Dr. Arthur Kanev travels extensively, having visited more than 87 countries so far. On these treks, it would not be unheard of for Dr. Kanev to study the skills of artisanal fishers who generally use traditional methods of fishing for survival. Cultural heritage also leads some artisanal fishers to hold to their ancient methods. Commercial fishers generally use different types of net techniques, while recreational fishers prefer angling, which requires some art and skill.
Dr. Arthur Kanev, who fishes for relaxation, is interested in the habits of fish, their migrations, foraging preferences and habitat. A combination of traditional knowledge and folklores often add to the enjoyment of recreational fishing. Experienced fishermen become quite knowledgeable about the tackle used including hooks, lines, sinkers, floats, rods, reels, baits, lures, spears, nets, gaffs, traps, waders and tackle boxes.
Dr. Arthur Kanev is well-versed in the many conventions, rules, laws and licensing parameters of fishing for recreation and for sport, most of which revolve around the way in which fish may be caught. In most recreational fishing, or angling, it is expected that the fish be returned to the water. Some venues allow fishing only on the caveat of catch and release. Much of sport fishing resolves around the challenge of catching deep water species, not on the value of the fish for consumption. Fish hatcheries grow juvenile fish for release into the wild to supplement the natural numbers of a species, supporting the sport fishing industry with species such as salmon, carp, tilapia, catfish and trout.
