Abstract

An affordable feed for the growth of African catfish (Clarias gariepinus) juveniles was developed in Benin as an alternative to high-cost imported feed. Initially, locally available fish feed ingredients were inventoried. Subsequently, six feed formulas (Feeds 1 to 6) were developed using linear algebra software, and the feeds were pelleted using a locally built extruder. The protein content of the formulated feeds ranged from 366 to 405 g kg-1, fat content from 84 to 111 g kg-1, and carbohydrate content from 239 to 330 g kg-1. Among the formulations, Feed 1 (protein: 390 g kg-1, fat: 84 g kg-1, carbohydrates: 330 g kg-1) closely matched the nutritional composition of the imported feed (protein: 424 g kg-1, fat: 84 g kg-1, carbohydrates: 346 g kg-1) commonly used by most fish farmers in Benin for catfish. Additionally, it had the lowest ingredient cost (0.46 US$ kg-1). Following this, the growth of C. gariepinus fingerlings was evaluated when fed with Feed 1 in a 56-day exploratory trial. The weight gain, feed intake, and protein intake of fish fed with Feed 1 were significantly lower (p = 0.000 for each parameter) than those fed with the control feed. However, Feed 1 exhibited a good Feed Conversion Ratio (1.25) and an acceptable protein efficiency ratio (2.05).
