Restoration Project

Korea Fisheries Resources Agency (FIRA) - South Korea

Restoration Objective:

Seaweed forest restoration has been undertaken by FIRA to restore barren grounds and to enhance coastal productivity, species diversity and fisheries resources.

Site Selection Criteria:

Sites are selected that are currently barren grounds, but that historically were inhabited by kelps.

Cause Of Decline:

Urchin grazing caused decline of Saccharina kelps.

Key Reasons For Decline:

Multiple

Site Observations:

Observation Date

1st Jan 2009 – 1st Jan 2019

Action Summary:

Marine seaweed forests were created using various techniques such as anchoring pore bags to supply spores, transplanting ropes with juvenile plants attached onto artificial seaweed reefs, and removing grazing herbivores.

Lessons Learned:

This study grouped all regions of Korea.

Project Outcomes:

Survival rates were not well reported but previous conversations with managers suggested a 50% survival rate by reef.

Key Reasons For Decline:

Multiple
