More than ever, climate change has made it hard to guess how many fish there are and how many there will be next year or the year after that. Are the fish gone, or did they move?.
The Alaska Department of Fish and Game said earlier this month that the snow crab fishery for this year has been canceled. CNN and other news outlets said that billions of the crabs had “disappeared.” At the same time, the Maine lobster industry was shocked when the Monterey Bay Aquarium’s Seafood Watch program red-listed lobster for the first time. This was because a court had said that the fishery was putting critically endangered northern Atlantic right whales at risk of going extinct. A lot of money is at stake, and reactions have been extreme. How did we get here?.
The U. S. is proud of its management of commercial fisheries. NOAA says every year that most of the populations it oversees are not overfished and that overfishing is not happening. We don’t know enough about 245 stocks to say for sure if they are overfished or not. That leaves 51 stocks that are still overfished. It doesn’t sound very good, but it’s better than it used to be and, I guess, better than a lot of other places. Certainly, the U. S. spends more money and effort on fisheries management than just about anyone else.
The Elusive Lobster: Exploring Alaska’s Complex Crustacean Ecosystem
The frigid, turbulent waters off Alaska’s coastline teem with bountiful seafood options – halibut, salmon, crab, and more. But when it comes to lobster, many assume this crustacean cannot survive in Alaska’s inhospitable climate However, the truth is more complex than a simple yes or no Lobsters do exist in Alaska, but not in the traditional form most imagine.
While technically there are no native lobster species residing in Alaska, some unique varieties have adapted to thrive in its chilly depths And one superstar stands out – the Alaska Spot Prawn. Reigning as Alaska’s unofficial “lobster,” these shrimp impersonators have dominated the market Their large size, hardy shells, and sweet flavor have earned them celebrity status.
However, misconceptions still circulate about Alaska’s complex marine ecosystem Many incorrectly assume true lobsters cannot exist in such harsh conditions But research reveals a more nuanced reality. While rare, small populations of actual lobster species have been discovered in Alaska waters. Their range and sustainability remain questionable as climate change impacts seawater temperatures.
Adding further complexity, not all lobsters share the same thermal limits. Studies on Australian lobster species revealed the variability in temperature preferences between types. The larval stage also showed greater flexibility compared to adults. This suggests single-factor assessments may provide an incomplete picture of potential habitat ranges as ocean warming accelerates.
The life cycle patterns of lobsters add yet another dimension. Their settlements and reproductive success depend on numerous environmental cues, not just warmth. Factors like currents, storms, salinity, and food availability all shape lobsters’ distribution and viability. With climate change disrupting these cycles, predicting future lobster populations in Alaska is challenging.
While true lobsters in Alaska are elusive, one crustacean has cemented its place in Alaskan cuisine. The tasty Alaska Spot Prawn sustains a thriving fishery each summer, drawing droves of eager anglers. Though not a true lobster, its scrumptious sweet flavor and hearty texture earned it local fame as “Alaska’s lobster.” Strict fishing regulations help ensure its continued abundance despite environmental fluctuations.
The intricacies of Alaska’s marine world reinforce the need for an ecosystem-based approach in fisheries management and climate change mitigation. Habitats must be protected on a holistic level. While data on individual species provides clues, the interconnected nature of ocean life necessitates broader strategies. Only by respecting these complex relationships can sustainable seafood supplies be preserved for future generations.
So while classic lobsters remain evasive in the Last Frontier, Alaska still offers bountiful seafood options. And the Alaska Spot Prawn supplies a delicious dose of lobster-like decadence from its crisp northern waters. By understanding each species’ unique niche in the food web, we can responsibly enjoy Alaska’s aquatic riches while safeguarding their continued vitality.
Climate change is absolutely a factor, but so is greed and arrogance.
As a Greenpeace worker, I’ve been in charge of two submersible trips in the Bering Sea. This gave me the chance to see for myself how factory trawlers hurt coral and sponge habitats that are easily damaged. To help protect against uncertainty, we made the case for sanctuaries. This is to make sure that we don’t mess up the ecosystem in a way that hurts biodiversity and the fisheries. As is often the case, the North Pacific Fishery Management Council opposed the idea. Of the 900,000 square miles of ocean under the Council’s jurisdiction, none is fully closed to fishing.
Thousands of miles away in a very different fishery, Maine’s 4,500 lobstermen are grappling with similar challenges. There are some three million lobster pots in Maine’s waters, creating entanglement hazards for whales and other marine life. The lobstermen do not want to kill whales, of course, but with that much gear in the water, whales are being killed nonetheless. The Endangered Species Act, one of our bedrock environmental laws, requires that measures be taken to prevent extinction. So far, actions taken have fallen short of what is needed – or required by law. There are now less than 340 northern Atlantic right whales left, down almost a hundred from just ten years ago.
As with Alaska’s snow crabs, climate change has certainly played a factor. There is evidence that climate change has made whales change their migration patterns so that they go through more fishing areas. Other climate effects have also made the whales’ situation more dangerous.
But the reality is a lot worse than that sounds.
Fisheries management usually focuses on a single species: how many of these things can we pull out of the water while still leaving enough for the population to keep going? This usually means trying to get rid of 60% of the target population, which is what managers hope will be a 20%E2%80%9Cmaximum Sustainable Yield. Many things make this strategy seem crazy, but one of the main ones is that it is very hard to get right. John Shepherd said, “Counting fish is like counting trees, but the fish are invisible and they move all the time.” ”.
More than ever, climate change has made it hard to guess how many fish there are and how many there will be next year or the year after that. Are the fish gone, or did they just move? Have their prey or predators been affected, and what will happen as a result? How does the changing temperature affect their bodies? Do they have more or fewer successful offspring? At the very least, you would think that fishery managers would want to set higher catch limits to account for the uncertainty caused by climate change. They don’t typically do that, but they definitely blame climate change if things go wrong.
That seems to be what has happened with snow crab – and maybe with king crab before that. Trawlers were dragging up enormous numbers of crabs as bycatch, prompting the U. S. and Japan to set aside trawl-free areas as early as 1964. Things stopped being safe, though, in the 1970s. Since then, crabs have had nowhere to hide. As ice conditions shifted and crabs were more exposed, catch limits remained high. King crab populations plummeted, and now snow crab has collapsed as well.
