  1. REVISED AGE AND GROWTH ESTIMATES FOR ANTARCTIC STARRY SKATE, AMBLYRAJA GEORGIANA, FROM THE ROSS SEA

    that these skates initially grow very rapidly for about five years, after which growth almost ceases ... that is radically different from the published interpretation. By counting fine growth bands in the ... caudal thorns instead of broad diffuse bands, we have generated growth curves that suggest much slower ... growth, greater ages at maturity (about 20 years compared with 6–11 years) and greater maximum ages (28 ...

  2. Hook selectivity in the longline fishery of Dissostichus eleginoides (Nototheniidae) off the Chilean coast

    fisheries of the patagonian toothfish Dissostichus eleginoides related with the selectivity of the type and ... East Pacific, are added. The data show that the circle hooks are far more efficient that the right ones ... . The size frequency of the population collected with straight hooks No3 and 4 are not significatively ... differences. It is notorious that female proportion increases significatively in the catches, at the same time ...

  3. CPUE values derived from Soviet fishery statistics as indicators of Antarctic krill density fluctuations in 1977–1991

    - 1991 are considered. It is assumed that these values adequately describe trends in krill density ... fluctuations. Rather high stability of the values investigated is revealed. It is proposed that krill density ... of 170-200 g/m2 may be considered as an average characteristic value for the area 48. It was revealed ... , that interannual CPUEs variability is lower for the area 48 as a whole, comparing subareas, most ...

It cannot be accounted for by ... , except possibly for the increase in vessels engaged in long-line fishing, which uses bait boxes tied with ... packaging bands. CCAMLR needs to renew its vigilance with respect to marine debris and should consider ...

  6. Progress towards validation of ageing of Dissostichus eleginoides using otoliths

    , fish have been treated with strontium to mark their otoliths for validation of subsequent age ... estimation. Otoliths from 69 fish that were at liberty for at least 350 days were eventually examined ... . Results indicate that current methods for ageing D. eleginoides are appropriate: the number of observed ... annuli on the otoliths after the strontium mark was consistent with the time at liberty of the fish after ...

For R=10%, it is estimated that a krill harvesting intensity rate γ of ... slightly more than 0.1 would be required to reduce the seal population to half its pre-exploitation level ... -related mortality effects from overall survival rate data before they can be taken further.
