Help us improve the site by taking our survey. Bacteria including Aeromonas hydrophila, Flavobacterium columnare, and Edwardsiella ictaluri also impact catfish health. In the James River, they can grow up to 3 pounds in the first 8 years, while in 11 years, they can reach 20 pounds. In size, flatheads are the second largest sport fish in Texas after their cousin, the blue catfish. Blue catfish (I. furcatus) brood fish are collected from the wild. In the lower Mississippi River, it moves farther down river where the water is warmest in winter, and it runs upstream in summer. Once eggs are fertilized, male catfish force females away from the nest to organize and protect the eggs. Reproduction begins with the foundation and creation of a nest in a suitable place by a male. Males build nests and attract females using species-specific pheromones before they swim together in various patterns. Their bodies appear bluish-silver and grey dorsally, silvery-white on their sides, and white ventrally. Its tail is high and crescent-shaped. Recognized for their large bodies that can weigh up to 100 pounds (45kg), blue catfish can reach two to five feet in length (600 to 1500mm).

It is no accident that catfish can survive in such adverse conditions. Blue catfish are an excellent food source for avian predators of the Chesapeake region and are also food sources for otters, and predatory fish like flathead catfish. Fry are very small and are easily preyed upon by other fish, so they feed nocturnally at low depths and near cover on zooplankton and aquatic insects. A catfish has a few adaptations to help them see and feed in the darkness of the water. Topics Although blue catfish prefer freshwater, in rare situations they can occur in brackish estuaries with salinities below 12%, and can tolerate salinities up to 22 ppt (parts per thousand). Small channel cats typically will have spots lacking in small blue cats. Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. Their dorsal fin and posterior fins contain spines, which are strongly serrated for defense. Many blue catfish grow to tremendous sizes; this in combination with their feeding style has lead to the belief that they exhibit adverse effects on other fish communities.

