Sea Lamprey: Aquatic Life In The Great Lakes

If a lake is cut from the ocean and has no large fish as predators (only dragonflies), then the sticklebacks will have a better chance at surviving and reproducing because the sticklebacks will be better adapted to the environment (presence/absence of a pelvic bone) and have little to no predators. The hypothesis was supported.

In May 1991, zebra mussels were found in the Hudson River. 500 billion of these mussels were found in the course of a year. They looked seemingly harmless, but over time these mussels became a sort of threat. They were destroying the microscopic animals in the river. On the other hand, they also help out by a ton. Here is how the zebra mussels destroyed and helped the river.

THE GREAT LAKES The great lakes are comprised of 5 different fresh water lakes, Superior, Huron, Michigan, Ontario, and Erie. The lakes are situated along the US-Canadian border, touching Ontario in Canada and Michigan, Minnesota, Wisconsin, Illinois, Ohio Pennsylvania, Indiana and New York in the United States. Roughly 34 million people in Canada and the United States live in the great lakes basin, and also 35 000 plants and animals, over 170 of those being fish, inhabit the great lakes (Zimmermann). This significantly large water body holds an estimate of 6 quadrillion gallons of water.

The “Zebra mussel helps lakes”, and even the butterflies from California feed on the non-native plants. This evidence shows that not all invasive species do harm. So in certain cases they do help with nature’s habitats. It might seem that we should let nature take this cause except that in other cases if we let nature take this cause it could cause more harm. There are a lot out there and can take over the ecosystem and could affect us.

Cool, calm crashing waves along the coast of the Great Lakes is an timeless picture many generations have enjoyed. The Great Lakes have the same beautiful views as it does in years past.

The ocean abounds with interesting animals of all shapes and sizes that have their unique appearances and habitats at different depths of the sea. The viperfish is a type of fish that lives at nine thousand feet under water and it is extremely dark down there. At this depth, the faint light that is visible down there helps the viperfish to blend in to hide from predators because they have photophers, little organs that produce light down the side of it, which makes them look invisible to predators. They also have a little lure like object that is over their head that attracts fish by blinking a light. When prey is near it, the viperfish can rotate his head and snatch the prey and eat it.

This is why the animals of SeaWorld are suffering by being inside

For many it’s a first pet, a gift from family, something you won as a prize at a carnival, but for Canadian residents the familiar orange goldfish everyone knows and loves is becoming a serious problem. Some flush them in a hurry because they no longer want to take care of them, others commit them to a porcelain vortex because they believe their beloved fish has passed, and the Canadian Government is issuing a warning now to citizens of Canada to stop flushing their fish. Just a few goldfish with the potential to disrupt an entire ecosystem Goldfish are entering the ecosystem the way that a lot of invasive species end up in an environment they don’t belong, Humans are putting them there. Human interference is one of the leading causes of the beginning of over population of invading alien species. In this case many of the fish are going down drains, and ending up in Canada’s lakes and rivers.

The stickleback fish have gained much attention from evolutionary biologists because of their historic ability to adapt to conditions that were not favorable and to survive successfully in them. They are also able to give researchers insight into how evolution occurs in other organisms. The stickleback normally spawns in freshwater but lives in the salt-water ocean. Long ago when ice melted and receded, the fish were given new possible places to inhabit and they did, expanding their spawning locations to newly formed streams. Eventually, though, the streams were cut off from the sea and the once salt-water sticklebacks were faced with the problem of being stuck in freshwater with no way to get out.1 The presence of sticklebacks in freshwater lakes today shows that somehow the fish were able to still survive even though they were in unfavorable conditions. The question is: how did they do it?

This empties through Crane River, a narrow, shallow outlet into Crane Lake, the greatest fishing water in the Parry Sound District — and that is almost equivalent to anywhere — but there are no trout. Of our happy camp here under the birches and hemlocks it is enough to say the summer girl would call it a dream — and so it seems now. The fishing is all that could be desired for a bob or bottom angler, but surface fishing is at a discount. For bait we had shipped from Toronto a thousand or more dew-worms, a great earth worm of six inches or longer, much like the marsh worm of the south, except they are lighter in color, inclined to be slimy, and not nearly so tough, but if one must use worms, these are of the best.

If the fish are not healthy, that can adversely affect people. People could eat contaminated fish, or people cannot sell the fish because they are contaminated. Some fish may die from the pollution, leading to less fish for catching. Lower populations of fish and other marine life can also cause an imbalance in the food chain. Predators can also be harmed

A killer whale named Tilikum was placed in Sealand and he was expected to perform tricks that he had never done, and if he performed them incorrectly all of the whales were withheld food. “This annoyed the others, so they would rake him with their teeth, causing him to bleed” (Lewis). In the wild, when a dominant orca begins showing aggression the other orca has thousands of miles to swim away and flee the scene. However, these animals are in pools where they do not have that option. Living in these tanks are essentially giving killer whales the image of being monsters.

Without the Sea, they will become endangered, perhaps even extinct.

1. 90-100 million tons are killed and wiped off the planet each year. Consisting of some of the most beautiful creatures on the planet. Fish are a primary food source to 3.5 billion people worldwide and the depletion of the species is leaving millions of people hungry. Over fishing is a huge problem that needs to be stopped.

There are some pretty bad things going on in the Hudson river. Have you ever seen a zebra mussel. Or even let alone heard of these kinds of creatures. Well let me tell you exactly what is going on in the Hudson river. It’s also very sad as well because entire ecosystem is going down with the recent crazy population of the mussels.
