Effect of feed additive (carrot) on early growth, survival rate and pigmentation of Lampam Jawa (Puntius gonionotus)

Abstract

Lampam jawa (puntius gonionotus) Javanese carp is from Indonesia and convenient to culture (Keith, 1978). This species is convenient to culture. The culture of Puntius gonionotus was carried out at the Freshwater Hatchery, University Malaysia Terengganu (UMT). The fish was prepared from Manir, Kuala Terengganu as local supplier. This study was conducted to evaluate the effects of different feed additives (percentage of carrot) on growth rate parameters such as specific growth rate (SGR), survival and pigmentation of lampam jawa, as well as determination of protein content of pellet and fish tissue in different treatments. The important water quality variables (pH, DO and temperature) were measured during the trial. Four treatments were used for this study and all fishes were fed with four different diets (Control, Diet I, Diet 2 and Diet 3) during 8 weeks period. The analysis of SGR indicated significant difference in growth of fish between all dietary groups (P<0.05). This study showed that Diet 3 (30% of carrot) was the best diet in growth improvement of Jampam jawa. Analysis of moisture, ash and lipid were not influenced the survival and growth of Puntius gonionotus. But, the percentage of crude protein content in tissue was higher in Diet 3. The ANOVA analysis showed a significant difference of crude protein in tissue from all dietary groups (P<00.5). Species of Puntius gonionotus did not respond to colour pigmentation
