| The fishing activity on Argentine anchovy Northern stock (34º S-41º S) during the 1993-2011 period was studied (SW Atlantic Ocean, Argentine Sea). The basic data derived from the commercial fleet catch records. Annual landings reached a minimum of 5,900 t in 1999 and a maximum of 36,300 t in 2004. The largest catches, performed by the offshore ice chilling fleet, averaged 11,800 t. As of 2003 it was observed an increase in the coastal ships share and a decrease in that of the inshore fleet that in 2004-2011 represented less than 3% of total landings. The major activity, developed between 37º S-41º S in the August-November period, had Mar del Plata as the main port of landing. The average catch per trip and the mean HP of ships, that as of 1999 increased in... |

| Advise on Biologically Allowable Catch (BAC) for Southern Argentine anchovy (Engraulis anchoita, 41° S-48° S) during 2012. To assess the evolution since 1990 and the current status of Argentine anchovy Southern stock, an Age Structured Population Model (ASPM) was used. Modeling of catches according to a four-month period pulses allowed to predict annual yields so as to get them close to the nominal catches officially recorded. Some independent indexes of stock abundance (eight acoustic estimates of total biomass and five estimates of spawning stock biomass obtained with the Daily Egg Production Method) and the proportion of individuals per age group assessed during the same cruises were used to calibrate the fitting. No stock-recruitment function but a... |

| La squille Squilla mantis (L., 1758) est un Stomapode très abondant le long des côtes tunisiennes. Cette ressource benthique est considérée comme rejet et elle n’est pas exploitée en Tunisie par défaut de tradition de consommation. La haute valeur commerciale de la squille sur les marchés internationaux incite à viser la pêche de cette espèce en vue de l’exporter. Ce travail représente la première base de données se rapportant à l’éco-biologie et aux qualités biochimiques de la squille S. mantis des eaux tunisiennes. Il a pour objectifs la connaissance des aspects relatifs à la biologie de la squille, notamment sa distribution, sa reproduction, sa croissance, ainsi que les opportunités d’exploitation de cette ressource. Dans cette étude, on a analysé les... |

| Se evalúan los stocks desovantes de anchoveta y sardina común mediante la aplicación del método de la producción diaria de huevos, durante la época de máxima actividad reproductiva del año 2003. Se diseñó un crucero de recolección de huevos y se efectuaron capturas de adultos de ambas especies entre la V (33°10’S) y X (41°20’S) Regiones. En la región costera entre la VIII y X Regiones, la condición reproductiva fue monitoreada a través de indicadores macroscópicos (IGS y estados de madurez sexual), indicando que ambas especies habrían iniciado su actividad reproductiva a partir de julio de 2003, con un máximo de actividad observado en septiembre para ambas especies. Desde la flota artesanal con puerto base en Calbuco, se obtuvieron hembras de sardina común... |

| As part of the research programs performed yearly at the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP, Mar del Plata, Argentina) some important basic data about the commercial fisheries usually included in internal reports are registered. This formal paper is a review and summary of size and age composition estimates of commercial catches (discards included) of Northern Argentine anchovy (34ºS-41ºS) obtained between 1990-2011. The basic data resulting from the examination of 521 samples from fishing vessels included 62,466 fish length measurements and 26,667 valid age readings from which the corresponding 22 annual age-length keys were built. The annual estimates of the individual total length-total weight relation parameters and of... |

| This paper deals with the commercial landings of bonaerensis anchovy at the Port of Mar del Plata (Buenos Aires province,Argentina), during the years 1986 to 1990. The mean catch was 15,501t per year. A total of 59 fish samples were taken for total length distributions (N=20164), and 24 sub-samples (N=2370) were analyzed to record individual data (length, weight, sex, sexual stage, age fromotoliths reading). The numer of fish per kg ranged between 28 and 53(mean=34.6). The mean size was 156.63 mm, and the most abundant fish in the landings were those being 3 and 2 years old, as it was also recorded during the period 1980-1985. Ordinary length-weight relationships by season were fitted, and the results were as follows:1) Autumn-Winter: W=8.5* 10-7* L3.392;... |
