Fish feed for tilapia
Formulated or compounded feed can be supplied to tilapia in a dry, moist or wet form. Dry mixed feed can be presented to tilapia fish in the form of powder, pellets or crumbles. The most popular is the feed pellets, whose shape and size depend on the age of the tilapia.
Commercial fish feed pellets are generally produced into extruded feed or pellet feed. Floating and sinking feed particles can produce satisfactory growth for fish, but some fish prefer floating feed, while others prefer sinking feed. Floating fish feed pellets are ideal for tilapia, which feed from the surface of water.
Because of the high manufacturing costs, the extruded feed pellets are more expensive. In general, it is advantageous to feed floating squeeze feed, as farmers can directly observe the feeding strength of their fish and adjust the feeding speed accordingly. Determining that feeding speeds are too low or too high is essential to maximize fish growth and feed efficiency. With the fish feed extruder, you can easily make floating fish feed pellets from a less expensive, common material.
Feed sits in a variety of sizes, from fine crumbles for small tilapia to large (1/2 inch or larger) granulated. The pellet size should be about 20% to 30% of the diameter of the tilapia. Too small feeding particles can lead to inefficient feeding because more feed pellets need to be found and eaten. Instead, pellets that are too large suppress feed and, in extreme cases, cause suffocation. Choosing the right particle size will promote active eating of tilapia
Tilapia fish feed formulation:
Low-cost tilapia fish feed, prepared from locally available raw materials, should be nutritionally comparable to high-quality tilapia fish feed to maintain productivity.
The preparation of fish feed in small farms requires a lot of labor, and the lack of amino acids in certain ingredients can damage the quality of the feed.
Commercial tilapia feeds are formulated, cooked, extruded and pelletized diets typically containing 32 – 40% protein. This can be fishmeal or soy protein, which is more suitable for tilapia fish.
Floating pellets are generally recommended as they remain on the surface until they are consumed. They are more expensive. Sinking pellets are easier to make and cheaper, but they can get lost in the mud at the bottom of the pond. This is not a problem in shallower artificial containers, and the fish will find pellets that sink to the bottom of the tank.
Tilapia fish also eat plants, usually algae. Duckweed can be used with commercial fish feed to increase protein levels in its diet.
The formula feed for tilapia should contain 27% to 40% protein. For fry and fingerlings, there should be small particles in the feed, the protein content should be 35% to 40%, and for adults, the protein content should be between 27% and 30%.
Some farm-made feeds can have the following combinations:
Powdered Leucaena leaves 20%
Cooked maize 80%
Rice bran 70%
Palm Kernel Cake 15%
Maize meal/Cassava Dough 15%
