Description
Technical Field
The invention belongs to the technical field of fish feed, and particularly relates to fish feed containing copepods and a preparation device thereof.
Background
The breeding of the fish in the aquaculture industry is a crucial link, a nutrient source taken by the young fish which just hatch is called initial feed, and the quality of the initial feed has important influence on the improvement of the resistance and survival rate of the breeding. The initial bait for fish is usually living bait, such as copepods and rotifer artemia, and then is converted into artificial synthetic feed along with the growth of fish, because of palatability problems caused by habit of fish formation, fry is not too willing to eat the artificial synthetic fish feed, so that the survival rate of the fry is reduced, and the water quality is polluted by redundant artificial synthetic fish feed. The existing artificial synthetic fish feed has single nutrient component, the copepods contain rich unsaturated fatty acid, DHA and EPA, and can provide rich nutrient substances for seedling culture and survival rate, and the copepods are in natural water areas: in inshore, ponds and lakes, copepods groups can appear in large-scale outbreak, enough copepods individuals can be collected seasonally to serve as fish bait additives, the nutrient content of the bait is increased, and the fluctuation of the feeding rate in the conversion process of the fry bait is reduced.
Disclosure of Invention
The invention aims to overcome the defect of low ingestion rate of fry in the feed conversion process in the prior art, and provides a fish feed containing copepods, which is added with copepods to increase the ingestion rate, can swim after being put into water to increase the appetite of fish; in addition, a device for preparing the fish feed with the copepoda components is provided, and the device is simple in structure.
In order to achieve the purpose, the invention adopts the following technical scheme:
a fish feed containing copepods comprises an edible body and a gas generator, wherein copepods are arranged in the edible body. The edible body contains copepods to increase the ingestion rate and nutrition, and in addition, the gas generating body generates a large amount of gas after contacting water, and the edible body swims in the water under the promotion of the gas to increase the appetite of the fishes.
Preferably, one side of the edible body is provided with a caulking groove, and the gas generating body is positioned in the caulking groove. The structure is simple, in addition, the gas generating body sprays gas to the opening of the caulking groove, so that the edible body can swim fast.
Preferably, the edible body has a cylindrical structure, and the gas generator is located on one of the end faces of the edible body. The structure is simple.
Preferably, the gas generator raw material includes sodium bicarbonate and citric acid. Sodium bicarbonate reacts with citric acid to produce carbon dioxide.
Preferably, the copepod is 1/5-1/6 by weight of the edible body. Moderate proportion and balanced nutrition.
Preferably, the gas generant has a volume of 1/3-1/4 of the edible body. The gas generating body has moderate volume, generates more carbon dioxide, and simultaneously does not generate excessive carbon dioxide, so that the fish is easy to swell.
The utility model provides a preparation facilities of fish fodder of radius foot class composition, includes the base, be equipped with the discharge gate on the base, the base top is equipped with and is used for the suppression body with fodder press forming, the suppression body is equipped with the manger in discharge gate corresponding position, be equipped with the blade that is used for cutting the suppression fashioned fodder on the base. Firstly, preparing a gas generating body into a long strip in advance, then penetrating out of the base for 1cm through a discharge port, paving a mixture of traditional fish feed and copepods on the base, then pressing the pressing body, finally pressing and molding the feed at the position of the discharge port, and then cutting off the feed and the gas generating body by adopting a blade. Simple structure and high efficiency.
The invention has the beneficial effects that: the invention provides a fish feed containing copepods, which is added with copepods to increase the ingestion rate, can swim after being put into water and increase the appetite of fishes; in addition, a device for preparing the fish feed with the copepoda components is provided, and the device is simple in structure.

In the figure: the food comprises an edible body 1, a gas generating body 2, copepods 3, an embedded groove 4, a base 5, a discharge hole 6, a pressing body 7, a feed trough 8 and a blade 9.
Detailed Description
The invention is explained in further detail below with reference to the figures and the detailed description:
example (b):
fig. 1 to fig. 2 show a fish feed containing copepods, which comprises an edible body 1 and a gas generating body 2, wherein copepods 3 are arranged in the edible body 1; one side of the edible body 1 is provided with an embedded groove 4, and the gas generating body 2 is positioned in the embedded groove 4; the edible body 1 is of a cylindrical structure, and the gas generating body 2 is positioned on one end face of the edible body 1; the raw materials of the gas generating body 2 comprise sodium bicarbonate and citric acid; the weight of the copepod 3 accounts for 1/5-1/6 of the weight of the edible body 1; the volume of the gas generating body 2 is 1/3-1/4 of the edible body 1.
The principle of the feed is as follows: the raw materials of the edible body 1 comprise traditional fish feed and copepods 3, the copepods 3 are such as daphnia, the gas generating body 2 is embedded in the edible body 1, when the feed is put into water, the density of the feed is smaller than that of water, and the feed floats on the water surface, in addition, sodium bicarbonate in the raw materials of the gas generating body 2 reacts with citric acid to generate a large amount of carbon dioxide, and the carbon dioxide is sprayed out from the opening of the caulking groove 4, so that the feed can 'swim' on the water surface, the false appearance of the living feed is easily caused to the fish, and the appetite of the fish is increased.
Fig. 3 to 7 show a device for preparing fish feed with copepods, which comprises a base 5, wherein a discharge port 6 is arranged on the base 5, a pressing body 7 for pressing the feed into a shape is arranged above the base 5, a feed trough 8 is arranged at a position of the pressing body 7 corresponding to the discharge port 6, and a blade 9 for cutting the pressed feed is arranged on the base 5.
The principle of the device is as follows: firstly, the gas generating body 2 is prepared into a long strip shape in advance, then the long strip shape penetrates out from the upper part of the base 5 through the discharge port 6 by 1cm, then the mixture of the traditional fish feed and copepods is paved on the base 5, then the pressing body 7 is pressed downwards, finally the feed is pressed and formed at the position of the discharge port 6, and then the feed and the gas generating body 2 are cut off by the blade 9.
