The Effect of Temperature and Diet on the Degrees of Specific Growth Rate Percentage (SGR %) and Weight Growth (WG %) of Angel Fish Fry (Pterophyllum scalare)

Abstract: There are several factors affecting Angel Fish fry’s (Pterophllum scalare) growth and quality. In this study, the effect of food treatments including dry blood worm, Artemia decapsulated cysts and dry blood worm together with Artemia decapsulated cyst in three temperature conditions i.e., 27, 29 and 31°C on specific growth rate and weight growth of angel fish fry (Pterophllum scalare) has been studied. For each food diet three repetitions took place. Thus, 27 aquariums with 30, 40 and 60 dimensions were allocated to the treatments. An observant treatment with 28°C and pollaki as the food was also used. The degrees of these indexes (SGR and WG) were examined in a 6 month experiment. Meanwhile, the other factors including the pH and the oxygen degree were fixed and similar for all treatments. The results showed that the temperature and food type are simultaneously effective on specific growth rate and weight growth of the fish. Among all food and temperature treatments and the observant treatment, the degree of SGR and WG for the fish was believe to be more in the food treatment with 31°C and powdered dry blood worm. This result confirms that temperature and food diet simultaneously affect the Angel Fish fry’s SGR and WG.
