What should fish eat to stay alive (detailed introduction)

Fish are a broad group of organisms, and different species of fish have different food needs. The following is a detailed introduction to the food requirements of fish, including their eating habits in the natural environment and under cultured conditions.

In the natural environment:

In their natural environment, different species of fish will eat different types of food, including:

Plankton: Many fish eat plankton, such as phytoplankton and zooplankton, such as planktonic crustaceans and the larvae of small aquatic insects.

Benthic organisms: Some fish mainly feed on benthic organisms, such as shrimps, clams, and worms.

Other fish: Some large predatory fish will feed on other fish.

Under breeding conditions:

In aquaculture and aquaculture, fish are specifically fed appropriate feeds to meet their nutritional needs. Generally fish diets can be divided into the following categories:

Artificially prepared feed: For different stages and types of fish, artificially prepared feed is usually provided in the form of pellet feed, fish feed pellets, fish feed powder, etc. These feeds usually include the required nutrients such as proteins, fats, carbohydrates, vitamins and minerals.

Live bait: In some special cases, fish farmers may also choose to use live bait, such as water fleas, shrimps and other aquatic organisms, for raising specific fish.

Special dietary needs:

Some specific species of fish have special dietary needs. For example, some herbivorous fish prefer plant-based feeds, while carnivorous fish require more protein.

The size and species of fish, the environment in which they are kept, and their stage of growth should all be taken into consideration when providing feed. In addition, breeders need to pay attention to feed consumption and ensure that the type and amount of feed can meet the growth needs of the fish.

In general, fish have diverse food needs, and providing the right variety and quantity of diet for different species of fish is important for their growth and health.
