The paper discusses some principles to be considered in the formulation of a framework for the regulation of fisheries from an ecosystem perspective, under the Convention for the Conservation of Antarctic Marine Living Resources. An important task in this formulation is to derive subsiduary objectives for regulation which have a more rigorous scientific interpretation than the broad principles Read More

The mathematical model was used to shown that the distance between acoustic survey tacks is reasonable to be selected based on the typical size of the surveyed region, allowable relative error in the biomass estimate, and the variation coefficient of the concentration density values. It is recommended to use the suggested criterion in real hydroacoustic surveys.

It was carried out the otolith reading of more than 1100 specimens of Micromesistius australis, caught in waters of the southern Argentine Sea during the cruises made by the ships Walther Herwig and Shinkai Marú in agreement with the Argentine Republic, in the years 1978 and 1978/79 respectively. For the interpretation of the growth rings, the otoliths were previously subjected to the paraffin Read More

This paper contains advice on determining mesh selectivity factors for trawl codends using a special liner. The design and technical specifications of the liner are described.
It also describes an experiment to determine the accidental mortality of fish passing through the trawl codend.
It contains proposals on standardising data collection and handling for mesh selectivity studies
