Grass carp is a herbivorous fish that starts grazing when it reaches a body length of about 5 cm. For grass carp weighing over 250 grams, their daily intake of vegetation can range between 125 to 180 grams. When feeding grass carp with fresh forage, several key points should be taken into consideration.
First, it's important to provide fresh, tender, and nutritious grass with low cellulose content. Such grass is easier for the fish to digest and helps them grow faster. Fresh grass should always be used whenever possible. The best options are young leaves and soft grasses with parallel veins. Avoid feeding grass carp with coarse or fibrous plants like nettle-like or broad-leaved grasses. Instead, opt for species like ryegrass, sudangrass, or wild young leafy grasses, which are more palatable and suitable for their dietary needs. Also, pay attention to what the fish prefer to eat—feed more of the types they like to ensure optimal growth.
Second, avoid feeding aquatic plants unless necessary. Research shows that grass carp can gain 1 kg of weight by consuming 15 kg of terrestrial forage, but it takes up to 60–80 kg of water plants to achieve the same result. Therefore, if there's a shortage of aquatic plants, it's better to feed little or no water plants at all.
Third, adjust the type of grass based on the size of the fish. Young grass carp have small mouths and cannot handle tough or coarse feed. It’s recommended to offer soft plants such as water hyacinth or duckweed, or finely chopped long grasses. As the fish grow and their beaks become larger, they can gradually transition to eating more conventional fresh grass.
Fourth, maintain a consistent feeding schedule. Feed grass carp regularly, in sufficient amounts, and ensure even distribution so that all fish get enough food. Spread the forage evenly in the pond to encourage uniform consumption. Adjust the quantity based on weather conditions, water quality, and fish activity levels. Never feed spoiled or old forage, as this can lead to disease outbreaks among the fish. Proper feeding practices are essential for maximizing growth and maintaining healthy fish populations.
Probiotics are a kind of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. Such as organic probiotics powder, Digestive Health Probiotics, Multi-Strain Probiotic Powder, and Probiotic Supplement Powder By regulating the host mucosa and the immune function of the system or by regulating the balance of intestinal flora, promoting the absorption of nutrients to maintain intestinal health, thus producing single microorganisms or a well-defined mix of microorganisms that are conducive to health effects.
Probiotics Powder has many benefits. It's a Nutritional Supplements.
Probiotics can synthesize digestive enzymes. Together with the digestive enzymes synthesized by animals, they participate in the digestion of nutrients in the intestine, stimulate the secretion of digestive enzymes in the animal body, reduce the depth of the small intestine recess, increase the villi height, increase the surface area of the small intestine, and promote the absorption of intestinal nutrients. Probiotics can also be used as Food Additives.
Probiotics' structure, such as peptidoglycan, lipoteichoic acid, and other components, can act as antigens to directly activate the immune system, or stimulate the host immune system through autocrine immune activators, thereby improving the immunity of animals, enhancing the activity of the body's innate immune cells and natural killer cells, activating dendritic cells, and stimulating the body to produce cytokines. And stimulate B cells to secrete antibodies, probiotics can stimulate the gut to produce secretory globulin A (SIgA), and protect body health.
