In 2021, researchers began placing concrete-block oyster reefs in bare eelgrass patches on Prince Edward Island; within two years biomass was about 45 times higher and 45 taxa had colonised the structures

Representative Image (AI-generated) What started as piles of concrete blocks on the seafloor off Prince Edward Island soon became a magnet for marine life. Researchers began installing the artificial oyster reefs in 2021 to test whether they could provide some of the ecological functions lost from areas where eelgrass no longer grew. Within two years, … Read more

Taiwanese students are turning discarded oyster shells and coral waste into 3D-printed structures for damaged reefs

Taiwanese students are turning discarded oyster shells and coral waste into 3D-printed structures for damaged reefs

A group of students in Taiwan has found a way to give discarded shellfish waste a second life beneath the waves. Their project, named Reefvive, takes oyster shells and coral gravel that would otherwise be thrown away and turns them into 3D-printed bases for growing coral. According to the James Dyson Award, the structures have … Read more

Scientists rebuilt oyster reefs in Florida; within 18 months, the wider marine animal community began returning

Scientists rebuilt oyster reefs in Florida; within 18 months, the wider marine animal community began returning

Restoring damaged oyster reefs can bring back the small marine animals that depend on them. A study examined restored, living, and dead oyster reefs in Florida’s Indian River Lagoon to track how their macroinvertebrate communities changed after restoration. The researchers collected 20,087 marine invertebrates representing 41 species from 14 families. Over time, the communities on … Read more

Bette Midler started cleaning a neglected New York park in 1995; 30 years later, her group has planted 200,000 trees and built an artificial oyster reef

Bette Midler started cleaning a neglected New York park in 1995; 30 years later, her group has planted 200,000 trees and built an artificial oyster reef

Bette Midler once spent her mornings clearing parks in Northern Manhattan that the city had all but abandoned. Thirty years later, that early effort has grown into the New York Restoration Project, a charity credited with reshaping green space across all five boroughs. The organisation has planted more than 200,000 trees since 1995, alongside removing … Read more

A Maine oyster farm is testing a solar-powered floating conveyor that moves oyster baskets through water and air; one raft is designed for 125,000 oysters a year

A Maine oyster farm is testing a solar-powered floating conveyor that moves oyster baskets through water and air; one raft is designed for 125,000 oysters a year

3-Dimensional Cultivation of Oysters Automated with Solar Tumbling Engineers and aquaculture experts in mid-coast Maine are testing a solar-powered floating system that could change how oysters are farmed. The platform uses a vertical conveyor to move oyster baskets between coastal waters and the open air.The system, called 3D-COAST (3-Dimensional Cultivation of Oysters Automated with Solar … Read more
