Abstract

The invention discloses a Portunus trituberculatus larva cultivation forage. The forage is prepared by using the following raw materials, by weight, 15-25 parts of spirulina powder, 5-15 parts of shrimp powder, 1-5 parts of yeast powder, 1-5 parts of Bacillus subtilis powder, 1-5 parts of oyster shell powder, 0.1-0.5 parts of trace elements, 0.1-0.5 parts of mineral matters, 1-5 parts of a feeding promoting agent and 17-25 parts of soybean milk. Spirulina in the forage is a Portunus trituberculatus larva's favorite planktonic alga, so the forage accords with the feeding characteristic of Portunus trituberculatus; the yeast powder and the Bacillus subtilis powder can adjust probiotic florae in the intestine of the Portunus trituberculatus and enhance the irritability and the self immunity of the Portunus trituberculatus; and the feeding promoting agent is a purely natural plant pulvis, contains no additives, is in favor of improving the appetite of the Portunus trituberculatus, and has a substantial increase effect on the growth rate of the Portunus trituberculatus. After the forage is eaten by the Portunus trituberculatus, the survival rate and the body weight of the Portunus trituberculatus are substantially improved.

Description

technical field [0001] The invention relates to a feed for Portunus trituberculatus, in particular to a feed for cultivating Portunus trituberculatus larvae, belonging to the field of feed processing. Background technique [0002] Portunus trituberculatus ( portunus trituberculatus ) belongs to Crustacea, Decapod order, Portunidae, is the largest and most famous marine crab in my country. Portunus trituberculatus has delicious meat and rich nutrition. Since the 1980s, its value has doubled. Most of the Portunus trituberculatus caught in my country every year is used for export to earn foreign exchange, and only a small part is provided to the domestic market. Due to overfishing, the natural resources of Portunus trituberculatus are increasingly scarce, and the annual catch is even more difficult to meet the needs of the domestic market. . In order to make up for the shortage of natural resources and meet the needs of the domestic market, artificial breeding of Portunus tri...
