Aquatic Invasive Species Regulations In Michigan
The state of Michigan defines an aquatic invasive species as "an aquatic species that is nonnative to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health".Natural Resources and Environmental Protection Act, Mich. § 324.3301 (1994). http://www.legislature.mi.gov/(S(q2vld4p2rvssxkratijvtmhs))/printDocument.aspx?objectName=mcl-Act-451-of-1994&version=txt. Retrieved April 20, 2021. There are approximately 160 invasive aquatic species residing in Michigan. Some of the most commonly known species are the zebra mussel, quagga mussel, sea lamprey, and several species of Asian carp. Michigan's Natural Resources and Environmental Protection Act (NREPA) is the primary state law regulating aquatic invasive species in Michigan. Background Aquatic invasive species were first introduced to the Great Lakes in the early 1800s through ballast tank water. Freight ships carrying goods from foreign countries ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin ('' Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter ('' Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range ...

Dikerogammarus Villosus
''Dikerogammarus villosus'', also known as the killer shrimp, is a species of amphipod crustacean native to the Ponto-Caspian region of eastern Europe, but which has become invasive across the western part of the continent. In the areas it has invaded, it lives in a wide range of habitats and will prey on many other animals. It is fast-growing, reaching sexual maturity in 4–8 weeks. As it has moved through Europe, it threatens other species and has already displaced both native amphipods and previous invaders. Description ''D. villosus'' can grow up to in length, relatively large for a freshwater amphipod. It varies in appearance, with some specimens being striped, and some not. It has relatively large mandibles which allow it to be an effective predator. Distribution ''D. villosus'' was originally found in the lower courses of large rivers in the Black Sea and Caspian Sea drainage basins. It has become an invasive species across central and western Europe, using the Danu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michigan Law
The law of Michigan consists of several levels, including constitutional, statutory, regulatory and case law. The ''Michigan Compiled Laws'' form the general statutory law. Sources The Constitution of Michigan is the foremost source of state law. Legislation is enacted by the Michigan Legislature, published in the ''Michigan Acts of the Legislature, Acts of the Legislature'', and codified in the ''Michigan Compiled Laws''. State agency regulations (sometimes called administrative law) are published in the ''Michigan Register'' and codified in the ''Michigan Administrative Code''. Michigan's legal system is based on common law, which is interpreted by case law through the decisions of the Supreme Court and Court of Appeals, which are published in the ''Michigan Reports'' and ''Michigan Appeals Reports'', respectively. Constitution The foremost source of state law is the Constitution of Michigan. The Michigan Constitution in turn is subordinate to the Constitution of the United St ...

Invasive Species In The United States
Invasive species are a significant threat to many native habitats and species of the United States and a significant cost to agriculture, forestry, and recreation. The term "invasive species" can refer to introduced/naturalized species, feral species, or introduced diseases. Some introduced species, such as the dandelion, do not cause significant economic or ecologic damage and are not widely considered as invasive. Economic damages associated with invasive species' effects and control costs are estimated at $120 billion per year. Notable invasive species } , - , , , , Giant African land snail , , ''Lissachatina fulica'' , , Florida , , Pest control , , This invasive species was smuggled into Florida from Africa.

United States Coast Guard
The United States Coast Guard (USCG) is the maritime security, search and rescue, and law enforcement service branch of the United States Armed Forces and one of the country's eight uniformed services. The service is a maritime, military, multi-mission service unique among the United States military branches for having a maritime law enforcement mission with jurisdiction in both domestic and international waters and a federal regulatory agency mission as part of its duties. It is the largest and most powerful coast guard in the world, rivaling the capabilities and size of most navies. The U.S. Coast Guard is a humanitarian and security service. It protects the United States' borders and economic and security interests abroad; and defends its sovereignty by safeguarding sea lines of communication and commerce across vast territorial waters spanning 95,000 miles of coastline and its Exclusive Economic Zone.

Ballast Water Regulation In The United States
Ballast water discharge typically contains a variety of biological materials, including plants, animals, viruses, and bacteria. These materials often include non-native, nuisance, exotic species that can cause extensive ecological and economic damage to aquatic ecosystems. Ballast water discharges are believed to be the leading source of invasive species in U.S. marine waters, thus posing public health and environmental risks, as well as significant economic cost to industries such as water and power utilities, commercial and recreational fisheries, agriculture, and tourism. Studies suggest that the economic cost just from introduction of pest mollusks ( zebra mussels, the Asian clam, and others) to U.S. aquatic ecosystems is more than $6 billion per year. The zebra mussel, native to the Caspian and Black Seas arrived in Lake St. Clair in the ballast water of a transatlantic freighter in 1988 and within 10 years spread to all of the five neighbouring Great Lakes.

