If you want healthy and happy fish then a high quality feed is important. Poor quality feed can easily and quickly go rancid or change in biological composition. This can cause issues with palatability, smells and most damaging of all disease. Diseases can quickly spread throughout your fish stocks and can be extremely difficult to contain without massive fish losses. Good feed will also give the ultimate benefit of fast and stable growth; giving you wonderful river monsters (pond, lake or dam in this case).
