The International Workshop entitled: “Ecosystem Approach to Management of Aquatic Resources: progress, gaps and perspectives” was made possible thanks to the initiative of the Chilean Society of Ocean Sciences (SCHCM) and the Fisheries Development Institute (IFOP). The support and funding provided by the representatives from both agencies is apprec...
Araucanian herring, Strangomera bentincki, is ecologically and economically important. Its complexity, like that of other pelagic fish, arises from seasonal population changes related to distribution with different spatial dynamics and demographic fractions, subject to strong environmental and fishing exploitation variations. This implies the neces...
La realización del seminario internacional: “Manejo de
recursos acuáticos con enfoque ecosistémico: avances,
brechas y perspectivas” fue posible gracias a la iniciativa
de la Sociedad Chilena de Ciencias del Mar y del Instituto
de Fomento Pesquero. Se agradece a los responsables de
ambas instituciones por su apoyo y financiamiento, ya que el
encuen...
El proyecto Supporting the Ecosystem Approach to Fisheries Management Through Scientific Research & Capacity Building in the Framework of Chilean Benthic Fishery Management Committees (abreviado SEAFISHMAN) se propone contribuir a la sustentabilidad de la pesquería asociada a recursos bentónicos, que se encuentran bajo la administración de cuatro c...
Evaluación de stock del langostino amarillo diferenciado por zonas de análisis para establecer cuotas biológicamente aceptables en Chile.
The royal red shrimp (Haliporoides diomedeae) is a penaeidea crustacean specie which is caught as target specie since 2002 by the crustacean trawl fishery operating on the central zone off Chile (32º10S-36º00S). Catch rates of the royal red shrimp were standardized using Generalized Linear Models (GLM). Preliminary analysis on goodness-of-fit ind...
Recent assessments of Chilean shrimp, Heterocarpus reedi, in central Chile have been conducted separately for the northern and southern zones of the fishery and treating them as two separate stocks. However, it is not clear whether H. reedi of the two zones interact with one another or whether they share similar characteristics. Such knowledge is n...
The performances of different sample sizes for estimating the size distribution of squat lobster (Pleuroncodes monodon) catches were analyzed using a computer resampling procedure. The data selected were gathered in May 2002 between 29°10'S and 32°10'S. These data were used to test seven sampling scenarios for fishing trips (1-7 trips), twelve scen...
Stock assessment projects have been carried out by IFOP with the main goal of providing scientific advice for the management decision of the main fisheries resources of Chile. These fisheries resources includes yellow squat lobster Cervimunida johni, an endemic specie distributed from Taltal Port (25°25’S) to Isla Mocha (38°20’S) at depths of 200-4...
An analysis was made of the factors affecting the catch rates of the yellow squat lobster (Cervimunida johni) in Chile´s northern region (26°03´-32°10´S) by reviewing commercial fishing logbooks from 1993 to 2003. Factors evaluated included years, months, depth stratum, fishing areas and fleet characteristics as linear predictors in a generalized l...

Fishery and biological data were updated up to 1997. Catch-at-length compositions and at age were used. CPUE was standardized using GLM. Two stock assessment models were programed. The first model was a statistical catch-at-age analysis (CCAGEAN) that includes fishing purse seiner and trawler fleets, selectivity pattern by fleet and cpue index. The...
