Description

ornamental fish feed

technical field

The present invention relates to fish feed, especially ornamental fish feed.

Background technique

Ornamental fish are loved by people for their unique shape, graceful movement, and colorful colors. While loving them, they must pay attention to their health and growth. It is very important to choose what kind of feed for them. At present, the feed for ornamental fish is mainly divided into There are three types of animal feed, plant feed, and artificial compound feed. Artificial compound feed can effectively eliminate many deficiencies in animal and plant feed. However, there is no compound artificial feed on the market at present, and it is difficult to meet the feed needs of different ornamental fish.

Fly maggot powder is produced by artificially rearing sterile housefly after laying eggs, hatching into larvae through suitable temperature, humidity and bait, and then after separation-washing-drying-milling, the crude protein of fly maggot powder is The content is generally 60-65%, of which the content of 18 kinds of amino acids N+E can reach more than 57%, the content of essential amino acids E is about 25%, the ratio of essential amino acid content E to non-essential amino acid content N is greater than 0.6, fly maggot powder amino acid It is high in content and rich in nutrients, including fly maggot protein and epidermis, among which the content of chitin in the epidermis can reach 60%, which has strong antibacterial ability and is especially suitable for use as feed.

Contents of the invention

The purpose of the present invention is to provide a feed for ornamental fish that can improve the survival rate and growth rate of ornamental fish and enhance its disease resistance and immunity.

Technical scheme of the present invention is as follows:

A kind of ornamental fish feed, its component and weight percent scope are:

Peruvian Fish Meal 20-35% Fly Maggot Meal 5-20%

Cornstarch 18-23% Flour 10-15%;

Soybean meal 5-10% Brewer's yeast powder 3-7%

Dehydrated Vegetables 2-6% Spirulina 2-3%

Vitamin C 0.5-1%;

Its preferred ratio is

Peruvian Fish Meal 25% Fly Maggot Meal 15%

Cornstarch 23% Flour 15%;

Soybean meal 10% Brewer's yeast powder 5%

Dehydrated Vegetables 4% Spirulina 2%

Vitamin C 1%.

The ornamental fish feed disclosed by the invention can effectively improve the survival rate and growth rate of juvenile fish, and enhance its disease resistance and immunity. The following is the comparative test situation of using ordinary artificial compound feed and the feed of the present invention.

1. Test conditions:

①. Size of household fish tank: length×width×height 1200×500×600mm;

②, water temperature: 22 ℃ ~ 28 ℃, water change cycle 7 days / time (1/3);

③. Feed dosage: 3 times a day, 6 days as a cycle, each cycle feed dosage increased by 5 grams/week, 5 grams/time in week I, 10 grams/time in week II, 15 grams/time in week III, In the future, keep 20 grams/time;

4., sample size: totally 4 groups, every group is divided into two subgroups (common artificial compound feed and feed of the present invention, each subgroup respectively throws 50 tails of hatchlings after 20 days;

⑤. Test period: 60 days.

2. Test results:

(1) Visually observe the feces excreted by ornamental fish

Common artificial compound feed group feces is a thread, and the feed group feces of the present invention is loose granular matter, illustrating that the digestibility of ornamental fish improves after adding the feed of the present invention;

(2) Observe the color of ornamental fish

Add the feed group fish of the present invention, and the color of the fish group is obviously brighter than that of the common artificial compound feed group, which shows that adding the feed of the present invention has a brightening effect on ornamental fish;

(3) Growth rate of ornamental fish

After adding the feed of the present invention, along with the increase of the amount of fly maggot powder among the present invention, the weight of ornamental fish of the group using common artificial compound feed increases on average by 210.75 grams, and every fish increases by an average of 4.22 grams/bar. When the amount of fly maggot powder reaches 20 %, the growth rate is the fastest, but it should be controlled within 20% due to cost constraints;

(4) Survival rate of ornamental fish

After adding the feed of the present invention, compared with the group using common artificial compound feed, the survival rate of juvenile fish increased by 16.5% on average, but when the amount of fly maggot powder added exceeded 20%, the survival rate increased not obviously.
