| Summary, etc. |
A field study was conducted in two tilapia hatcheries, hatchery (A) located at El Fayoum Governorate and hatchery (B) located in Sharkeya Governorate, to investigate the effect of water quality on seed production. Eighty-four water samples were collected from the inlet, outlet, broodstock ponds, egg funnels and nursery ponds for determination of physico-chemical condition and microbial count of water used for incubating eggs and nursing frys. Fry and eggs samples were also examined for microbial loads. The following study was also designed to assess the effect of using Iodophors 3.5 %on hatchability % and microbial load of tilapia eggs and to evaluate the effect of using different disinfectants on different tools used in the hatchery for reducing pathogens number.Results of the field study indicated that there was no significant difference between both hatcheries with respect to microbial counts of water samples, fry and eggs, although they were slightly higher in hatchery (B) than hatchery (A). Temperature (Temp.) and pH were not significantly different among water samples from both hatcheries. Dissolved oxygen (DO) and nitrite were significantly different for water samples used for incubating eggs recording (5.11 ± 0.305), (4.80 ± 0.44) mg/dl, respectively in hatchery (A) and (0.06 ± 0.03), (0.09 ± 0.06) mg/dl, respectively in hatchery (B). DO and nitrite were also significantly different for water used for rearing fry with means of (4.84 ± 0.24), (5.11 ± 0.47) mg/dl, respectively in hatchery (A) and (0.08 ± 0.05)and (0.11 ± 0.10) mg/dl, respectively in hatchery (B). Ammonia showed significant different P < 0.05 between both hatcheries for water samples used for incubating eggs with means of (0.23 ± 0.09)and (0.72 ± 0.35) mg/dl, respectively, while ammonia in water samples used for rearing fry were not significantly different between both hatcheries. The low level of difference in both microbiological and physico-chemical parameters between the two hatcheries didn't affect fertility, hatchability and mortality% as it recorded95%, 90% and 10 % respectively in hatchery B and 96%, 91%, 9 % respectively in hatchery A. The better performance of hatchery (A) may be due to better sanitary measurements adopted |
