Abstract
Growth was studied in terms of the mean carapace length, wet and dry weight, protein, and lipid. Monthly length–weight regressions are presented for a 12-mo period. The growth of Thysanoessa spp. is closely related to phytoplankton production, while Meganyctiphanes norvegica (a carnivore) increases its weight continuously until it reaches its final size. In I-group Thysanoessa the individual maintains its body weight until midwinter, and this is followed by a continuous decrease in the body constituents until the onset of the spring phytoplankton bloom. The growth patterns are correlated with the environmental factors.
