With news of more large-scale fish dumps in coastal Louisiana waters in recent weeks, advocates are calling for more regulations on the menhaden industry.

Three large commercial fishing nets were dumped in waters off Cameron Parish in separate incidents between Sept. 11 and 14, resulting in an estimated 850,000 dead menhaden, also known as pogies, along with other species of bycatch. This comes one year after a similar incident when a pogie boat cut loose a net containing nearly 1 million fish and set it adrift in the same waters.

David Cresson, executive director of the Coastal Conservation Association of Louisiana, said with locals again seeing large amounts of dead fish washed up on area beaches, the scale and effects of industrial harvest demand more regulation.

"They set these nets 10 or 12,000 times a year," Cresson explained. "They catch a billion pounds of pogies, tens of millions of pounds of bycatch. So, what we saw from September 11th to September 15, was just a tiny glimpse of what's really going on all year long."

Two foreign owned commercial operators, Daybrook Fisheries and Omega Protein, are responsible for the dumps, which state officials cited for failing to report the incident within the permitted time. Neither company responded to a request for comment.

Menhaden are small baitfish harvested for use in a number of products, but in the wild are the basic forage fish for many species. Larger fish following menhaden to feed are often caught in purse seine nets as bycatch. Cresson noted other finfish affected include Red Drum, Speckled Trout, Croakers and Jack Crevalle, but he added it does not stop there.

"It is a long list of species, not just fish by the way, marine mammals, birds, and plenty of other fish and wildlife are impacted by this style of harvest," Cresson outlined. "It's a very industrialized style of harvest that's not allowed anywhere else in the Gulf of Mexico as close to the shores as we allow it in Louisiana."

A quarter-mile buffer zone went into effect across the Louisiana coast this year, but it is the narrowest buffer among the nearby Gulf states. Advocates originally argued for a 1-mile buffer zone citing the need to protect habitat and spawning areas as pogie boats disturb the seafloor when fishing in shallow waters.

Chris Macaluso, director of the Center for Marine Fisheries at the Theodore Roosevelt Conservation Partnership, said the 1-mile buffer zone makes sense.

"It's not just some random effort to penalize a company," Macaluso pointed out. "It's an effort to protect shallow water habitat and minimize the impact of dragging those nets along the bottom, of the boats going into those shallow waters, and also to protect the fish that are in that close-in range."

He stressed a scientifically-based catch limit is also needed to help ensure the long-term viability of the Louisiana fishery.

A new marine national monument in the Atlantic Ocean aims to protect one of the most biodiverse spots on the planet from overfishing.

Located 130 miles off Cape Cod, the area spans more than 3 million acres and is part of the Biden administration's plan to conserve at least 30% of U.S. lands and waters by 2030.

Keith Shannon, Northeast chief of public affairs for the U.S. Fish and Wildlife Service, called the monument a "living laboratory" of pristine ocean habitat.

"Dolphins, multiple whale species and sea turtles and seabirds," Shannon outlined. "It's considered the Serengeti of the sea. There's so much wildlife out there."

Officially called the Northeast Canyons and Seamounts Marine National Monument, Shannon said it contains areas deeper than the Grand Canyon and taller than the Rocky Mountains, and will be safeguarded for years to come.

Debate over how to manage this vast marine environment has been ongoing. Former President Donald Trump lifted restrictions on commercial fishing in the monument area in 2020. The Biden administration reestablished protections one year later, in a move praised by environmental groups and condemned by fishermen, who said it would put more people out of work.

Shannon pointed out the new monument management plan helps ensure the unique area is protected from the harms of overfishing while the larger ocean ecosystem benefits.

"That should allow for species that are fished to come into the monument waters, breed and create more species in the areas outside the monument," Shannon explained.

The monument contains an abundance of phytoplankton, fish, squid and shrimp that serve as vital links in the marine food chain. New federal data show while some recent progress has been made in rebuilding fish stock in U.S. waters, nearly 50 species including Atlantic cod and mackerel remain overfished.

The public comment period is now open on California's new framework for deciding which managed areas within coastal waters meet the definition of "conserved," and where protection improvements need to be made.

California's goal is to preserve 30% of state lands and waters by 2030. The Ocean Protection Council released science-based guidelines this week on what counts as "conserved."

"An area is considered a conservation area if the lands and coastal waters are durably protected and managed to sustain functional ecosystems, both intact and restored, and the diversity of life that they support," said Jos Hill, project director at the Pew Charitable Trusts.

People can weigh in on the process at a series of upcoming workshops in Arcata, Monterey and San Diego. The Ocean Protection Council will also hold two webinars this summer and will accept feedback by email.

Hill said the new framework will be used by the state to evaluate protections in marine-managed areas. The state's "30-by-30" policy sets goals to improve biodiversity, public access and climate resilience.

"The stakes of failing to protect nature are high, and the loss of biodiversity undermines the ability of ecosystems to function and support a healthy environment," Hill said. "And this is particularly important in a changing climate, in which loss of biodiversity reduces nature's resilience to change."

The evaluation criteria will be finalized in the fall and the preliminary decision on which places qualify as conservation areas will be presented in December.

Groups in Connecticut are preparing to celebrate World Fish Migration Day on Friday.

The biennial event celebrates migratory fish species and their importance. It also highlights challenges these species face, such as climate change. Warming waters make it harder for them to survive.

Rhea Drozdenko, a river steward with the Connecticut River Conservancy, noted that planting trees on river banks can reduce water temperatures. She said dams also pose a challenge for fish.

"They are essentially blocking off a river," she said, "so fish that might have historically been able to go far north, up through our watershed, now that there's dams there, they are now blocked. And so, now they have smaller and smaller habitats at their disposal."

She said conservation groups advocate for safer passage with fish ladders and fish elevators at the dams. Another way is removing so-called "deadbeat dams" that no longer serve an economic use and impede fish migration.

Habitat neglect is another problem for migratory fish species. Steve Gephard, a Connecticut River Salmon Association board member, said he has found that if the habitat isn't suitable, migratory fish won't prosper. He said work is being done to restore important habitat areas.

"In some cases, it means putting rocks back in, putting woody debris back in, revegetating the flood plain, putting some curvature in the stream," he said. "A lot of streams, as they've gone through human areas, have been channelized."

Some habitats get degraded through industrialization and by clear-cutting forests. Data show hundreds of miles of fish passageway reopened between 1999 and 2018. If pathways for fish migration open up by removing dams, Gephard said, environmental groups have to ensure healthy habitat is there for these fish to return to.
