“…The latter, is common within scianids (MUNIZ & CHAVES 2008) and results in large numbers of individuals becoming vulnerable to the trawls at once. This observation may be corroborated by the observed noted pulse spawning period in the south between October and December for main species of the Stellifer genus (CHAVES & VENDEL 1997, ALMEIDA & BRANCO 2002 and during spring and summer for P. brasiliensis , ROBERT et al 2007.…”

The present study analyzed qualitatively and quantitatively the temporal and spatial changes in the fish assemblages present in seabob shrimp distribution sites in two important fishing areas of the Santa Catarina coast. Monthly bottom trawls, conducted between March 2007 and February 2008 in Balneário Barra do Sul and Penha, yielded a total of 38,608 specimens belonging to 54 species, of which 35 occurred in both regions. The Sciaenidae was the most represented family in both number of species and abundance of individuals. The dominant species were Stellifer rastrifer (Jordan, 1889), S. brasiliensis (Schultz, 1945), Paralonchurus brasiliensis (Steindachner, 1875), Isopisthus parvipinnis (Cuvier, 1830), Trichiurus lepturus (Linnaeus, 1758), and Pellona harroweri (Fowler, 1917). The ichthyofaunal structure showed a spatiotemporal dependence with significant differences in March 2007 and January and February 2008 between Balneário Barra do Sul and Penha. The main differences were attributed to dominant species, which were responsible for significantly altering the abundance of the assemblages. The species richness was similar in both sites, whereas the diversity and equitability indices showed monthly fluctuation patterns that differed between Balneário Barra do Sul and Penha. The Shannon index differed in August, September and November 2007 and January and February 2008, with an H' ranging from 0.74 to 1.98 influenced by dominant species, whereas significant variations were observed for the Pielou index in November 2007 and February 2008. The Berger-Parker index demonstrated a clear dominance pattern where the monthly numeric contribution of a single species ranged from approximately 30 to 80%. Although the results showed differences between fishing grounds 25% of the time, we conclude that fish assemblies captured as accompanying fauna in artisanal seabob shrimp fisheries showed statistically similar characteristics for most of the year, although Balneário Barra do Sul and Penha are 35 km away from each other

“…The importance of polychaetes in the diet of P. brasiliensis in the ResexCor was similar to that observed off southern Paraná, with FO exceeding 40% (Robert et al 2007) and around 69% in the coast of the State of São Paulo (Jucá-Chagas 1997, Soares & Vazzoler 2001). However, these authors did not observe the same importance that shrimps had in our study area.…”

“…The importance of polychaetes in the diet of sciaenids was also reported by Bertrán et al (2013) for Micropogonias furnieri in Chile. Additionally, Robert et al (2007) and Soares & Vazzoler (2001) observed the presence of fishes in the diet of P. brasiliensis, a food category of minor importance for this species in the ResexCor (0.8%).…”

Resumen.-Larimus breviceps, Isopisthus parvipinnis y Paralonchurus brasiliensis son las 3 especies de Sciaenidae más abundantes en la Reserva Extractiva Marina de Corumbau, en Bahia, nordeste de Brasil. Se analizaron los cambios ontogenéticos y estacionales en las dietas de estas especies. Estos cambios pueden reflejar las adaptaciones y mecanismos de coexistencia utilizados por estas especies. El muestreo se llevó a cabo entre diciembre 2007 y septiembre 2008 con arrastreros. Los peces y las gambas fueron los principales recursos consumidos por estas 3 especies. Para L. breviceps y P. brasiliensis, Sergestidae fue el alimento dominante (junto con poliquetos para el segundo), mientras que los peces fueron el elemento más importante para I. parvipinnis. Se observaron valores bajos de amplitud de nicho para todas las especies. El Índice de Similitud de Morisita indicó baja superposición entre las dietas de las 3 especies en la mayoría de las estaciones del año, a excepción de L. breviceps y I. parvipinnis, que mostraron valores superiores al 80% en todas las estaciones, excepto en verano. Aunque estas especies mostraron diferencias en la posición y orientación de su boca, esencialmente utilizan los mismos recursos. El hábito de alimentación carnívoro, principalmente carcinófago, prevaleció entre los Sciaenidae estudiados.Palabras clave: Hábitos de alimentación, coexistencia, superposición de nicho, amplitud de nicho, nordeste de Brasil Abstract.-Larimus breviceps, Isopisthus parvipinnis, and Paralonchurus brasiliensis are the 3 most abundant species of Sciaenidae in the Marine Extractive Reserve of Corumbau in Bahia (northeastern Brazil). Ontogenetic and seasonal changes in the diet of these species were analyzed. These changes may reflect adaptations and coexistence mechanisms used by those species. Sampling took place between December 2007 and September 2008 with otter trawlers. Fishes and shrimps were the main resources consumed by these 3 species. For L. breviceps and P. brasiliensis, Sergestidae was the dominant food item (together with polychaetes for the latter) and fishes were the most important item for I. parvipinnis. Low values of niche breadth were observed for all species. The Morisita Similarity Index indicated a general pattern of low overlap between the diets of the three species analyzed in most of the seasons, with the exception of L. breviceps and I. parvipinnis, which showed values higher than 80% in all seasons, with the exception of summer. Although these species showed differences in the position and orientation of their mouth, they essentially use the same resources. The carnivorous feeding habit prevailed among the studied Sciaenidae, with predominance of the carcinophagous habit.

Here we examined a carcass of a brown booby found during the monitoring of a beach conducted on northern Rio de Janeiro, Southeastern Brazil. After necropsy, it was concluded that the brown booby choked eating a banded croaker twice as long and five times as heavy as the usual fish consumed by brown boobies.
