The threadfin shad (Dorosoma petenense) is a small pelagic fish common in rivers, large streams, and reservoirs of the Southeastern United States. Like the American gizzard shad, the threadfin shad has an elongated dorsal ray, but unlike the gizzard shad, its mouth is more terminal without a projecting upper jaw. The fins of threadfin shad often have a yellowish color, especially the caudal fin. The back is grey to blue with a dark spot on the shoulder. D. petenense is more often found in moving water, and is rarely found deep in the water column. It occurs in large schools, sometimes with gizzard shad, and can be seen on the surface at dawn and dusk. The threadfin shad may reach lengths of 8 in (200 mm), but only rarely. This fish is very sensitive to changes in temperature and dissolved oxygen, and die-offs are frequent in late summer and fall, especially when water temperature drops to 42°F. The threadfin shad is a favorite food for many game fishes, including striped bass, largemouth bass, smallmouth bass, and catfish. This fish is widely introduced throughout the United States as a forage for game fish.
The threadfin shad is native to the U.S., west of the eastern Appalachian Mountains. This species tends to do best in large lakes and rivers. The construction of dams has created more reservoirs, providing more water bodies for the shad to inhabit. This has expanded the home range of the fish, as has the rise in temperatures in northern lakes.
The adult may reach up to 8 in long, but most shad are about 1 in long. It feeds on plankton near the surface of the water late in the day.It is a very important food source for many game fish such as the largemouth bass. It has little known competition, but one species known to have a similar lifestyle is the gizzard shad (Dorosoma cepedianum). The threadfin lives a pelagic life in reservoirs and for the most part in large streams.
The shad spawns in the spring when the water temperature is in the upper 60s (°F). [ citation needed ] that threadfin shad often compete for plankton with young-of-the-year predator species, especially largemouth bass. Life expectancy seldom exceeds 2 to 3 years.A pelagic (open water) schooling species often introduced as a supplemental forage, threadfin shad spawn in the spring and early summer with a secondary spawn often occurring in the early fall. Spawning usually occurs early in the morning on available vegetation. The eggs adhere to submerged and floating objects. Females lay from 2,000 to 24,000 eggs. The young and adults feed on a variety of planktonic organisms and organic debris. Many researchers believe
Many populations of threadfin shad have been introduced by humans to the far north, resulting in large die-offs in the winter when water temperatures fall below 42°F. This die-off affects both humans and wildlife. A tide of dead fish floats ashore, creating a strong odor unpleasant to humans. The die-off also gives some bird species an unnatural feeding habit, as well. The species should not be transplanted into water bodies that drop below 42°F.This species is not endangered and has relatively healthy populations.
The largemouth bass is a carnivorous freshwater gamefish in the Centrarchidae (sunfish) family, a species of black bass native to the eastern and central United States and northern Mexico, but widely introduced elsewhere. It is known by a variety of regional names, such as the widemouth bass, bigmouth bass, black bass, bucketmouth, largies, Potter's fish, Florida bass, Florida largemouth, green bass, bucketmouth bass, Green trout, gilsdorf bass, Oswego bass, LMB, and southern largemouth and (paradoxically) northern largemouth. The largemouth bass is the state fish of Georgia and Mississippi, and the state freshwater fish of Florida and Alabama.
Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Fish usually migrate to feed or to reproduce, but in other cases the reasons are unclear.
Threadfins are silvery grey perciform fish of the family Polynemidae. Found in tropical to subtropical waters throughout the world, the threadfin family contains eight genera and about 40 species. An unrelated species sometimes known by the name threadfin, Alectis indicus, is properly the Indian threadfish.
The Ocmulgee River is a western tributary of the Altamaha River, approximately 255 mi (410 km) long, in the U.S. state of Georgia. It is the westernmost major tributary of the Altamaha.
The yellow perch, commonly referred to as perch, striped perch or American perch is a freshwater perciform fish native to much of North America. The yellow perch was described in 1814 by Samuel Latham Mitchill from New York. It is closely related, and morphologically similar to the European perch ; and is sometimes considered a subspecies of its European counterpart. Other common names for yellow perch include American perch, coontail, lake perch, raccoon perch, ring-tail perch, ringed perch, and striped perch. Another nickname for the perch is the Dodd fish.
