Desta forma, este trabalho teve o objetivo de investigar as quantidades pescadas e os valores gerados por diferentes modalidades de pesca de ?gua doce no mundo e testar a hip?tese de que a contribui??o econ?mica da pesca continental de pequena escala ? maior em pa?ses em desenvolvimento do que das outras modalidades de pesca de ?gua doce em pa?ses desenvolvidos. Para tanto, foi feita uma revis?o sistem?tica da literatura e s?ntese de informa??es. Assim, p?de-se observar que no per?odo de 2004 a 2015, a produ??o de pesca de ?gua doce acumulou perda de 775 milh?es de toneladas. A produ??o da pesca de ?gua doce diminuiu acentuadamente a partir de 2010. A pesca de subsist?ncia foi registrada principalmente em ?frica e a pesca em pequena escala prevaleceu na ?sia. A maior produ??o de pesca foi registrada nos EUA (principalmente recreativa) e no Mali, na ?frica Ocidental. O desenvolvimento da pesca de ?gua doce ainda ? encorajado nessas ?reas onde corpos d??gua est?o mal gerenciados, mas os dados aqui reunidos sugeriram o contr?rio; os ambientes de ?gua doce devem ser monitorados e conservados com o objetivo de conduzir um melhor gerenciamento, uma vez que globalmente a pesca tem sido intensamente praticada nessas ?reas. / The benefits of small-scale freshwater fisheries In addition to consumption for food security, they make an important contribution to an economy both locally and regionally, as well as on an international scale, in this way, with the objective of investigating how the Quantities, hake and the values generated by different modes of freshwater fishing in the world and test a hypothesis of an economic contribution of small-scale continental fisheries is higher in developing countries than other forms of freshwater fishing in developed countries. For this, a systematic review of the literature and synthesis of information was made. Thus, it could be observed that in the period 2004-2015 the freshwater fisheries production, accumulated a loss of 775 millions of ton. Freshwater fishery production abruptly decreased markedly from 2010 onwards. Subsistence fishery was chiefly recorded in Africa and the small-scale fishery was prevalent in Asia. The highest fishing production was recorded in USA (mostly recreational) and in Mali, in western Africa. The development of FWF is still encouraged in those areas were inland water bodies are under-utilized and poor managed, but data gathered here suggested otherwise; freshwater environments should be indeed monitored and conserved aiming management since fishery has been intensively performed in these areas through the world.
