Floating Or Sinking Fish Feed Pellets
Commercial fish feed pellets can be divided into two types: floating type and traditional sinking type. Both types can reach satisfactory growth, but some fish species prefer floating type, while others prefer sinking type, both have pros and cons. The floating type has some advantages compared with the sinking type. As we have mentioned above, salmonellosis and bacterial infections can be killed during the pelletizing process, so it can reduce disease infections. The remains of sinking pellets at the bottom of the tank will often go rot while floating type can retain its shape for long hours, so floating fish feed pellets can reduce waste. Besides, farmers can observe the feeding intensity and adjust feeding rates accordingly with floating fish feed pellets.