Skin coloration can have many functions. Body color varies from steel blue to yellow-brown. Due to the rapid decline of these organisms, blue catfish have gained recognition as a detriment to their own ecosystem. Chesapeake Bay Program. ("Ictalurus furcatus", 2013). They also feed on many other fish, creating pressure and limiting the growth of these species. It is similar to the Channel Catfish, but differs by having a long, straight-edged (vs. shorter, rounded) anal fin and no dark spots on the body.Adults can grow to about 5.5 ft. (150 lbs. 0000002142 00000 n
Blue on the dorsal side (the top) and silvery white on the ventral side (the abdomen), the blue marlin also has more than a dozen rows of blue spots on its body. Smithsonian Environmental Research Center. Usually has a slate blue body with a white belly. Blue catfish can grow to be larger than 100 pounds. at http://www.chesapeakebay.net/fieldguide/critter/blue_catfish. One conspicuous characteristic of all catfish is the presence of barbels around the mouth. Barekzi, Y.; M. Hawkins and J. Texas Parks and Wildlife. Once the young blue catfish hatch, they are believed to form schools before becoming independent. The distribution and further range expansion of non-native blue catfish Ictalurus furcatus in coastal waters throughout the United States Atlantic slope depend, in part, on the salinity tolerance of the fish. Murdy, E., R. Birdsong, J. Musick. There have also been reports of blue catfish in the Burke and Brittle Lakes and far north in the Chesapeake Bay tributaries such as the Susquehanna River. Although the exact habits of blue catfish hatchlings are unknown in the wild, in hatcheries the fry have been observed swimming in schools for several weeks before dispersing; however, this may occur for a shorter time in the wild. Blue catfish were observed to expand their range in Virginia tributaries when adult densities in tidal freshwater reaches were high and in years of high river flows or episodic flooding (Schloesser et al. He also broke numerous water body record breaking six records total. areas with salty water, usually in coastal marshes and estuaries. Mating includes many chemical interactions between males and females. In addition, they seek sturdy and stable surfaces to which their sticky eggs can properly adhere. 0000006157 00000 n
While blue catfish can grow quite large, growth rates can vary considerably from individual to individual and few fish actually reach trophy sizes. Ictalurus is Greek meaning "fish cat", and furcatus is Latin, meaning "forked", a reference to the species' forked tail fin. Grants DRL 0089283, DRL 0628151, DUE 0633095, DRL 0918590, and DUE 1122742. It has a slate blue body, a silver-white belly and four pairs of black, whisker-like barbels around its mouth. 2012. Not only are blue catfish used as sport fishes, they are also an important food source for more than sixteen states. The Animal Diversity Web team is excited to announce ADW Pocket Guides! In Maryland, electrofishing surveys produced blue catfish between the ages of 3 to 14 years; however, the majority were between 5 to 7 years old. 0000009771 00000 n
"Catfish" is the second most preferred group of fish among licensed Texas anglers, and flatheads rank second behind channel catfish. 2013. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Yama Barekzi (author), Bridgewater College, Maria Hawkins (author), Bridgewater College, Jacob Sheets (author), Bridgewater College, Tamara Johnstone-Yellin (editor), Bridgewater College, Leila Siciliano Martina (editor), Animal Diversity Web Staff. living in the Nearctic biogeographic province, the northern part of the New World. Animals. At the same time, the study — which examined 16,110 blue catfish stomachs — cast doubt on the notion that they are voracious, ecosystem-altering predators. Smaller introductions of blue catfish have taken place in the rivers of more than 5 other states such as Alabama, Florida, and California, as well as Mexico. Rounder, flat bellied body. examples of how an organism’s form or body can adapt it for survival. Conf. Mostly, the study found, blue catfish are omnivores, eating whatever is abundant in the river. The NOAA Chesapeake Bay Office (NCBO) and other Chesapeake Bay organizations identified invasive catfish as a challenge facing the Chesapeake ecosystem several years ago. Their color is dark on top so predators in the air don't see them.It is light on it's belly so predators don't see them underwater. 0000004236 00000 n
However, as they age, they become larger than other predatory fish, resulting in less predation. April 20, 2014 makes seasonal movements between breeding and wintering grounds, eats mollusks, members of Phylum Mollusca. One caught in an inland lake on the Virginia–North Carolina border weighed 143 pounds. However, temperature-mediated sublethal effects of increased salinities on blue catfish biology are not yet known. During these times, they seek protected, slightly isolated, and covered areas such as in logs and under rocks. ("Blue catfish - Chesapeake Bay", 2014; Holtan, 1998; "Freshwater catfish in Texas", 2012), Blue catfish have an average life expectancy of 9 to 10 years, but can live to ages upward of twenty years. They use a vigorous sweeping motion with their tails to clear debris and use their jaws to remove larger objects; their nests can range from 6 to 14 inches in diameter. If a catfish is infected by Aeromonas hydrophila, they develop ulcers and their fins redden and begin to fray. In one study, three genetic groups of catfish—NWAC103 line channel catfish, Norris line channel catfish, and a hybrid between the Norris channel catfish and the Dycus Farm line blue catfish—were compared for production, meat yield, and meat quality traits. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. For every kilogram of body weight, females lay 4,000 to 8,000 eggs, a gradual process that may take several hours. The abundance of blue catfish has caused competition with and reduced populations of white catfish in Virginia and Maryland. 1994. "Catfish" (On-line). This species adjusts to water temperature changes and swims to warmer waters during the winter and cooler waters during the summer. During the first few years of development, blue catfish grow slowly; however, this rate typically increases with their size as they age. Adults usually grow to be less than two feet long, but can be as long as five feet and weigh more than 100 pounds.

in press). Edwardsiella ictaluri causes white lesions on their backs and sides to form, and external hemorrhages under their bodies and around their mouths. The Chesapeake Bay record is a blue catfish caught in the James River that was 102 pounds. Males turn blue-gray when they are in breeding condition. This popularity has lead to a profitable business in guided fishing tours. Other. ("Blue catfish - Chesapeake Bay", 2014; Greenlee, 2011; Jenkins and Burkhead, 1994; "Freshwater catfish in Texas", 2012; Wyatt, et al., 2006), Both male and female blue catfish are necessary in order for reproduction to take place. Recognized for their large bodies that can weigh up to 100 pounds (45kg), blue catfish can reach two to five feet in length (600 to 1500mm). Convergent in birds. Guidelines for the culture of blue and channel catfish. Catfish use their sharp fins for fighting. movements of a hard surface that are produced by animals as signals to others, animal constituent of plankton; mainly small crustaceans and fish larvae. The anal fin is long, possesses a straight distal margin, and contains between 27 to 38 rays, although the typical range is 30 to 36. In fact, this unique body structure allows the blobfish to float in the depths of the ocean with very little energy because its flesh is slightly less than water. Blue catfish spawn monogamously, mating with only one partner per yearly reproductive cycle. Specifically, the question was raised as to how catfish can survive in extremely muddy water. April 20, 2014 �Vl�e�K����،��I�ƙ�]��2���D��_��[�?�. Physical characteristics Like all native North American cat-fishes, a channel catfish has a body is located on the back between the dorsal and caudal fins (Fig. Jenkins, R., N. Burkhead. Blue catfish have a more migratory nature than other catfish and often travel long distances in pursuit of these locations. With this physical adaptation, the fish finds food that it can’t see in the darkness at the Hudson’s bottom. Catfish often perform various courtship swimming patterns and even mild biting in the nest before fertilization. H�|T���6��+�(���DQ�-��.Z h�uO�h��ٕE������_v���-6LI�̼y���o7w�%�6M!��N�eѵ�ś�)y

