This experiment was conducted with 600 (Oreochromisniloticus) fingerlings with an average body weight 10+ 1 g. The fishwere transported alive for 2 hours under different treatments,acriflavin at concentration 1 mg/l, MS 222 at concentration 30 mg/l,NaCI at concentration 10 gm/l, crushed ice, compressed oxygen andwithout treatment from El-Abbasa Fish Farm, El-Sharkia Governorateto Fish Research Center, Suez Canal University -Ismailia Governorateusing large polyethylene bags.Upon completion of transportation. The fish under eachtreatment were separately stocked in aquaria having fresh water ofgood quality and allowed to recover for 20 days.The results demonstrated that the mortality percent duringtransportation among fish transported under acriflavin, MS222, NaCI,crushed ice, compressed oxygen and without treatment were 8%, 6%,0.0%, 0.0%, 25% and 40% respectively. While the total mortalitypercent after 20 days reached 30%,34%,12%,22%,40 % and 65%respectively and the morbidity rate were 30% , 30/0, 0.0% , 20/0 , 10%and 20% respectively.The clinical signs of the diseased fish after transport weredetachment of scales, fry fins and tail, aggregation of fish at watersurface, excessive mucus secretion.
