There is an intricate link between various fishing techniques and knowledge about the fish and their behaviour including migration, foraging and habitat. The effective use of fishing techniques often depends on this additional knowledge. [1] Which techniques are appropriate is dictated mainly by the target species and by its habitat. [2]
Fisheries science is the academic discipline of managing and understanding fisheries. [1] It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, meteorology, conservation, ecology, population dynamics, economics, statistics, decision analysis, management, and many others in an attempt to provide an integrated picture of ...
Fishing tools from the Mesolithic and Neolithic period. Fishing is an ancient practice that dates back to at least the beginning of the Upper Paleolithic period about 40,000 years ago. [4] Isotopic analysis of the remains of Tianyuan man, a 40,000-year-old modern human from eastern Asia, has shown that he regularly consumed freshwater fish.

Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life [1] or, more commonly, the site where such enterprise takes place (a.k.a., fishing grounds). [2] Commercial fisheries include wild fisheries and fish farms , both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%).
It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is called industrial fishing. The major fishing industries are not only owned by major corporations but by small families as well. [7]
Artisan fishing uses traditional fishing techniques such as rod and tackle, fishing arrows and harpoons, cast nets, and small (if any) traditional fishing boats. For that reason, socio-economic status of artisanal fishing community has become an interest of the authorities in recent years.
Economics became more mathematical as a discipline throughout the first half of the 20th century, but introduction of new and generalized techniques in the period around the Second World War, as in game theory, would greatly broaden the use of mathematical formulations in economics. [8] [7]
