Embodiment 1

[0036] Embodiment 1: formulate feed by No. 001 formula shown in table 1, raise 10.2g mullet juveniles for 60 days, feed coefficient is 1.24, specific growth rate (SGR, % / day) 2.27, survival rate is 95%, and throw something and feed Compared with the eel diet, there was no significant difference in growth and feed coefficient, while the survival rate was increased by 25%.

Embodiment 2

[0037] Embodiment 2: formulate feed by No. 002 formula shown in table 1, raise the mullet juvenile fish of 1.77g for 60 days, feed factor 1.39, specific growth rate (SGR, % / day) 3.22, survival rate 98%, ammonia nitrogen emission is 18mgKg -1 h -1 , the phosphorus utilization rate is 61%, compared with the combination of feeding eel feed and fresh bait, the feed coefficient is reduced by 40%, the survival rate is increased by 28%, the phosphorus utilization rate is increased by 20%, and the ammonia nitrogen discharge and phosphorus discharge are reduced. 30%.

Embodiment 3

[0038] Embodiment 3: formulate feed by No. 003 formula shown in table 1, raise the mullet juvenile fish of 52.8g for 60 days, feed factor 1.52, specific growth rate 1.92, survival rate 97%, ammonia nitrogen discharge 12mgKg -1 h -1 , compared with the combination of eel feed and fresh bait, the specific growth rate increased by 20%, the feed coefficient decreased by 25%, and the survival rate increased by 20%. Ammonia nitrogen emissions are reduced by 20%.

Abstract

The invention relates to compound feed suitable for juvenile fish of myxocyprinus asiaticus, which is characterized by comprising the following components in percentage by weight: 40 to 45 percent of crude protein, 10 to 14 percent of crude fat, 20 to 25 percent of total sugar, 0.70 to 0.85 percent of available phosphorus, 6 to 10 percent of moisture, 2.0 to 2.5 percent of composite vitamin, 1.5 to 2.0 percent of composite mineral salt, 0.3 to 0.5 percent of immune potentiator, 0.3 to 0.5 percent of antioxidant and 2 percent of adhesive. The feed comprises the following raw materials in percentage by weight: 60 to 75 percent of protein source raw material, 8 to 10 percent of fat source raw material, 10.0 to 15.0 percent of sugar source raw material, 2.0 to 2.5 percent of composite vitamin, 1.5 to 2 percent of composite mineral salt, 0.3 to 0.5 percent of immune potentiator and 0.3 to 0.5 percent of antioxidant. The compound feed of the invention solves the problem of unbalanced nutrition of the current compound feed for feeding the juvenile fish of the myxocyprinus asiaticus, and reduces the environment pollution during feeding.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a compound feed suitable for juvenile mullet and its application. Background technique [0002] The mullet is an important economic fish and one of the important ornamental fish. It is listed as a national second-class aquatic wildlife protection animal. The fish has a broad market prospect because of its large size, peculiar body shape, bright body color, fast growth, delicious meat, and high economic benefits. At present, with the artificial breeding and nursery technology of mullet becoming more and more mature, juvenile mullet can eat compound feed well after being domesticated under the breeding conditions such as ponds and cages. Since there is no special compound feed for mullet fish on the market, farmers now mostly use eel feed and fresh bait for feeding. Seriously, the survival rate is low, coupled with its high cost and possible uneven or excessive nu...
