Hake and spider crab campaigns are carried out in Argentina

It is intended to be able to estimate the biomass, abundance, distribution, areas of concentration and population structure of said species north of parallel 41º South. The abundance of the main demersal resources between 50 and 300 meters of depth will also be estimated. Gustavo Colombo will be the scientific responsible for the Argentine part and has set, as secondary objectives of the cruise, to determine the structure of lengths and ages of common hake north of 41 ° South, to verify the spring closed area for juveniles and to study the composition , distribution and abundance of the macrozooplankton community to identify areas with high availability of prey for juveniles and adults of hake.
