Abstract
We studied the effect of different salinities on growth, lifespan and maturation time in the Artemia urmiana under laboratory condition. The experiments were done on the control group and 12 treatment groups. Experimental salinities ranged from 30 to 125gL-1. In growth experiments the mean body length of 10 individual Artemia from each treatment were measured in days 1, 5, 11 and 17 and results showed that in high salinities treatments (75,100 & 125ppt) compared at 30ppt were significantly different decrease in growth in A. urmiana (P<0.05). The present study confirms that maximum growth was observed at 30ppt (5.062±0.937mm) minimum growth in A. urmiana was observed at 75ppt (3.156±0.386mm). In lifespan experiments showed that, increasing the amount of salinity in cases lifespan was decreased and maturation time was late. Longest lifespan was observed at 75ppt (67.66±2.516 day) and shortest maturation time for A. urmiana after (27.66±1.527 day) was seen at 75ppt.
