Abstract
The invention relates to a soilless Nereid breeding method. A cement pond is used as a Nereid breeding pond. Sea water undergoes dark precipitation and secondary sand filtration and is then filtered for further use by a 300-mesh bolting-silk bag. Gracilaria is selected as a Nereid perching environment. The breeding pond and the gracilaria are sterilized. The gracilaria is paved at the bottom of the pond. The filtered sea water is added. Yong Nereids with 2-3-meter bodies are put in the pond according to a density of 1500-2000 Nereids per square meter. During the Nereid breeding, chlamydomonas, artificially mixed feed and fish paste are used for feeding the Nereids. Water in the pond is changed each day. The breeding pond is cleaned regularly. The light illumination is controlled in a range of 400-1000 Lux. Meanwhile, as the Nereid grow, the number of the Nereids is added. After 8-10 months of breeding, the Nereid yield rate can reach 5-7 kg/m2, which is 40 percent higher than the traditional breeding methods. The method adopts the gracilaria in place of silt as the Nereid perching place, thereby facilitating the cleaning, reducing a great amount of man power, fully improving the breeding environment, decreasing the possibility of diseases and being good for the growth of the Nereids and the breeding density increase. Meanwhile, the gracilaria can also be sold as commodity.
