Abstract:

 Gambusia holbrooki; tolerance; salinity; temperature; pH; LC50have been studied in the laboratory.Serial concentrations of salinity, 0.8, 5, 10, 15, 20, 25, 30, 35 and 40 ‰ were prepared by dissolvingNa Cl in water. All fish were died at 20 ‰, so serial concentrations of 15, 16, 17. 18. 19 and20 ‰ were tested to determine the LC50. Lower temperatures were conducted at 3, 4, 5, and 6 0C,while upper temperatures were conducted at 31, 32, 33, 34, 35, 36, 37, 38 and 39 0C to determine theLC50. pH values were prepared at 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13 to determine the LC50. Thisstudy showed that G. holbrooki off drainage of Domat Al-Jandal Lake, KSA can tolerate abruptchanges in salinity, temperature and pH changes. The LC50 of salinity was 16 ‰. LC50 of lower andupper temperature on G. holbrooki were 3.5 and 36.5 0C when transferred abruptly from 22 0C. TheLC50 of pH in acidity and alkalinity range were 3.5 and 11.5 respectively. From this study, it can beconcluded that G. holbrooki can be used under different conditions of 15 ‰ salinity, range of pH from4 to 11 and range of temperature from 4 to 35 0C for controlling mosquito if transferred abruptlywithout acclimatization .
