An invasive species is defined as a species that isn’t native to a country and has negative effects on our economy, environment, or health. The species I am researching is the Asian carp. Its scientific name is Cyprinous Capario. The Asian carp live in many different areas around the United States, such as the Great Lakes area and the Mississippi River. Lake Michigan is home to very diverse populations and species.
The catching of fish and then salting, drying and marketing of that dried fish is what helped form the basis of the society that the Europeans created in the region. Newfoundland became the largest exporter of salted codfish. Soon after, multinational companies and their industrial fishing methods were introduced. Industrial fishing methods included the frozen fish industry which used trawlers to scoop large quantities of fish including cod fish from the water bodies. To control the overfishing and growing industrial fishing market, in 1977 the Canadian Government introduced a 200 mile management zone but by that time most of the ecological damage had started.
1. Introduction: This report will mainly focus on some adaptation features creatures which live in the lake and wetland freshwater habitat have. 2. The adaptive features of animals: i. Adaptation to live in the habitat lack of oxygen A. Crayfish: Crayfish lives in fresh water stream, which is an aquatic environment.
In the 1970’s, Asian flying carp was brought over to the United States to filter waterways of unnecessary algae and bacteria. Since their introduction, these carp have spread across the country, and are currently wreaking havoc on the environment: outcompeting all native fish species due to their aggressiveness and adaptability. They have also been know to cause damages to property and fatally injure fishermen. This fish was originally imported for a good cause, to benefit the environment; the aftermath was unseen and unexpected. People often get involved in situations not pertaining to them because they believe they are able to resolve the issues, and the baleful impacts left behind from these conflicts are generally not deliberate.
They soon coerced the natives into working on sugar and tobacco plantations as slaves—the conditions were horrendous and life was short and brutal. Because European explorers brought along their native diseases (such as smallpox and tuberculosis), the native population was soon dramatically diminished. This meant that Caribbean plantation owners had to import in African slaves. This rejuvenated the African slave trade, which became an essential part of the global economy. Russian serfdom, however,
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. The world record for this fish is was in Nipigon Riveer in Ontario, Canada back in 1918 a whooping 14 LB Brooke.
Many of the introduced trout resulted in the disturbance of local ecosystems through the competition with or preying upon indigenous fishes. Rainbow trout has been blamed for driving many native species into extinction or endangerment. They have eradicated frog species and threatened many native fish species in a variety of environments, such as the Californian golden trout and humpback chub in the Grand Canyon. As established, eliminating or diminishing aquatic species in a given habitat can have drastic impacts on the entire
Marine aquaculture is the farming of seafood species that are indigenous to the ocean. According to the National Oceanic and Atmospheric Administration (NOAA), “U.S. marine aquaculture primarily produces oysters, clams, mussels, shrimp, and salmon as well as lesser amounts of cod, moi, yellowtail, barramundi, seabass, and seabream.” Although marine aquaculture can take place in the ocean, using cages on the seafloor or in suspended water columns, most of the aquaculture systems in the U.S. are man made on land, using a recirculating system that reduces and recycles water. But like other forms of farming, aquaculture can lead to negative effects on the environment. The impacts vary upon the type of organism being farmed/raised and the type of system being used.
Brown shrimp (Farfantepenaeus aztecus) Introduction: Is a species of marine penaeid shrimps which has an important commercial species in the USA. The species has several common names such as northern brown shrimp; golden shrimp, red shrimp or red tail shrimp. Distribution and habitats: The brown shrimp are found along the USA Atlantic coast from Massachusetts to Texas, and along the Atlantic coast of Mexico from Tamaulipas to Campeche and now been confirmed to occur in the Mediterranean, probably introduced in ship's ballast water. The species may occur at a wide range of water depths from as shallow as 4 meters to as deep as 160 meters. However, their highest densities occur at depths between 27 – 54 m and rarely observed at depths exceeding
There are 9 known species of viperfish known and the most common one is the sloanes viperfish but the one i'm gonna be talking about is the pacific viperfish but they all have pretty much the same characteristic. living habits and appearance The pacific viperfish can go from the depth of 5000 to 250 feet. They are estimated to live for about 30 to 40
