Use of fishing resources by women in the Mamanguape River Estuary, Paraíba state, Brazil

Abstract

We evaluated the appropriation and use of fishing resources by women residing near the Mamanguape River Estuary (MRE), Paraíba state, Brazil. Were used combinations of qualitative (interviews and direct observations) and quantitative methods (use value and corrected principal use concordance). Thirty women were interviewed and reported the use of 41 species (30 fish, 8 crustaceans, and 3 mollusks), mainly for local consumption and sale. The species with the highest use value were Genidens genidens (0.7), Callinectes exasperatus (0.73) and Anomalocardia brasiliana (0.46). The diversity of resources exploited demonstrates the importance of the mangrove ecosystem to MRE families, and the data gathered can serve as a basis for formulating public policies to promote the equal participation of women in fishing and environmental conservation.

Gender and small-scale fisheries in Brazil: insights for a sustainable development agenda

“…Moreover, when performing their role, they do it differently from men: women tend to fish in different areas than men and target other species. Disregarding the role of women in fishery management implies leaving out of management discussions many relevant species and environments that support extensive marine and terrestrial food webs, such as mangroves (Rocha et al, 2012;Kleiber et al, 2015). Their proximity and daily observation of such ecosystems unveil information that fisherfolks from other areas are unaware of (Santos, 2015).…”

Carbon primary sources and estuarine habitat use by two congeneric ariid catfishes in a subtropical coastal lagoon

“…Earlier work conducted in the 1980's at Patos Lagoon documented that the catfish G. genidens is an estuarine resident (i.e., completes its entire life cycle within the estuary) and the marine catfish G. barbus is an anadromous species (i.e., adults migrate from marine areas to breed in the freshwater reaches of this lagoon) (chao et al 1985(chao et al , reiS 1986(chao et al , araúJo 1988. Previous studies in other estuaries of the Atlantic Southwest (Mazzoni et al 2000, DenaDai et al 2012, rocha et al 2012 have also claimed that ariid catfishes use the estuarine zone for reproduction, development and/or for feeding. However, we do not know of any prior studies using natural tracers to investigate how ariid catfish species use estuarine and freshwater habitats in southwestern Atlantic estuaries.…”

“…Fish moving in and out of estuaries into adjacent areas can mediate this nutrient flux between ecosystems (nelSon et al 2012, JarDine et al 2012, generating carbon subsidies among food webs of marine, estuarine and freshwater regions (Mcavoy et al 2000, garcia et al 2007, KoShino et al 2013). Examples of fish using estuaries during part of their life cycle (e.g., as juveniles) and then moving into adjacent marine or freshwater areas are commonly found among catfishes (chao et al 1985, araúJo 1988, goMeS & araúJo 2004, rocha et al 2012. At Patos Lagoon (32°S), for instance, young-of-the-year Genidens barbus (Lacepède, 1803) born in summer move from the northern limit of the estuarine zone (close to the freshwater portion of the lagoon) to the southern reaches of the estuary (near its connection with the sea) in autumn and winter, and return back to the freshwater region in the following spring and summer.…”

A closer look at the Impact Factor (JCR 2012): problems, concerns and actions needed

“…The AABC is the sole multidisciplinary journal produced in Brazil, publishing mainly original research in distinct areas such as Mathematical Sciences (e.g., Kwakkel et al 2011), Paleontology (e.g., Jiang andWang 2011), Biomedical Studies (e.g., Cruz et al 2012), Agriculture (e.g., Monteiro et al 2012), Social Sciences (e.g., Rocha et al 2012) The present case raises the question if such incidents are rare or if they occur more regularly with volumes/ issues from other periodicals as well. If similar "missing issues" or "late issue additions" regarding this prestigious database are more common and not corrected, than the credibility of the system is at stake.…”
