Tridge summary

The National Institute for Fisheries Development Research (INIDEP) has initiated a comprehensive 16-day survey of shrimp in the San Jorge Gulf, national waters, and the Chubut coast. Conducted by scientific chief Emiliano Pisani and a team on the Second Commercial Lobster Fishing Vessel, the survey aims to document shrimp concentrations, analyze the spatial distribution of mature and impregnated females, and estimate fertility indices. The research also focuses on the composition and abundance of the epi-benthic fauna, by-catch quantification and sampling, and the characterization of zooplankton. The findings will be crucial in monitoring the shrimp population and predicting the upcoming fishing season.

The National Institute for Fisheries Development Research (INIDEP) launched on Friday, March 24, the survey of shrimp in the San Jorge Gulf, national waters and the Chubut coast, with Lic. Emiliano Pisani as scientific chief and on board the Vessel Second Commercial Lobster Fishing Vessel. The campaign, which is expected to last 16 days considering bad weather, aims to verify the presence of concentrations of shrimp accessible and vulnerable to the commercial beam net in the areas between parallels 43º 10 S and 47º S and to the west of the longitude 063º 50' W; analyze the spatial distribution of mature females and impregnated females; estimate fertility and ovarian maturation indices; determine the composition and abundance of the epi-benthic fauna associated with the main shrimp distribution funds in the evaluation area, among others. In addition, the quantification and sampling corresponding to the by-catch will be carried out; Zooplankton samples will be obtained with the ...
