Análisis de la flota dedicada a la pesca de corvina rubia y distribución de tallas del desembarque. Período 1992-1995 OceanDocs
Carozza, C.R.; Perrotta, R.G.; Cotrina, C.P.; Bremec, C.; Aubone, A..
This work deals with the structure and efficiency of the fleet fishing white croaker in Argentina. Results show that there exist two strata delimited by 17.25 m length and 345 HP vessels. The most efficient is constituted by those of smaller dimensions. During 1992-1995 landings were sampled and subsequently analyzed. A decrease in mean length landed and an increase of juveniles presence were detected. The situation coincided with an increment of catches, landings, fishing effort, exports and the fleet activities in "El Salado" area (35° 57' - 36° 57' LS).

Aspectos generales de la pesca del bonito (Sarda sarda)en la Argentina OceanDocs
Hansen, J.E..
Basic aspects of the fising of Bonito in Argentina such as: catch statistics, fleet and gears, season and fishing grounds, and catch per unit effort (CPUE)are analized. FAO World Catch Statistics show that none of the different populations of Sarda sarda or other species of the Genus may support a highly productive fishery Exceptions are Sarda chilensis and S.sarda from the Black Sea, which us exploited by Turkey. On the basis of available information it may be inferred that the Bonito of Argentina has more competitors and a narrower thophic spectrum than that from the Black Sea.

El ahorro y rendimiento del combustible en la pesca OceanDocs
Dahle, Emil Aall.
El actual interés en el ahorro de combustible en la pesca se debe principalmente al hecho de que la reciente suba de sus precios es totalmente desproporcionada en relación a la suba de los demás costos, lo que hace que cada vez se más difícil hacer llegar el pescado a la población a precios moderados.

El proceso de pesca en la explotación de la vieira patagónica (Zygochlamys patagonica) y las respuestas espacio-temporales de las poblaciones OceanDocs
Bogazzi, E..
Several attributes of populations of sedentary organisms differentiate benthic fisheries from those approached by the classic theory, inspired by fin-fisheries. The assessment and management of sedentary resources require the application of non-conventional methodological tools. Understanding the fishing process, in particular, is central to the analysis and management of those fisheries. The purpose of this thesis was to investigate the fishing process and its impact on stocks of the Patagonian scallop (Zygochlamys patagonica) fishery. Data and information utilized included: (i) historical data from commercial vessels and experimental fishing; (ii) positional, catch and effort data, and additional information corresponding to fleet activity between 1995...

Estimación de los poderes de pesca relativos de la flota dealtura convencional merlucera argentina. Zona patagónica: 41°-48°S OceanDocs
Irusta, C.G.; Aubone, A.; Simonazzi, M.A.; Ibañez, P.M..
In this paper detailed mathematical description of the generalized lineal model used and data grouping criteria are presented in order to estimate the relative fishing power of four categories of the hake ice-chilled fleet. The analysis was focused to the patagonian sector (41°-48°S) of the hake total distribution area.The fleet has systematically operated in the same fishing areas between 1989-1993. The variables that better explain in yields trends of each vessel category were analyzed. The fishing power of vessels with power higher than 1200 HP has been raising since 1990 because of increasing efficiency. These vessels generate three times more fishing mortality than the standard vessels (lower than 700 HP)

Estratificación de la flota industrial de buques fresqueros y estimación de los rendimientos OceanDocs
Bertolotti, M.I.; Pagani, A.N.; Hernandez, D.R.; Buono, J.J..
In order to increase knowledge about the ice chilling fleet and to explain the relationship between structural variables and yields, a simplified model was developed. The fleet was classified in three homogeneous strata. Stratum I includes the smallest ships, with a catch composition equal to that of the large coastal fishing vessels. The stratum yields decreased in 1997 and 1998. Strata II and III have common hake as the main target of catches. Yields of those strata showed a continuous decrease as of 1994/1995. Therefore, the species was replaced by other fish originally caught by other fleets. These two last strata are more vulnerable to overfishing of traditional coastal and demersal fisheries.

