Abstract

1. 1. N-Acetyltransferase (NAT), and melatonin were determined at 3-hour intervals in the optic lobe of the giant freshwater prawn, Macrobrachium rosenbergii de Man. 2. 2. A relatively high activity of NAT, compared to that in rat pineal, was found in the tissue. The enzyme did not show a significant diurnal rhythm although a slight suppressive level was detected at night. 3. 3. Melatonin level varied considerably and showed a peak during the day (1500 hr) and a nadir during the night (2400 hr). 4. 4. The results suggest that the optic lobe has certain biochemical activities similar to those found in pineal glands of vertebrates. © 1992.
