Shrimp assessment survey concluded

The objective of the survey was to analyze the spatial distribution of mature females and impregnated females in order to estimate fertility indexes, ovarian maturation and early maturity. Likewise, Patagonian shrimp egg and larvae would be located from zooplankton samples.

Shrimp (Pleoticus muelleri) assessment survey in the Gulf of San Jorge and the coast of Chubut concluded on March 23, when the commercial vessel Bogavante Segundo, belonging to Iberconsa, arrived in Puerto Madryn.

In 15 days’ work, eight researchers from the National Institute of Fisheries Research and Development (INIDEP) together with two officials from the province of Chubut and the crew of the vessel, were able to verify the presence of concentrations of accessible and vulnerable shrimp to the commercial shrimp network in the areas between latitude 43° 00' S and 45° 00' S, west of 064° 00' W; and between latitude 45° 00' S and 47° 10' S, west of 065° 00' W.

"We were able to fulfill all the objectives proposed for the survey", emphasized the scientific chief M.Sc. Juan de la Garza, a member of the Fisheries Program of Bentho-demersal Crustaceans.

In turn, the scientist appreciated the efforts of the crew of the vessel Bogavante Segundo, who collaborated "at all times" and helped them to carry out all the scheduled work.

The objective of the survey was to analyze the spatial distribution of mature females and impregnated females in order to estimate fertility indexes, ovarian maturation and early maturity. Likewise, Patagonian shrimp egg and larvae would be located from zooplankton samples.

It is also intended to determine the oceanographic variables and the composition and abundance of the epi-benthic fauna associated with the main distribution funds of the shrimp in the evaluation area.

Researchers are already working on the report of the shrimp recruitment survey, which will then be submitted to the Federal Fisheries Council.
