A new species of dwarf sea bass, genus Serranus (Serranidae: Actinopterygii), from the southwestern Atlantic Ocean Neotropical Ichthyology
Carvalho Filho,Alfredo; Ferreira,Carlos Eduardo Leite.
Serranus aliceae n. sp. is described from Rio de Janeiro and Espírito Santo States, southeastern Brazilian coast. The species is readily distinguished from its congeners by the following combination of characters: scales around the caudal peduncle 20 or 21; total gill rakers on first branchial arch 23-29; cheek-scales rows 5 or 6; and by the coloration of live specimens, which are reddish with a broad, conspicuous, white stripe from post-orbital region to the caudal-fin base and a white abdomen. The new species apparently inhabits the deeper (30 or more meters) portions of reef environments along the subtropical Brazilian coast, and is possibly associated with upwelling cold-water masses. The species was observed hovering above rocky bottoms, feeding on...

A process‐based model supports an association between dispersal and the prevalence of species traits in tropical reef fish assemblages ArchiMer
Donati, Giulia Francesca Azzurra; Parravicini, Valeriano; Leprieur, Fabien; Hagen, Oskar; Gaboriau, Theo; Heine, Christian; Kulbicki, Michel; Rolland, Jonathan; Salamin, Nicolas; Albouy, Camille; Pellissier, Loïc.
Habitat dynamics interacting with species dispersal abilities could generate gradients in species diversity and prevalence of species traits when the latter are associated with species dispersal potential. Using a process‐based model of diversification constrained by a dispersal parameter, we simulated the interplay between reef habitat dynamics during the past 140 million years and dispersal, shaping lineage diversification history and assemblage composition globally. The emerging patterns from the simulations were compared to current prevalence of species traits related to dispersal for 6315 tropical reef fish species. We found a significant spatial congruence between the prevalence of simulated low dispersal values and areas with a large proportion of...

A Review on the Ecology, Exploitation and Conservation of Reef Fish Resources in Mozambique OceanDocs
Pereira, M.A.M..
Coral and rocky reefs are very important ecosystems in terms of their diversity, productivity, abundance and beauty. Mozambique possesses extensive reef areas, where fish fauna is the main exploited resource. Nevertheless, the ecology of these resources is little studied. A recent report listed 794 reef-associated fishes known to occur in Mozambican coral and rocky reefs. This is a first accountancy of the high fish diversity of Mozambican reefs, which must be assessed. Reef-associated fish resources exploitation is conducted at three basic levels: (i) subsistence (artisanal fishery); (ii) commercial exploitation (semi-industrial reef fishery, ornamental fish trade and recreational diving); and (iii) sports fishing. Presently, the artisanal fishery is the...

Characterization of thirteen new polymorphic microsatellite markers from the honeycomb grouper Epinephelus merra ArchiMer
Muths, Delphine; Bourjea, Jerome.
Epinephelus merra (Serranidae) is the most common and widespread species of this genus, mostly found in reef habitats from South Africa to Central Pacific. Thirteen polymorphic microsatellite loci were isolated and characterized from this species. Polymorphism was studied in two localities from the Comoros archipelago-Moh,li and Moroni. Allelic diversity was 7.5, polymorphism ranging from 3 to 13 alleles. Overall heterozygosity was high with an average observed heterozygosity of 0.587. Three of these loci were characterised by heterozygote deficiencies for both populations. Finally, ten of the 13 developed primers could be used in future population genetics study of E.merra that might be useful in a context of marine biodiversity conservation.

Comparative phylogeography of the western Indian Ocean reef fauna ArchiMer
Borsa, Philippe; Durand, Jean-dominique; Chen, Wei-jen; Hubert, Nicolas; Muths, Delphine; Mou-tham, Gerard; Kulbicki, Michel.
Assessing patterns of connectivity at the community and population levels is relevant to marine resource management and conservation. The present study reviews this issue with a focus on the western Indian Ocean (WIO) biogeographic province. This part of the Indian Ocean holds more species than expected from current models of global reef fish species richness. In this study, checklists of reef fish species were examined to determine levels of endemism in each of 10 biogeographic provinces of the Indian Ocean. Results showed that the number of endemic species was higher in the WIO than in any other region of the Indian Ocean. Endemic species from the WIO on the average had a larger body size than elsewhere in the tropical Indian Ocean. This suggests an...

