Compound feeds and cereals as potential tools for improved carp Cyprinus carpio production

Appropriate supplementary feeding is of increasing importance in common carp Cyprinus carpio pond aquaculture, not only with respect to production issues but also as a sustainable tool for maintaining environmental quality. We studied the effect of different supplementary feeding regimes (no supplem...
