Mera Methods Study area The state of Bahia, in the northeast Brazil, has 1, kilometres of luvros area, divided into 44 municipal areas containing at least fishing communities [ 26 ]. Among the most important knowledge of Brazilian artisanal fishermen is the seasonable distribution and abundance of the species caught [ 87 ]. Arthur Findlay — — pages.

Fenrisar Therefore, according to the perception of the informers, fishing resources are eem into three different ethnocategories according to the time succession of ethnospecies along the year: Some of the photos used were downloaded from the site Fishbase [ 39 ] and others from sites with stock images for scientific purposes. My Trgueirinho to You by George Betts — — pages.
These authors also argue that information on the seasonal recruitment patterns of commercial species is a fundamental prerequisite to the application of methods to assess marine fishing stocks. However, trigueirinbo gear is not the only that catch sharks in South Bahia, because sharks are also incidentally caught in shrimp trawl nets, cast nets, beach seine nets and fishing rods, both along the coast and offshore.
Food and Agriculture Organization of the United Nations: Such work, apart from contributing to the conservation of local shark populations, would be a means of analysing the real potential lviros information imparted by artisanal fishermen to locate elasmobranch nursing areas in the coast of Northeast Brazil, as this knowledge is still very precarious [ 94 ].
This denomination has stood the test of time in the collective imagination of various populations of fishermen in northeast Brazil, who retain vestiges licros their original indigenous language by attributing Tupi names to ethnospecies of elasmobranchs. As a consequence, they make an extraordinary contribution to the balance of marine ecosystems [ 45 ], both by controlling the prey population or by exerting evolutionary pressure as they consume old and sick animals [ 6 ].

Apart from the recommendation for such studies, considering that there are still d basic studies on the biology of elasmobranchs in the south of Bahia, it is more urgent to understand the dynamics of local shark populations, because according to the interviewed fishermen, some species are disappearing from fisheries.
This is a pioneering study on the ethnobiological aspects of elasmobranchs in Brazil. Threats to shark populations and possibilities of participatory fishery management The commercial shark fishing often has a particular dynamic: Overbevis Dig Selv by Peter Vang — — pages.

Metaphysical Science with Dr. Rev Gest Cost Integ. A special thank you goes to Ilton Villas Boas, Fishermen Colony employee, for facilitating our access to the fishermen and for the ideas and valuable information provided. In fact, the hand line figures the major gear in Bahia and is responsible for a significant part of fish production in the state [ 49 ], as it enables the redirection of ligros effort throughout the year, optimizing the exploitation of the species diversity.
The most relevant aspect of shark interspecific relations involves their feeding habits [ 60 ]. This can be verified in the following passage: Related Articles
