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 artificial breeding of coral, and particularly relates to a preparation method of composite liquid bait for artificial breeding of coral. Specifically, the composite liquid bait is prepared through the following steps of by using shrimp meat, mussel sexual gland and fish oil as raw materials, adding compound protein enzymes, and performing enzymolysis to prepare enzymolysis supernate and fish oil mixed liquor for standby application; by using ulva lactuca liquid and nannochloropsis oculata as raw materials, preparing nannnochloropsis gaditana and ulva lactuca mixed liquor for standby application; enabling saccharomyces cerevisiae, candida utilis seed liquid and rhodospirillum rubrum seed liquid to be made into mixed bacterium seed liquid for standby application; adding complex vitamins to all of the liquid for standby application so as to obtain the composite liquid bait for artificial breeding of coral. The composite liquid bait for artificial breeding of coral, prepared by the method disclosed by the invention, is comprehensive in nutrient components and good in balance, is harmless, and has the efficacy of purifying water quality, and the survival rate and the growth rate of the artificially bred coral can be increased.
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...
