Understanding how social resilience influences resource users&amp;#8217; responses to policy change is  important for ensuring the sustainability of social&amp;#8211;ecological systems and resource-dependent communities. We use the conceptualization and operationalization of social resilience proposed by Marshall and Marshall (2007) to investigate how resilience level influenced commercial fishers&amp;#8217; perceptions about and adaptation to the 2004 rezoning of the Great Barrier Reef Marine Park. We conducted face-to-face interviews with 114 commercial and charter fishers to measure their social resilience level and their responses and adaptation strategies to the 2004 zoning plan. Fishers with higher resilience were more likely to believe that the...

An economic survey of the commercial operators currently active in the Queensland Coral Reef Fin-Fish Fishery has been carried out, as part of a research project aimed at evaluating alternative management options for this fishery. This paper presents the background analysis used as a basis to develop the sampling design for this survey. The background analysis focuses on activity patterns of the fleet based on effort and catch information, as well as patterns of quota ownership. Based on this information, a fishing business profile describing the micro-economic structure of fishing operations is developed. This profile, in conjunction with the qualitative information gained in undertaking the economic surveys, allows preliminary understanding of the key...

La flotte de pêche commerciale bretonne
Provedor de dados: 5
Autores: Talidec, Catherine; Berthou, Patrick; Jezequel, Michele; Lespagnol, Patrick.
The annual activity calendars of the 2,000 Breton fishing boats registered in the national POP file (with the exception of seafaring ships: 35 ocean-going tuna boats and 2 ships from Saint-Malo) were reconstituted for the year 1994 through surveys of the owners of these ships. Resorting to this method was necessary to overcome the weak statistical coverage of coastal fishing activity that is practiced within the 12 miles of territorial waters. This collection of information made it possible to build a database that contains, for each boat, the various trades practiced during the year 1994 and, if applicable, the periods of inactivity. By "trade", we mean the putting to use of a fishing vessel in order to catch one or several target species, in a given...

Autores: Dato, C.V.; Villarino, M.F.; Cañete, G.R.
Discards of the commercial fleet in the Argentine Sea (SW Atlantic) directed to hake Merluccius hubbsi were estimated in weight and number of individuals. The dynamics of the ice-chilling and freezer fleets per area and quarter and processes of discarding were analyzed. The estimation method was based on the comparison of landings and surveys length composition, the latter filtered by the selectivity of the mesh used by the commercial fleet to rebuild the length distribution of catches. It is concluded that discards had an annual variation of 42,000 t-148,000 t in the 1990-1997 period, which represented between 30 and 50 in weight and 11-24 in number of actual catches. The analysis of age groups affected by discards showed that over 90 corresponded to...

Whitemouth croaker (Micropogonias furnieri)has a broad distribution along the Atlantic coast of the Americas, from Mexico to the south of the Province of Buenos Aires, Argentina. At the southern end of distribution, Argentina and Uruguay catch the species with different commercial fleet types bay or creek, coastal and off-shore and modalities of bottom trawling with doors and paired trawling. Maximum catches of both countries, that reached 60,000 t, were registered between 1995 and 1997. After that period a remarkable decrease was observed, specially in Argentina where catches remained at around 6,000 t over a total of 30,000 t for both countries. The commercial fleet was divided in three categories and the total area of study in three subareas: El Salado,...

Both mackerel mean biomass and mean fishing effort in Buenos Aires (Argentina) shelf during the period 1990-91/1994-95 were estimated. Those values were 85,792 t and 42,051 minutes, respectively. However, the best economic profit from the fishery (about $15,390,036)($1=U$S1) was estimated to take place at 28,000 minutes. It was observed a waste in fishing effort of the commercial fleet related with sea surface temperatures of 19°C or more. Moreover, adult mackerel find better trophic conditions on the continental shelf (depth 50m), while larvae originated from massive spawning in late November-early December, i.e., during the main fishing season, find their optimum at lower depths. Mackerel shoals enter and leave fishing grounds in a counterclockwise way...

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...

