Abstract
Distribution of adenine nucleotides (ATP, ADP and AMP) and energy charge potential were studied in 4 different regions of the brain of 9 various fish spp. [Labeo rohita, Cirrihina mrigala, Catla catla, Heteropneustes fossilis, Clarias batrachus, Mystus seenghala, Ophicephalus striatus, O. punctatus and O. marulius]. The cerebellum contained the highest amounts of ATP, ADP and total adenine nucleotides; the lowest values were detected in the medulla oblongata. No statistically significant differences existed in the distribution of AMP, although its concentration was usually highest in the medulla oblongata. The snake-headed fishes had the highest amounts of ATP, ADP and AMP in the brain. These differences in the distribution of adenine nucleotides are probably due to differences in phylogeny and account for the variable degree of oxidative processes, particularly oxidative phosphorylation, in various parts of the brain.
