Feeding habits, diel periodicity and total daily ingestion, and nitrogen budgets of longfin dace (Agosia chrysogaster) were examined on two occasions when food quality, but not quantity, differed. Agosia chrysogaster was found to be an opportunistic omnivore, consuming primarily insects when the preferred taxon (baetid mayflies) was abundant in the environment, but consuming primarily algae when mayfly abundance was low. Ingestion provided a better measure of diel feeding periodicity than gut… CONTINUE READING
