Provedor de dados: 72
Autores: Espíndola,Fernando; Yáñez,Eleuterio; Böhm,Gabriela.
Se usó el modelo lineal generalizado (MLG) para estandarizar el índice de abundancia relativa, captura por unidad de esfuerzo (CPUE) de anchoveta (Engraulis ringens), sardina (Sardinops sagax) y jurel (Trachurus murphyi), en la zona norte de Chile (18º21-24ºS), entre 1987 y 1997. Para la anchoveta se toma en cuenta la categoría de embarcación, la zona de pesca, la fase lunar, la estación del año, el año y la temperatura superficial del mar (TSM). En tanto que para la sardina y el jurel se toma en cuenta la categoría de embarcación, la zona de pesca, la fase lunar, la estación del año y el año. Estas variables muestran en general efectos bastante significativos en el logaritmo de la CPUE. Además, interacciones significativas son identificadas para la...

Analyse des données de pêches à pied traditionnelles et de chasse sous-marine, pratiquées en 2008 et 2009 dans la Réserve Naturelle Marine de La Réunion
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Cadet, Christophe.
The Réserve Naturelle Marine (Natural Marine Reserve) of La Réunion island has been created recently (2007) for managing the coral reef of La Réunion West coast. In this area, traditional shore fisheries and spear-fishing are now regulated, controlled and under scientific survey in order to optimize the management of these fisheries, mainly leisure activities. This report draws up a first evaluation of the Reserve eco-guards monitoring in 2008-2009 over these fisheries, with double aim of :  - improving the methodology : sampling strategy, terminology standardization ; data base setting up ;  - collecting a data series for future evolution survey and comparisons with previous data (before creation of the Reserve).  According to the collected data, the...

Statistics of the European and associated purse seine and baitboat fleets, in the Atlantic Ocean (1991-2017)
Provedor de dados: 5
Autores: Pascual-alayon, P; Floch, Laurent; N'Gom, F; Dewals, P; Irie, D; Amatcha, Ah; Amande, M-j.
The document presents an overall summary of the fishing activities of the European and assimilated purse seine and bait boat fleets operating in the eastern Atlantic Ocean over the period 1991-2017. We describe the annual changes in fleet technical characteristics (carrying capacity, size), fishing effort (fishing and searching days), extent of fishing grounds, catches and nominal Catch per Unit Effort by species, as well as the average individual weight by species. Maps are also presented indicating the fishing effort distribution in the Atlantic, as well as the spatio-temporal distribution of European and assimilated purse seine catches in 2017 compared to previous years (2010-2016).

The stocks of whiting (Merlangius merlangus), pollack (Pollachius pollachius) and striped red mullet (Mullus surmuletus), are considered by ICES as Data Limited Stocks (DLS) for the Bay of Biscay areas, those bordering the Iberian Peninsula as well as the Celtic Sea for red mullet. In the case of insufficient data for an analytical assessment, ICES has recommended, for 2013 and 2014, to precautionarily reduce landings by 20 % compared to the period 2009-2011 for these 3 stocks. In order to improve knowledge to fill the gaps in the status of these stocks, and to extract them from the DLS category, the ROMELIGO project has: i) analyzed available data on both catches and professional fishing activity, Captures per Unit of Effort (CPUE) to identify reference...

Investigating the performances of a bayesian biomass dynamic model with informative priors on Atlantic bluefin tuna
Provedor de dados: 5
Autores: Simon, M; Fromentin, Jean-marc; Bonhommeau, Sylvain; Gaertner, Daniel; Etienne, Marie-pierre.
We examined the possibility of eliciting informative priors for the parameters of a biomass production model with emphasis on the intrinsic population growth rate of Atlantic bluefin tuna (Thunnus thynnus). We reviewed the literature to propose probability distribution functions for the vital rates and used a matrix population model structured by age (Leslie) to compute the population growth rate. A generalized biomass production model is applied on two CPUE and catch datasets (1976-1996 and 1976-2006) using informative priors. The population growth rate prior has a diffuse distribution and is very sensitive to young of the year mortality rate. Thus, we compared the performances of this prior with a commonly used prior for tunas population growth rate. We...

Suivi des pêches à pied traditionnelles et de la chasse sous-marine de 2008 à 2011 dans la Réserve Naturelle Marine de La Réunion
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Cadet, Christophe; Turban, Stéphanie; Le Bonniec, Stephanie.
The recent creation of the Réserve Naturelle Marine (Natural Marine Reserve) of La Réunion (RNMR) island in 2007 has provided a legal status to the traditional coastal fisheries and to the spear-fishing operating on the coral reef habitat. This legal frame implies fisheries surveillance and patrolling along with scientific surveys and monitoring, such as the "PechTrad" collaborative project, lead jointly by the RNMR and the French Research Institute for Exploration of the Sea (Ifremer). Four types of fisheries are allowed with specific regulation on the coral reef ecosystem and are analysed here after a 4-year survey (2008-2011): the beach seine targeting the yellowstripe goatfish (Mulloidichthys flavolineatus), the octopus shallow water collecting, the...

Contribution à l'étude de la biologie et de la pêche du rouget-barbet (Mullus surmuletus) dans le Golfe de Gascogne
Provedor de dados: 5
Autores: Tous, Philippe.
The growth study of s tripped Mullet, from the Bay of Biscaye, from April to June is managed by scale reading. Sorne difficulties appear with the interpretation female scales. The Analysis of ovaries confirms that spring is the period of reproduction, and shows that the age of first reproduction is two year (65 %) or one year old (35 %). Secondly, the exploitation of various statistic data shows the evolution of landings of Stripped Mullet in several harbours, and especially in les Sables d'Olonne, since 1962.  The reconstitution of the artisan trowlers effort in this harbour confirms the long decline of c.p.u.e . for Mullus surmuletus, and a rapid increase since 1981. The problem of the lack of data about the inshore fishery and about the composition of...

Provedor de dados: 49
Autores: Araújo,Túlio Raimundo de; Ribeiro,Ariana Cella; Doria,Carolina Rodrigues da Costa; Torrente-Vilara,Gislene.
Belmont Stream is the main tributary of the Madeira River in the area immediately downriver from the Santo Antonio Fall. Samplings were carried out using gill nets in the mouth of this stream between May 2005 and April 2006 and resulted in a list of 74 species. The analyses included values of composition, constancy of occurrence, species richness, abundance, Catch Per Unit of Effort and trophic structure about the ten most abundant species. Characiformes and Siluriformes were dominant order in the samples and Curimatidae (popularly known as "branquinhas") was the most abundant family, represented by Psectrogaster rutiloides (32.57% of the collected specimens), Potamorhina altamazonica (10.72%), and Potamorhina latior (7.79%). The most of species were...
