Nutrients for fish are contained in Commercial and Aquarium fish feed as well as live feed like Black Soldier Fly- larvae and Prepupae. To ensure fast growth and good fish harvest a well-balanced nutrition according to the needs of the keptfish species is important
Macro Nutrients[]
- Amino acids are the basic components of proteins. An example of an aquatic diet that is a good source of amino acid is a crumbled hard boiled egg offered to small fry.
- Fats that are broken down into fatty acids are the main source of energy in fish especially for the heart and skeletal muscles. Fats also assists in vitamin absorption. Vitamins A, D, E and K are fat-soluble or can only be digested, absorbed, and transported in conjunction with fats.
- Carbohydrates are molecular substances that include sugars, starches, gums and celluloses. Most of the carbohydrates that are incorporated into aquatic diets are of plant origin and are sources of the enzyme amylase. Carbohydrates, however, are not a superior energy source for fish over protein or fat but digestible carbohydrates do spare protein for tissue building. Unlike in mammals, glycogen is not a significant storage depot of energy in fish.
