Proposal for a skate tagging program in the Ross Sea region to estimate the local biomass trend for starry skates (Amblyraja georgiana)
survival assumed), would be about 0.6% of the Chapman estimate of biomass estimated from the tag release ... and recapture data. This is less than half of the gamma for this species, which we estimated to be ... hence we recommend that a 2-year skate tagging programme in the Ross Sea region be used to provide ...
