Short summary
Carp is one of the most important fish in aquaculture. For future breeding programs, precise phenotyping is required. CT technology has been used to predict body composition in mirror carps. Back fat has proven to be a suitable parameter for predicting the fillet fat content. The volume calculation of back fat provides better results than a two-dimensional thickness measurement of back fat. The fillet yield can be predicted with moderate results by CT-based thickness measurements of the fillet.
