Embodiment 1
[0049] 1. Preparation of enzymatic hydrolysis liquid and fish oil mixture
[0050] (1) proportioning by weight and volume:
[0051]
[0052] (2) Preparation:
[0053] Add seawater to the gonads of shrimp meat and mussels, grind them into shrimp meat and mussels gonads by a grinder, add 0.036kg of compound protease for enzymolysis to obtain an enzymatic hydrolysis solution, and pass the enzymatic hydrolysis solution through 200 mesh nylon cloth After filtration, the enzymatic hydrolysis liquid was added; 0.07 kg of fish oil was added to the enzymatic hydrolysis liquid, mixed to make a mixture of the enzymatic hydrolysis liquid and fish oil, and refrigerated at 6°C for later use.
[0054] Described seawater refers to seawater cooled to normal temperature after boiling seawater for 5 minutes.
[0055] The composite protease is composed of acid protease and papain in a weight ratio of 1:1.
[0056] The enzymolysis conditions are as follows: pH is 4.0, enzymolysis temperature...

Abstract
The invention belongs to the technical field of coral artificial cultivation. In particular, it relates to a preparation method of a composite liquid bait for artificial breeding of corals. Specifically: using shrimp meat, mussel gonads, and fish oil as raw materials, adding compound protease for enzymatic hydrolysis to prepare a mixture of enzymatic hydrolysis liquid and fish oil for use; using Ulva liquid and Microchloropsis as raw materials to prepare pseudo-microgreen spheres Algae and Ulva mixed solution for standby; Saccharomyces cerevisiae seed solution, Candida utilis seed solution and Rhodospirillum crimsonii seed solution are made into mixed bacteria seed solution for standby use; The above-mentioned standby solution is added with multivitamins to obtain coral artificial breeding complex liquid bait. The artificial coral culture composite liquid bait prepared by the invention has comprehensive nutritional components and good balance; the bait is harmless and has the effect of purifying water quality, and can improve the survival rate and growth rate of artificial coral culture.
Description
technical field [0001] The invention belongs to the technical field of coral artificial cultivation. In particular, the invention relates to a preparation method of compound liquid bait for artificial cultivation of corals. Background technique [0002] In recent years, although the proportion of live coral farming in the commercial aquarium market has been increasing, domestic live corals are almost entirely from wild capture; the market demand is out of touch with the current status of artificial coral breeding research, and domestic corals that meet market demand Breeding studies are almost non-existent. There are blanks in the screening of excellent ornamental traits of corals, breeding of improved varieties, and industrialization. Corals in the aquarium are in a good environment (eg, suitable water quality indicators, water flow, water temperature, lighting system, calcium content, etc.), and the corals in the aquarium will naturally increase. The main form of asexua...
