Lake Sturgeon
This creature can grow up to 7 plus feet and can weigh up to 300 pounds. They are rarely seen in the great lakes, however, this is their natural habitat. These fish often live on the bottom of the lake and often coast the shoreline. This particular type of fish tries to avoid salt water because they can get eaten by larger fish like sharks. This fish is typically solid dark brown in color with a bright white belly. The Lake Sturgeon was once apart of the major northern lakes like the Great Lakes, Hudson Bay, and the Mississippi River.¨ They also have been found in 19-20 different States. These fish are sometimes referred to as ¨Freshwater Monsters¨¨ (http://www.britannica.com/animal/sturgeon-fish) . The Sturgeon is a very large fish and it doesn't have many predators the only other large fish that can kill it is a large shark or killer whale. The Lake Sturgeon stays in fresh water most of the time, they mate in rivers and when they lay their eggs in the rivers they leave them in rocky areas. When the eggs hatch they float downstream for miles and miles until the larva can grow a tail and swim upstream .When they grow their fins and can swim upstream they usually end up in

If the larva survives when it hatches then their lifespan is about 100 years but most larvae don't get old enough to mature and reproduce. With these fish dying off before they can mature and reproduce, this is a reason why this type of fish is endangered.The number of fish have declined by 75% in the last century. The lake sturgeon reproduce late in the season but they live a longer lifetime than most species of fish. The male and female sturgeon are ready for reproduction when they are about 5 or 7 years old. ¨The average amount of eggs that a female carry is about 17,000 and that is 11% of their body weight¨.
In the past, because the glaciers disappeared slowly can make people have a low temperature, clean water during the summer, but at the same time the salmon begin and end their lives. With temperature getting warmer and our glaciers melting, every stage of salmon’s life cycle is getting hurt.
Hey, I didn’t see you there, how are you?I'm just wondering whether or not a big ol' grizzly bear is going to come charging at me at any point in my life, but seeing as grizzly bears are endangered that probably won't happen. In the past, there were thought to be around 50,000 grizzly bears in North America, nowadays they are growing sparse there are estimated to be only around 1800, now not even a 20th of the population in the past. Most of these grizzlies are located in Yellowstone National Park and Alaska, but they can also be found in Wyoming, Colorado, Idaho and Montana. Some are thought to be in Washington.
Since three-forth of the world is composed of bodies of water, it’s natural that a great number of people rely on fishing for their livelyhood or just for their recreation needs. There are numerous of fish species swimming under the lakes, seas, ponds, and rivers. Most anglers consider fishing as the delight in their purpose-driven life, a sport, as they say.
The salmon are all sterile females which are grown in contained land-based systems, therefore they will not be able to breed among themselves or with other fish. So it is unlikely that the fish will have an impact on wild populations.
The Longnose gars reproduction depends on location that the gar is found in. The reproduction does typically happen during the spring or summer months and all dependent on what the water temperature. The female gar will swim into a small, fast moving stream and lay their eggs (Goddard). The Longnose gar eggs are not just normal eggs that most people think of when they think of fish eggs. Their eggs are green and sticky so they can stick to the plants in the fast moving stream (
Great blue herons, Sandhill cranes common yellowthroat warblers, and even Bald Eagles are found wading, fishing, or nesting in the mudflats and reeds of the Lake Erie wetlands. The Lake Erie's marsh is particularly important globally because this is where migratory birds stop on their long journeys including more than 30 species of shorebirds, waterfowl, tundra swans, canvasbacks, red-breasted Mergansers, and songbirds. While birds flock to the mud flats and vegetation, fish spawn in the wetland shallows. With the exception of the Gulf coast, no other region of eastern North America can demonstrate concentrations of avian migrants like Lake Erie’s coastline. 75 to 90% of Great Lakes fish species use wetlands as a nursery ground, allowing species like the walleye, muskellunge, large-mouth Bass, northern pike, and many
... North America, steelheads are found in Pacific Ocean drainage from southern California through Alaska. In Oregon they are found throughout the Columbia River. The major factor causing steelhead population decline is freshwater habitat loss and degradation. This has resulted from three main factors: inadequate stream flows, blocked access to historic spawning and rearing areas due to dams, and human activities that discharge sediment and debris into waterways.
