PAKAN APUNG ARTIFASIAL UNTUK BUDIDAYA IKAN LELE PENGARUH PENGAPUNGAN PAKAN TERHADAP PERTUMBUHAN IKAN LELE DENGAN METODE PENGUKURAN FCR (FEED CONVERSION RATIO)

Abstract

Catfish is a fish that consumed by many people in Indonesia, a relatively high nutrient content and relatively inexpensive price of catfish are the reasons why catfish become people's choice. Thus, the need of catfish grows continuosly in every area, it is directly proportional to the increasing demand for catfish feed. To improve the quality of livestock products, especially catfish fishing, artificial floating feed manufacturing is an option that is expected to help the government to solve the problem. In this research will be carried out experiments to obtain the ideal feed composition as a reference artificial floating feed making. Variable composition of fine bran in this study is 20%, 22%, 24%, 26%, and 28%. While the observation of weight gain of catfish by the method of FCR (Feed Conversion Ratio) is done by a basket of catfish weighed in at once and then taken catfish weight average rating, catfish weighing performed at the age of multiples of 7 days to harvest. As for the observation that the amount of feed consumed was also done weekly until it is possible catfish ready for harvest. Data obtained results is that the composition in the manufacture of ideal artificial feed is 24% fine bran, 40% fish meal (chicken feather meal) and 36% starch. Of this composition, artificial floating feed is able to float for 15 minutes. Economic analysis of the data obtained that the use of a combination of artificial feed and feed from the company with NAIC is more profitable than the use of feed from the company entirely without the NAIC is gained 21.7%. But for the future, farmers are advised to use catfish artificial feed entirely due to the benefits which can be increased to 35.8%.
