Abstract

The invention discloses an artificial seedling raising method for the naked square starworm. The artificial seedling raising method aims at the large-scale artificial seedling production of the naked square starworm at present, and provides a method including parent insect cultivation, artificial induced labor, planktonic larvae cultivation and nymph cultivation. The artificial seedling raising technology method realizes the large-scale artificial seedling raising of the naked square starworm, so as to meet the development needs of breeding production.

Description

technical field [0001] The invention relates to an artificial seedling raising method for starworms, in particular to an artificial seedling raising method for naked square starworms. Background technique [0002] Sipunculus nudus, commonly known as "sandworm", belongs to the genus Astrozoa and is a species widely distributed in warm water world. my country's coastal areas are distributed from south to north, among which Beibu Gulf is rich in resources. The square star worm is an economically important species in marine fishery resources, and it is one of the famous seafood treasures. Its fresh products and processed dry products are very popular in domestic and foreign markets. The square star worm has extremely high nutritional value. According to existing literature reports, the dry weight of the square star worm contains 73.77% by weight of crude protein, 17.44% by weight of ash, 5.34% by weight of total sugar, and 0.67% by weight of crude fat. A high-protein, high-ash...
