Title

Minimum inhibitory concentration, lethal and optimal doses of sodium chloride on fungal infections of Persian sturgeon (Acipenser persicus) larvae and eggs

Abstract

 One of the most important problems in hatcheries is Saprolegniasis. It can be cause of high mortality of eggs and reduce the efficiency of hatching. The objective of the present study was to determine the optimum level and effective exposure time of sodium chloride on fungal infection of Persian sturgeon eggs (Acipenser persicus). The study was conducted in three different time durations: early of April, late of April and early of May and at five different concentrations (1, 1. 5, 2, 2. 5 and 3%) and four various time exposures (15, 30, 45 and 60 min). Results indicated that eggs and larvae of Persian sturgeon were died when exposed to concentration of 3% at all exposure times. The level of 2. 5% sodium chloride was effective to control fungal infections but the newly-hatched larvae could not swim, implicating the negative effect of sodium chloride on Persian sturgeon embryo at the applied concentration. Amongst other concentrations of 1, 1. 5 and 2%, there was no significant different between the control and 1% sodium chloride (P>0. 05). Furthermore, no significant difference was observed between concentrations of 1. 5 and 2% (P>0. 05). Level of 2% sodium chloride at time exposure of 15 min showed the highest rate of efficiency and the lowest fungal infection rate. Amongst concentrations, larvae hatched mostly when exposed to concentration of 2% sodium chloride solution for 15 min.
