The Atlantic States Marine Fisheries Commission’s Northern Shrimp Section has extended the moratorium on commercial fishing for the 2016 fishing season, in response to the depleted condition of the northern shrimp resource.
The 2015 Stock Status Report for Gulf of Maine (GOM) Northern Shrimp indicates abundance and biomass indices for 2012‐2015 were the lowest on record for the 32‐year time series. The stock has experienced failed recruitment for five consecutive years, including the three smallest year classes on record. As a result, the indices of fishable biomass from 2012‐2015 are the lowest on record.
Recruitment of northern shrimp is related to both spawning biomass and ocean temperatures, with higher spawning biomass and colder temperatures producing stronger recruitment. Ocean temperatures in western GOM shrimp habitat have increased over the past decade and reached unprecedented highs in 2011 and 2012. While 2014 and 2015 temperatures were cooler, temperatures are predicted to continue to rise as a result of climate change. This suggests an increasingly inhospitable environment for northern shrimp.
The Northern Shrimp Technical Committee considers the stock to have collapsed with little prospect of recovery in the immediate future.
“Considering survey indices are the lowest on record, with an unprecedented five consecutive years of weak recruitment and continuing unfavourable environmental conditions, the Section maintained the moratorium in 2016,” said Northern Shrimp Section Chair, Mike Armstrong of Massachusetts. “The Section is committed to protecting the remaining spawning biomass and allowing as much reproduction to take place as possible.”
