| The objective of this work is to increase knowledge on the distribution and punctual density of both morphotypes of Munida gregaria in the San Jorge Gulf, Argentina. The data derived from the research cruise carried out on board of the FV Álvarez Entrena I in February 2011. Specimens of gregaria and subrugosa were caught in 37 and 73 of the 91 trawls performed, respectively. Out of the total of positive trawls, 17 were performed at depths lower than 55 m and the remaining 60 at deeper waters. The relative average abundance of both morphotypes increased significantly with regard to the two previous years (2009, 2010). M. gregaria subrugosa represented 66.4% and gregaria the remaining percentage. In the south sector of the gulf, where the highest punctual... |
