“…During the past decade scientists have started to examine the ecological role of these abundant organisms in an effort to take a more integrated ecosystem approach to fisheries management (Lovrich & Thiel, ). Diez, Cabreira, Madirolas, and Lovrich () have more recently noted that between 2009 and 2014 pelagic swarms of Mu. gregaria increased their occurrence and abundance in both the Beagle Channel and on the Argentine Patagonian Shelf.…”

“…In accordance with our results, an increase in Mu. gregaria swarms and benthic aggregations occurred in southern areas of the SJG (Diez, Cabreira et al., ; Roux & Piñero, ), probably driven by natural population growth in the absence of high predation‐related mortality, coupled with oceanographic factors. Both aspects are discussed below.…”

“…These species fulfill several criteria to be considered WW species, including: (1) they are species with high regional abundances (Madirolas et al 2000, Padovani et al 2012, Arkhipkin & Laptikhovsky 2013, (2) they seem to occupy low to mid-trophic positions (TPs) in food webs (Ciancio et al 2008, Riccialdelli et al 2010), (3) many predators feed on them (Raya Rey et al 2007, Riccialdelli et al 2010, Scioscia et al 2014, and (4) the population dynamics of these species appear to depend on the environment (e.g. climatic variations) (Diez et al 2016(Diez et al , 2018. There is a need for better identification of WW species as an essential functional trophic group to improve food-web models, but particularly for conservation purposes.…”

“…This is similar to the definition of TS where TS value is the result of the detection of a single organism, while SV is the value for detection organism groups in (Kaartvedt and Aksnes, 2012) To date research on fish stock estimates done by cruise track using a SIMRAD EK 60 Scientific split beam echo sounder system with a frequency of 70 kHz and acoustic data acquisition is performed continuously during the day and night during the period boat cruise at speeds ranging between 7-8 knots. Trails include a data acquisition area of an area that allows the analysis of spatially made with the zig-zag shape according to (MacLennan and Simmonds, 1992in (Diez et al, 2016, Jurvelius et al, 2016 with the length of each transect approximately 12 nmi of bounds islands outwards.
