METHOD FOR REARING LARVAL WORM OF FISHING ANGLE WORM

摘要

PURPOSE:To enhance survival ratio of fishing angling worm, by containing fertilized eggs in a rearing water tank and growing the fertilized eggs to larval worms in a culture medium using a material having a specific particle diameter for the culture medium. CONSTITUTION:Fertilized eggs are contained in a rearing water tank and grown in a culture medium using a material (e.g. quartzite, quartz sand, sea sand, mountain sand, limestone, zeolite, blast furnace slag or ceramic) having a particle diameter of 1/20-1/2 based on the diameter of the fertilized eggs for the culture medium and grown into larval worms.
