A large oceanic puffer fish rare in tunisian waters OceanDocs
Nakamura, I.; Hattour, A.; Nguira, A..
On January and April, 2004, 4 large oceanic puffer fish (total length 45 to 73.5 cm with body weight 1.12 to 3.2 kg) was caught by the small trammel net, off Tunisian coasts (gulf of Tunis, Monastir and Salakta) and brought into INSTM for the identification. It is a fish belonging to the family of Tetraodontidae, Lagocephalus lagocephalus (Linnaeus). This paper is dealing with the description and some measurement and meristic characters of this specie, which is not a common animal, fished by the Tunisian professional fishermen.

Acoustic surveys on the southern blue whiting (Micromesistius australis). OceanDocs
Madirolas, A..
Two joint Argentine-British acoustic surveys specifically targeted on the southern blue whiting (Micromesistius australis) were carried out during September 1994 and 1995. The surveys confirmed the existence of a spawning concentration area located south from San Carlos Strait, in waters south of Malvinas Islands, ASW. The obtained point estimates of blue whiting abundance were 84801 t for the 1994 survey and 140953 t for the 1995 survey. The surveys also provided information on the school structure and behavior as well as some clues about the complex migration pattern of the species.

Análisis de la distribución y dinámica poblacional de lenguados de la Provincia de Buenos Aires (Pisces, Bothidae) OceanDocs
Fabré, N.N..
Los lenguados constituyen un importante recurso pesquero en el Mar Argentino. Más que en los volúmenes desembarcados (9 .731 t en 1991), esta importancia se centra en su elevado valor de comercialización debido a la alta calidad de su carne. Atendiendo a los desembarques totales realizados en el Mercado de Concentración Pesquera de Mar del Plata, los lenguados ocupan el octavo lugar. Estos desembarques están compuestos principalmente por especies de porte mediano a grande pertenecientes al género Paralichthys, y por ejemplares de tamaño mediano o pequeño de las especies Xystreuris rasile, y en menor proporción, Paralichthys isosceles. Este recurso es explotado, en el sector bonaerense, por las flotas de rada o ría y costera, mientras que la flota de altura...

Analyse de la variabilité spatio-temporelle des populations microalgales côtières observées par le REseau de surveillance du PHYtoplancton et des phycotoxines (REPHY) ArchiMer
Gailhard, Isabelle.
The dynamic of coastal marine microphytoplankton communities is characterized by successions of species assemblages displaying typical schemes of spatio-temporal variability. Numerous studies of phytoplankton spatio-temporal variability have concerned holistic variables such as total biomass or primary production. Such studies deal with the role of primary producers in the global functioning of the pelagic ecosystem, but have little relevance to other problematics. For instance, knowledge of the taxonomic composition of phytoplankton communities and of their spatio-temporal patterns is necessary to understand the mechanisms favouring of the predominance of a precisely identified population within phytoplankton communities. In particular, the identification...

Aspectos atuais da distribuição geográfica de Anopheles (Kerteszia) cruzii Dyar & Knab, 1908 no estado do Espírito Santo, Brasil Entomología
Rezende,Helder Ricas; Cerutti Junior,Crispim; Santos,Claudiney Biral dos.
Anopheles cruzii was registered in Espírito Santo state both in 1957 and 1968. Our study provides additional evidence of its presence, including municipalities that were non mentioned before. Anopheles captures undertaken between 1998 and 2003 pointed out a distribution restricted to the forested outskirts of the mountains in the highland area of the state. Its epidemiological role is suggested by the simultaneous presence of malaria cases in the same municipalities.

Aspectos biológico-pesqueros de la merluza de cola del Atlántico Sudoccidental OceanDocs
Bezzi, S.I..
The distribution areas and population structure of the long-tailed hake are analized. Data come from fisheries research cruises carried out by RV Walther Herwig and Shinkai Maru in the Argentine Sea in 1978/79. Macruronus magellanicus is a typical cold waters species of the Southwest Atlantic and Southeast Pacific Oceans. Maximum concentrations were found in the southern Patagonian shelf, in coastal waters and in depths below 200 m. Spawning individuals were observed on the continental slope in the southern extreme of the Patagonian shelf (54°). The distribution area extend to 93,439 n mi² in spring and to 12,368 n mi² in summer.

Renzi, M.A..
The kingklip is one of the species that has been traditionally exploited in the Argentine Sea. Although captures were not very important, they have been increased in the last years. In this paper, the structure of the concentration areas of summer, spring and winter distribution and other biological aspects were analyzed, on the basis of the data collected during cruises carried out by R/V"Walther Herwig" and R/V"Shinkai Maru" in Argentine waters during 1978/79. The trophic spectrum of the kingklip comprises mainly food species of the Classes Pisces and Crustacea as well as other complementary groups like Mollusca, Brachiopoda and haliacea.

Aves de la parte baja del Río Sinú, Caribe colombiano; inventario y ampliaciones de distribución OceanDocs
Estela, F.A.; López-Victoria, M..
Knowledge of the geographical distribution of the birds in the Colombian Caribbean is still meager. Coastal wetlands are among the less studied environments in the area and one of the most important for their high bird richness. Since 1998, inventories and monitoring of the bird populations of the lower part of the Sinú river have been made. Until July 2005, 296 bird species have been recorded for the area, 41 of which are new for this part of the Caribbean; in addition, new wintering localities were noted for eight migratory species. Breeding records were obtained for 98 species. Three species are threatened at some level and six have a restricted geographic distribution. New records for the area are explained in terms of the limited previous knowledge of...
