Shellfish compound feed based on enteromorpha and preparation method thereof

Abstract

The invention discloses a shellfish compound feed based on enteromorpha and a preparation method thereof. The shellfish compound feed comprises 100-120 parts by weight of enteromorpha dry powder, 120-180 parts by weight of distilled water, 3-5 parts by weight of probiotics, 15-20 parts by weight of fish meal, 5-10 parts by weight of fish oil, 1.5-2 parts by weight of sodium alginate and 1-1.5 parts by weight of calcium chloride. The preparation method comprises the following steps: cleaning enteromorpha to remove impurities, and then drying the cleaned enteromorpha; grinding the dried enteromorpha to obtain enteromorpha dry powder; weighing the raw materials, and uniformly mixing and stirring to obtain a mixed material; and storing the mixed material in a sealed oxygen-free environment for 48-72 hours, and keeping the temperature at 32-37 DEG C to prepare the shellfish compound feed. Compared with the prior art, the method has the advantages that the enteromorpha is used as a main component of the shellfish compound feed, the added value of the enteromorpha is increased, resource utilization of the enteromorpha is realized, and the environment is protected. The method is simple to operate, no excessive complex equipment is aquired, feasibility is high and rapid large-scale production can be realized.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a shellfish compound feed based on enteromorpha and a preparation method thereof. Background technique [0002] Enteromorpha, commonly known as moss strips, green seaweed, etc., belongs to the genus Enteromorpha of the Chlorophyta Chlorophyceae, Ulva orders, and Ulvaceae. It is a kind of green algae that can multiply due to eutrophication of water bodies, which can form green tides and pose serious harm to the marine ecological environment. Since 2007, green tides of Enteromorpha have appeared in the sea area of ​​Jiangsu Province and the outer sea, which has brought serious adverse effects on the economy of Jiangsu and other provinces, and directly affected the balance of nearshore ecosystems. Enteromorpha in the Yellow Sea was generally first observed in the Jiangsu waters, showing the periodic characteristics of "emergence-rapid growth-explosion-continuation-decline-extin...

Problems solved by technology

On the other hand, the nutrients contained in it are indeed rich. If Enteromorpha is directly cleaned up but not used in order to protect the marine environment and ecology, it will inevitably cause waste of resources.
