Development of fish feed Pelleting technology and performance evaluation

Abstract

In developing country, the scarcity of protein causes human disability and different causes of diseases. Animal feeds account for a larger portion of the cost of livestock production. However, Fish is excellent source of protein. You can get the essential protein that human body needs by including fish in your diet. The challenge in Ethiopia was no technology to prepare the fish feed and currently high demands from fish customers. The development of fish feeding extrusion die can increase fish production through the development of dies to improve the capacity of pelleting and floating time. The die where evaluated using wheat, maize, nuts, cake and frushika ingredients with three replications and a completely randomized design. The maximum floating time was 6.34 hours, and minimum was 5.37 hours at a moisture content of 20% and 30%. The mixing ingredients, Frushika (75%), and Nug Kacke (25%), were combined and pelleted at a moisture content of 35 %. The highest pelleting rate attained was 16.45 kg/h. The maximum floating time of 10.48 hours was produced at 3.26 mm in diameter product buffering. With a minimum pelleting capacity of 11.85 kg/hr and a moisture content of 35% and a buffering diameter of 2.93 mm, the maximum floating time was 10.16 hours. To increase the economical level, fish producers can feed pelleting technology, which can increase fish production.
