abstract
Nucleic acid content in different tissues in the male freshwater fish N. notopterus were studied during 2011-12,2012-13,2013-14 for 3 years Pre-spawning phase of the reproductive cycle. The fishes were scarified and the tissues such as brain, liver, kidney and the gonads (testis) removed and processed for determination of nucleic acids. The present results showing testis has higher in comparison to other tissues testis>liver>brain>kidney. Nucleic acid contents gradually increased from Pre-spawning to spawning phase in most of the tissues. The increase may be because of increasing gonadal activity for spermatogesis in male fish.
