Snakehead Fish Research Paper

Copperhead snakes who are female can reproduce asexually as well as sexually. I think that reproducing asexually is best for the species. Asexual reproduction is when one parent creates an offspring from themselves. There is no mating or mixing of genetics. Generally, there is no variation from generation to generation in population. Sexual reproduction is when two parents, a male and a female, create an offspring through sexual reproduction. While producing sexually would mean that they have different DNA from their parents and therefore wouldn’t have any diseases or hereditary issues passed down I still think asexually is more favorable for the copperhead snakes. Copperhead snakes are targeted because they can pose a threat to humans and therefore could very likely have their

An invasive species has entered Maryland’s waters and threatens to dramatically alter the balance of the aquatic ecosystem. The Northern Snakehead fish, native to Asia and Africa, is a voracious predator, competing with native fish at all stages of its life. The juveniles will consume zooplankton, insect larvae, small crustaceans and other fry fish. Adults eat fish, crustaceans, frogs, small reptiles and even birds and mammals. Snakeheads aggressively protect their young. They are also air-breathers which allow them to survive on land for as long as four days and migrate up to a quarter mile over land making control difficult. Snakeheads carry a disease, Epizootic Ulcerative Syndrome, and there is concern this disease may be transmitted to native fish. The snakehead fish was probably intentionally released in the U.S. by aquarium owners and through the live food fish trade attempting to establish a local food source. To date, the snakehead fish is found in seven states with reproducing populations documented in Maryland and Florida. In Maryland, they have been captured in the Potomac River and tributaries. The Maryland Department of Natural Resources (DNR), the U.S. Fish and Wildlife Service, and the Biological Resources Division of the U.S.G.S. are all involved in monitoring and eradicating the snakehead fish. Maryland anglers can help by learning to identify the snakehead fish and by removing it from the ecosystem. As further incentive, Maryland DNR has offered

An endangered species is a species of either plant or animal that is in serious risk of becoming extinct. This name became connected with the Chinook salmon (Oncorhynchus tshawytscha) in 1994 after being petitioned to be put on the list for nine years (NOAA). There are two main reasons behind the endangerment of the Chinook salmon: over exploration, and dams. Since the times of the Native Americans, Chinook salmon have been highly sought after as a food source. Since then the salmon have experienced great amounts of overfishing. Along with water demands which has resulted in overuse of water and diversion of water had affected spawning sites and loss of habitat putting further strain on their habitats (National Wildlife Federation).

Once the snakes are caught, they go through a few different processes. First, they have their venom removed from

Ring-neck snakes live in various habitats. However, they prefer areas with damp soil and temperatures between 27 and 29 degrees Celsius. Mostly, their habitats are grasslands, rocky hillsides, coniferous forests, farmland, chaparrals, and mixed woodlands. Ring-neck snakes also like hiding, so most of the time they can be found beneath stones or barks from dead trees.

They do not think what the snake is going to do the actual native animals. It kills a whole bunch of species.

Snakeheads are capable of spreading to many different areas and habitats. They do this by swimming underwater into other waterways. Snakeheads also have the ability to breathe out of water, so they can travel short distances on land to get to different areas. Even though snakeheads only breed when temperatures are warm, their eggs only take 1 to 2 days to hatch; causing quicker births of individuals.

The Northern Snakehead, Channa argus, is a freshwater fish species native throughout eastern Asia but can be found worldwide due to incidental and purposeful introductions. In the United States there are many reports of several species of snakeheads that have been sold through aquarium trade in pet stores and purchased from live food fish trade (Maryland DNR, 2003). There are a total of four species of snakeheads that have been introduced in the United States: Northern snakehead (Channa argus), blotched snakehead (C. maculata), bullseye snakehead (C. marulius), and the giant snakehead (C. miicropeltes) and have though to been introduced through intentional releases from pet stores or accidental releases from the live fish trade (Maryland DNR,

Invasive species are a potential critical problem. They can influence the environment completely; anything from individual species to entire ecosystems. The brown tree snake was at first located in Indonesia and New Guinea, but the brown tree snake became an invasive species to Guam by coincidence (3). Because the Brown tree snake is very capable to hide in confined spaces it is believed that they were distributed to Guam by U.S military ships during their war against Japan (5). The brown tree snake can be easily distinguished by its brown, greenish colour, rear fangs and a large, almost disproportioned, head compared to its body (5).

Signal crayfish (Pacifastacus leniasculus) is an invasive species in UK and European freshwaters which originate from North America and was introduced in Europe in the 1960s. Due its large size body and aggressive nature has threatened the native species, white-clawed crayfish (Austropotamobius pallipes). Aggressive behaviour is bolder in signal crayfish species, which is directed also against conspecifics not only against other species (Pintor, Sih and Bauer 2008). Signal crayfish is widespread across the British Islands; predominantly inhabiting south-west part where for the first time was introduced. The motility of signal crayfish depends of temperature, and is higher during the summer period (Bubb, Thom and Lucas, 2004). Signal crayfish

The St.Lawrence river is a large tourist attraction for northern New York. With invasive species being introduced to the river and the land surrounding they have affected the way the river looks and the species that are in it. Any plant or animal found outside of its normal range is considered to be invasive to the area it is now located. There has been an estimated 163 invasive species that have been discovered in the Great Lakes and the St.Lawrence since the late 1800’s. Of the 163 species that have been unintentionally introduced to the area, 85 of them reside in the St.Lawrence river. The variety of non-native plants and animals in the St.Lawrence river and surrounding land have had a continuing negative effect on the native ecosystem.

The first time I felt the recoil of a shotgun coincide with the simultaneous drop and flop of a turkey I knew I was hooked. This was all the way back in the fall of 2005 when I shot my very first turkey alongside my father. That day started an addiction that has since intensified and spread to not only turkeys but almost all of Missouri's highly sought after species. Hunting, conservation, and the great outdoors have always been embedded in the hearts of my family. I am no different and plan to dedicate my life to Missouri’s wildlife the same way they have.

Often in Pennsylvania many people walk passed one of these 3 types of snakes without being aware they are in their presence. In Pennsylvania there are very few, but extremely venomous snakes. With all of them living in varied habitats, these snakes are found throughout the entire state. These 3 snakes are the timber rattlesnake, the eastern massasauga, and the copperhead (Pennsylvania Fish & Boat Commission). The venom these snakes contain can be very dangerous and harmful and they can all affect the organism bitten in many different way. Many symptoms may show after being bitten and there are various treatments to help overthrow the effects of the venom.

The Bighead and Silver Carp are invasive species that were imported by China to control food. They mainly affect the food supply resulting in less sport fish. There isn't a whole lot of Big Heads and Silver Carp, but some were caught in the Mississippi River.
