Ethnoecology and socioeconomic around an artificial reef: the case of artisanal fisheries from southeastern Brazil

Abstract

The objective of this study is to describe the ethnoecological aspects, valorization, and commercialization of target species caught by artisanal fishers on the northern coast of Rio de Janeiro, southeastern Brazil. The data were obtained through semi-structured interviews conducted with 60 fishers from the fishing community of Guaxindiba (21°29'S, 41°00'W), which is associated with the Z-1 fishers' colony. Eighty-nine species were cited by the fishers and 44.1% are important commercial fish in the region. The fishers cited five distinct zones used to fish: border zone (68 species), estuary (41 spp.), artificial reef (27 spp.), "malacacheta" (24 spp.), and open ocean (10 spp.). The fishery resources were classified according to their gastronomic and economic characteristics: primary fish (35 spp.), secondary fish (32 spp.), mixed fish (10 spp.), discarded fish (7 spp.), and fish used as bait (5 spp.). The price of the target species increases along the production chain due to the greater number of people involved, processing costs, and improvement of the product. The data from this study can contribute to local fisheries management and point out to the use of artificial reefs in the maintenance of fishery resources in northern Rio de Janeiro.

Marine artificial reef (MAR) interference in artisanal fisheries in Brazil: use of traditional knowledge

“…Artisanal fishermen have deep local knowledge of the environment acquired during fishery operations (Murray et al, 2006;Musiello-Fernandes et al, 2020). Artisanal fisheries represent an economic activity exercised by fishermen who can perform alone or in partnerships, in which fish are caught using relatively simple gear and less intensive and aggressive technologies (Batiste, et al, 2014;Lima et al, 2019). The production from artisanal fisheries (i.e., the fish captured and traded and used for subsistence) is relatively low.…”

“…Their surfaces provide suitable environments for the proliferation and increase of fishery biomass through the development of flora and fauna from reef environments; therefore, they are used for biodiversity maintenance (Seaman, 2000;Vivier et al, 2021). MARs work as substrates and shelters for several marine communities with ecological and economic significance, creating alternatives for artisanal fishery activities (Bohnsack and Sutherland, 1985;Lima et al, 2019;Vivier et al, 2021).…”

Conhecimento Ictioparasitológico Tradicional Dos Pescadores Artesanais Do Rio Jaguaripe, Bahia, Nordeste Do Brasil

“…Estudos do CEL em comunidades de pescadores encontram-se bem desenvolvidos no Brasil, com várias pesquisas nas diferentes regiões (ARRUDA et al, 2018;BARROS, 2012;CARVALHO, 2002;GÜLLICH, 2019;HAVERROTH, 2018;LIMA et al, 2019;MESSIAS et al, 2006;MOURA e MARQUES, 2006;NUNES et al, 2011a;PIEVE et al, 2005;SILVANO e BEGOSSI, 2012). Estudos como os de Begossi et al (2011de Begossi et al ( e 2012 e Costa-Neto et al (2019) têm um caráter aplicado referente ao CET, à media que propõem uma abordagem da gestão da pesca artesanal com a participação de pescadores, apontando sugestões para o manejo e criação de estratégias de proteção aos recursos naturais aquáticos.…”

Integrative taxonomy identifies a new stingray species of the genus Hypanus Rafinesque, 1818 (Dasyatidae, Myliobatiformes), from the Tropical Southwestern Atlantic

“…To determine if H. americanus constitutes a broadly distributed species or a species complex, samples, specimens and records of all putative H. americanus , along with the closely related H. longus and H. rudis , were assessed. This information will be useful to evaluate the conservation status and to support fisheries management policies of Atlantic stingrays to be effective (Almeida Marques et al ., 2019; Dulvy et al ., 2017; Lima et al ., 2019).…”
