In the 1960s, a species of baitfish called alewife invaded the Great Lakes and started to die off by the millions due to overpopulation. In 1967, the DNR began planting Chinook Salmon, a prolific open water predator, to control the alewife population. In the process, the DNR created one of the best sport fisheries in the world. A fishery capable of bringing billions of dollars a year to the Michigan economy. In recent years the alewife population declined with the last three years being the lowest on record. The DNR had to act fast in order to avoid having the fishery crash, like if did in Lake Huron. The DNR reduced the Chinook Salmon stockings. Reasons the DNR did the right thing is; the alewives will hopefully rebound, Chinook Salmon are not as useful to the lake as other species, and there will be more food for other game fish.…
Did you know that there are four types of Asian carps: The Bighead, Silver, Black and Grass. Most of the concerns are about the Bighead and silver Asian carp. Another fact is Bighead carp grow up to 4 feet long and 100 pounds. And Silver carp grow up to 3 feet long and 60 pounds. The next fact is…
Presently, there’s another species that is not only thought of as less desirable, but actually feared. This is the Asian carp. Asian carp were introduced to the ponds of the Southern United States during the mid 1970’s. This was done to alleviate the problem of the algae that was building up. There are four main species of Asian carp. These include Bighead, Black, Silver, and Grass carp. As a result of flooding, the Asian carp escaped from the ponds and established themselves in the Mississippi River (“Asian Carp Fact Sheet).And now they made there way,into the illinois river system.And now they are, making there way…
Despite this recency of establishment of this species, the zebra mussel has rapidly spread throughout a large portion of the United States. It has been reported from all the Great Lakes and Lake Champlain, the Mississippi River from St. Paul down to New Orleans, the Illinois River, the Ohio River, and many others (National Aquatic Nuisance Species Clearinghouse; Web site at: http://cce.cornell.edu/aquaticinvaders). This spread has produced a number of negative economical and ecological consequences.…
Asian carp is a catchall name for four different carp species, silver, bighead, grass, and black carp (Asian Carp Organization). As we can know from its name, the origin of Asian carp is Asia, and mostly China. The reason of why I choose Asian carp as an invasive species is because Asian carp has totally different treatment in China and America. As a Chinese, I was informed since I was very young that Asian carp is good for both the environment and our health. It contains a lot of proteins and nutrition which can benefit our brain. However, in America, people think it is a disaster to have Asian carp in America.…

Ohio is a great destination for fishing as it provides something for every one of you fisherman out there. Lake Erie is located in the state of Ohio and provides excellent fishing for smallmouth bass. Smallmouth bass tend to appreciate deeper waters unless you are fishing during the spring time, when they move to shallower waters to spawn. During the other seasons of the year, you will mostly find the smallmouth bass in deeper, cooler water with a strong current as they enjoy swimming against it.…
More specifically, aquatic invasive species have the capability to change factors such as water quality, species diversity, and aquatic vegetation which in turn affects industries that depend on that ecosystem. The United States has had 138 invasive aquatic species (Pimentel, Zuniga & Morrison 2005) introduced to its waterways, mostly in regions that typically have a warm climate. Due to the introduction and subsequent establishment of these species, forty-four different species of fish native to the United States are currently threatened or endangered. A study recently conducted put the economic and ecological costs to the United States from the negative effects of invasive species to be around 137 billion dollars annually (Pimentel et al. 2000). The Chesapeake Bay Watershed, one of Virginia’s and the East Coast’s biggest and most important waterways has been in recent years affected in this way by several invasive species, the most serious species being the blue catfish (Ictalurus furcatus). The blue catfish is marked in both Virginia and Maryland as one of the top five “species of concern” (Higgins 2006) regarding damage potential to the ecosystem and the industries that are supported by it. While blue catfish are native to the Ohio, Mississippi, and Missouri river basins in the south and central area of the United States (Schloesser et al. 2011), they are not indigenous to any waterways of Virginia. Blue catfish were originally introduced to the Chesapeake Bay Watershed in the 1980’s as part of an attempt by the US Fish and Wildlife Service and Virginia Department of Game and Inland Fisheries to improve the sport fishing industry of Virginia and the surrounding areas. These fish were only ever intentionally stocked in the James, Mattaponi, and…
Invasive species in the great lakes consist of Asian carp, Zebra mussels, and, lamprey. Asian carp are native to eastern Africa they also can grow up to 5 feet long and weigh up to 100 pounds! Zebra mussels are native to Ponto Caspian Sea and are only finger nail sized! The lamprey is native to the North Atlantic Ocean and can grow up to 2 feet long! Invasive species can end up somewhere on their own or be put there by someone. The great lakes are filled with all three of these invasive species.…
It is said that CYPRINUS carpio, or as it is more widely known as the European Carp, is one of the world's most common freshwater fish. How the European Carp arrived or when is unclear but the effects are noticeable since the carps have no natural predators in the waters of Australia so they are populating in an extraordinary rate. Which decreases the quantity of prey they have since they are consuming so much, in a small period of time. In the attempt to…
The state of Iowa is a diverse region, providing unique angling opportunities across the state(Iowa Fish Species). Not all the fish are in one area so you have to know what kind of fish you want. If you are looking for Trout you want to head up to the northeast corner of Iowa, almost into Wisconsin. There is primitive trout fishing anywhere in the northeast parts of Iowa. If you are looking for catfish there are many different areas in Iowa to catch them but the most common is the Mississippi River, but many catfish can be found…

CARP Meaning Comprehensive Agrarian Reform Program of 1988, also known as CARP, is a Philippine state policy that ensures and promotes welfare of landless farmers and farm workers, as well as elevation of social justice and equity among rural areas. Agrarian reform is a 100-year history of unfinished reforms after the United States took over the country from the Spaniards. Before the Hispanic period, there were no owner-cultivators, only communal…
“3010 apparently healthy and naturally infected fishes of different species (tilapia sp., catfish, carp sp., mullets and bayad were collected from December 2000 to December 2003 from different fish farms in Sharkia, Damietta and Fayuim. These fishes were subjected to full clinical, parasitological and histopathological examinations. The infested fishes suffered mainly from respiratory manifestations, blackness of the skin and mortalities. The parasitic infestations were found to be the major problem and the most prevalent disease causative agents among cultured fish spp. Their percentages were 54.5 % (918 infected fish out of 1686), 62.2 % (585 infected out of 941), 44.4 % (51 infected out of 115), 22.2 % (6 infected out of 27), 15.7 % (17 infected out of 108) and 10.5 % (14 infected out of 133) in adult tilapias, frys & fingerlings of tilapias, catfish, Bagrus bayad, mullets and carp sp. respectively. The isolated parasites were Trichodina, Monogenea, Henneguya sp., EMC of Centrocestus, Clinostomum and Prohemistomum sp. The prevalence of those parasites among different cultured fishes in Sharkia, Damietta and Fayium was studied. The histopathological alterations due to different parasitic agents were mainly hyperplasia and even complete sloughing of secondary gill lamellae, multiple EMC surrounded…