Coral reef fish assemblages of Baie Ternay National Marine Park and Baie Beau Vallon, Mahé, Seychelles OceanDocs
Pittman, S.J..
The two most important foreign exchange earning activities in the Seychelles are tourism and fisheries and therefore, the coastal areas and their management are of the greatest importance to the Seychelles government (Khadun, 1991). In recent years government policy has encouraged marine conservation (Procter, 1970; 1984-1989 National Development Plan) and is part way to fulfilling the programme outlined in the Environmental Management Plan of the Seychelles (EMPS, 1990-2000). To date, five marine areas have been designated as national marine parks covering about 23 000 ha with several more proposed parks and protected areas. However, financial constraints, a deficit of qualified personnel, lack of boundary delimitation, inadequate legislation and...

Efecto del alga invasora Undaria pinnatifida sobre la comunidad de peces de arrecife en los golfos Norpatagónicos OceanDocs
Irigoyen, A.J..
This study investigates the impact of Undaria pinnatifida on the reef fish assemblage associated with the coastal rocky reefs of Golfo Nuevo in northern Patagonia, Argentina. Undaria pinnatifida is a laminarian kelp, indigenous to the temperate regions of Japan, China and Korea. It has spread around the world by international shipping and has also been introduced in some regions for mariculture. Its expansion into the northern Patagonian gulfs and Peninsula Valdes, a UNESCO Natural Heritage Site, may threaten eco-tourism activities that depend on local biodiversity and the esthetic quality of the ecosystem. In particular, there is concern about the impact of Undaria on a variety of recreational activities including diving, angling and spear fishing, which...

Ensamblajes de peces arrecifales del área de Santa Marta y el Parque Nacional Natural Tayrona OceanDocs
Olaya-Restrepo, J.; Reyes-Nivia, M.C.; Rodríguez-Ramírez, A..
Los ensamblajes de peces arrecifales del área de Santa Marta y del Parque Nacional Natural Tayrona (PNNT) se caracterizaron a partir de la riqueza, diversidad, equitatividad, abundancia relativa (AR) y frecuencia de observación (FO) y se evaluó el posible efecto del PNNT sobre dichos atributos. La información se obtuvo en 20 estaciones mediante el censo de buceo errante (30 minutos). Se encontraron un total de 180 especies de peces. Los análisis de varianza indicaron que el PNNT al parecer ha tenido un efecto sobre la diversidad y equitatividad de especies (p< 0.05) mientras la riqueza es similar a lo largo del área estudiada. En términos de composición, se encontró que las dos zonas evaluadas presentan una moderada similaridad (Índice de Jaccard 0.69)....

Ensambles de peces en los arrecifes norpatagónicos: diversidad, abundancia y relaciones tróficas y con el hábitat OceanDocs
Galvan, D.E..
This study describes the structure and seasonal dynamics of the reef fish assemblages that inhabit the Nuevo and San José gulfs of the Argentine coast. It analyzes relationships between the structure of the assemblage and several habitat variables, with emphasis on shelter availability and refuge characteristics. The diets and feeding strategies of the most conspicuous fish species are described and their impact on the density of one of their preys is evaluated. The northern Patagonian gulfs are in a temperate region (41° – 43° Lat. S) and are characterized by large extensions of sandy bottoms scattered by patches of rocky outcrops that form reefs. The fish assemblage associated to these reefs is low in species richness and has components of the...

