What are the types of ornamental fish feed?

Like edible fish, ornamental fish need comprehensive and balanced nutrients, the difference is that ornamental fish focus on health and color, edible fish focus on growth rate and feed efficiency, bait can be divided into natural bait and synthetic bait, let's take a look!

Natural bait for ornamental fish

Natural bait includes live bait and its frozen or dried products, including water flea, blood worm, harvest shrimp, silk earthworm, creek shrimp, bread worm, silkworm pupa, etc., for ornamental fish, live bait is the best source of food and nutrition, but live bait also has many shortcomings.

1. It is not easy to keep for a long time.

2. It is easy to carry parasites and bacteria.

3. The source and supply of live bait can not be guaranteed.

4. Long-term use of a certain kind of raw bait alone is easy to cause nutritional imbalance in the fish, resulting in illness or death.

Artificial feed for ornamental fish

1. Thin slice feed: the artificial feed developed in Europe and the United States in the early stage is mainly thin slice, which has been used up to now. Thin slice feed is more suitable for small fish, and it is convenient to feed, but it is not easy to remove the residual bait at the bottom of the cylinder, which is easy to cause water pollution and fish pathological changes for a long time.

2. Expanded feed: according to the floating or sinking needs of all kinds of ornamental fish, the expanded pellet feed products suitable for their growth and performance should be maintained for at least 3 hours in water, so the expanded feed is the feed with the least water pollution. Its particle size can be made from 0.5mm of micro particles to large particles of 7mm, so from fry to adult fish, small fish to large fish have puffed feed suitable for their caliber, and the granulation of puffed feed can be fed regularly in an automatic feeder, which is the most ideal feed for raising ornamental fish at present.

Comparison between artificial feed and natural feed

The main results are as follows: 1. The source of artificial feed is relatively stable, and it can be supplied continuously all the year round, while natural bait is restricted by season, and it avoids the pain of using a lot of manpower to fish and insects, and reduces the cost.

2. Artificial feed can be adjusted at any time according to the different nutritional needs of ornamental fish at different stages of growth and development, which not only meets the nutritional needs of ornamental fish at different stages, but also reduces the cost.

3. According to the change of season, artificial diet can add a certain amount of drugs to prevent and cure some common fish diseases and improve the survival rate of young fish.

4. Artificial feed can artificially add some biological pigments to deepen the pigments of fish and enhance the ornamental value of fish.

5. Artificial feed can kill some bacteria and pathogens after a certain high temperature treatment.

6. After the artificial feed is scattered, it floats on the water for a short time, and then sinks slowly, so that it takes into account the fish in different feeding areas, which can be said to be a kind of omni-directional fish food.
