Problems solved by technology

However, due to the low reproduction rate and slow growth rate of yellow catfish in natural waters, the wild yellow catfish caught in natural waters can no longer meet the market demand. Therefore, yellow catfish is artificially raised as an economic fish in various places
At present, the artificial cultivation of yellow catfish in Guangdong Province, Zhejiang Province and other regions has a certain scale, but there are still some technical problems in the artificial cultivation of yellow catfish, and the breeding technology is not yet mature.
Now feeding the yellow catfish with fish feed on the market, the survival rate and weight gain rate of the fish are low, and it is easy to cause the yellow catfish body to become lighter (white), and the yellow catfish in natural water bodies, due to eating A large number of algae and plankton rich in carotenoids, the body color is relatively bright, under normal circumstances, there are black spots on the side of the body, and the rest of the body is yellow

Embodiment 1

[0021] Carry out throwing something to feed the yellow catfish test in the pond, the average size of the yellow catfish is 56.7 grams / tail, the pond area is 1 mu, stocking density 4000 tails / mu, lasted 103 days, the weight percent of each component of feeding compound feed is : Fish meal 45%, meat and bone meal 4%, flour 15%, corn 5%, soybean meal 10%, rapeseed meal 5%, fish oil 2%, corn gluten meal 10%, multivitamin 1.0%, multimineral 1.0%, immune enhancer 0.1%, liver protection agent 0.2%, choline 0.2%, calcium dihydrogen phosphate 1.5%.

Embodiment 2

[0023] Carry out throwing something to feed yellow catfish test in the pond, the average size of yellow catfish is 65.3 grams / tail, pond area is 1 mu, stocking density 4000 tails / mu, lasts 103 days, the weight percent of each component of feeding compound feed is : Fish meal 35%, meat and bone meal 4%, flour 15%, corn 8%, soybean meal 15%, rapeseed meal 7%, fish oil 2%, corn gluten meal 10%, multivitamin 1.0%, multimineral 1.0%, immune enhancer 0.1%, liver protection agent 0.2%, choline 0.2%, calcium dihydrogen phosphate 1.5%.

Embodiment 3

[0025] Carry out throwing something to feed yellow catfish test in the pond, the average specification of yellow catfish is 69.9 grams / tail, pond area is 1 mu, stocking density 4000 tails / mu, lasts 106 days, the weight percent of each component of feeding compound feed is : Fish meal 25%, meat and bone meal 4%, flour 15%, corn 8%, soybean meal 20%, rapeseed meal 7%, fish oil 2%, corn gluten meal 15%, multivitamin 1.0%, multimineral 1.0%, immune enhancer 0.1%, liver protection agent 0.2%, choline 0.2%, calcium dihydrogen phosphate 1.5%.

[0026] Embodiment effect is as follows:

[0027] Example 1

[0028] The body weight gain rate, feed coefficient and survival rate of the yellow catfish were 136%, 1.37 and 98.9% respectively. The body color of the yellow catfish in the test was normal, and the body weight of the yellow catfish fed by this compound feed was higher than that of the common fish feed. The rate is high, the amount of feed is small, the survival rate of the fish i...

Abstract

The invention provides a compound feed of pelteobagrus fulvidraco food fish and a preparation method thereof. The compound feed comprises the following components in percentage by weight: 20-45% of fish meal, 4-10% of meat and bone meal, 15-25% of flour, 4-10% of corn, 10-25% of soy bean meal, 4-10% of rapeseed meal, 1-4% of fish oil, 10-25% of corn gluten meal, 1.0% of multivitamins, 1.0% of multiminerals, 0.1% of immunopotentiator, 0.2% of liver protecting agent, 0.2-0.4% of choline and 1-2% of calcium biphosphate. The compound feed has high quality grinding particle size, mixing uniformity, feed shaping property, water resistance and other characteristics. The pelteobagrus fulvidraco food fish fed with the compound feed has body color close to the natural body color, and the compound feed can improve the anti-virus capability of the pelteobagrus fulvidraco, shorten the breeding cycle, reduce the breeding cost, reduce the sources of the diseases and water body pollution and has obvious economic and environmental benefits.

Description

technical field [0001] The invention relates to a compound feed for edible fish of yellow catfish and a preparation method thereof. Background technique [0002] Yellow catfish scientific name Pelteobagrus fulvidraco (Richardson), commonly known as Huanglading, Huangyatou, etc., are distributed in all waters of the country except the western plateau. The yellow catfish body is blue-yellow, mostly with irregular brown markings, the fins are gray-black with yellow, the meat is tender, its muscles are rich in nutrients, without intermuscular spines, the meat is delicious, and the edible ratio is high. Food fish with high economic value. For a long time, the yellow catfish has been treated as a small wild fish because of its small size. With the improvement of people's living standards, the consumption of aquatic products has rapidly changed to "quality-oriented", thus re-understanding the economic value of many aspects such as the nutritional value of the yellow catfish. "...