These are spinning reels designed for smaller fish. You would probably use a reels like this for lakes.
About half of the fish species live in groups at some point in their life
• Understand the movement of fish. Since small water bodies have limited oxygen supply, fish tend to stay shallower. On the contrary, fish in larger lakes have adequate oxygen supply; hence, fish tend to stay where there is food. The fish may also stay deeper because the temperature of the deep water is slightly higher.
Another interesting fact about Lake Baikal is that more than 1,700 species of animals and plants live in the body of water. Of the 1,700 species, approximately two-thirds of those animals are unique to Lake Baikal. In other words, nearly sixty-six percent of Lake Baikal’s animals cannot be found in any other body of water in the world (Saving Lake Baikal). Species found in Lake Baikal include arctic grayling, Baikal sturgeon, and freshwater seal. Due to the huge selection and uniqueness of species in the lake many people do not know of or do not see numerous species that exist in our world. 1,700 different species in one lake is...
Freshwater fish are the most diverse type of fish but also the type of fish that is studied the most (Ross 2013). Lakes are one of the biggest bodies of water that freshwater fish succeed. Fish thrive in lakes because the water is high quality, no infestation of nonnative weeds or exotic fish. The environment is perfect for freshwater fish, these include the popular largemouth bass and many species of sunfish. Some other species that live in lakes are Catfish, Gars, Bowfish, Minnows, Perch and Bass (Whitney et al. 2004). Rivers and streams are bodies of water that are important for freshwater to thrive. Streams vary in the topography of their banks and the soil of the band and also the amount of light and shade they receive. The variation brings diversity of fish species. Florida’s stream provides habitats for about one hundred species of freshwater fish. Rivers also have a diverse array of freshwater fish. The Apalachicola River has 83 species of freshwater fish. Many rivers contain many freshwater species that are rare, endangered and
Pacific salmon belong to a group called anadromous fish that includes Atlantic salmon, sturgeon, lampreys, shad, herring, sea- run cutthroat trout, and steelhead trout. These species hatch and live the first part of their lives in fresh water, then migrate to the ocean to spend their adult lives, which may be as short as 6 months or as long as 7 years. When they reach sexual maturity, they return to the freshwater stream of their origin to lay their eggs. Pacific salmon make the round trip only once, but some Atlantic salmon may repeat the cycle several times.
The catfish maintains an advantage over most fish due to its ability to walk on land. This helpful adaptation comes from the pectoral spines which they flex in order to contour to their body in a walking motion. While the adaptation for land walking is impressive the ability to breathe on land is also beneficial. This ability comes from the hills of the fish which have “highly vascularized arborescent organs that act like accessory breathing structures” (Masterson 2007). Their gas bladder is also minimized to allow for stiffening so that the fish do not collapse on the land (Masterson 2007). Along with the voracious appetite of the fish they have other adaptations that make them invasive as well. The fish can survive in waters that most fish cannot such as hypoxic waters or muddy ponds. Along with being nocturnal these survival abilities allow them to invade aquaculture farms and take prey on the fish stock
Freshwater fish and saltwater fish are very similar in a lot of ways, but also have differences between them so you can tell them apart. Marine water (saltwater) equals over 96 percent of the water on Earth and over 70 percent of Earth’s total surface. Freshwater is less than four percent of Earth’s total water and is about one percent of Earth’s surface (Freshwater Fish). Interestingly a few species of fish can live in either freshwater or saltwater, but for the majority, they must live in a specific environment. All species of fish used to live in a saltwater environment until certain geological events (earthquakes, volcanic activity, etc.) occurred, creating conditions that isolated groups of fish. The new habitats, included freshwater, and new food sources caused fish to either adapt, or to die (Lohrey).
