Abstract

1. 1. Development of the digestive enzyme complement corresponded with this species' carnivorous habits and a natural dietary shift at metamorphosis from larval pelagic zooplanktivory to benthic carnivory. 2. 2. During the first developmental stanza when the digestive tract was differentiating and the larvae were dependent on endogenous nutritional reserves, digestive enzyme concentrations were low. 3. 3. Initiation of gastric secretion (pepsin and acid) was concomitant with onset of exogenous feeding. 4. 4. Highest amylolytic and lipolytic activities were recorded from feeding larvae prior to their metamorphosis to juveniles.
