ACCRETION PROMOTION MATERIAL OF EGG AND LARVA OF SHELLFISH AS WELL AS SEEDLING COLLECTION METHOD AND AQUACULTURE METHOD OF SHELLFISH USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide accretion promotion materials of eggs and larvae of shellfish in which the safety is high and the economy is superior, and at the same time, a generation rate of a nutrient source is fast, the seedling collection efficiency is extremely high and stabilized, and furthermore, the installation time to environment is not affected by the spawning time.SOLUTION: Accretion promotion materials of eggs and larvae of shellfish comprises a net for separation between unnecessary deposits and shellfish, mantle materials serving as egg laying parts, and an iron delivery part containing leaf mold, carbon materials and iron materials, in which at least a portion of the carbon materials and the iron materials is brought into contact with each other.SELECTED DRAWING: Figure 10
