[0002] Fish feed is food specifically formulated to provide nutrition and energy to fish. It is an important part of farming and managing fish, ensuring that fish have access to the nutrients they need for growth, reproduction and health. The type and formulation of fish feed varies depending on the type of fish, its stage of growth and the environment in which it is kept.

[0003] The main components of the prior art fish feed

[0004] Protein: Provides amino acids, which are the basis for fish growth and repair of body tissues. The main sources include fish meal, soybean meal, meat and bone meal, etc.

[0005] Fat: provides energy and helps absorb fat-soluble vitamins. Common sources include fish oil, vegetable oil, etc.

[0006] Carbohydrates: provide energy and act as a bulking agent in feed. Common carbohydrate sources include grains (such as corn, wheat) and plant powders (such as potato flour).

[0007] Vitamins: Maintain normal physiological functions and the immune system. Commonly added vitamins include vitamins A, D, E, K and B vitamins.

[0008] Minerals: Maintain the health of bones and teeth and support physiological functions. Mainly include calcium, phosphorus, sodium, potassium, magnesium, iron, zinc, etc.

[0009] Cellulose: Promotes digestive health. Although fish have a low demand for cellulose, an appropriate amount of cellulose can improve the digestion and absorption of feed.

[0010] Types of prior art fish feed

[0011] Pellets: A common form of fish feed that is easy to store and feed. Pellets can be either floating or sinking.

[0012] Flake feed: comes in flake form and is suitable for smaller fish or special feeding needs.

[0013] Extruded feed: Feed that has been extruded through heat processing has a higher digestibility and nutrient utilization rate.

[0014] Liquid feed: usually used to supplement special nutrients or medicines and is suitable for specific breeding environments or fish.

[0015] Freeze-dried feed: processed through freeze-drying technology, retaining most of the nutrients and natural flavor of the raw materials.

[0016] Functions of prior art fish feed

[0017] Promote Growth: Provides comprehensive nutrition to support the healthy growth of fish.
