August 9, 2016 — The American Lobster Management Board has released a draft plan responding to declining stocks of lobsters in Southern New England waters that will be considered by the Atlantic States Marine Fisheries Commission at its annual meeting in late October.
The proposal presents a suite of management measures to increase egg production and lower harvesting mortality through a combination of management tools that include season closures, trap limits and reductions and changes in escape vent and lobster size regulations. The goal is to increase egg production for lobsters in Southern New England waters from zero to 60%.
The draft responds to the 2015 American lobster benchmark stock assessment that found the Southern New England “stock severely depleted and undergoing recruitment failure with poor prospects of recovery,” according to Friday’s statement from ASMFC.
“Declines in population abundance were most pronounced in the inshore portion of the stock where environmental conditions have remained unfavorable to lobsters since the late 1990s,” according to ASMFC. “Despite fleet attrition, stock declines have continued. These declines are largely in response to adverse environmental conditions including increasing water temperatures over the last 15 years combined with continued fishing mortality.”
ASMFC reported that declines in in the offshore portion of the fishery were evident as well though not as severe. But it also noted the offshore portion of the Southern New England stock depends on a viable population of young lobsters in waters closer to the shore.
The lobster stock in Southern New England increased from the early 1980s, peaked during the late 1990s and then started declining steeply to a record low in 2013, according to ASFMC’s 2015 benchmark study. The study attributes the decline as being largely due to “increasing water temperatures over the last 15 years combined with sustained fishing mortality.”
