Effects of Eucalyptus Essence, Malachite Green and Sodium Chloride on Hatching Rate of Persian Sturgeon (Acipenser persicus) Eggs
Journal Title: Journal of Veterinary Advances - Year 2012, Vol 2, Issue 10
Abstract
This study investigation on the effects of Eucalyptus essence, Malachite green and sodium chloride treatments on the hatching success of Acipenser persicus eggs. Eggs were artificially fertilized, 50 counted and transfered to a static bath dip treatment in given concentrations of Eucalyptus essence Malachite green and sodium chloride for 15, 30 or 60-minute durations after 24h being incubated at 19 ± 1°C. Treatment efficacy was assessed by comparing the percent egg hatch in the treatment group to the untreated control group. Eggs treated with Eucalyptus essence at 200ppm Malachite green at 5ppm and sodium chloride at 2% recorded greater mean percent hatching compared to the controls. The highest mean percent hatching recorded in this study was in eggs treated by 200 ppm Eucalyptus essence in 60 min (up to 95% survival). Although sodium chloride gave the best performance, on the basis of safety concerns, ease of availability and cost. We recommend 2% sodium chloride treatment of A. persicus eggs for routine use by hatchery fish farmers to improve A. persicus eggs hatchability.
