Qianfan culture in Rushan, Shandong Province: exploring a new way of mixed culture of sea cucumber and sea urchin

A few days ago, the reporter saw in the Qianfan mariculture professional cooperative of fengzishan village, Rushankou town that the breeder was putting the newly arrived shrimp, horse manure and sea urchin seedlings into the sea cucumber breeding pool "Breeding sea cucumbers and sea urchins together is a new way that we explore this year The purpose is to make use of the complementary living habits of the two, achieve the natural ecological balance, and achieve the maximum benefits of three-dimensional breeding." Introduction by Wu Zhigang, head of the cooperative In recent years, in the growth process of artificial sea cucumber, it has been criticized by the market because of its multi-purpose feed In order to change this phenomenon and improve the nutritional value of sea cucumbers, Qianfan mariculture cooperative actively explores a new culture mode In October last year, the relevant leaders of the city and town led the cooperative to visit a breeding company in Dalian to learn how to mix sea urchins and sea cucumbers Because there is much moss at the bottom of sea cucumber culture pool, which has a great obstacle to the growth of sea cucumber, and these moss are the best natural food of sea urchin At the same time, some substances discharged during the growth process of sea urchin are products that sea cucumber likes to eat, which can reduce the feeding of "artificial feed", improve the nutritional value of sea cucumber and save the expenditure of feed The mixed cultivation of the two can achieve the effect of double harvest At the end of March this year, the cooperative introduced 20000 shrimp, horse excrement and sea urchin seedlings suitable for mixed breeding from Dalian into a sea cucumber breeding pool In just over 20 days, the volume doubled, showing a strong growth momentum "Next summer, these sea urchin seedlings will grow up According to the current market price of 60 yuan per kilogram, the income is considerable At present, we are in contact with relevant seafood processing plants to extract the nutritive ingredient of sea urchin, sea urchin yellow, for subsequent processing The extract can reach 800 yuan per kilogram " Wu Zhigang said confidently.
