Problems solved by technology

At present, most domestic research institutions cannot realize the indoor rearing and breeding of Macrobrachium japonicus, and the shrimps used for research are all collected in the wild, which is very easy to be brought into the laboratory from the wild to contaminate the laboratory with bacteria, and the species of shrimp used is not guaranteed. Therefore, to provide an operable Japan's indoor breeding method plays an important role in obtaining high-quality biological test materials, ensuring the smooth development of drug safety evaluation, and effectively evaluating the environmental toxicity of drugs.

[0028] How to raise Macrobrachium japonica

[0029] 1. Material preparation:

[0030] Breeding tank: choose a square glass tank with a volume of about 500 L (length×width×height: 1.2 m×0.6 m×0.7 m), soak the glass tank with 20 mg / L potassium permanganate solution for 30 minutes, and rinse with clean water Clean as a breeding tank. The breeding tank is placed in a place without direct sunlight, and a circulating water system is installed in the breeding tank.

[0031] Breeding water: tap water stored for more than 24 hours and treated with aeration, pH 7.5, water hardness (as CaCO 3 total) was 46 mg / L, and the ammonia nitrogen content was 0.01 mg / L.

[0032] 2. Construct a simulated ecosystem: add water to the breeding tank until the water surface height is 0.5 m. Aquatic plants, Scenedesmus obliques, daphnia large, snails, gravel, tiles, 40-mesh nylon grid with a size of 0.6 m×0.5 m, etc. were placed in the breeding tank. The coverage rate of aquatic plants is about 6% of...

Embodiment 2

[0036] The breeding method of Macrobrachium japonicus, the feeding water used in this embodiment is tap water stored for more than 24 h and treated with aeration, the pH is 7.5, and the water hardness (measured as CaCO 3 total) was 46 mg / L, and the ammonia nitrogen content was 0.01 mg / L.

[0037] 1. Select a square glass jar with a volume of 8 L (length×width×height: 0.2 m×0.2 m×0.2 m), soak the glass jar with 20 mg / L potassium permanganate solution for 30 minutes, and rinse it with clean water as a breeding tank.

[0038] 2. Put one ovum-embracing shrimp into the above-mentioned breeding tank, add feeding water until the water surface height is 0.1m, and use an air aeration pump to fully aerate, control the water temperature at 26-28°C, and feed one earthworm and a small amount of water every day. Tofu. After 21 days, the daphnia larvae were separated from the broodstock, and the broodstock shrimp were put back into the simulated ecosystem to continue feeding, and the daphn...

Abstract

The invention discloses a macrobrachium nipponensis indoor feeding and breeding method. The method includes the following steps: constructing a simulation ecological system, placing macrobrachium nipponensis into the simulation ecological system, feeding the macrobrachium nipponensis one time each day, and changing water one time every one week; selecting berried shrimps from the macrobrachium nipponensis to serve as parent shrimps which are placed into cultivation jars to be fed, and placing one berried shrimp into each jar; after larvae break away from the parent shrimps, placing the parent shrimps back into the simulation ecological system to be fed continuously, and placing the larvae into juvenile prawn cultivation jars for cultivation; after the zoaea larvae are just hatched, feeding the zoaea larvae two times each day, and feeding the zoaea larvae one time after the zoaea larvae get into the larva stage. According to the macrobrachium nipponensis indoor feeding and breeding method, the operability is high, frequent water changing and manual management are not needed, it can be guaranteed that the macrobrachium nipponensis can live and conduct breeding in a room for a long time, and a guarantee is provided for the smooth development of medicine environment safety assessment.

Description

technical field [0001] The invention relates to the technical field of animal feeding, in particular to a method for indoor rearing and breeding of Macrobrachium japonicus. Background technique [0002] Macrobrachium japonicus, also known as freshwater shrimp, belongs to the subclass Molecula, Decapod, Paradea, Spratidae, Macrobrachium, mainly distributed in Japan and China, and is one of the main economic shrimps in freshwater in my country. Except for the western plateau area, it is widely distributed in lakes, rivers, reservoirs, ponds and ditches all over the country. It has the characteristics of miscellaneous food habits, fast growth, high fecundity and strong disease resistance. The protein content of Macrobrachium japonicus is extremely high, and the shrimp shell is an important chemical raw material, which is widely used in many aspects such as textiles, food, environmental protection, and medicine. Therefore, Macrobrachium japonicus has high economic value. At th...
