Metabolic levels in dogfish gill tissue after zinc treatments

Abstract

Dogfish were subjected to acute (80 ppm/24 hours) and subacute (10 ppm/21 days) zinc treatments before measuring the ATP, glycogen, protein, and lactate levels.Acute treatment varies significantly the levels of all the metabolites tested while only protein content is significantly lower after subacute treatment.The results are discussed in relation to the hypoxia effect produced by the metal and the related responses of the fish.