Estratificación y análisis de la eficacia y la eficiencia de la flota costera de pequeña escala perteneciente a la Sociedad de Patrones Pescadores del puerto de Mar del Plata. OceanDocs
Errazti, E.; Hernandez, D.R.; Bertolotti, M.I.; Buono, J.J..
This chapter includes an economic analysis of the small scale fleet of the Mar del Plata harbour, Buenos Aires Province, Argentina. The original study was carried out at the request of the Skippers Fisheries Society to find out the relative efficacy and efficiency of homogeneous groups of associated vessels. Based on the information available, to tune the observed data, assess the relative efficacy and estimate the relative economic efficiency of the fleet, an ad hoc model was designed. Length, gross registered tonnage, engine power and number of crew members were considered and analyzed as structural variables for 1995, 1996 and 1997. No changes in variables for the period were observed so, the efficacy and efficiency analysis was carried out for the year...

Evolution et activité des principales flottilles industrielles démersales en Mauritanie depuis 1980 OceanDocs
Girardin, M..
L’évolution (1980-1987) des diverses flottes démersales de chalutiers essentiellement : congélateurs céphalopodiers, glaciers non spécialisés, glaciers spécialisés (merlu – crevettes) est décrite. Les données de débarquement, fragmentaires pour certaines pêcheries et/ou non encore exploitées en détail, concernent les années 1984, 1986 et 1987 pour les glaciers non spécialisés et, uniquement 1987 pour les autres flottilles. A partir de ces informations relatives à l’effort de pêche et aux débarquements, les tendances générales et les résultats de ces flottilles sont analysés.

Fishing fleet typology, economic dependence, and species landing profiles of the French fleets in the Bay of Biscay, 2000-2006 ArchiMer
Daures, Fabienne; Rochet, Marie-joelle; Van Iseghem, Sylvie; Trenkel, Verena.
Thirty French fleets fishing primarily in the Bay of Biscay were defined based on techno-economic input criteria: i) 18 fishing gear or gear combinations ii) the location of fishing grounds visited during a year (<12 nautical miles from coast, beyond 12 nm or both) and iii) total vessel length (<20 m for trawlers and other gears <24 m). The fleets were then characterised in terms of horse power, economic dependence on a list of nine dominant commercial species (sole, Nephrops, sea bass, hake, monkfish, anchovy, cuttlefish, sardine and squid) and their contribution to the landings of these species from the Bay of Biscay. Most fleets derived the majority of their income from one or two among the nine species. Species dependencies changed little...

Flota de altura-breve reseña de la evolución histórica y operatividad durante el período 1981/1982 OceanDocs
Bertolotti, M.I.; Cabut, D.A..
This work was carried out in order to analize the ship incorporation history to the Argentine fishery fleet and the ship building policies in Argentine shipyards and ship importations. From fresher trawler fleet and freezer trawler fleet analysis we estimated optimun catch, possible catch, and natural stock for each fleet. A modern fresher fleet might reach the present value of the optimun catch, but it would not satisfy the total inshore fish factories demand unless equitable ratio between the optimun catch capacities of the fresher trawler fleet and the freezer trawler fleet be established.

Flota pesquera Argentina. Evolucion 1960-1998 con una actualizacion al 2000. OceanDocs
Bertolotti, M.I.; Verazay, G.A.; Pagani, A.N.; Errazti, E.; Buono, J.J..
The analysis of the Argentine fishing fleet (SW Atlantic) evolution as of 1960 allows to explain the major causes of expansion, the crisis in the fisheries and the structural changes of the fleet during the 90's. Different fleet classification criteria focused on fishing capacity, fish landing composition, yields and productivity indices are described. The expansion cycles were associated to the incorporation of fishing vessels, while the 1960-1989 crisis originated in domestic and international economic crisis and changes in the strategy pattern of the fishing countries. The latter was related to overfishing of traditional coastal and demersal fisheries and to the full exploitation of resources such as squid, blue whiting and toothfish incorporated to the...

Influencia de las interacciones con el factor Año en los índices anuales de abundancia obtenidos por modelos lineales generales utilizando datos de Captura por Unidad de Esfuerzo OceanDocs
Hernandez, D.R.; Perrotta, R.G..
The problem in the definition of a relative annual abundance index using a General Linear Model is posed. The possible factors generating changes in the catch per unit effort (CPUE) are discussed and the parameterization of the model is analyzed, in particular the Sigma-restrictive parameterization. This report considers the problem caused by the presence of interactions of first order that include the factor Year in the model. It has been mathematically demonstrated that in the presence of these interactions, the index series is not proportional to the abundance annual mean of the resource. An approach of practical order to evaluate the possible effect of the interactions that include the factor Year in the index is considered using the percentage of...
