Carp are commonly known to be heavy bodied, covered with scales and are often thought to be a boney fish. The invasive carp that are affecting the United States primarily come from the eastern side of Asia (inv 4). Although the species are classed together as Asian carp, these fish differ in a number of ways. Common carp (Cyprinus Carpio) were the first of the invasive carp to be brought into the United States in the 1870’s (effects of rapid). These fish are benthivorous and are known to effect the vegetation and the turbidity of the water (effects of rapid). Grass carp (Ctenopharyngodon Idella) were the second to land in the United Sates. In 1963, the grass carp, primarily herbivores, were brought into the Alabama and Arkansas. These fish can grow up to 55” and can weigh as …show more content…
Black carp (Mylopharyngodon Piceus) can grow to 6’ long and weigh as much as 220lbs. They were brought into the United States for pest control in aquaculture, since they feed exclusively on molluscs, and made their way into the wild in 1994 when floodwaters overcame aquaculture ponds (inv 4). Bighead carp (Hypophthalmichthys Nobilis) can grow up to 56” and can weigh as much as 143lbs. They were found in open waters in the 1980’s and escaped their aquaculture habitats in 1994, in the same floods as the black carp. The bighead carp are filter-feeders and were brought into the United States to maintain water quality in aquaculture. Now they are one of the more aggressive invasive species and are popular targets for bow-fishing (inv 4). The last Asian carp that was introduced into the United States was in 1973 and is one of the aggressive invasive species. The silver carp (Hypophthalmichthys Molitrix) is a filter-feeder mainly consuming phytoplankton and zooplankton. These fish can grow to a length of 55” and a weight of 99lbs. Silver carp have been a danger to boaters because of their response to leap out of the water in response to the boats
One species in particular, the Round Goby (Neogobious Melanostomus), is particularly harmful. This is a freshwater fish that originated from the Europe and Asia area, mostly residing in the Caspian and Black seas. The round goby was most likely introduced into this area by accident. It was brought over by ships traveling in the ocean to the Great lakes region. The first big outbreak of the round goby was found in Lake Michigan, with large amounts now found in Lakes Huron and Erie. Round gobies have only been noticed in the Great Lakes Region since about 1990. By 1994 they were found in many bays and rivers outside of Cleveland. Most of the goby sightings have remained in the Midwest.
...d when transoceanic ships drop anchor in freshwater ports. They have become an invasive species in North America, and as such they are the target of Federal policy to control them, for instance in the National Invasive Species Act (1996).
Bass fishing, at present, is considered as America’s number one freshwater sport, its industry is in fact seventy percent higher in growth compared to other types of fishing activities. Bass is a fish that belongs to the Serranidae family or sea basses and the Centrarchidae or the black basses. This family of perchlike fishes are large and oblong with compressed bodies that dwell in warm and temperate seas throughout
This vegetation also provides much cover for fish. The aquatic plants provide a great source of food supply and act as a nursery for young fish (“Native” par. 5). Vegetation serves many purposes in fish habitat; besides keeping fish safe. It also helps keep the lakes clean. Aquatic plants cycle the water and help absorb pollutants. Another great benefit of these aquatic plants are that they help hold sediment and the banks of the lakes in place while providing oxygen into the water (“Invasive” par. 7-8). Unfortunately invasive species are destroying such vegetation. The Common Carp or “Cyprinus carpio” is one such fish that is causing great damages to lakes all around the world.

There are several different theories regarding how they were introduced into the United States. One suggests that they were introduced by fish owners who improperly and illegally disposed of their unwanted fish
In 1831, Asian carp were brought over as a delicacy. Asian carp are originally from Asia (Barbara A. Somervill 13). They were imported by catfish farmers in 1963 for federal research on controlling aquatic vegetation. In 1966, the first Asian carp had escaped into Arkansas waters. By 1970, grass carp we're being stocked in Arkansas waters to help with over vegetation. In 1972, big head carp were brought in the United States by a fish farmer in Arkansas to improve his water quality and fish production. In 1973, silver carp were introduced for phytoplankton control (Watershed Council 1). Over time, they were brought over for different reasons and made their way into many of the United States waters. The federal government had transported the invasive species to help the waters but, they did not realize the bad effects that the fish would have on the future environment. People need to find a way to stop them before it’s too late. Their rapid breeding has had a great toll on the environment and is still affecting it today. Over population can destroy the environment
As reported by the USDA (United States Department of Agriculture), Eurasian milfoil, which is native to Europe, Asia, and Northern Africa, was most likely accidentally introduced to the United States through ballast water, which is water from other places that is dumped into another body of water to aid in stabilizing a ship. The aquatic species are oftentimes trapped in these ballast waters and are released with them into new and unknown environments. This can lead to rapid growth of the invasive species and can become an endangerment to other organisms that...
Fuller, P.J. Schofield, M.E. Neilson, A.J. Benson, and J. Li.). The grass carp is a species that is easily recognized while on the water or near the water. Silver on the sides that darkens towards the top of the fish that runs the entire length of the fish. “The dorsal fin origin is anterior to the pelvic fin origin and it has a short caudal peduncle” (Nico, L.G., P.L. Fuller, P.J. Schofield, M.E. Neilson, A.J. Benson, and J. Li.). The grass carp is typically the smallest in size in comparison to the first three carps. Weighing in at average of fifty pounds. In the past the grass carp species has been introduced to United States waters for the control of biological vegetation. “This species was first imported to the United States in 1963 to aquaculture facilities in Auburn, Alabama, and Stuttgart, Arkansas. The first release of this species into open waters took place at Stuttgart, Arkansas, when fish escaped the Fish Farming Experimental. However, many of the early stockings in Arkansas were in lakes or reservoirs open to stream systems, and by the early 1970s there were many reports of Grass Carp captured in the Missouri and Mississippi rivers.” (Nico, L.G., P.L. Fuller, P.J. Schofield, M.E. Neilson, A.J. Benson, and J. Li). The life expectancy for the grass carp is five to nine years of age. The grass carp is an aquatic vegetarian,
... 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.
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
Invasive species only started to show up in the United States when the Europeans started to arrive. Beforehand, very limited contact was made in this particular region of the world, so very few invasive species came into North America. When the Europeans arrived in 1492, after Columbus discovered North America, they brought their own culture and essential food and animals with them. At first, it was just the basics of maize, wheat, pumpkins, and squash, but later on it also included cows, chickens, and horses . As more Europeans flocked into the country, non-native species began to appear in the area. Often, as non-native species appeared it led to unintended consequences of destroying gra...
Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large species, the cod. In the 1950s the Newfoundland Grand Banks was home to a plentitude of cod; early European explorers said,”that if you lowered a basket into the water, cod will fill it to the brim.” It supplied the locals with an item of trade and a source of food.
When people think of invasive species, they normally do not think of the human species, but why not? There is a large debate about whether or not humans are an invasive species. Before people debate whether or not the human race is an invasive species, they should know the definition of one. The legal definition of an invasive species in the United States is “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health” (Zielinski). The International Union for Conservation of Nature, IUCN, defines an invasive species as “animals, plants or other organisms introduced by man into places outside their natural range of distribution, where they become established and disperse, generating a negative impact on the local ecosystem and species” (Zielinski).
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
