Effects of pH on the rate of aggressive display for mirror image reinforcement in Siamese fighting fish (Betta splendens)
Aggressive Behavior, 1 (3): 213--215 (1975)
Abstract
Studied an hypothesis suggesting that fluctuations in hydrogen ion (pH) intensity may suppress the rate of aggressive display in Siamese fighting fish. The effect of pH upon the rate of ring swimming for aggression-releasing mirror image presentation was investigated in 4 male fish under pH intensities of 5.0, 7.0, and 9.0 in a steady-state design. Results indicate no significant variation in the rate of response over pH levels. Two possible mechanisms of pH resistance are discussed. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
