What feed do carp eat? A detailed introduction to common bait types
Carp generally like to eat soybean meal, wheat bran, fish meal, wheat, and so on. In addition, the nutritional requirements of carp differ at different growth stages. At the fry and fingerling stages, the required feed contains 35-40% crude protein and 10-20% fish meal; at the adult fish farming stage, the required feed contains 30-32% crude protein and 5-10% fish meal.
How is carp feed formulated?
Scholars at home and abroad have carried out much research on the nutritional requirements of carp for feed. The research results show that the protein requirement of carp for feed is lower than that of carnivorous fish such as rainbow trout, and higher than that of plant-eating fish such as grass carp, with a suitable level of 38.5% (Ogino); it can make relatively good use of plant protein sources; it can also make good use of starch. At different growth stages, under different water temperature and water quality conditions, and under different farming methods, the protein requirement and utilization rate of carp for feed also differ. The crude protein content of carp feed in Japan is generally above 39%. In China, the protein content level of compound feed for carp also differs due to differences in region and farming method. Generally, the crude protein content of compound feed at the adult fish farming stage is 28%?35%, and at the fingerling farming stage it is 35%?40%. In ponds with non-intensive farming or at low temperatures, the crude protein content of the feed is lower. Conversely, the crude protein content of the feed is higher. Now, based on data obtained by some scholars on the nutritional requirements of carp feed, and in combination with issues such as China's existing feed resources and feed costs, standards have also been formulated for compound feed at different growth stages of carp, and their nutritional composition indicators are shown in Table 49.
