[19], Due to the high density of water, sound travels 4.8 times faster and over longer distances under water than in air. [17] This chemical change in the amino-acid composition of the skin mucus can be noted by chromatographic methods, and are not long-lasting; rather, they last only long enough to communicate to other fish in the vicinity. 45.23 Here are the largest channel catfish ever recorded from every state in America: … Whaley from Santee-Cooper Reservoir, South Carolina in July of 1964. [17], Territoriality in channel catfish is identifiable by a change in body odor, which is recognizable by other members of the same species. Furthermore, the average size channel catfish an angler could expect to find in most waterways would be between 2 and 4 pounds. [17], In the channel catfish, while a communication signal is directed toward the receiver and contains a specific message, an information signal is a part of the general existence of the individual or the group. In addition to communication towards predators, stridulation can be seen as a possible alarm signal to other catfish, in the sense of warning nearby individuals that a predator is near. The relationship between length (L, in cm) and weight (W, in kg) for nearly all species of fish can be expressed by an equation of the form: Invariably, b is close to 3.0 for all species, Typical bait for these traps include rotten cheese and dog food, or "stink bait", and old rotted shad work well. The current World Record Channel Catfish, as recognized by the International Game Fish Association, is a 58 Lb. Catches of as many as 100 fish a day are common in catfish traps. A member of the American catfish genus Ictalurus, channel catfish have a top-end size of about 40–50 pounds (18–23 kg). Another method uses traps, either "slat traps" — long wooden traps with an angled entrance — and wire hoop traps. These buds are especially concentrated on the fish's four pair of barbels (whiskers) surrounding the mouth — about 25 buds per square millimeter. The Channel Catfish is one of America’s most popular gamefish. [24] The volume of the swim bladder changes if fish move vertically, thus is also considered to be the site of pressure sensitivity. Ken Paulie holding his world-record flathead catfish ©Photo from Jocelyn Harris. Catfish have even been known to take Ivory soap as bait and even raw steak.[27]. In addition, the channel catfish has taste buds distributed over the surface of its entire body. = His monster fish catch weighed in at an amazing 123 pounds and was slightly longer than five feet long. Variation in the contents of the club cells’ information signals therefore may change with the species’ needs at different stages of life. The most widespread of all North American catfish species, the world record channel catfish is in many ways the most surprising of all. No votes so far! [22] The first ray of the channel catfish pectoral fin is a bilaterally symmetrical spinous structure that is minimally important for movement; however, it can be locked as a defensive adaptation or used as a means for sound production. At the pits of their nostrils (nares) are very sensitive odor-sensing organs with a very high concentration of olfactory receptors. The popularity of channel catfish for food has contributed to the rapid expansion of aquaculture of this species in the United States. The catfish has a facial taste system that is extremely responsive to L-alanine and L-arginine. [20], The inferior division of the inner ear, most prominently the utricle, is considered the primary area of hearing in most fishes.

This is reported to cause maxillary and mandibular barbell movements, which orient the catfish's posture and food search. The channel catfish (Ictalurus punctatus) is North America's most numerous catfish species. {\displaystyle L_{1}=45.23} in channel catfish have focused primarily on inbred lines and farm strains of relevance to the aquaculture of this species. [2][3] It has also been widely introduced in Europe, Asia and South America, and it is legally considered an invasive species in many countries.[4][5][6]. [25], Channel catfish are omnivores, and can be caught using a variety of natural and prepared baits, including crickets, nightcrawlers, minnows, shad, freshwater drum, crawfish, frogs, bullheads, sunfish, chicken liver, hot dogs, and suckers. L When removing the hook from a catfish, anglers should be mindful of the sharp spines on the pectoral and dorsal fins. [17] Members of the genus Ictalurus, which inhabit muddy waters, do not depend solely on visual cues. The channel catfish reference genome sequence was generated alongside genomic sequence data for other scaled and unscaled fish species (other catfishes, the common pleco and southern striped Raphael; also common carp), in order to provide genomic resources and aid understanding of the evolutionary loss of scales in catfishes. More specifically, their facial taste system senses heightened levels of L-amino acids in freshwater. The relationship between length and weight is not linear. Channel catfish possess very keen senses of smell and taste. [22] According to one scholar, most fish tend to produce sound with their right fin, although sound production with the left fin has also been observed. Jon B Unboxes The MOTHERLODE Bass Fishing Crate! [18] Variability in the sound signals created by the channel catfish depends on the mechanism by which the sound is produced, the function of the resultant sound, and physical factors such as sex, age, and temperature. [17], All species of catfishes can generate sound through stridulation, and many produce sounds through drumming. This massive flathead catfish was estimated to be a little over twenty years old when it … [17] Changes may be the result of the release of the contents of the club cells. 1 [21], In many channel catfish, individuals favor one fin or another for stridulatory sound production (in the same way as humans are right-handed or left-handed). Specifically, they have high sensitivity to amino acids, which explains their unique communication methods as follows. [21] Sudden, relatively loud sounds are used to startle predators in a manner analogous to the well-documented, visual flash display of various lepidopterans. All-Tackle Record:26.3 kilograms (58 pounds), Santee-Cooper Reservoir, S.C., USA. Feeding behavior to food is due to amino acids released by food. Channel catfish swim in ponds, rivers, lakes, and creeks making them accessible to anglers across the country.Channel catfish are known for their strong sense of smell, spunky attitude, and delicious flavor. [20] Different sounds may be used for different functions in communication, such as in behavior towards predators and in asserting dominance. Ken Paulie currently holds the record for catching the largest flathead catfish, and he has held that record for approximately twenty years. [18] The pectoral spine of the channel catfish is an enlarged fin ray with a slightly modified base that forms a complex articulation with several bones of the pectoral girdle. [citation needed] In channel catfish, these organs are sensitive enough to detect several amino acids at about one part per 100 million in water. [29] Other studies of genetic diversity, outcrossing, etc. [18], The North American channel catfish is an ostariophysan, or a bony fish occupying a freshwater habitat. cm. Both the fish's habitat and the presence of chemosensory cells covering the body are presumably the results of favored selection for this method of communication. {\displaystyle L_{1}} [citation needed] They also possess a Weberian apparatus, which amplifies sound waves that would otherwise not be perceivable.[9]. The world record channel catfish weighed 58 pounds, and was taken from the Santee-Cooper Reservoir in South Carolina, on July 7, 1964.
