Abstract

Fish is a major source of protein with high nutritional value for individuals. Cyprinus carpio (Gulfam) is the third most widely cultivated, contributing 9% of the total aquaculture production. The problem of pale coloring of common carp as well as less growth with the passage of time was solved with the help of dietary carotenoids “Canthaxanthin”. In the present experiment, canthaxanthin was given 2% of the average body weight of the fishes. Fingerlings were taken from Punjab Fish Hatchery Faisalabad, while experiment was held in Fisheries Farms, Department of Zoology, University of Agriculture, Faisalabad. Two glass aquaria having the capacity of 60 liters water, each having 15 fingerlings of Cyprinus carpio were used for experiment up to the period of 45 days. Glass aquaria was marked as a T0 and T1. T0 received basic feed while T1 received carotenoids “canthaxanthin”. Physico-chemical parameters were also measured. Weekly specific growth rate (SGR) in terms of body weight (g) and body length (cm) was measured. Survival rate and FCR were also measured. At the end of trial duration, red pigmentation was measured. All the data were subjected to statistical analysis using paired t-test. The results of this study illustrated that average (DO) for T0 was 3.95±0.16mg/l (Dissolved Oxygen) and for T1 was 3.98±0.11mg/l, average temperature was 26.36±0.41°C and 27.63±0.47°C and average pH was 7.36±0.12 and 7.51±0.12 for T0 and T1 respectively. Average gain in body weight for T0 was 0.99±0.09g specific growth rate (SGR) and for T1 was 1.67±0.22g (SGR). Average gain in body length for T0 was 0.79±0.06cm (SGR) and for T1 was 1.23±0.14cm (SGR). Average feed conversion ratio results for T0 and T1 were 20.70±2.84 (FCR) and 11.00±1.58 (FCR) respectively. Survival rate for T0 was 73.3% and for T1 was 86.6%. The average of red pigmentation was 1.03±0.06 for T0 and 2.40±0.30 for T1. Results showed that there are non-significant relationship among dissolved oxygen, temperature and ph. While, there are highly significant relationship among SGR, FCR, survival rate and pigmentation. So, these results prove that carotenoids have beneficial effects on fish growth and pigmentation.
