Problems solved by technology

[0002] Aquatic products differ from livestock and poultry in that they have higher requirements for protein content in the feed. Fishmeal generally accounts for 25-50% or more of the formula in the seedling feeding feed of aquatic products in the prior art. However, fishmeal is in short supply day by day, and the price It is relatively high, and it is difficult to achieve the expected feeding effect; the record of the salt pan organism-Artemia has a history of more than 200 years, but the development and research of Artemia is a young biological science, until the fifth and sixth of the 20th century. In the 1900s, scientists in the United States and Norway discovered the value of Artemia successively, and opened up a way to use Artemia eggs and larvae to cultivate various aquatic animal seedlings. Influenced by factors such as parthenogenetic reproduction) and other factors, during the breeding process of aquatic products, due to the mixing of hatched eggshells and Artemia larvae, seedlings eating eggshells are likely to cause indigestion and affect health. Secondly, eggshells are deposited in the nursery pool polluted water quality
