[0003] At present, there are very few studies on the nutritional requirements and feed of the golden-threaded barb in Dianchi Lake, and there is no special compound feed. Its artificial breeding is often replaced by other fish feeds, which will inevitably lead to unbalanced nutrition, slow growth, low feed efficiency, and poor breeding water quality. Serious pollution and disease breeding and other problems

[0039] Weigh 26kg of domestic fish meal, 6kg of corn gluten meal, 16kg of soybean meal, 6kg of cottonseed meal, 12kg of rapeseed meal, 6.43kg of wheat bran, 14kg of high-gluten flour, 7kg of brewer’s yeast, 0.2kg of fish oil, 3.5kg of soybean oil, and 0.5kg of soybean lecithin , calcium dihydrogen phosphate 1kg, vitamin C phosphate 0.05kg, choline chloride 0.3kg, salt 0.2kg, ethoxyquinoline 0.02kg, mineral premix 0.5kg, vitamin premix 0.3kg.
[0040] The raw materials of the above-mentioned examples 1-3, except fish oil and soybean oil, were pre-crushed through a 60-mesh sieve, and then all the raw materials were mixed evenly by a twin-shaft paddle mixer; (adjust the feed particle size according to the size of the fish body), dry and cool to obtain the Dianchi golden linema compound feed of the present invention.
[0041] In September 2012, a 10-week breeding experiment of golden-haired barb (5.1 g on average) in Dianchi Lake was carried out in the aquaculture laboratory. Usi...

Abstract
The invention relates to a Dianchi Sinocyclocheilus graham mixed feed and belongs to the technical field of aquaculture. The Dianchi Sinocyclocheilus graham mixed feed comprises the following components: by weight, 18-26% of domestic fish meal, 6-8% of corn gluten meal,16-20% of soybean meal, 6-10% of cottonseed meal, 12-14% of rapeseed meal, 4.33-6.43% of wheat bran, 10-14% of bread flour, 7-8% of brewers yeast, 0.2-1.4% of fish oil, 3.4-3.5% of soya-bean oil, 0.5-1.0% of soya lecithin, 0.7-1.5% of calcium dihydrogen phosphate, 0.05-0.1% of Vitamin C phosphate, 0.2-0.3% of choline chloride, 0.2-0.4% of salt, 0.01-0.03% of ethoxy quinoline, 0.5-1.0% of a mineral premix, and 0.3-0.8% of a vitamin premix. According to the invention, life habit, nutritional requirement and digestion characteristic of Dianchi Sinocyclocheilus graham are fully considered, and raw materials which are easily digested by Dianchi Sinocyclocheilus graham are used for reasonable compatibility; the feed has good palatability; utilization rate of the feed is high, and the feed causes little pollution to a water body; and raw material sources are stable, price is low, and the feed is suitable for large-scale breeding of Dianchi Sinocyclocheilus graham.
Description
technical field [0001] The invention relates to a compound feed, in particular to a compound feed for golden-threaded carp in Dianchi Lake, and belongs to the technical field of aquaculture. Background technique [0002] The golden-threaded barb (Sinocyclocheilus grahami) in Dianchi Lake belongs to Cyprinidae, Cyprinidae, Subfamily, and the genus Golden-threaded barb. It is also known as golden thread fish, pineapple fish, and small cave fish. The meat of golden-threaded barb in Dianchi Lake is fresh and tender. It has been regarded as a treasure in the past dynasties, and has high edible value and development potential. Under artificial conditions, the golden-threaded barb in Dianchi Lake has the characteristics of easy domestication, high survival rate, fast growth, strong disease resistance, and easy catch. It is suitable for large-scale promotion and breeding. [0003] At present, there are very few studies on the nutritional requirements and feed of the golden-threaded...
