Temperature changes influenced the growth performance and physiological functions of Thai pangas Pangasianodon hypophthalmus

Temperature is an important environmental factor that plays significant role in the growth and metabolism of fish. Hence an experiment was conducted to know the effects of temperature changes on growth, blood glucose and hemoglobin levels in Thai pangas, Pangasianodon hypophthalmus after acclimatized to four temperature conditions, such as 24 °C, 28 °C, 32 °C and 36 °C for 28 days. In addition, erythrocytic cellular abnormalities (ECA) and erythrocytic nuclear abnormalities (ENA) tests were assayed using peripheral erythrocytes after exposed to four temperature conditions. Fish were sacrificed at day -7, -14 and -28. Growth performance viz., weight gain, specific growth rate (SGR) and feed conversion ratio (FCR) were much better in 28 °C and 32 °C compared to 24 °C…