Marbled Crayfish
The marbled crayfish or (''Procambarus virginalis'') is a parthenogenetic crayfish that was discovered in the pet trade in Germany in 1995. Marbled crayfish are closely related to the "slough crayfish", '' Procambarus fallax'', which is widely distributed across Florida. No natural populations of marbled crayfish are known. Information provided by one of the original pet traders as to where the marbled crayfish originated was deemed "totally confusing and unreliable". The informal name ''Marmorkrebs'' is German for "marbled crayfish". Model organism Marbled crayfish are the only known decapod crustaceans to reproduce only by parthenogenesis. All individuals are female, and the offspring are genetically identical to the parent. Marbled crayfish are triploid animals with 276 chromosomes, which may be the main reason for their parthenogenetic reproduction. It is hypothesized that marbled crayfish originated from an error in meiosis resulting in a diploid gamete, which was then fer ...

Stratiotes
''Stratiotes'' is a genus of submerged aquatic plant commonly known as water soldiers, described as a genus by Linnaeus in 1753. Several specific names have been coined within the genus, but at present only one is recognized: '' Stratiotes aloides''. native to Europe and NW Asia. ;formerly included in genus moved to other genera: ''Enhalus Hydrocleys Ottelia'' # ''Stratiotes acoroides - Enhalus acoroides'' # ''Stratiotes alismoides - Ottelia alismoides'' # ''Stratiotes nymphoides - Hydrocleys nymphoides'' # ''Stratiotes quinquealatus - Ottelia alismoides'' Description The leaves are serrate and very brittle, breaking easily when handled. Reproduction is generally by offsets, which may number five or more per plant. In the UK, male plants have rarely if ever been recorded, although some hermaphrodite flowers have been recorded from more southerly locations. Sexual reproduction is not known to occur. A characteristic of the genus is the habit of the plants rising to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Procambarus Clarkii
''Procambarus clarkii'', known variously as the red swamp crayfish, Louisiana crawfish or mudbug, is a species of cambarid crayfish native to freshwater bodies of northern Mexico, and southern and southeastern United States, but also introduced elsewhere (both in North America and other continents), where it is often an invasive pest. Appearance ''P. clarkii'' is typically dark red, with long claws and head, small or no spines on the sides of its carapace just below the head, and rows of bright red bumps on the front and side of the first leg. Range and range expansion The native range of ''P. clarkii'' is from northern Mexico and far southeastern New Mexico, through the Gulf States to the Florida Panhandle, as well as inland north through the Mississippi Basin to southern Illinois and Ohio. It has also been introduced, sometimes deliberately, outside its natural range to countries in Asia, Africa, Europe and elsewhere in the Americas. In northern Europe, the populations ...

Limnoperna Fortunei
''Limnoperna fortunei'', the golden mussel, is a medium-sized freshwater bivalve mollusc of the family Mytilidae. The native range of the species is China, but it has accidentally been introduced to South America and several Asian countries where it has become an invasive species. It is considered to be an ecosystem engineer because it alters the nature of the water and the bottom habitats of lakes and rivers and modifies the associated invertebrate communities. It also has strong effects on the properties of the water column, modifying nutrient proportions and concentrations, increasing water transparency, decreasing phytoplankton and zooplankton densities, on which it feeds, and enhancing the growth of aquatic macrophytes. Because mussels attach to hard substrata, including the components of industrial, water-treatment and power plants, they have become a major biofouling problem in the areas invaded. Description The larvae of the golden mussel are small (around ), and live in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Yabby
The common yabby (''Cherax destructor'') is an Australian freshwater crustacean in the Parastacidae family. It is listed as a vulnerable species of crayfish by the International Union for Conservation of Nature (IUCN), though wild yabby populations remain strong, and have expanded into new habitats created by reservoirs and farm dams. Other names frequently used for ''Cherax destructor'' include the blue yabby or cyan yabby. Its common name of " yabby" is also applied to many other Australian ''Cherax'' species of crustacean (as well as to marine ghost shrimp of the infraorder Thalassinidea). Yabbies occasionally reach up to in length, but are more commonly long. Colour is highly variable and depends on water clarity and habitat; yabbies can range from black, blue-black, or dark brown in clear waters to light brown, green-brown, or beige in turbid waters. Yabbies specifically bred to be a vibrant blue colour are now popular in the aquarium trade in Australia. During a wet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wels Catfish
The wels catfish ( or ; ''Silurus glanis''), also called sheatfish or just wels, is a large species of catfish native to wide areas of central, southern, and eastern Europe, in the basins of the Baltic, Black and Caspian Seas. It has been introduced to Western Europe as a prized sport fish and is now found from the United Kingdom east to Kazakhstan and China and south to Greece and Turkey. It is a freshwater fish recognizable by its broad, flat head and wide mouth. Wels catfish can live for at least fifty years. Etymology The English common name comes from Wels, the common name of the species in German language. ''Wels'' is a variation of Old High German ''wal'', from Proto-Germanic ''*hwalaz'' – the same source as for '' whale'' – from Proto-Indo-European ''*(s)kʷálos'' ('sheatfish'). Description The wels catfish's mouth contains lines of numerous small teeth, two long barbels on the upper jaw and four shorter barbels on the lower jaw. It has a long anal fin tha ...