Estimation des stocks de poisson des lagons de Nouvelle-Calédonie : 1 – Structure et stocks des communautés des poissons de récifs. ArchiMer
Letourneur, Y; Kulbicki, M; Labrosse, Pierre.
Lagoon fish in New Caledonia are mainly caught by artisanal fisheries and subsistence fishing. Reef fish are the major component of this catch. The present study aimed at estimating these reef fish standing stocks and at finding the main factors influencing the distribution of these fish. Sampling of 904 stations was stratified according to three zones (north, east and west) and three reef types (barrier, intermediate and fringing). Fish communities exhibited strong heterogeneity in their distribution, showing higher biomass (maximum of 447 g.m(-2)) and total standing stock (43 000 tonnes) in the north zone than in the east and west zones. Similarly, observed patterns were dependent on reef types: higher biomass and total standing stock being observed on...

Genetic structure of the reef grouper Epinephelus merra in the West Indian Ocean appears congruent with biogeographic and oceanographic boundaries ArchiMer
Muths, Delphine; Tessier, Emmanuel; Bourjea, Jerome.
The reef fauna connectivity of the West Indian Ocean (WIO) is one of the least studied globally. Here we use genetic analyses of the grouper Epinephelus merra (Bloch 1793) to determine patterns of connectivity and to identify barriers to dispersal in this WIO marine area. Phylogeographic and population-level analyses were conducted on cytochrome b sequences and microsatellites (13 loci) from 557 individuals sampled in 15 localities distributed across the West Indian Ocean. Additional samples from the Pacific Ocean were used to benchmark the WIO population structure. The high level of divergence revealed between Indian and Pacific localities (of about 4.5% in sequences) might be the signature of the major tectonic and climatic changes operating at the...

Las vacas imitadores expertos OceanDocs
Chevalier, Pedro.
La mayoría de las especies del género Hypoplectrus presentan un comportamiento conocido como mimetismo agresivo. Este fenómeno consiste en la imitación de los patrones de coloración, por parte de las vacas, de peces que no son depredadores de crustáceos y pequeños peces. Al imitar el color de peces inofensivos pueden acercarse a sus presas sin que estas huyan.

Local ecological knowledge on the goliath grouper epinephelus itajara (teleostei: serranidae) in southern Brazil Neotropical Ichthyology
Gerhardinger,Leopoldo Cavaleri; Marenzi,Rosemeri Carvalho; Bertoncini,Áthila Andrade; Medeiros,Rodrigo Pereira; Hostim-Silva,Maurício.
The goliath grouper Epinephelus itajara is a large sized (> 400 kg) and critically endangered marine fish, which is protected in many countries, including Brazil. Through the application of semi-structured interviews, we investigated the local ecological knowledge of seven fishermen specialist on catching E. itajara from the Babitonga bay, Santa Catarina, Brazil. Local long-line fisheries for E. itajara seemed to be a disappearing tradition in the studied site, with a detailed inherent local ecological knowledge system, which is also being lost. Our study also showed that fishermen engaged in recent fisheries, such as spear-fishing, can also possess a detailed local ecological knowledge system. Through the analysis of fishermen local ecological...

Long-term Trends in Coral Reef Fish Yields and Exploitation Rates of Commercial Species from Coastal Kenya OceanDocs
Kaunda-Arara, B.; Rose, G.A.; Muchiri, M.S.; Kaka, R..
Analysis of long-term (1978–2001) marine fisheries data showed that Kenyan coralreefs produced an estimated 2–4 metric t/km2/year of demersal fish. A rapid overall decline in landings occurred during the 1990s. Yields (t/km2/year) showed bimodal peaks in 1982 (2.98) and 1991 (2.90). The average total landings dropped by 55% during the last decade following peak landings in 1982. Landings of the commercially important families (e.g., Siganidae, Lethrinidae, Lutjanidae and Serranidae) declined by about 40% during the last decade, with the groupers (Serranidae) showing the steepest (72%) decline. Analysis of landings per administrative district showed a 78% decline in the densely populated Mombasa district between the periods 1983–1991 and 1992–2001. The less...
