%X A study was performed to determine to effect of salinities (20, 25, 28, 30, 32, 35 and 40 ppt) and temperatures (20, 24, 28, 30 and 32¡ãC) on the decapsulation of Artemia cyst. The dry Artemia cyst were hydrated up to 2 hrs in fresh water at (26 ¡À 1oC) temperature with a density 0.3 g/ 50 ml water. Saline water was prepared using salt (NaCl) and hatching rate of Artemia cyst was counted after 36 hours of incubation. Highest hatching rate (72.59 ¡À 5.03), (75.84 ¡À 3.67), (74.45 ¡À 0.83), (89.38 ¡À 0.96), (76.46 ¡À 4.63), (70.58 ¡À 9.51) and (69.17 ¡À 0.70)% were observed in 20, 25, 28, 30, 32, 35 and 40 ppt salinities at 32, 28, 28, 24, 24, 24, and 28¡ãC temperature, respectively. Lowest hatching rate (57.03 ¡À 3.67), (47.97 ¡À 8.06), (46.20 ¡À 8.17), (39.58 ¡À 10.12), (47.36 ¡À 7.04) (25.86 ¡À 8.10) and (20.57 ¡À 2.71) % were measured in 20, 25, 28, 30, 32, 35 and 40 ppt salinities at 30, 32, 32, 32, 32, 32 and 32¡ãC, respectively. The maximum hatching rate (89.38 ¡À 0.96)% was found in 30 ppt salinity at 24¡ãC temperature and minimum hatching rate (20.57 ¡À 2.71) % was observed in 40 ppt salinity at 32¡ãC temperature. Therefore, 30 ppt salinity and 24¦ÏC temperature could be the optimum salinity-temperature for Artemia cyst decapsulation. Bangladesh J. Zool. 46(2): 197-204, 2018
