Abstract

The effects of quality and quantity of food and water quality (hardness) on growth parameters such as body length and weight were studied in the fry of ornamental fish, red swordtail, Xiphophorus helleri. The fry when fed on Artemia nauplii grew faster than fry fed on beef liver, 35 % protein diet (1 mm size), egg yolk and pasted maida. Artemia nauplii fed group showed 9 fold increase in growth rate compared to fry fed on egg yolk and pasted maida. There was no significant difference (P<0.05) in body length and weight of animals subjected to 3/1 and 2/1 meal frequency; however, they elicited significant difference when compared with 1/1, 1/2 and 1/3 meal frequency. Fry reared in 1018 ppm water hardness exhibited 6 times more growth in body weight than those reared in the lowest hardness of 76 ppm.
