The Butterfly Peacock Bass is an exotic fish that came from the Amazon River Basin in South America. The Butterfly Peacock Bass was introduced to the U.S. by the FWC (Florida Wildlife Conservation) to prey on other non-native species of fish. The Butterfly Peacock Bass like warm slow flowing canals and waterways so they do not spread fast and have only made it to a few areas in the U.S. They have populated the southern tip of Florida, parts in Texas, and southern Arizona. They move from place to place by either swimming up stream or the eggs of the fish get stuck on the legs of bird and are passed to different ponds and streams. The Butterfly Peacock Bass is a problem because they eat native fish lowering population density and richness of …show more content…
The impact that the Butterfly Peacock Bass has had on the environment is how they have caused a decline in the native fish population and richness that will only grow back in time. They have actually helped our economy though, because people now travel to florida and spend money on trying to catch the exotic fish that they cannot keep. The Butterfly Peacock Bass effects the biodiversity of the ecosystem that they live in, like in Rosana Reservoir in Brazil resulted where they had a 95 percent decline of native fish. They cannot reproduce successfully in cold climates so they haven’t made it far into the U.S. but they still have made it to a few states and have also been found in Virginia where scientist thought they couldn’t populate. They prey on the small native fish and grow to sizes that are about 12 pounds and grow over 100 centimeters in length. They live in areas that are 66 degrees fahrenheit or higher and lower than 18 ppt saltiness.they live in Large coastal canals of southeast
Of course there are many beautiful and dynamic fish that reside in the waters of Hawaii, but none are as captivating as the Humuhumumunukunukuapua'a (Rhinecanthus rectangulus ). This reef trigger-fish is the official state fish of Hawaii because of its abundance in the shallow waters of the coast. Humuhumumunukunukuapua'a means “nose like a pig” because of the shape of its nose due to the formation of its teeth and because it makes a “snorting” sound when abruptly taken from the water and when swimming away from predators. The locals of Hawaii usually call this fish humuhumu (hoo-moo-hoo-moo) in lieu of having to pronounce its full name for conversation purposes. In other parts of the world this shallow water fish is also known as the Picasso and rectangle fish because of the colors and patterns on its body. Since the humuhumu prefer waters with degrees from seventy-five to eighty degrees Fahrenheit they are found and indigenous to the “Indo-Pacific: Hawaiian islands, Red Sea south to East London, South Africa and east through Indonesia to the Marquesan Islands, north to southern Japan, south to Lord Howe Island.”(Oceanlink.com).According to ask a Marine Scientist:Osteichthyes , they are in the class of the “Actinopterygii (ray-finned fishes)”,the order of the ”Tetraodontiformes (Puffers and filefishes)”,a member of the ”Balistidae” family(Oceanlink.com), and its biome of preference is the coastal strand.
The effect of the Everglades in water supply is wildlife. One effect of this is, the water is dirty and unclean with mercury, phosphorus, and other hazardous waste. As a result of that, the water is killing the animals. In passage one it states,”Quantity and diversity of the wetlands wildlife
One of the Bays biggest resources is its oysters. Oysters are filter feeders which mean they feed on agley and clean the water. The oysters feed on agley and other pollutants in the bay turning them into food, then they condense the food down to nutrients and sometimes developed pearls. Filtering the water helps the oysters to grow, and also helps clean the Chesapeake Bay. One oyster can filter 50 gallons of water a day, Oysters used to be able to filter the Bay in about a week. However, these creatures are now scarce in the bay. The Chesapeake Bays Oyster (crassostrea virginica) Population has declined severely because of over harvesting, agricultural runoff, and disease. Now the Chesapeake Bay is becoming polluted without the oysters and the water is not nearly as clean as it once was. The Chesapeake Bay was the first estuary in the nation to be targeted for restoration as an integrated watershed and ecosystem. (Chesapeake Bay Program n/d). This report will show the cause and effect of the Chesapeake Bay's Oyster decline on the Bay.
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.
Every day many species are slowly becoming either endangered or extinct and recently an endangered bird species called piping plovers, started nesting on Revere Beach. What would seem as a miraculous discovery, many are averse to their new inhabitants on the beach. Many Revere residents are complaining because the piping plovers now occupy parts of “their” beach. But in the article “Revere Beach should welcome the piping plover” The Editorial Board believes that the presence of the piping plover could be greatly beneficial to the city of Revere and I certainly agree. What led me to select this particular article is my concern for the many endangered species in the world like the piping plover. Human hands have led many species to become endangered
Fish habitat is the underwater world which many people do not see. It is just like the world that people live. Fish and plants reproduce, eat, and live in this environment, and even face challenges such as invasive species. It is said that “Invasive species are non-native species that threaten the diversity or abundance of native species due to their uncontrollable population growth, causing ecological or economic impacts” (“Invasive” par. 1). Vegetation plays a big role for fish habitat and for a lake itself. Aquatic habitat provides living space for not only fish but also for many aquatic insects. These insects then in turn provide fish and other species of animals with food (“Native” par. 4).
