Later it was used in the field of tourism planning with J. Alan Hagar in his publication in 1964 entitled The Carrying Capacity of Wild Lands for Recreation where it defines the level of use that an area can support without affecting its quality, applied in the management of visitors in parks and reserves. Fishing has become an important recreational activity for people around the world, contributing to the economies of several countries, generating billions of dollars. In Brazil the expansion of amateur fishing occurred in the 1990s, initially in the Pantanal and today throughout the country. In the Amazon they occur in the rivers of black water, in Roraima on the ??gua Boa do Univini river, due to the presence of large tucunar??s (Cichla spp.). Considering that the establishment of a maximum limit of sport fishermen is an element that can help in the management of fishing, the present study applied the method developed by Cifuentes et al. (1992) adapted to the aquatic environment, to estimate the load capacity of the sport fishing practiced on the ??gua Boa River of Univini, the influence of conservation units as a source of replacement for the stocks of tucunar??s and the profile of practicing tourists in the area of study. For that, experiments were carried out during the period of the sport fishing season of the state of Roraima between October 2018 and March 2019 on the ??gua Boa do Univini river, a tributary of the right bank of the Branco river, in the two projects located in the river. For the determination of the physical load capacity was found the result of 45 motorized fishing boats used in the river simultaneously by the two enterprises. The actual and effective cargo capacities obtained the same levels of physical cargo capacity, which were 12 boats simultaneously fishing in the river. When comparing the suggested limits with the current rates of sport fishermen, it is verified that the load capacity is within the acceptable for the practice of sport fishing in the ??gua Boa do Univini river. Influence of UC on fish caught in fishing grounds. The tucunar?? a??u had an average size of 53 to 85 cm, the paca 35 to 62 cm, the taua with 10 to 35 cm and the butterfly with 30 to 40 cm. In relation to the weight of the four species, A??u average weight of 3.5 to 6.5 kg, paca 2.0 to 5.0 kg, tau?? 0.4 to 1.8 kg and butterfly 1.0 to 1.8 kg. The number of fish, 4 fish captured, large paca 25 medium to large, tau?? 10 fish and butterfly in larger quantity with 78 fish. A questionnaire was applied to national and foreign sport fishermen and fishing guides as an exploratory research instrument with a quantitative and qualitative approach, the results show a range of age ranging from 30 to 90 years, being 80% male and 20% female, 85% are married and 70% have a college degree, have an income of more than 10 minimum salaries and work in various professions, fish monthly and every six months. The fishing guides have a wide experience in the function, ranging from 10 to 22 years of work in the area. The identification of the great potential of sports fishing tourism should be verified, provided that measures are taken of zoning strategies of fishing areas and definition of cargoes of exploitation by the embedded sport fishing. O conceito de capacidade de carga surge nas ??reas da Ecologia, no manejo das pastagens, na d??cada de 1930 nos Estados Unidos da Am??rica, como uso recreativo. Posteriormente passou a ser utilizada no campo do planejamento tur??stico com J. Alan Hagar, em sua publica????o em 1964, intitulada The Carrying Capacity of Wild Lands for Recreation, onde define o n??vel de uso que uma ??rea pode suportar sem afetar a sua qualidade, aplicado no manejo de visitantes em parques e reservas. A pesca tornou-se uma importante atividade recreativa para pessoas em todo o mundo, contribui para as economias de diversos pa??ses, gerando bilh??es de d??lares. No Brasil a expans??o da pesca amadora ocorreu na d??cada de 1990, inicialmente no Pantanal e hoje em todo o pa??s. Na Amaz??nia ocorrem nos rios de ??gua preta, em Roraima, no Rio ??gua Boa do Univini, devido ?? presen??a de grandes tucunar??s (Cichla spp.). Considerando que o estabelecimento de um limite m??ximo de pescadores esportivos ?? um elemento que pode auxiliar no ordenamento da pesca, o presente estudo aplicou o m??todo desenvolvido por Cifuentes et al. (1992) adaptada para o ambiente aqu??tico, para estimar a capacidade de carga da pesca esportiva praticada embarcada no Rio ??gua Boa do Univini, a influ??ncia das unidades de conserva????o como fonte de reposi????o para os estoques de tucunar??s e o perfil dos turistas praticantes na ??rea de estudo. Para tanto, foram realizados experimentos no per??odo da temporada de pesca esportiva do Estado de Roraima, compreendida entre outubro de 2018 a mar??o de 2019 no Rio ??gua Boa do Univini, afluente da margem direita do Rio Branco, nos dois empreendimentos situados no referido rio. Para determina????o da capacidade de carga f??sica foi encontrado o resultado de 45 barcos motorizados de pesca utilizados no rio simultaneamente pelos dois empreendimentos. As capacidades de carga real e efetiva obtiveram os mesmos n??veis da capacidade de carga f??sica, que foram de 12 barcos pescando simultaneamente no rio. Quando se comparam os limites sugeridos com as taxas atuais de pescadores esportivos, verifica-se que a capacidade de carga est?? dentro do aceit??vel para a pr??tica da pesca esportiva no Rio ??gua Boa do Univini. Influ??ncia da UC nos peixes capturados nas zonas de pesca. O tucunar?? a??u apresentou tamanho m??dio de 53 a 85cm, j?? o paca, 35 a 62 cm; o tau??, com 10 a 35 cm, e o borboleta, com 30 a 40 cm. Em rela????o ao peso das quatro esp??cies, A??u peso m??dio de 3,5 a 6,5 kg; paca, 2,0 a 5,0 kg; tau??, 0,4 a 1,8 kg e borboleta 1,0 a 1,8 kg. O n??mero de peixes a??u capturados foi 4 peixes grandes; paca, 25 m??dios a grande; tau??, 10 peixes, e borboleta, em maior quantidade, com 78 peixes. Aplicou-se question??rio aos pescadores esportivos nacionais e estrangeiros e guias de pesca como instrumento de pesquisa explorat??ria, com abordagem quantitativa e qualitativa. Os resultados mostram uma amplitude de idade variando de 30 a 90 anos, sendo 80% do sexo masculino e 20% do feminino; 85% s??o casados, e 70% t??m curso superior. Apresentam uma renda superior a 10 sal??rios m??nimos e exercem profiss??es diversas, pescam mensalmente e semestralmente. Os guias de pesca apresentam uma larga experi??ncia na fun????o, variando de 10 a 22 anos de trabalho na ??rea. Constata-se a identifica????o de ??timo potencial do turismo de pesca esportiva, desde que sejam tomadas medidas de estrat??gias de zoneamento de ??reas de pesca e defini????o de cargas de explora????o pela pesca esportiva embarcada. Um pouco, devido a habilidade com o computador. Bastante did??tico o programa, de f??cil compreens??o. |
