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.

As Halloween approaches, a spooky campaign aims to clear up the common misunderstandings about some of nature's most feared creatures.

In collaboration with other organizations, Defenders of Wildlife is launching its "Real Scary Movies" campaign, to highlight how animals often vilified in horror stories - like sharks, bats, and wolves - are vital to the health of their ecosystems.

Jane Davenport, senior attorney with Defenders of Wildlife, said she hopes to dispel these myths - many of which she said have been fueled by Hollywood blockbusters, like the 1975 movie Jaws.

"Obviously, a shark attack on a human is a terrifying and, unfortunately, sometimes tragic event," said Davenport. "There's only about 70 unprovoked shark attacks on people every year, all around the world. But on the other hand, humans are killing northwards of 80 million sharks every year."

Davenport said she believes the shark's frightening reputation has contributed to a lack of focus on their preservation, leading some species toward extinction.

The shark-fishing industry defends its practices by claiming U.S. shark fisheries are among the most sustainable, with laws that prevent overfishing and enhance economic value.

The campaign urges the public to make more sustainable choices of seafood and consumer products, and to look beyond the scary imagery - even if it's just for Halloween fun.

For Davenport, the public should recognize that the real "spooky and scary" story is how human activities pose a significant threat to wildlife.

"Species like sharks and bats and wolves are not out there trying to do anything other than than live their lives," said Davenport. "And so, we really need to bring awareness and do some myth-busting, to try to dispel the image that these are creepy, scary creatures."

In the spirit of the season, the campaign will put a unique twist on popular scary movies to highlight the harmful impacts of issues like bycatch - when non-target marine animals are inadvertently hooked or netted by fishermen targeting other species.

It's a different perspective to consider while binging the Jaws series.

California has set a goal to protect 30% of its land and waters by the year 2030, so the Ocean Protection Council is working on which waters should count as protected and is identifying new conservation measures.

A public comment period on its draft framework just ended.

Drew Talley, professor of environmental and ocean sciences at the University of San Diego, said the proposal is on the right track but needs a little more work when it comes to estuaries, where the rivers meet the sea.

"It doesn't look at some of the main threats those systems are facing," Talley explained. "Including sea level rise, degraded water quality and ongoing effects of historical alterations like dams and diking and urban runoff."

The Ocean Protection Council is expected to release its final proposal Dec. 9. Estuaries are crucial habitat for many species. They also buffer communities from floods during a storm, reduce ocean acidification and help fight climate change, since marine plants store a great deal of carbon.

Kerstin Wasson, research coordinator for the Elkhorn Slough National Estuarine Research Reserve near Monterey, said the contours of protected areas need to be widened, to account for the effects of climate change.

"With accelerated sea level rise, they're going to need a lot of space to migrate upwards," Wasson urged. "If we were to draw a circle around an estuary to say what's protected, it needs to be 10 feet above where the marsh is today."

More than 90% of California's historic wetlands have been lost to development.

Anglers along the Atlantic coast want stricter regulations to help improve stocks of Atlantic herring, a forage fish vital to a healthy ocean ecosystem.

The population was once depleted from decades of overfishing and has struggled to recover, affecting the health of larger, prized fish up the food chain.

Rich Hittinger, first vice president of the Rhode Island Saltwater Anglers Association, said it hurts local fishermen and the small coastal businesses that support them.

"We see the striped bass and the other fish not showing up in an area," Hittinger observed. "Because the forage fish aren't there."

Anglers have asked the New England Fishery Management Council to reestablish a 12-mile offshore buffer zone for large herring trawlers. Nearly all respondents to a recent public comment period backed further actions to protect the Atlantic herring and other forage fish.

A recent assessment of Atlantic herring stock showed little progress has been made in rebuilding the population. Despite increased management, federal regulators say the likelihood of meeting stock targets for next year is less than 1%.

Jaclyn Higgins, forage fish program manager for the Theodore Roosevelt Conservation Partnership, said she is concerned the science driving harvest restrictions of forage fish has not caught up with what is happening in the ocean.

"We really want to make sure that we use all of the information that we have to move this ecosystem-based management framework forward," Higgins urged. "Improve the models, improve what we have, and not stay stagnant with the status quo."

Higgins noted the Atlantic herring stock currently sits at just 26% of its biomass target. She is hopeful more data collection and research funding will lead to regionally specific and precautionary measures to better protect fisheries and the communities they serve.
