Argentine-Uruguayan joint evaluation campaign on anchovy

In recent days, the BIP Víctor Angelescu of INIDEP began a new joint Argentine-Uruguayan evaluation campaign of northern anchovy cash in the spring. The area to be investigated includes the parallels of 34 ° and 41 ° 45 ′ South, from the coast to almost 100 meters deep, in the sector up to the parallel of 37 ° 30 'South, as specified by the Institute in the announcement of the launch of the campaign. The main objectives of the campaign headed by the Pelagic Fish Fisheries Program of the organism, are to estimate the biomass of the population under study by hydroacoustic methods and by the Daily Egg Production Method (MPDH). An attempt will also be made to obtain indices of the composition of the population by length and age classes corresponding to each stratum and the total area, as well as vital parameters such as growth, mortality, length at first maturity. In addition, the researchers will seek to characterize the acoustic response of the anchovy and its accompanying fauna by ...