Males remain within the nest after eggs hatch to guard and direct the fry, leaving only when the fry completely absorb their yolk sacs. They are generally warmwater fish that live in ponds, lakes, or quiet, slow moving streams and rivers, but they ar… Hormonal pheromones also play a key role in reproduction and mating systems between blue catfish. The blue catfish is a long fish with a flat dorsal fin and deeply forked tail. Today, their habitat includes most rivers in California, Louisiana, and the Atlantic slope regions including the Rio Grande, James, Rappahannock, Mattaponi, York, Potomac, Patuxent, and Nanticoke Rivers. at http://blueocean.org/documents/2013/03/blue-catfish-chesapeake-bay-full-species-report.pdf. Yaqui chubs can be up to 5H inches (14 cm) long. Once hatched, blue catfish remain in the fry stage until they completely absorb their yolk sacs, a process that is also dependent on water temperature and usually takes between 3 to 6 days. In the James River, blue catfish can grow to large sizes, so recreational fishers often travel to Virginia and the surrounding commonwealths in hopes of catching them. Accessed fertilization takes place outside the female's body. 0000002036 00000 n

Search in feature ("Blue catfish - Chesapeake Bay", 2014; "Blue catfish", 2012; Jenkins and Burkhead, 1994), Blue catfish serve as predators and prey, providing food and selective pressure for the organisms that share their habitat. Accessed January 26, 2021 at https://animaldiversity.org/accounts/Ictalurus_furcatus/. As they grow in size and age, their diet expands to include a variety of smaller fish, even their own species. During spring, they may enter areas with little to no currents such as backwaters, sloughs, and reservoirs for nesting and reproduction. The spines have glands positioned at their base that can expel toxins; they make their way into predators’ wounds and cause sharp pain.

Their general behavior and semantics of reproduction share similarities with the entire Bullhead family, especially with channel catfish. The feeding nature of blue catfish is very opportunistic and can result in cannibalism. These behaviors include biting, slamming into each other, and highly energetic swimming. (Bonvechio, et al., 2012; Jenkins and Burkhead, 1994; Schloesser, et al., 2011; "Ictalurus furcatus", 2014; Wyatt, et al., 2006), Blue catfish populations generate important economic benefits in both recreational and commercial fishing. … 2012.

Fish can also have disruptive markings to hide body parts. These are called . These characteristics include lack of scales, a single dorsal fin followed by an adipose fin just before the caudal fin, and a flat anal fin. Color is another physical adaptation that can help creatures survive. 0000009693 00000 n
Growth rates vary from river to river depending on the population density and available food. However, large channel cats and medium-sized blue cats can be more difficult to tell apart, often having similar coloration and general body shape. Life expectancies can range from river to river, with rivers in Virginia being better suited at producing older and larger catfish. They are neither threatened nor endangered according to the IUCN, United States Federal List, CITES, or the State of Michigan List. Non-indigenous range expansion of the blue catfish (Ictalurus furcatus) in the Satilla River, Georgia. They provide adequate economic success and good sport fishing for many people. that region of the Earth between 23.5 degrees North and 60 degrees North (between the Tropic of Cancer and the Arctic Circle) and between 23.5 degrees South and 60 degrees South (between the Tropic of Capricorn and the Antarctic Circle). (Holtan, 1998; Jenkins and Burkhead, 1994; "Ictalurus furcatus", 2014), Spawning and breeding season occurs once a year, between April and June in freshwater reservoirs and backwaters depending on geographic location.

They often travel upstream during the reproductive seasons and tend to move back downstream towards estuaries after the mating season. Blue catfish account for one third of the total recreational fishing efforts in Virginia, offering a market gain for environmental agencies and fisheries alike. During egg dispersal, male catfish fertilize the eggs with their sperm, which is dispersed in the form of milt upon and near the eggs. Flathead catfish range from the lower Great Lakes through the Mississippi River watershed to the Gulf states. Disclaimer: To help scientists and resource managers learn more about these fish, NCBO provided more than $1 million in funding for research projects to investigate blue catfish. at http://dnr.wi.gov/topic/fishing/documents/species/catfish.pdf.
