In aquaculture, fish breeding occupies a pivotal position. To ensure the healthy growth of fish, in addition to paying attention to key links such as fish species, fry, water environment and disease prevention, scientific feed preparation is also indispensable.
Because reasonable feed preparation is the fundamental guarantee for the normal growth of fish. If the feed is not prepared properly, its impact can be far-reaching: at the least, it will hinder the growth of fish, and at the worst, it may cause the loss of the entire fish pond. Next, we will explore the scientific preparation and practical technology of fish feed in depth.

When formulating feed formulas, it is necessary to comprehensively consider the type of fish being farmed, the growth stage, and the proportion of key nutrients such as protein and energy in the feed. It is necessary to ensure that fish obtain the necessary protein to support their growth, and to maintain a balance between energy and protein to avoid imbalance in the proportion that affects fish health. At the same time, it is also necessary to weigh the nutrition and capacity of the feed, to ensure that the fish have sufficient nutrition, and to avoid overeating. It is worth noting that protein feed is usually more expensive than energy feed. Therefore, in the preparation process, it is necessary to avoid excessively increasing the proportion of energy feed to save costs, thereby reducing the proportion of protein feed, which may increase the overall feed cost.
When selecting feed raw materials, the principles of high quality, low price, stable supply and convenient transportation should be followed. In order to ensure the balance of amino acids in the feed and meet the needs of fish for various amino acids, the richer the variety of raw materials, the better. At the same time, it is necessary to avoid the use of moldy and deteriorated raw materials. Although cottonseed meal and rapeseed meal are affordable and high in protein, they contain anti-nutritional factors such as cottonseed phenol and glucosinolate, which may affect fish growth, so the amount used should be limited, generally not exceeding 10%.
