The effect of Peruvian small-scale fisheries on sunfishes (Molidae).

abstract：:Morphological (growth, Fulton's condition factor), physiological (per cent dry mass, total lipid content) and behavioural (activity levels) response patterns of carp gudgeon Hypseleotris spp. were examined in response to food deprivation during a 56 day experiment. Considerable variability in the nature and magnitude ...
