Common carp (Cyprinus carpio)
Part 1:
Introduction: The common carp, Cyprinus carpio is a widespread freshwater fish that belongs to the minnow family “Cyprinidae”. This species is a relatively large species with weights which range from 2-14 kg. The life span of common carp in the wild is up to 20 years. Originally, common carp is native to Europe and Asia and is now the most domesticated and cultivated carp species throughout the world.
Habitats: Common carp can inhabit a wide range of habitats such as lakes, manmade impoundments, but they prefer lower sections of rivers (usually with slow to moderately flowing water), especially those with turbid water.
Water salinity up to about 5‰ is tolerable by common carp. However, based on the occurrence of common carp in in brackish-water estuaries, backwaters, and bays, there are some reports on the common carp living in brackish-water marshes with salinities up to 14 ppt in southern France and on capturing common carp in waters with salinities as high as 17.6 ppt. in USA. Even the best growth of common carp is obtained when water temperature ranges between 23 °C and 30 °C, fish can withstand higher water temperatures and can survive cold winter periods.

Description: Common carp has an elongated and somewhat compressed body with sub-terminal mouth and a long snout, thick lips and two barbels on each side at the corners of the mouth. The species has relatively well-developed, molar-shaped pharyngeal teeth in three rows, with transverse grooves on the rest of the inner row except the first tooth, which is smooth. Their scales cover the entire body. Their color vary with different living environments, usually dark grey or yellowish brown on dorsal; sides, golden yellow; lower part of caudal fin,
The Artemia franciscana can survive in extreme conditions of salinity, water depth, and temperature (Biology 108 laboratory manual, 2010), but do A. franciscana prefer these conditions or do they simply cope with their surroundings? This experiment explored the extent of the A. franciscanas preference towards three major stimuli: light, temperature, and acidity. A. franciscana are able to endure extreme temperature ranges from 6 ̊ C to 40 ̊ C, however since their optimal temperature for breeding is about room temperature it can be inferred that the A. franciscana will prefer this over other temperatures (Al Dhaheri and Drew, 2003). This is much the same in regards to acidity as Artemia franciscana, in general thrive in saline lakes, can survive pH ranges between 7 and 10 with 8 being ideal for cysts(eggs) to hatch (Al Dhaheri and Drew, 2003). Based on this fact alone the tested A. franciscana should show preference to higher pH levels. In nature A. franciscana feed by scraping food, such as algae, of rocks and can be classified as a bottom feeder; with this said, A. franciscana are usually located in shallow waters. In respect to the preference of light intensity, A. franciscana can be hypothesized to respond to light erratically (Fox, 2001; Al Dhaheri and Drew, 2003). Using these predictions, and the results of the experimentation on the A. franciscana and stimuli, we will be able to determine their preference towards light, temperature, and pH.
Distribution – The fathead minnow is a stream fish, able to tolerate a wide range of environmental conditions including high temperatures, low oxygen levels, and high turbidities. The species seems to be most abundant in small streams where competition wi...
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
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).

The normal weight of M. salmoides is one kilogram; however, certain largemouth basses have gotten weights of over ten kilograms. Males usually do not surpass 40 cm, while females can reach up to 56 cm in length. The largemouth bass has a large, slightly sloping mouth. Its body is slender to robust, slightly compressed laterally, and oval in cross section. The corner of the mouth extends past the eye, hence its common name. (Bailey, et al., 2004; Boschung, et al., 2004) Immature Micropterus salmoides feed on zooplankton and marine insects. As they grow their diet shifts to crayfish
Environment: They are usually found in heavy growths of aquatic plants in sluggish streams. They are also found in shallow coves of lakes or in ponds. They prefer water from 75 to 80 degrees. Redfin pickerels may be the dominant predator fish in small creeks. They prefer slow moving, heavily vegetated swamps and millponds.
The type of artificial light and type of fish food given to a fish can also impact the pigmentation and coloration of the fish.
In the first study examined, “Effect of Different Salinities on the Survival and Growth of Artemina Spp,” researchers Soundaraparian and Saravanakumar designed an experiment to ascertain the ideal conditions for the growth of brine shrimp, or Artemina. In the Introduction, the scientists note the growing significance of Artemina, as it is now used as live feed for over 85 percent of cultured species around the world. Thus, a demand to grow huge quantities of Artemia has arisen, making this study incredibly relevant.
The control and management of Asian carp in North America is an issue that numerous state and federal agencies have been trying work out ever since the first case of Asian carp being in the waterways of North America. Asian carp are a very difficult species of fish to manage and control because of their fast reproduction rate and that there are no predators in the North American waterways to reduce numbers. These fish are damaging native fish's food sources and habitat. More recently, Asian carp are threatening to invade the Great Lakes which would cause drastic economic and ecological problems. The fight for control of Asian carp is an ongoing battle and one that needs to be solved before it's to late.
The three most important physical characteristics of the Chesapeake Bay are salinity, temperature, and circulation. Salinity is the measure of the amount of dissolved salts in the water and matters because certain types of fish and bay grasses need a certain amount of salt in the water (“Physical Description”). In general, the lower parts of the Chesapeake Bay are salty and the upper bay is mostly fresh, which means that the fish that need salt like to stay in the lower part of the bay. The fish that cannot survive in salt water will stay in the upper bay (Chesapeake Bay Program”).
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.
... any environment but in the deep sea the fish have had to evolve immensely just to survive.
Ichthyologists say that there are more than 32,000 species of fishes discovered on Earth so far which is more than all the amphibians, reptiles, birds, and mammals combined. Still, new species are being discovered almost every day. Large areas beneath the ocean surface still remain unexplored. It is predicted that there might be more species of fish which are hidden from the eyes of humans till now. All fish differ in sizes. A fish can be as big as a 51 ft long Whale/Shark or as small as an 8mm Stout infant fish. Common type of fish include; gold-fish, Drum, Spadefish, Trout, Skate, Thalla, Tuna, Hogfish, Wahoo, Grunt, Monkfish, Roughy etc. Some organisms which are considered to be a fish actually do not fall into the category of fish. Examples include; shellfish, cuttlefish, starfish, crayfish and jellyfish.
The Michigan Aquaculture Association (MAA) represents producers of fish and seafood that are grown in a safe and environmentally delicate manner. The MAA supports and promotes a well-developed and sustainable aquaculture industry in the State of Michigan, through building partnerships between the industry, universities, public agencies, and consumers (Michigan Aquaculture Association, 2009). Current Michigan aquaculture activities focus on raising fish for use as bait, stocking ponds, fee fishing, and food. The major focus used to be on producing sport fish for stocking and fishing pursuits, changing population demographics and greater consumer interest in healthy diets point to future growth in producing fish for human consumption (Michigan Aquaculture Association, 2009).