Graphic novels are something that requires a lot of deliberate thought and dedication to create a novel that affects the reader in the way authors want them to. Everything within a graphic novel is conscious decision to enable the tones, story, characters, and messages to get through as best as they can. Due to this it is difficult to create an adaption based on someone else’s work, as you want to portray their messages and tones accurately, but also how the creator interoperates the original authors work. This is a problem I had in the creation of my mini graphic adaption of The Flying Troutmans by Miriam Toews. The Flying Troutmans is about a family going on a trip in America in search of the father of the kids Hattie is in charge of after
The Long Island Sound is an estuary, and is in fact one of the largest in the world. An estuary is a place where salt water from the ocean mixes with fresh water from the rivers that drain from the land. Moreover, like other estuaries, the Long Island Sound has an abundance of fish and other waterfowl that add to the natural balance of the island, as well as one of the most important economic factors (Tedesco). Like other estuaries around the world, the Sound provides breeding, feeding, nesting, and nursery areas for many species that will spend most of their adult lives in the oceans (Long Island Sound Study). Despite these similarities to other estuaries, the Long Island Sound is unique from anywhere else in the world. Unlike other estuaries, the Long Island Sound does not just have one connection to the sea but it has two. It has two major sources of fresh water flowing into the bay that empty into the ocean. It combines this two-...
The Chesapeake Bay is a large bay that stretches from Maryland to Virginia, fed by many rivers and streams that run from as far north as New York to Virginia and West Virginia.5 It is home to a plethora of plants and fish species, many of which the people of the area fish for food and supplies. The pollution present in the Chesapeake Bay is affecting the livelihood of both the fishermen and the fish – the less the fishermen haul due to the death of the species they catch, the less they get paid – and as consumers of these fish, we are consuming the toxins as well.
Since this first encounter I have caught lots of these magnificent fish and as the years go by they seem to keep getting bigger and bigger. I have developed several baits and presentations that help me to catch these fish and I would like to share them with you.
The Black carp originated in many of the Pacific drainage areas of eastern Asia, China, and parts of Russia and Vietnam. Black carp was introduced to the United States in the 1970’s to fish hatcheries and to control the populations of disease carrying snails in ponds. Flooding is the main factor to thank for the release of the black carp, which quickly turned into an invasion of the waterways. The Black carp is a medium size fish with the opportunity to become an extremely large fish if the conditions are favorable. “Based on Asian records, large adults may be more than 1.5 m total length and 70 kg or more in weight”(Nico,L.G). The black and grass carp is close to identical in regard to the characteristics of one another. However, the black carp is a slightly lighter color of black, with extremely large scales on the entire body. A black carp has human like molars as teeth that are used to crush snails and mollusks. With a slightly pointed snout that is a likely adaptation used to filter through the bottom of water bodies in search of food. The physical build of a black carp exhibits the design of a bottom-dwelling feeder. Sporting a long snout, large powerful human molar like teeth the black carp is built to succeed in water full of snails and mollusks. This means that the populations of already near extinct native snails and mollusks are at great risk of being
The Piping Plover is a small, endangered bird. It is otherwise known as the Charadrius Melodus (ES: Piping Plover). It lives, and breeds along the Atlantic coast of Canada, but usually around the Great Lakes, in Canada and the U.S.A (Piping Plover Page). Recently, it has been found in the Wasaga Beach area (Springwater News). This bird has not been seen in this area since 1978, so an area of Beach 1, where the Nottawasaga River enters Nottawasaga Bay was fenced off, and could remain closed until July (Springwater News). It also lives in and around Alberta (ES: Piping Plover). These birds generally live on or close to beaches and lakes, usually places with water. This bird generally likes to be around places with sand, like beaches, because it can blend easily. The bird has a back that is sandy brown in colour, so predators can’t see it (Piping Plover Page). They are constantly losing their habitat to buildings, pollution of lakes and ponds, and clearing of forests.
A poem without any complications can force an author to say more with much less. Although that may sound quite cliché, it rings true when one examines “The Fish” by Elizabeth Bishop. Elizabeth’s Bishop’s poem is on an exceedingly straightforward topic about the act of catching a fish. However, her ability to utilize thematic elements such as figurative language, imagery and tone allows for “The Fish” to be about something greater. These three elements weave themselves together to create a work of art that goes beyond its simple subject.
...ughout much of their continent-wide breeding range is proof that to manage wildlife; you need to manage their ecosystems. Wet weather, combined with abundant nesting cover provided by the federal Conservation Reserve Program, have shown that wetland and grassland ecosystems are what make or break duck populations. The same is true for all other species, game and non-game. (R. Holmes). (1)
Some of the species being threatened by pollution include: dolphins, porpoises, penguins, sharks, and polar bears.
