Age- and length-at-maturity of female arrowtooth flounder (Atheresthes stomias) in the Gulf of Alaska
Arrowtooth flounder (Atheresthes stomias) has had the highest abundance of any groundfish species in the Gulfof Alaska since the 1970s (Matarese et al., 2003; Turnock et al., 2005; Blood et al., 2007); however, commercialcatches have been restricted because Pacific halibut (Hippoglossus stenolepis)...