The sauger is a freshwater perciform fish of the family Percidae which resembles its close relative the walleye. They are members of the largest vertebrate order, Perciformes. They are the most migratory percid species in North America. Saugers obtain two dorsal fins, the first is spiny and the posterior dorsal fin is a soft-rayed fin. Their paired fins are in the thoracic position and their caudal fin is truncated which means squared off at the corners, a characteristic of the family Percidae. Another physical characteristic of Saugers are their ctenoid scales which is common in advanced fishes. Saugers have a fusiform body structure, and as a result saugers are well adapted predatory fishes and are capable of swimming into fast currents with minimal drag on their bodies. They may be distinguished from walleyes by the distinctly spotted dorsal fin, by the lack of a white splotch on the caudal fin, by the rough skin over their gill, and by their generally more brassy color, or darker color in some regions. The average sauger in an angler's creel is 300 to 400 g in weight.
Pelagic fish live in the pelagic zone of ocean or lake waters – being neither close to the bottom nor near the shore – in contrast with demersal fish that do live on or near the bottom, and reef fish that are associated with coral reefs.
South Holston Lake is located near the cities of Abingdon, Virginia and Bristol, Virginia / Bristol, Tennessee, and is a 7,580-acre (31 km2) impoundment operated by the Tennessee Valley Authority (TVA). Much of the reservoir is in Tennessee, but the Virginia portion of the reservoir offers anglers more than 1,600 acres (6 km2) of water. At this time there is a South Holston Reservoir Fishing License that will allow anglers from the two states to fish the entire lake with the purchase of this license.
The silver carp is a species of freshwater cyprinid fish, a variety of Asian carp native to China and eastern Siberia. Although a threatened species in its natural habitat, it has long been cultivated in China. By weight more silver carp are produced worldwide in aquaculture than any other species of fish except for the grass carp. Silver carp are usually farmed in polyculture with other Asian carp, or sometimes with catla or other fish species.
Balmorhea Lake is a reservoir on Sandia Creek 2 miles (3 km) southeast of downtown Balmorhea, Texas. Water from Toyah Creek, fed by the nearby San Solomon Springs, is also fed into the reservoir, as is excess water in the Phantom Lake Canal. The reservoir was built in 1917 by the construction of a dam by the Reeves County Water Improvement District. The reservoir provides water for irrigation, and is a popular recreational spot for locals.
Dorosoma is a genus of gizzard shads, fish of the herring family Clupeidae. The five species are native to the North America, and are known from both fresh water and the waters of estuaries and bays.
The American gizzard shad, also known as the mud shad, is a member of the herring family of fish, and is native to large swaths of fresh and brackish waters of the United States of America. The adult has a deep body, with a silvery-green coloration above fading to plain silver below. The gizzard shad commonly resides in freshwater lakes, reservoirs, rivers, and streams, but can reside in brackish waters, as it does on the Atlantic coast of the United States. Their range is across most of the continental United States, although they typically go no further north than New York and no further west than New Mexico. They are large parts of many of the ecosystems they inhabit, and can drive changes in phyto- and zooplankton, thereby indirectly affecting other planktivorous fishes. The gizzard shad has been widely used as a food source for game fish, with varied success in management and effectiveness.
The skipjack shad is a North American, migratory, fresh- and brackish water fish species in the herring family Clupeidae. The name skipjack shad comes from the fact that it is commonly seen leaping out of the water while feeding. Other common names include blue herring, golden shad, river shad, Tennessee tarpon, and McKinley shad. The skipjack shad is restricted to the Gulf of Mexico drainage basins. Skipjack shad are found in clear to moderately turbid water in areas with flow. Because they are a migratory species, dams often impede their reproduction. Records suggest that this species was much more abundant in the Upper Mississippi River basin before it was impounded. Currently, the skipjack shad is most abundant in the Upper Mississippi River below the mouth of the Ohio River. They are known as an "early-run" species as they migrate to spawn in the early spring.
Forage fish, also called prey fish or bait fish, are small pelagic fish which are preyed on by larger predators for food. Predators include other larger fish, seabirds and marine mammals. Typical ocean forage fish feed near the base of the food chain on plankton, often by filter feeding. They include particularly fishes of the family Clupeidae, but also other small fish, including halfbeaks, silversides, smelt such as capelin and goldband fusiliers.
The blueback herring or blueback shad is an anadromous species of herring from the east coast of North America, with a range from Nova Scotia to Florida. Blueback herring form schools and are believed to migrate offshore to overwinter near the bottom.
Canton Lake is a freshwater reservoir located in Fulton County, Illinois. Known for its trophy sized largemouth bass and its abundant channel catfish. The lake's major fish species are Largemouth Bass, Crappie, Bluegill, Yellow bass, Channel catfish, Carp, and Gizzard Shad. The City of Canton, Illinois has various user fees for boat use and an 85 horse power motor limit. The lake had a large number of channel catfish, largemouth bass, and tiger muskie stocked over the last decade.
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton.
