Endangered Native Atlantic Salmon: Salmon Presentation Project (Not a Final Draft) Salmo salar, most commonly known as Atlantic Salmon, was once native to almost every freshwater river connected to the Hudson River. Due to what people have treated salmon during their history, many species have been endangered and even extinct, this includes the Native Atlantic Salmon. When people first came to Maine, Atlantic Salmon was the main source of food to eat. The population was still very steady then, but it wasn 't until the early 1800’s that populations decreased. European colonists in the Atlantic began massive fishing for fish, and Atlantic Salmon was a common victim of these harvestings. Since then people have been overfishing for salmon, making …show more content…

You’re probably thinking that Atlantic Salmon aren 't endangered, and that you can go eat one at a restaurant or get one at a store. Believe me, you aren 't alone when you think that. In fact, many people have the same misconception about Atlantic Salmon, mostly because they haven 't payed attention or haven 't been educated of this dire situation. Well, the salmon that you see in stores are either different types of salmon, or farm raised Atlantic Salmon. The farm raised are different than wild because those are supposed to be raised, then sold to be eaten. It could even be just another type of salmon, like Sockeye Salmon, Pink Salmon, or Chinook …show more content…

Many differences separate Pacific Coast and Native Atlantic Salmon, other than the fact that Pacific Salmon live in the Pacific region and Atlantic salmon live in the Atlantic region. When talking about scientific names, Pacific Salmon have oncorhynchus as a genus, while Atlantic Salmon have salar as a genus. When talking about spawning, Pacific Salmon are semelparous, or can die immediately, Atlantic Salmon on the other hand, can have a 5% chance of living after spawning, we call this iteroparous. Lastly, Atlantic Salmon is only one type of salmon, but Pacific 's vary from Sockeye Salmon to Coho Salmon. Both though are endangered and need help to

Polymorphic Markers in Sailfin Molly at the STR5 Loci Introduction The purpose of this laboratory report is the explain and analyze the process used to determine the heterozygosity and the allele frequency of the SFMSTR5 loci in Sailfin molly, or Poecilia latipinna. Sailfin molly are a species of fish that inhabit fresh and saltwater bodies of water from South Carolina to Texas. The Sailfin molly examined in this experiment were collected from two different locations in Florida. The fish collected in one location are classified as a single population and the fish collected in the second location are classified as a second population.

The first expectation McEwen predicted was that salmon would be a problem in the restoration plan. In his article, McEwen explains, “Salmon need clear, cool, highly oxygenated water to thrive – a description that hasn’t fit the San Joaquin since the 1940s”(1). His claim is that the restoration plan won’t work, since the waters are scalding for salmon. In addition, an editorial from this year, “Salmon belong where they can thrive – not in San Joaquin River”,

They’re bilateral, having or related to two different fish. They relate to the Red Drum and Bass. The typical weight is 10 to 36 pounds, and are usually 12 - 37 inches ( 1 to 3.01 feet ). Habitat they live in North American deciduous forests, tall trees with many water sectors, with a normal temperature of 50* degrees fahrenheit and physical appearances of climate change. Drum Fish don’t live on land, because they’re fish, but instead live in rivers and big lakes with sand or gravel - like material.

The increasing temperature in the Columbia and Snake River Basin will provide less of a habitat range for the cold water species, sockeye salmon. The reason being that if the salmon were to attempt to inhabit these warmer waters the individuals that are unable to physiologically acclimate to these new temperature conditions will die; thus decreasing the relative abundance of the sockeye salmon’s population in these areas. The decrease in the amount of sockeye salmon will in-turn affect the communities and interactions of organisms living in the Columbia and Snake River Basin. b. With an initial population of 500,000 sockeye salmon and only 272,000 making it to the spawning grounds. We are able to estimate that 184,960 of those that make it to the spawning ground were female (approximately 68%).

In reality, the brook trout is highly valued for its taste and size in many fishing industries. It’s population has gone through a steady decline throughout the years. The brook trout has suffered from habitat loss due to urban sprawl and clear-cutting forests, depriving it of its freshwater home. Let’s take a step to conserve wildlife for the future, preserving it for generations to

While otters are considered secure globally, the southwestern stock in Alaska is threatened. According to Alaska's Department of Fish and Game, http://www.adfg.alaska.gov/index.cfm?adfg=seaotter.main "in southwest Alaska, sea otters have experienced a sharp population decline in the last 20 years," while the Southeast and Southcentral stocks have stabilized or increased. In an email exchange with Webber, he told me that the otters washing up were assumed to be non-threatened Southcentral northern sea otters because of the location of where they came ashore. Otters have a unique history in Alaska. They bounced back from the fur trade, that began in the 1700s, that almost wiped them out.

The Salmon River is the longest river running entirely within a single state, and remains the longest contiguous undammed river left within the continental United States (Carrey & Conley, 1978) and it provides approximately 20% of the water in the Snake River and accounts for 70% of the remaining salmon habitat for the entire Columbia River Basin (Tang et al., 2012). After 425 miles the Salmon River merges with the Snake River just north of Riggins in Idaho County. The Salmon River emerges from the Frank Church Wilderness headed west, turns north briefly and then turns west again to form a confluence with the Snake River, dividing the state of Idaho into two different time zones: Pacific Time north of the Salmon River and Mountain Time south

The rivers here had some of the major characteristics for salmon to live a very healthy life. These characteristics being, clear water, cold water, deep pools, clean gravels, good spawning habitat, places to hide from predators, and last but not least many aquatic invertebrates (water bugs.) Something else that was a huge geological advantage for the Mendocino coast was logging. Although it

In addition to birds, plenty of fish can be found in the basin and fishermen frequent the basin in search of Tilapia (3). Tilapia can be found by the hundreds in the basin along with corvina and an occasional striped bass, mullet, croaker, or sargo (3). The endangered pupfish, though rare, also rely on the basin for survival (10). Pupfish are also the only native species in the Salton Sea, thriving in shallow bodies of water with a high salt and heat

The marine conservation society (2015) states that: Tuna belong to the family called Scombridae. Skipjack tuna (scientific name: Katsuwonus pelamis) are medium sized of the tuna family, are oceanic fish and seasonally migrate from time to time, some making trans-oceanic journeys. Skipjack tuna are found throughout the world's tropical and temperate waters. During the day they school on the surface (often with birds, drifting objects, sharks, whales etc.) however at nights are able to descend to depths of 260m. Skipjack tuna are a very fast growing species, maturing at 2 to 3 years old (40cm in length) and live for up to 12 years. They can grow up to more than 100cm and 34kg in weight but are rarely found larger than 80cm and 10kg.

It tends to live in the North Eartern part of the US on colder streams and it's relater to the char. This actually makes it kind of a relative of the lake trout, but not quite a member of the same family. This fish is only found in very wilderness areas which makes it one of the favorite for trout anglers. In the places that is found you can be sure that the water is very clean and the ecology is as close as prestine as you can find it this days.
