Embodiment 1
[0012] First, prepare the extract of river clam juice: after cleaning the fresh river clams, add two liters of water per kilogram of fresh river clams and boil for 5 minutes, pick out the shells, continue to boil for 2 hours, collect the boiled juice, and freeze-dry to obtain river clams. Clam Juice Extract. Then, in the basal feed of cultured fish, add the extract of clam boiled juice. Mix evenly, make granules, seal and store after drying.

Embodiment 3
[0016] First, prepare the extract of river clam juice: after cleaning the fresh river clams, add two liters of water per kilogram of fresh river clams and boil for 5 minutes, pick out the shells, continue to boil for 2 hours, collect the boiled juice, and freeze-dry to obtain river clams. Clam Juice Extract. Then, in the basal feed of cultured fish, add the extract of clam boiled juice. Mix evenly, make granules, seal and store after drying.
[0017] In order to verify the application effect of the lipid-lowering compound feed of fish clam juice prepared by the present invention, the following specific data will illustrate that the lipid-lowering compound feed of fish clam juice of the present invention can reduce the liver body index of carp and crucian carp in hibiscus. , visceral body index and the role of blood lipids:
[0018] Prepare the basic feed with the formula in Table 1, divide the sample hibiscuscarp and crucian carp into two groups, each group has two parallel...

Abstract
The invention discloses a preparation method of a corbicula fluminea juice lipid-lowering compound feed for fishes, wherein the preparation method specifically comprises the steps: firstly, adding a corbicula fluminea boiled juice extract into a fish culture basic feed, wherein the addition amount of the corbicula fluminea boiled juice extract is 0.25%-1.35% of the total weight of the basic feed; and then mixing the basic feed and the corbicula fluminea boiled juice extract evenly, preparing into particles, and drying to obtain the product. The prepared feed not only can significantly reduce the fatness and the liver index of fish bodies, but also can significantly reduce the content of serum triglyceride and total cholesterols.
Description
technical field [0001] The invention relates to a method for preparing a feed for cultured fish, in particular to a method for preparing a compound feed for reducing fat with clam juice used for culturing fish. Background technique [0002] At present, with the continuous development of intensive aquaculture in my country, fatty liver in fish with liver lipid excessive accumulation as the main pathogenic factor has attracted widespread attention. The disease has a high morbidity and high mortality rate in farmed fish, and has become an important problem hindering the further development of aquaculture. How to prevent and treat fatty liver in fish has become one of the problems that aquaculture needs to solve urgently. At present, it is an important means to prevent fish fatty liver by adding lipid-lowering factors in the feed in an appropriate amount to improve the fat metabolism of fish. [0003] As a traditional Chinese medicinal material, river clams are rich in essentia...
