SEDIMENT IMPROVEMENT METHOD THAT UTILIZE URECHIS UNICINCTUS FRY

摘要

To provide a method for improving sediment, which is able to induce natural increase of fishery resource by discharging urechis unicinctus fry, thereby ultimately contributing to increase of fisherman's income. In the method for improving contaminated sediment using urechis unicinctus fry, the urechis unicinctus fry is mass-produced by an artificial seed method and is discharged to inhabit the contaminated and damaged sediment of coastal region, thereby improving submarine environment.
