Feed capable of increasing Mandarin fish spawning amount and preparation method thereof

Abstract

The invention discloses a feed capable of increasing Mandarin fish spawning amount and a preparation method thereof. The feed capable of increasing Mandarin fish spawning amount is prepared from the following raw materials in parts by weight: Chinese sorghum flour, loach meal, blood meal, papayas, shrimp shell powder, water flea powder, lettuce leaves, soybeans, spirulina, skimmed milk powder, Zornia gibbosa, palm oil, herbs of curculigo, forestry greenstar roots and lotus flower powder. Compared with prior art, the feed capable of increasing Mandarin fish spawning amount disclosed by the invention has the following advantages: multiple raw materials are prepared into a granular feed after different treatments, so that the feed has the effects of promoting oogonia mitochysis of female Mandarin fishes, increasing ovulation rates of parent fishes, raising fertilized egg amounts, promoting precipitations of oocyte nutrients and improving ovum qualities so as to raise fertilization rates and hatching rates; and economic benefits of culturing are thereby effectively increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a feed for increasing the egg production of mandarin fish and a preparation method thereof. Background technique [0002] Mandarin fish is also known as mandarin fish, squid, ridge flower fish, fat mandarin fish, etc. Its meat is tender and delicious.

[0002] Mandarin fish is also known as mandarin fish, squid, ridge flower fish, fat mandarin fish, etc. Its meat is tender and delicious. It is also known as China's "four freshwater fish" together with Yellow River carp, Songjiang four-gilled perch, and Xingkai Lake big white fish. "Famous fish", distributed in freshwater rivers and lakes all over the country, is the top grade of fish. It contains protein, fat, a small amount of vitamins, calcium, potassium, magnesium, selenium and other nutrients, which can tonify deficiency and be easily digested, which is helpful for tuberculosis patients. It is rich in antioxidant ingredients and is welcomed by consumers. Therefore, the scale of mandarin fish farming is gradually expanding. The amount of mandarin fish spawning directly affects the breeding benefits. Survival rate is used to increase production, which severely restricts the production of mandarin fish
