Feeding method of selenium-rich crabs

Abstract

The invention discloses a feeding method of selenium-rich crabs. The feeding method of the selenium-rich crabs comprises the following steps of firstly, reducing the feeding density of crabs, feeding 600-800 crabs in each mu of water area and simulating the wild environment; secondly, preparing feed for the crabs by using high-protein living insects, adding 0.6%-1.2% organic selenium in parts by mass into the feed and not adding medicines. By reducing the feeding density, the wild environment can be simulated, so that the growth rate can be increased by over 20%; the high-protein living insects are used as feed, so the content of the protein in the crabs is increased, not only are the nutritive values of the crabs improved, but also the taste of the crabs is more delicious.

Description

technical field [0001] The invention relates to the application field of feeding methods, in particular to a feeding method for selenium-enriched crabs. Background technique [0002] At present, the traditional method of raising hairy crabs has the following disadvantages: one is to raise them in centralized waters, that is, to raise more than 1,000 crabs per mu of water, which makes the living space of hairy crabs relatively small, and its growth rate has not been improved; The hairy crabs raised by this method not only have poor nutritional value, but also the taste is not good, and in order to prevent some diseases of the hairy crabs during the feeding process, it is usually necessary to add certain drugs, which not only reduces its nutritional value again , also makes the eater also ingest these drugs indirectly. Contents of the invention [0003] In order to solve the problems in the above-mentioned background technology, the object of the present invention is to pro...
