4. Age and growth of the Antarctic skate (Amblyraja georgiana) in the Ross Sea

   the curve for both sexes provides the best available representation of growth in the species: Lt ... = 70.8(1-e-0.308[t+1.10]), where Lt is the pelvic length (PL) in centimetres at age t. Applying this ...

5. Global MPAs and marine reserves: lessons learned and implications for CCAMLR

   statistically significant outcomes on fish population metrics, including: “no take, well enforced, old (>10 ... years), large (>100km 2) and isolated by deep water or sand” (Edgar et al. 2014). Two analyses of New ...
