster aquaculture growers seeking permits that will eventually be licensed harvesters.

The 13 companies who rely on hard clams as part of their business model are currently experiencing an unprecedented economic loss, to the point that their vessels may only fish 1-2 days per week. These reduced schedules make it difficult to maintain experienced employees and a viable income. Due to the declining availability of hard clam stocks, operation’s margins are becoming increasingly tight as they must continue to maintain their vessels and gear with less income.

Without an alternative, many of these hard clam harvesters will be forced to seek alternative employment. Utilizing these experienced operators and their vessels to perform portions of shellfish restoration projects could assist in sustaining companies while restoring the State public natural seed beds. As grant funded restoration projects are proposed, the Bureau will insist that these vessels be used for rehabilitation and enhancement work.
