The activity of lactate dehydrogenase in the teleost Oryzias latipes , shows a gradual increase during embryonic development, followed by an abrupt rise on hatching, which coincides with the appearance of the retinal isoenzymes. By the time of hatching, the retina has differentiated, and no significant change is observed in the retinal structure until 2 days after hatching. It was assumed that metabolic changes which occur on hatching may trigger the synthesis of retinal lactate dehydrogenase isoenzymes.
