Abstract

The purpose of this research is to study the effect of substitution of fish meal with silage meal of chicken feathers on feed to protein digestibility, growth and survival rate of striped catfish (Pangasius hypopthalmus). The test fish used is catfish with an average weight of 2.31 ± 0.04 grams /fish. This research used experimental method with Completely Randomized Design, 5 treatments in triplicate. The treatments in this study were substitution of fish meal meal with different dose of chicken feather meal, namely A, B, C, D and E (0%; 25%; 50%; 75% and 100% silage meal of chicken feathers, respectively). Parameters observed included relative growth rate (RGR), feed conversion ratio (FCR), protein efficiency ratio (PER), Apparent Digestibility Coefficient of Protein (ADCP), and survival rate (SR) of catfish. The results showed that the substitution of fish meal with chicken feather silage meal was very significant (P <0.01) to RGR, FCR, PER, and ADCP, but no significant effect (P> 0.05) on SR of catfish. Dose 25% silage chicken feather meal in the feed is the best dose to improve the RGR and ADCP of catfish. Water quality during the study is still within a reasonable range for catfish culture.

Highlights

Striped catfish (Pangasius hypopthalmus) is one of the fish commodities that have high economic value both as a consumption fish and ornamental fish
The high value of relative growth rate (RGR) of catfish fed B is presumed to be the right diet for catfish in utilizing the essential amino acids contained in the diet so that the diet has an apparent digestibility coefficient of protein (ADCP), the feed conversion ratio (FCR) and the highest protein efficiency ratio (PER) (75.59%, 1.53 and 2.59, respectively) that support growth
This opinion is supported by Somsueb and Boonyaratpalin (2001) which states that diet with 100% silage meal chicken feathers will appear smells that affect the palatability of fish

Summary

Introduction

Striped catfish (Pangasius hypopthalmus) is one of the fish commodities that have high economic value both as a consumption fish and ornamental fish. Intensive cultivation of the catfish is very dependent on the existence of artificial diet quality. The quality of diet is determined by the protein content. Protein is an important nutrient in diet both the quality and quantity of protein is very important for fish growth from seed size to consumption (Suloma et al, 2014). Fish meal in artificial diet to date is used as a source of animal protein. The use of fish meal in the diet has the main problems of rising costs, uncertain availability, counterfeiting and quality variations. With the increasing demand for unstable fish meal stocks and high fish diet prices, and with the expansion of cultivation activities, it is necessary to look for alternative sources of protein (FAO, 2013)
