| In the Dermersal Fishing period of the Cruise T94/11/05 D-O (15/11/94-23/11/94) an area of 12,520.9 km2 was covered, that is. The Ecuadorean Shelf between the 02°10'0”S - 80°0'0”W and 14 to 115 meters deep throughout th Ecuadorean Continental Shelf of the Guayaquil Gulf area. A total of 78 species was identified as follows: 74 of this 95%, two of crustaceans, one of molluscan and one of holothurid (Sea cucumber). The estimated total biomass of demersal fish was of 78, 384.9 t, from which the 52% was concentrated between the 02°48'9”S and 03°15'8”S. The most abundant species were: Gallineta (Prionotus stephanophrys)(48,776.0 t), Corvina (Cynoscion spp.) (11,241.7 t), Barriga juma (Larimus spp) (4,111.8 t), Cabezudo (Caulolatilus spp) (2,554.2 t) and Torno... |

| El orange roughy (Hoplostesthus atlanticus, Collet 1889), es una especie de aguas profundas de un alto valor comercial, que presenta una amplia distribucion geografica en los oceanos atlantico, Indico y Pacifico. Los estudios de edad de Orange roughy muestra que es una especie de crecimiento lento que alcanzaria sobre los 100 años de edad. La actividad pesquera en torno a este recurso, de reciente desarrollo en Chile, ha permitido la recolección de muestras de la fauna ictica asociada a esta pesqueríia que reviste especial especial interés cientifico, en áreas como la zoologia y biogeografia , estudios que unidos a datos geologicos pueden contribuir a responder importantes interrogantes como la distribucion de orange roughy en areas geograficas tan... |

| Fishery statistics of austral demersal fishes in the Southwest Atlantic (1980-2002 period). A synthesis of the information available about catches of austral demersal fishes and fishing efforts reported by different fleets that operated in the SW Atlantic between 34° S-58° S in the 1980-2002 period is made. Species included in the analysis were southern blue whiting (Micromesistius australis), patagonian hoki (Macruronus magellanicus), patagonian toothfish (Dissostichus eleginoides), red cod (Salilota australis), southern hake (Merluccius australis) and ling (Genypterus blacodes). Annual and monthly catches, fishing grounds, number of vessels that participated in the fisheries, main landing ports and other characteristic of interest are presented. When it... |

| Nineteen lightday rectangular transects were made 16 in the area of the Gulf of Guayaquil (Ecuador), and 3 in an oceanic area at the west of the Gulf of Guayaquil, this was the second part of research cruise, oriented to the evaluation of the small pelagic fish stocks, it was made between september 14th and 27th, 1995. The SIMRAD EK-500 acoustic system was used, installed on board of the National Research Institute (INP) R/V Tohallí. At the same time, people from the INP's Fisheries Observer Program were on four private enterprises vessels, while they were fishing in the same Gulf's area. They also made the biological sample of the commercial catch, for future relation with the results from the acoustic evaluation. The V/R Tohallí principal catch was jack... |

| Period 1985-2001. A stock assessment of Patagonian hoki of the Southwest Atlantic was carried out by using data from the years 1985-2001. A cohort analysis, fitted with some survey abundance indices was used in an adaptive conceptual framework. Simulation trials were performed to project the evolution of the fishery, to evaluate the risk of over-fish the stock under different exploitation levels, and to estimate Biologically Acceptable Catches (BAC). Both total biomass and spawning stock biomass showed increasing trends resulting from four strong year classes (1993, 1995, 1996 and 1998). Total biomass at the beginning of 2001 was estimated to be 2.5 million tons, and spawning stock biomass at the spawning time (August) was estimated to be around 1.28... |
