Description
Summary:The changes appreciated in the distribution of American plaice (Hippoglossoides platessoides) by depth on the Grand Bank (NAFO Divisions 3NO) in the period 2001-04 did not show a clear relationship with the increase of estimated biomass. Significant differences in the distribution depth range between sizes and sexes were observed. The females were distributed until deeper than the males. The small individuals (<20 cm) also appeared in the deepest strata. Inter-annual changes were appreciated in the period 2001-04 with an accused decrease in the distribution depth range in the 2004. The population was concentrated at shallower depth in spite of the increment of the abundance and biomass in the last year.
