Abstract
This study aimed to assess how salinity and temperature affect the growth productivity, survival rate, and feed conversion rate of Thai-Pangas (P. hypophthalmus) fingerlings. The fingerlings were raised in laboratory conditions for 63 days, subject to varying salinity levels of 0, 4, 7, 10, and 13 ppt, and temperatures of 24, 27, 30, 32, and 34 °C. The results showed that the fingerlings exhibited high mortality (100%) within six hours when exposed to 13 ppt salinity, while 62.5% mortality occurred at 13 ppt salinity. No deaths were observed in other treatment groups. At 30 and 32 °C with salinities of 0, 4, and 10 ppt, significantly higher specific growth rates were observed compared to 13 ppt salinity. There were no significant differences in the feed conversion rate and proximal composition among the treatment groups. The study concluded that Thai-Pangas fingerlings are suitable for salinities up to 10 ppt and water temperatures of 32 °C, with satisfactory growth rates. The species showed better adaptation to temperatures between 27 and 30 °C, while high temperatures of 34 °C and low temperatures of 24 °C were found to be stressful and unsuitable for thriving.
