Forage fish angled for trout and salmon which they called "game fish". Fish other than game fish were disdained as "coarse fish". These days, "game fish" refers to Salmonids (other than grayling) — that is, salmon, trout and char. Coarse fish are made up mostly of the larger species of Cyprinids (carp, roach, bream) as well as pike, catfish, gar and lamprey. Coarse fish are no longer disdained; indeed, fishing for coarse fish has become a popular pastime. Forage fish are sometimes referred to as "bait fish" or "feeder fish". Bait fish is a term used particularly by recreational fishermen, although commercial
Environmental impact of fishing relation to their locations and mating and migration cycles. While catch-and-release fishing has been wildly used in recreational fishing, it is also beneficial for maintaining fish populations at a stable level for commercial fisheries to receive social and economic benefits. Combining catch-and-release fishing with biotelemetry data collection methods allows for researchers to study the biological effects of catch-and-release fishing on fish in order to better suit future conservation efforts and remedies. The environmental impact of recreational fishing may be alleviated to some extent by catch and release fishing.
