Pathological lesions of acute sodium chloride toxicity in common carp : case report

الملخص EN

Sodium chloride (NaCl) has a major impact on fish farming, as it used to disinfect fish and their eggs, in contrast using NaCl in high doses can cause life threatening toxicity with high mortalities in Cyprinus carpio.

We aimed in the current report to introduce for specialists in fish culturing and farmers a typical acute NaCl toxicity by presenting pathological lesions.

The histopathological lesions are composed of severe degenerative and necrotic changes in gill filaments with destruction in blood vessels and hyperplasia in secondary gill lamella.

In conclusion, using NaCl in high uncalculated doses can cause significant pathological changes that lead to 100% mortalities in Cyprinus carpio.
