Italian Divers Revive Centuries-Old Tradition to Help Save European Perch

Researchers, conservationists, and shellfish farmers on both U.S. coasts are starting and studying seaweed farms as a way to soak up excess nutrients in acidic water to help shellfish survive and grow.

The Rwandan government bans fishing on Lake Kivu during August and September for what they call a “Biological Break.” They pause fishing when the climate is best for fish reproduction and growth to ensure the fish population remains stable.

Aquaponics, a soilless method of farming that combines aquaculture and hydroponic techniques, has provided an affordable and adaptable method for growing traditional cultural Mvskoke foods, such as tobacco, pumpkins, corn, pinto beans, honeysuckle, and minara. Grant funding has enabled tribal members to use aquaponic systems to produce crops and fortify food systems against climate change.

The Okanagan Nation Alliance leads a Fish in Schools program that donates fish spawn and the equipment to raise them to elementary and secondary schools near their territory. Thousands of fish raised by the students are released into local waterways during ceremonies at the end of the school year as a part of their efforts to bring salmon back to the area.

By setting aside an area of the Ngao River to be off limits for fishing, several villages in Thailand have seen a revitalization of large barb and carp in their waters. Compared to non-protected stretches of the river, reserves saw more than twice the total number of fish, and catches outside of that protected area have also significantly increased. “These small, community-based reserves can be a really effective management strategy for sustaining their own resources and conserving fish,” says a researcher at the Global Water Center.

In Jamaica, locally-led coral nurseries are working to restore the coral reef that have been lost to natural and manmade disasters. These organizations have small coral gardens where they can grow free of danger and when they’re big enough, are transported to a reef. With coral and fish being so codependent in the underwater ecosystem, the regrowth of coral has meant an increase of fish and fishing for the country, which many people rely on for their livelihood.

Through a co-management system, which has successfully rehabilitated degraded watersheds, the 2015 Confederated Salish and Kootenai Tribes-Montana Water Rights Compact has restored tribal sovereignty over their waters. This has brought bull trout back to their native streams and reconnected tribal members to traditional lifeways while maintaining water access for existing agricultural users.

Lobster is a crucial economic resource in New England, but entanglements with the fishing line from lobster traps are a major cause of death for endangered North Atlantic right whales. Scientists and lobstermen are testing ropeless, on-demand gear that minimizes the risk for whales and allows fishing to continue in areas that would otherwise be closed for months as the whales pass through.

The Nez Perce Tribe is installing solar panels on homes and community buildings across their reservation with the goal of producing enough energy to replace the hydroelectric dams on the Snake River responsible for the diminishing salmon and steelhead populations.

Nonprofits and coastal communities are popularizing sustainable fishing practices and fishery management to allow ocean ecosystems to bounce back from overfishing and sustain the fishing industry long-term. For example, a community-led organization in Scotland campaigned to create the country’s first “No Take Zone” marine reserve, and a nonprofit in Hawaii is restoring fishponds to revive traditional Hawaiian aquaculture.
