Problems solved by technology

At the same time, long-term high-dissolved oxygen water will also increase the metabolic burden of the fish. Excessive dietary protein and fat cannot be converted into the energy required for growth in time, resulting in a large amount of fat accumulation in the abdomen, liver and intestines of the fish.

preparation example Construction

[0018] In the present invention, the preparation method of the compound Chinese herbal medicine preferably comprises: freeze-drying each component (lycium barbarum leaves, Acanthopanax stalks, lotus leaves, capillary wormwood and astragalus stems and leaves), grinding and pulverizing, and passing through a 80-mesh sieve . In the present invention, there is no special limitation on the operation methods of freeze-drying and grinding, and conventional operations well known to those skilled in the art can be used.

[0019] The present invention also provides a feed for promoting fat utilization in tilapia flowing tank recirculating aquaculture based on the compound Chinese herbal medicine described in the above technical scheme, and the feed includes a basal ration and a compound Chinese herbal medicine. In the present invention, the basal diet preferably includes 26-30% protein by mass and 5-10% fat by mass.

[0020] The basal diet of the present invention includes 26-30% prote...

Embodiment 1

[0028] A set of feed composition and feeding method for promoting fat utilization in tilapia running tank recirculating aquaculture includes the following steps:

[0029] Step 1. In Yangzhong, Jiangsu, select six 800-square-meter water tanks, and stock 20,000 tilapias in each water tank, and the size of the fish is about 250g. Three flow tanks were used as control groups. Before the experiment, a conventional commercial fish feed was prepared, in which the protein level was 29%, and the fat level was 4%. Three flow tanks were used as the experimental group. Before the experiment, the basal diet with protein level of 27% and fat level of 7% was prepared, and compound Chinese herbal medicine was added. In the two groups of feeds, the feed composition was the same, and the protein and fat levels of the feed were adjusted by fish meal and soybean oil. The specific feed formula is shown in Table 1.

Embodiment 2

[0045] A set of feed composition and feeding method for promoting fat utilization in tilapia running tank recirculating aquaculture includes the following steps:

[0046] Step 1. In Changzhou, Jiangsu Province, select six 800-square-meter water tanks, and stock 15,000 tilapias in each water tank, and the size of the fish is about 50g. The basal diet with a protein level of 30% and a fat level of 7% was prepared; 3 flow tanks were used as the control group, and only the basal diet was fed; 3 flow tanks were used as the experimental group, and the basic diet supplemented with compound Chinese herbal medicine was fed. Grain feed.

[0047] The 2nd step, compound Chinese herbal medicine preparation: by weight, every 100g compound Chinese herbal medicine contains 20g of Lycium barbarum leaves, 45g of Acanthopanax stems, 20g of lotus leaves, 10g of capillary wormwood, and 5g of astragalus stems and leaves; in the 2nd step, the compound recipe The Chinese herbal medicine is prepared ...

Abstract

The invention relates to a compound Chinese herbal medicine, a feed and a feed feeding method for promoting fat utilization in tilapia running water tank circulating aquaculture, and belongs to the technical field of breeding management and feed feeding. The compound Chinese herbal medicine of the present invention comprises the following components in mass percentage: 15-25% of wolfberry leaves, 40-50% of Acanthopanax stems, 15-25% of lotus leaves, 5-15% of capillary and 3-7% of Astragalus stems and leaves. The feed made from the compound Chinese herbal medicine of the present invention can enhance the absorption and utilization of feed fat in tilapia flowing tank recirculating aquaculture, reduce fat deposition, effectively improve the absorption and utilization of feed fat, and reduce liver fat deposition , reduce the incidence of fatty liver and related diseases.

Description

technical field [0001] The invention relates to aquaculture, in particular to the technical field of aquaculture management and feed feeding, in particular to a compound Chinese herbal medicine, feed and a feed feeding method for promoting fat utilization in tilapia running water tank circulating aquaculture. Background technique [0002] Flow tank circulating aquaculture integrates high-density cultivation, online monitoring of water quality, and factory management. It can not only realize high-density intensive cultivation of breeding objects, but also perform biological purification treatment on residual aquaculture wastewater to achieve self-purification and self-repair of aquaculture water. , so as to realize the effective, stable and sustainable development of the aquaculture industry. At present, it has been widely promoted and applied in Jiangsu, Fujian, Zhejiang and other provinces and cities. The main breeding objects are yellow catfish, crucian carp, bream, perch,...
