Treatment of Cyprinus carpio L. and Clarias gariepinus (Burchell) embryos with formalin and malachite green : effect of concentration and length of treatment on their survival

Abstract

Malachite green and formalin were investigated as prophylactic dip treatments for developing embryos of Cyprinus carpio and Clarias gariepinus. Based on the findings, recommendations are made on the respective concentrations to be used and exposure periods to be followed for both formalin and malachite green for both fish species.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.
