Using Statistical Analysis to Assess the Effects of Feeding Pellets on Fish Dietary Preferences in an Intensive Polyculture System

Abstract

The paper proposes a statistical method for assessing the impact of multiple nutritional recipes on fish growth, raised in polyculture systems, a useful tool in selecting diets within small and medium-sized farms. After designing an experimental installation that produces pelletized feed, the study investigated the associations dependent on the feeder composition for three fish species involved in the experiment (Cyprinus carpio, Hypophthalmichthys nobilis and Carassius carassius). The fish relative mass and size variations have been used as performance parameters. The authors also issued hypotheses on the relations created between the studied species and determined the Feed Conversion Ratio.
