F. Martini et al., A POPULATION PROFILE FOR ATLANTIC HAGFISH, MYXINE-GLUTINOSA (L), IN THE GULF-OF-MAINE .1. MORPHOMETRICS AND REPRODUCTIVE STATE, Fishery bulletin, 95(2), 1997, pp. 311-320
Populations of Atlantic hagfish, Myxine glutinosa (L.), are found thro
ughout the Gulf of Maine in soft-bottom substrates at depths greater t
han 50 m. This report presents data on the sizes, weights, morphometri
c characters, and reproductive states for specimens collected at a stu
dy site approximately 50 km offshore in the Gulf of Maine. Limited com
parisons with data from specimens collected elsewhere suggest that thi
s data set is representative of hagfish populations within the inner G
ulf of Maine. The small number of eggs produced (less than 30 per fema
le), the large number of animals without macroscopically visible gonad
al tissue (25% of the population), and the small number of males (<6%
of the population), gravid females (<1%), and postovulatory females (<
5%) suggest that hagfish have limited reproductive potential. This rai
ses serious questions about the long-term viability of the New England
eelskin fishery.
