Commercial fish diets can be classified into floating (extruded) or traditional sinking (pressure-pelleted) pellets. Both floating and sinking feed can produce satisfactory growth, but some fish species prefer floating, others sinking. Now that, which is a better type of fish feed pellets? To sink or to float? That is a question. Before I start, I would like to make a statement that neither can be considered absolutely superior compared to the other and your choice of whether to use floating or sinking pellets mainly depends on which type of fish species you have.
There are both pros and cons both to the two types of pellets. However, the use of floating pellets provides more advantages compared to sinking ones:
1. Reduce Waste.
Sinking pellets that remain at the bottom of the tank will often get lost and wasted. However, the floating feed pellets can retain their shape, even after being in the water for many hours, uneaten feed is still intact.
2. Decrease Disease.
Sinking pellets that remain at the bottom of the tank will eventually rot, which may give rise to a proliferation of bacteria and the spreading of harmful fish disease.
3. Convenient Observation.
Another reason to feed floating (extruded) pellets is that the farmers can directly observe the feeding intensity of their fish and adjust feeding rates accordingly. Determining whether feeding rates are too low or too high is important in maximizing fish growth and feed use efficiency. However, sinking pellets will fall into the bottom of the tank, even fish can not find them.
For all these reasons, floating fish feed pellets have recently become readily available in quantities that may make their use more feasible. Any questions, please feel free to contact us.
