Great Lakes Fisheries - The Nature Conservancy

It's hard to imagine the Great Lakes without weekend fishing trips or the legendary Friday night fish fry. For centuries, a wide range of species have shaped the health of these waters, as well as the communities and cultures that thrived on nearby shorelines.

Yet in the past 200 years, the Great Lakes have been altered by invasive species, historic overfishing, tributary damming, habitat loss and climate change. As a result, the Lakes have lost several mid-level forage fish that were once the foundation of a healthy food web, as they provided food for top predators. This impacts the entire ecosystem of the lakes, as well as the commercial and recreational fisheries that are dependent on healthy fish populations. Management agencies have made great progress to check, reverse or compensate for these losses, but there's still work to be done to protect Great Lakes fish for nature and people.

The routine eye-lift was nearly complete when suddenly the patient awoke, suffocating, and began to flop about on the table. The audience gasped. Knowing time was of the essence, the surgeon scooped up the patient in his arms, raced across the stage, and dropped her into a tank of water. She revived. Because she was a fish. Yes, fish eye-lifts exist. As do fin jobs and tail tucks. The operating theater was a mall in Jakarta, Indonesia, where a pet expo was under way. As for the patient, she survived, her formerly droopy eyes now bright and perky. A good thing, too, as this was no ordinary goldfish but rather an Asian arowana, the world's most expensive aquarium denizen, rumored to sell for as mu

Reviews: Horrified SeaQuest Aquarium Visitors Tell All | PETA - PETA Reviews: Horrified SeaQuest Aquarium Visitors Tell All | PETA - PETA Posted: 21 Sep 2020 12:00 AM PDT SeaQuest aquariums—which are owned by Vince Covino—are plagued by issues: animal deaths, legal violations, injuries to employees and members of the public from direct contact with animals, and customer reviews that'll make your jaw drop (and not in a good way). So if you've ever considered visiting a SeaQuest location or any other Covino-operated aquarium, do yourself and animals a favor: Learn from these TripAdvisor and Yelp reviewers. At SeaQuest Folsom in California, an otter was apparently whacked with a broom. "This place smells the animals look tortured and starved. I'm not a fan of this place. Took my family and we ran out of there. … We will never go back. Also we saw an employee wack an otter with a broom. … If you love animals you will hate t
