The gills of Periophthalmus chrysospilos exhibited significantly greater pyruvate kinase and lactate dehydrogenase activities than those of Boleophthalmus boddaerti ( P <0.01). Under the control normoxic condition, the branchial lactate content of the former mudskipper was also significantly greater ( P < 0.01) than that of the latter. After hypoxic exposure, lactate and alanine accumulated in the gills of P. chrysospilos but not B. boddaerti . Succinate and propionate were not detected in the gills of these two mudskippers under the control and hypoxic conditions.
