Ecological trend on demersal community in the Southern Grand Banks (NAFO Div. 3NO) from the Spanish Surveys: 2002-2011
Some ecological indices were calculated from the data obtained in the research surveys conducted by Spain in NAFO divisions 3NO between the years 2002 and 2011. These indices were calculated for individual populations (intrinsic population rate of growth and mean length) and for all the community (A...
