Development and Evaluation of a Volumetric Quantification Method for Fecal Particle Size Classification in Rainbow Trout Fed Different Diets

Alternative plant protein sources, such as soybean meal, can interfere with digestion due to the presence of anti‐nutritional factors that cause a diarrhea‐like condition in Rainbow Trout Oncorhynchus mykiss , resulting in very fine fecal particles that can adversely affect aquaculture systems and the environment. More research is needed to examine the impacts of feed formulation changes on fecal quality. The prevailing method (laser...
