First records of dusky grouper Epinephelus marginatus settlement-stage larvae in the Ligurian Sea
Provedor de dados: 5
Autores: Faillettaz, Robin; Gilletta, Laurent; Petit, Franck; Francour, Patrice; Irisson, Jean-olivier.
The presence of dusky grouper Epinephelus marginatus settlement-stage larvae in the Ligurian Sea is reported. Epinephelus marginatus populations are slowly recovering along the french Mediterranean coast since the establishment of a moratorium on spearfishing in 1993 but still remain spatially restricted to marine protected areas. The occurrence of Epinephelus marginatus larvae in a region where effective settlement had not been detected for decades is a new observation supporting the species’ recovery.

Premier signalement de Epinephelus marginatus (Serranidae: Epinephelinae) en Manche orientale. Le premier signalement du mérou noir Epinephelus marginatus (Lowe, 1834) en Manche orientale est rapporté. Un spécimen a été capturé le 10 juin 2011 en baie de Seine. Il mesurait 66 cm et pesait 5,5 kg. D'après l'étude des écailles, il s'agissait d'une femelle adulte âgée de 12 ans qui n'avait pas effectué sa croissance dans la Manche, ce qui confirme le fait d'une observation occasionnelle et non le signe d'une extension d'aire de répartition avec une population établie.

Additive effects of climate change on connectivity between marine protected areas and larval supply to fished areas
Provedor de dados: 5
Autores: Andrello, Marco; Mouillot, David; Somot, Samuel; Thuiller, Wilfried; Manel, Stephanie.
AimTo study the combined effects of climate change on connectivity between marine protected areas (MPAs) and larval supply to the continental shelf. LocationThe Mediterranean Sea, where sea surface temperatures are expected to strongly increase by the end of the 21st century, represents an archetypal situation with a dense MPA network but resource overexploitation outside. MethodsUsing an individual-based mechanistic model of larval transport, forced with an emission-driven regional climate change scenario for the Mediterranean Sea, we explored the combined effects of changes in hydrodynamics, adult reproductive timing and larval dispersal on the connectivity among MPAs and their ability to seed fished areas with larvae. ResultsWe show that, over the...

Autores: Albouy, Camille; Mouillot, David; Rocklin, Delphine; Culioli, Jean M.; Le Loc'H, Francois.
Marine protected areas (MPAs) have the potential to enhance the long-term sustainability of coastal resources, and the artisanal fisheries which depend on them. However, recreational fisheries, which are increasing their impacts on coastal resources worldwide, may reduce the benefits that MPAs provide to declining artisanal fisheries. Here we used the Bonifacio Straits Natural Reserve (BSNR) Corsica as a study case to simulate the combined effects on coastal resources of artisanal and recreational fishing efforts. The BSNR ecosystem was modelled using mass-balance modelling of trophic interactions. This model was compared to another built on a non-protected area from the same region. We aggregated fishing fleets into artisanal and recreational categories,...

Activity, habitat use, feeding behavior, and diet of four sympatric species of Serranidae (Actinopterygii: Perciformes) in southeastern Brazil
Provedor de dados: 83
Autores: Gibran,Fernando Zaniolo.
Diplectrum formosum (the sand perch), Diplectrum radiale (the aquavina), Epinephelus marginatus (the dusky grouper) and Mycteroperca acutirostris (the comb grouper) are four sympatric serranid of remarkable ecological and commercial importance. This study investigated the feeding of these four species in the São Sebastião Channel, São Paulo State (southeastern Brazil), comparing their diet, habitat utilization and morphological features related to foraging. These four serranids are opportunistic visual predators that use a total of nine different tactics to capture their preys, feed mostly on crustaceans during the day and twilight, and keep stationary and quiescent at night. The ecomorphological study was conducted to test its predictive value to infer...

Age, growth, and reproductive aspects of the dusky grouper Mycteroperca marginata (Actinopterygii: Epinephelidae) in a man-made rocky habitat in southern Brazil
Provedor de dados: 83
Autores: Seyboth,Elisa; Condini,Mario V; Albuquerque,Cristiano Q; Varela Jr,Antônio S; Velasco,Gonzalo; Vieira,João P; Garcia,Alexandre M.
The dusky grouper, Mycteroperca marginata, is an important commercial marine fish that is currently considered an endangered species worldwide and listed as overexploited in Brazil. Although its reproductive biology has been studied elsewhere, no information is available for populations in its southernmost distribution limit on the Brazilian coast. The present work investigates age structure, growth and reproduction of individuals inhabiting a pair of rocky jetties, about 4.5 km long each, located in the mouth of Patos Lagoon in the municipality of Rio Grande, in the southwestern Atlantic Ocean. A total of 130 individuals obtained between February 2007 and May 2009 were analyzed, with total length ranging from 260 to 800 mm. The growth coefficient found in...

Diet and feeding strategy of the dusky grouper Mycteroperca marginata (Actinopterygii: Epinephelidae) in a man-made rocky habitat in southern Brazil
Provedor de dados: 83
Autores: Condini,Mario V.; Seyboth,Elisa; Vieira,João P.; Garcia,Alexandre M.
The dusky grouper (Mycteroperca marginata) is a marine species usually associated with rocky bottoms and reefs. The present work investigated the diet and feeding strategy of a dusky grouper population inhabiting a 4.5 km long pair of rocky jetties located in the mouth of Patos Lagoon estuary. No prior research has been conducted in such man-made habitat and the current study provides a basis for comparative studies on the diet of the dusky grouper populations inhabiting natural vs. man-made rocky habitats. Similarly with previous studies on natural substrates, crabs and fishes were the main food categories consumed (%IRI = 85.1 and %IRI = 12.6, respectively), whereas shrimps and mollusks had lower importance in the diet (%IRI = 1.9 and 0.4, respectively)....

Autores: Andrade,Áthila Bertoncini; Machado,Leonardo Francisco; Hostim-Silva,Maurício; Barreiros,João Pedro.
Investigations were carried out about the reproductive biology of the dusky grouper, Epinephelus marginatus (Lowe, 1834) a serranid protogynous hermaphrodite fish inhabitant of rocky bottoms from shallow waters up to 200 m depth. Samples were caught in the islands that form Arvoredo Biological Marine Reserve (SC - Brazil) and the coastal islands near Florianópolis region from March 1998 to May 2000. Data from samples of juvenile groupers on intertidal pools were used to link their occurrence in the pools to the post-spawning season. To describe the histological changes on gonads along the reproductive cycle and to establish maturation scales, 109 groupers were histologically tested for sex determination. First maturation size was determined for females...
