| Résumé : Les 6 campagnes de chalutage réalisées en 1987 et 1988 ont permis d’évaluer les indices d’abondance des diverses ressources démersales, essentiellement poisson et céphalopodes, par strate, zone et, pour l’ensemble du plateau continental. Des estimations de biomasse apparente (77'000 tonnes en 1988) et de potentiel maximum exploitable (59'200 t. en 1988) ont aussi été avancées. La comparaison de ces résultats avec ceux des années 1982-1984 a fait ressortir une nette tendance à l’amélioration générale depuis 1987. Si la situation de la zone nord (Cap Blanc) demeure encore préoccupante par rapport à celle du sud, l’abondance globale des ressources du plateau a retrouvé un niveau peu inférieur à celui des années 1982-1983. L’influence probable de... |

| 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... |

| 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... |

| Résumé : Le présent article donne une description de l’évolution des paramètres descripteurs de la pêcherie de céphalopodes. Il utilise les statistiques de pêche du CNROP. Les paramètres décrits sont l’effort (nombre de licences, caractéristiques physiques des bateaux, jours de pêche), les captures et les prises par unité d’effort. Les débarquements totaux ont enregistré une hausse atteignant 42000 tonnes en 1992. Cette hausse est due à celle des rendements importants observés pour le poulpe ; ceux des poissons ont diminué continuellement depuis 1990, notamment chez les glaciers. L’effort, en jour de pêche, a enregistré une baisse progressive pour les congélateurs. Par contre, il a presque doublé de 1990 à 1991 chez les glaciers. Les deux modes de... |

| 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... |

| The demersal phase (from june 24th to 09th, 1995) of cruise T95/06/02 DO, covered an area of 23833,6 km2 between 01° 04'1”N - 79° 59'6”O and 03° 22'7”S - 80° 48'0”O, of the Ecuadorian Continental Plataform, the deph range from 13 to 111 meters. 161 species were recorded, divided into 106 oseum fish species, five sharks, nine ray, 37 crustaceans, three molluscan and one holothurid (sea cucumber). Total biomass was estimated as 91685, 5 t, with 68,72% of this biomass distributed between 02° 15'1”S - 03°22'7”S, opposite to Guayaquil Gulf. The most abundant species were: Gallineta (Prionotus stephanophrys) (37283,7 t), Barriga juma (Larimus spp) (16146,2 t), Perela (Paralabrax spp) (14053,4 t), Palometa (Peprilus medius)(9865,3 t) and Cabezudo (Caulolatilus... |

| 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... |

| The stock estimates obtained during the demersal fish resources survey in 1980-1985 were used to estimate the potential yields of demersal stocks of the Ecuadorian Continental Shelf. The difficulties of predicting yields for multispecies fisheries are discussed and modified version of the Gulland model was adopted. The potential realizable yields for multispecies fisheries are discussed and a modified version of the Gulland model was adopted. The potential realizable yield was calculated to be between 15,000 t and 20,000 t per year, of which 2,000 t is good quality fish, 5,000 t per year of small and medium fish and 8,000 t of gurnards. The majority of these resources are at present being fished at around their optimum levels and any further developments... |
