“…Interestingly, some fishing communities have a food aversion to this type of fish (Hanazaki and Begossi 2006;Silva 2006), often explaining this aversion because of the large amount of bones, which increases the preparation time. In this study, the aversion for sardines (12%) was explained due to the small size of these fish, the strong taste, and a lot of bones and a small amount of meat, increasing the manipulation time (see also Begossi et al 2012). By the other hand the preference for sardines for some interviewees may be due to the high availability of the product from the fishing industry, and low commercial value (Sunye 2006).…”

The study of dietary consumption is important to understanding the relationship between eating habits and natural resources, which may reflect adjustments and adaptations demanded by local environmental changes. This study aimed to understand the trophic relationships between the local families' diets and the ichthyofauna present in an urban neighborhood of artisanal fishers in southern Brazil (Tijucas, Santa Catarina). Data were collected through semi-structured interviews in 88 households who reported the consumption of 62 types of fish, where the most consumed were the mullet (Mugil spp.) and croaker (Micropogonias furnieri). Fish is still an important source of animal protein for local families. Preferences and aversions observed can be explained by the relationship between environmental factors and cultural aspects that relate to the economic and social context of the community. In the last decade fish consumption was affected by local immigration and by contextual changes affecting local fisheries.

“…Identifications followed publications about Brazilian coastal fishes used by fishers [8,14,15,57,65] and the experience of some of the authors (AB and RAMS). The few non-identified fishing resources (n ¼8) were excluded from analyses, as these were cited by only one interviewee (0.3% of total) and are possible unusual catches, peculiar names or mistakes.…”

“…The development of this fish includes an inshore larval stage, with juveniles colonizing estuarine environments, including mangroves, drainage areas, sea grass beds and shallow waters (Taylor et al 2000). Interviews with local fishermen indicate that this fish spawns in summer and spring (Begossi et al 2012a). Its capture is associated with migratory movements to freshwater ecosystems (Silvano et al 2006), and its capture is also linked to spawning events in the coastal zone (Able 2005).…”

“…Small-scale fisheries frequently exploit environments that have a high degree of aquatic and fish biodiversity, and these fisheries involve fishing for consumption and sale (McClanahan et al 2006, Begossi et al 2012a. However, there is evidence that even artisanal fishing can impact target fish populations (Pinnegar and Engelhard 2008).…”

“…However, there is evidence that even artisanal fishing can impact target fish populations (Pinnegar and Engelhard 2008). Artisanal fisheries account for about 50% of the overall Brazilian fish catch, but there is a scarcity of basic data on these catches, which is an obstacle for making temporal comparisons (Begossi et al 2012a). Also, there is often no information available about the status of vulnerable species that are commercially important (Begossi et al 2012b).…”

Summary:In this study, we used microsatellite markers to examine the genetic structures of Centropomus undecimalis (Bloch, 1792) and Epinephelus marginatus (Lowe, 1834) populations collected from artisanal fishing sites along a stretch of coastline in southeastern Brazil. Based on F-statistics, there was no significant genetic differentiation evident in any C. undecimalis samples (F ST =0.012). However, Bayesian clustering, principal component analysis (PCA) and discriminant analysis of principal components (DAPC) results suggested that there were most likely two clusters, with no relation to geographic areas. The bottleneck results showed no significant values and the effective population sizes (N e ) for the two genetically differentiated groups were large and similar. In contrast, for E. marginatus populations, the microsatellite loci showed no population subdivisions. The F ST value was low and non-significant (F ST =0.008), a Bayesian analysis indicated one cluster, and a PCA showed that all samples from different geographical sites shared the same genetic structure. The bottleneck results exhibited significant differences, and a low N e was observed. The results of the genetic study of these two species along the southeastern Brazilian coast suggest that the distinct genetic structure of each species should be taken into account as management units for the conservation of their genetic diversities.Keywords: small-scale fisheries; microsatellites; genetic diversity; common snook; dusky grouper; bottleneck. Estructura genética poblacional de dos especies piscícolas, una de estuario y una de arrecife, explotados por la pesca artesanal brasilera Resumen: En este estudio se han utilizado marcadores microsatélites para examinar la estructura genética de Centropomus undecimalis (Bloch, 1792) y Epinephelus marginatus (Lowe, 1834) en localidades de pesca artesanal localizadas a lo largo de la costa del sudeste de Brasil. Los estadísticos de diferenciación poblacional (F-statisctics) no presentaron diferenciación genética entre las muestras de C. undecimalis (F ST =0.012). Sin embargo, los resultados de los análisis basados en clústeres bayesianos, componentes principales (PCA) y análisis discriminante de componentes principales (DAPC) sugieren la posible presencia de dos clústeres diferenciados genéticamente, pero sin ninguna relación con las áreas geográficas. Los resultados del análisis de cuello de botella poblacional no son significativos con valores de tamaño efectivo poblacional (N e ) elevados y similares entre los dos clústeres. Por el contrario, en E. marginatus, los análisis basados en microsatélites no muestran ningún patrón de subdivisión genética. El valor de F ST es bajo y no significativo (F ST =0.008), el análisis Bayesiano indicia un solo clúster y el PCA determina que todas las muestras de las diferentes localidades geográficas comparten la misma estructura genética. El análisis de cuello de botella muestra diferencias significativas con la observación de una baja N e . Los resultados de los anál...
