Embodiment 1

[0054] An artificial compound feed for promoting gonad development of broodstock Chinese sturgeon, which is made of the following raw materials in parts by weight:

[0055]

[0056] The inorganic salt premix and the vitamin premix in the feed formula are self-prepared premix, and their specific components and contents are as follows:

[0057] The vitamin premix is ​​prepared from the following raw materials in parts by weight: vitamin B 1 1 serving; Vitamin B 2 3 servings; Vitamin B 6 3 servings; Vitamin B 12 3 servings; Vitamin K 3 2 parts; inositol 79 parts; calcium pantothenate 6 parts; niacinamide 9 parts; folic acid 1 part; biotin 2 parts; vitamin A 22 parts; vitamin D 3 12 parts; 457 parts of vitamin C; 100 parts of vitamin E; 600 parts of choline chloride; 100 parts of astaxanthin; 200 parts of ethoxyquinoline; Vitamin premix.

[0058] Described trace element premix is ​​prepared by the raw material of following weight portion: copper sulfate (CuSO ) 3 pa...

Embodiment 2

[0069] The effects of three artificial compound feeds with different fat levels (10%, 14% and 18%) on the gonad development of Chinese sturgeon were studied. The formulas of the three feeds are shown in Table 1.

[0070] An artificial compound feed for promoting gonad development of broodstock Chinese sturgeon, which is made of the following raw materials in parts by weight:

[0071] The feed formula (unit: parts by weight) of different fat levels of table 1

[0072]

[0075] The vitamin premix is ​​prepared from the following raw materials in parts by weight: vitamin B 1 1 serving; Vitamin B 2 3 servings; Vitamin B 6 3 servings; Vitamin B 12 3 servings; Vitamin K 3 2 parts; inositol 79 parts; calcium pantothenate 6 parts; niacinamide 9 parts; folic acid 1 part; biotin 2 pa...

Embodiment 3

[0096] An application of artificial compound feed in the gonad development of broodstock Chinese sturgeon, the steps are:

[0097] A. Preserve the prepared Chinese sturgeon broodstock feed in a low temperature, dark and dry environment.

[0098] B. Before feeding every day, estimate the daily feeding rate according to the weather conditions. Then calculate the amount of feed that needs to be fed every day, and divide it into two feedings on average.

[0099] C. Stop adding oxygen to the water body when feeding, and reduce the water flow speed to ensure that the feed will not move after sinking to the bottom of the water body, so as to facilitate the feeding of Chinese sturgeon and reduce its time and energy consumption for foraging.

[0100] D. After half an hour of feeding, check the state of the remaining bait at the bottom of the water body, and recycle it in time, so as to accurately correct the feeding rate, reduce feed waste and pollution to the aquaculture water body. ...

Abstract

The invention discloses an artificially-compounded feed for developing a sexual gland of a parent Chinese sturgeon and a preparation method and application. The feed is made from fish meal, soybean meal, flour, chicken powder, fish oil, calcium hydrogen phosphate, a vitamin premix and a trace element premix according to a ratio. The preparation method comprises steps: A, mixing fish meal, soybean meal, chicken powder and flour; B, performing superfine pulverization to the mixed raw materials; C, putting the pulverized materials in a mixer, adding calcium hydrogen phosphate, the vitamin premix and the trace element premix to the mixer, performing mixing, adding seawater and fish oil into the mixer, and performing mixing; D, modulating the mixed materials by adopting a three-layer modulator; E, adopting an extruding-expansion process to prepare a granular feed; F, after the feed is dried, spraying the feed with oil fish through a vacuum sprayer, and after oil is absorbed by the granular feed, cooling the obtained product to the room temperature; and G, performing metering and packing. The feed is reasonable in formula and overall in nutrition, is convenient to apply in culture of Chinese sturgeons, and provides the Chinese sturgeons with balanced stable nutrition.

Description

technical field [0001] The invention belongs to the technical field of special aquaculture, and more specifically relates to an artificial compound feed for promoting the gonad development of Chinese sturgeon parent fish, and also relates to a preparation method of artificial compound feed for promoting the development of Chinese sturgeon parent Use of artificial compound feeds for gonad development in sturgeon broodstock. Background technique [0002] The Chinese sturgeon lives in large rivers and offshore seas. It is a benthic fish with migratory or semi-migratory characteristics. From May to June in spring and summer, the hibiscus cluster in the mouth of the river, and go up to the upper reaches of the river in autumn. The food of the Chinese sturgeon is mainly some small or slow-moving benthic animals, including shrimps and crabs, fish, molluscs and aquatic insects. [0003] Chinese sturgeon has typical anadromous spawning characteristics. Chinese sturgeon usually liv...
