Abstract

Diel plasma melatonin levels were measured to determine the effects of varied light intensities in juvenile and adult rainbow trout. This study showed that night-time melatonin plasma concentrations were significantly higher (P < 0.05) in juveniles (600±75 pg/mL to 492±29pg/mL) than broodstock (314±83pg/mL to 265±55pg/mL) at 1250 lux. Light intensities of 700 lux were unresponsive in both groups. This amplitudinal difference between juvenile and adult fishes response to light may suggest a developmental importance of melatonin. © 2004 Kluwer Academic Publishers.
