Summary: | Age and growth of Glyptocephalus stelleri in the East Sea of Korea were determined, from monthly samples of commercial catches, caught by the eastern sea Danish seine fishery in 2007. The annuli of G. stelleri are formed once a year, with the boundary between opaque and translucent zones forming in September. Relationships between total length (TL) and total weight (TW) were TW=0.002TL3.392 (r2=0.970) for females and TW=0.002TL3.335 (r2=0.961) for males. TLs at annuli formation in otoliths were backcalculated from the otolith-length relationship and were adjusted to von Bertalanffy growth curves to Lt=39.71(1 - exp (-0.152(t+1.156)) for females and Lt=32.16(1 - exp (-0.213(t+0.879))) for males. From the age of 3yerars, females grew faster than males (P<0.05). |
