The study area is limited between latitudes 51 ° S and 53 ° S and longitudes 57 ° W and 62 ° W

Within the framework of the Scientific Subcommittee of the South Atlantic Fisheries Commission (CPAS), the National Institute for Fisheries Research and Development (INIDEP) initiated on Wednesday, on board the research vessel BIP Victor Angelescu, a joint scientific cruise to assess the Southern blue whiting (Micromesistius australis), with the participation of researchers from the United Kingdom.
Southern blue whiting (Micromesistius australis)
The study, called "Acoustic estimation of the biomass of the Southern blue whiting (Micromesistius australis) reproductive stock", will last approximately 20 days and the study area is limited between latitudes 51 ° S and 53 ° S and longitudes 57 ° W and 62 ° W. For Argentina, 14 researchers and technicians from INIDEP will participate, and two from the United Kingdom.

The main objectives of the scientific cruise are to estimate the abundance of the Southern blue whiting reproductive stock; improve knowledge of the reproductive and biological aspects of this species and verify the drift of the early stages of development (eggs and early larvae) in the area south of the San Carlos Strait (Falklands Sound).
Longtail hake or Hoki (Macruronus magellanicus)
Patagonian toothfish (Dissostichus eleginoides), Patagonian cod (Salilota australis) and Nototenia (Patagonotothen ramsayi)
Scientists will also work to identify the distribution and calculate the relative abundance of other fish species, such as longtail hake (Macruronus magellanicus), Patagonian toothfish (Dissostichus eleginoides), Patagonian cod (Salilota australis), Nototenia (Patagonotothen ramsayi); collect biological samples of different species of fish (length, weight, sex, stages of maturity); obtain environmental parameters (temperature, salinity, chlorophyll a) to prepare an oceanographic diagnosis of the research area and collect samples of benthos to analyze its composition.
