Results on Argentine (Argentina spp.), Bluemouth (Helicolenus dactylopterus), Greater forkbeard (Phycis blennoides) and Spanish ling (Molva macrophthalma) from 2012 Porcupine Bank (NE Atlantic) survey

Abstract

This paper presents the results on four of the mostimportant deep fish species of the last Porcupine Spanish survey carried in 2012, and updates the documents presented in previous years with the information on the eleven years (2001-2011) of the Porcupine Spanish bottom trawl surveys on the Porcupine Bank. The document presents total abundances in weight, length frequencies and geographical distributions for Argentina spp. (mostly A. silus, results on proportions by Argentina species distribution in last surveys are provided),bluemouth, greater fork-beard and Spanish ling. All species considered present increases in their abundances, that are especially remarkable in the case of greater forkbeard and Spanish ling, confirming the good recruitments detected in 2011 survey. Besides both species have shown new recruitment peaks in 2012 survey.
