The study assessed the impact of salinity and fungal incidence on the growth of red tilapia fingerlings (Oreochromis mossambicus x Oreochromis niloticus). The experiment lasted for 35 days and took place in 40 L polypropylene tanks. Fingerlings were individually counted, weighed, and randomly distributed among three equal treatments with 25 fingerlings each. T1 had 0 ppm salinity (freshwater), T2 had 15 ppm salinity, and T3 had 30 ppm salinity. Variables measured included weight gain, average weight, absolute growth, specific growth, survival, feed consumption, feed conversion, fungal incidence, and water parameters. At the end, T3 exhibited superior performance (average weight, feed consumption, and fungal incidence), statistically identical to T2. T1 showed a higher feed conversion and elevated water parameter levels. No statistically significant differences were observed in specific growth and survival among treatments. It was concluded that T3 (30 ppm) did not negatively impact productive parameters or water parameters. |
