Review of biological parameters for Ross Sea skates
MacDonald Islands. The taxonomy needs to be resolved before biological parameters derived from populations ... outside the Ross Sea can be applied to Ross Sea skates. Length-weight regression relationships for male ... both sexes combined is: TLt = 101.3(1? e?0.308[t+1.30]). The best estimate of longevity in A. georgiana ... is 14 years. However this may be a considerable underestimate, and true longevity may exceed 20 years ...
