The species is also known to enter brackish waters, with some individuals known to penetrate far upstream; however, like most euryhaline species, they generally do not penetrate very far upriver. [17] The water salinities where the species has been reported from range from 0% to 49%, indicating the species can adapt to a wide range of waters. [18]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups. Ambiguous common names are accompanied by their possible meanings. Scientific names for individual species and higher taxa are included in parentheses.
An average adult channel catfish measures at least 12 inches (30 centimeters) long, and weighs between 2 and 4 pounds. The largest specimen on record weighed 58 pounds and was caught in 1964 by an angler in South Carolina. [16] As channel catfish grow longer, their weight increases. The relationship between length and weight is not linear.
This species, which can range up to 0.45 m (1.5 ft) in length and weigh 1.5 kg (3.3 lb), is sometimes commercially fished. [77] [92] Characins (Characiformes) The largest species is the African freshwater fish, the giant tigerfish (Hydrocynus goliath). The top size of this fish is 1.5 m (4.9 ft) and 50 kg (110 lb).
In stained water, this fish's background may take on a golden hue. Its shape and coloration is reminiscent of a brown trout. This fish is closely related to the weakfish, Cynoscion regalis. [citation needed] The average size of spotted seatrout is 0.5–1.0 kg (1.1–2.2 lb), but in most areas fish up to 2.5 kg (5.5 lb) are fairly common.

All species of tuna are reported to spawn in water temperatures above 24 °C (75 °F). [29] However, 24 °C (75 °F) is outside, or at the upper limit, of temperature tolerances for bluefin tunas. Large individuals have been found to withstand temperatures of less than 10 °C (50 °F) and as low as 7 °C (45 °F) for over 10 hours, possibly to ...
Swordfish prefer water temperatures between 18 and 22 °C (64 and 72 °F), [3] but have the widest tolerance among billfish, and can be found from 5 to 27 °C (41 to 81 °F). [6] This highly migratory species typically moves towards colder regions to feed during the summer. [6]