The chub mackerel Scomber japonicus and anchovy Engraulis anchoita commercial landings at the Mar del Plata (Buenos Aires prov., Argentina) seaport during the September 1999-January 2000 period are studied. A total of 14 chub mackerel samples were taken for total length measurements exclusively and 5 anchovy sub-samples and 1 chub mackerel sub-sample were analyzed to record individual data total length, weight, sex, sexual stage, age from otoliths readings . Most of the fish caught for both species were adults and only a small fraction of chub mackerel juveniles was found in December 1999. Length-at-fifty-percent-maturity was calculated, length-weight and length-age relationships were fitted and length growth parameters estimated. Sea surface temperature...

Autores: Dato, C.V.; Villarino, M.F.; Cañete, G.R.
To improve the quality of the resource assessment it is necessary to estimate discards and quantify them applying an adequate methodology. The purpose of this work is to detect areas where the activity of the commercial fleet coincides with zones of high concentration of juveniles because they are potential discard areas. To establish possible seasonal and/or interannual variations, length distribution data derived from hake research surveys carried out on board of INIDEP vessels during the 1986-1993 period were analyzed. Samples were grouped per statistical rectangle on the basis of catch weighted average and mean, variance, skewness and kurtosis were calculated. The resulting parameters were subjected to a cluster analysis using the Euclidean distance...

Beneficio económico de la caballa (Scomber japonicus) con relación a la temperatura superficial del mar en el área de Mar del Plata.
Provedor de dados: 20
Autores: Perrotta, R.G.; Hernandez, D.R.
The temperature that limits the presence of schools of Argentine chub mackerel Scomber japonicus was found to be around 19°C in the Mar del Plata area Buenos Aires prov., Argentina. At higher values, most shoals leave coastal waters in direction to the mid-shelf. An inverse relationship was observed between catches per unit of effort CPUE and sea surface temperature. The highest CPUE values corresponded to temperatures lower than 19°C. Beyond that value, the possibility of obtaining a CPUE higher than the unit is nearly null and the low standard deviation means it is unlikely to reach high CPUE values. The economic profit per minute of each daily cruise was estimated using a case study carried out with a single vessel pilot with mean structural and...

Based on the comparison between length composition of landings and that of research cruises, filtered by the selectivity of the mesh used by the commercial fleet, to rebuild length distribution of catches, an indirect quantitative method was developed and used to estimate, in weight and number, the individuals discarded by the commercial fleet south of 41° S. Discards ranged between 15,563 and 46,113 annual tons in the 1986-1993 period which represented 10-13% in weight and 28-32% in number of actual catches, composed of around 87% of individuals age group 1, 12% of age group 2 and the rest of individuals age groups 0 and 3.

Patagonian scallop (Zygochlamys patagonica King Broderip, 1832): A new fishery in the Argentine continental shelf. We present preliminary information on a new fishery of patagonian scallop (Zygochlamys patagonica King Broderip, 1832) in the Argentine Continental Shelf. A research program was conducted jointly by INIDEP and a fishing company during 1995 with the F/V Erin Bruce. The vessel, fishing equipment and processing on board are described. A total of 7235 fishing tows were performed during 246 days at sea. Seven new beds were located between 38º 50' S and 42º 30' S, along the 100-m isobath. Beds are discrete. Differences in the size structure by bed suggest that recruitment consists of sporadic pulses. Proportion of scallops and invertebrate by-catch...

Mise en oeuvre de mesures de conservation et gestion durables des ressources halieutiques : le cas du Sénégal
Provedor de dados: 20
La pêche occupe une place importante dans l’économie et la société sénégalaises. En effet, elle est une activité multifonctionnelle qui contribue à la fois à l’équilibre de la balance des paiements du Sénégal, à la résorption du chômage et à la satisfaction des besoins alimentaires de la population sénégalaise. Malgré son importance, le secteur de la pêche est confronté à de graves déséquilibres socio-économiques et environnementaux qui résultent de la surexploitation des ressources halieutiques et de l’utilisation de certains modes d’exploitation néfastes. Il en découle des difficultés d’approvisionnement des marchés locaux et une diminution de l’apport en protéine des populations tributaires de la pêche. En outre, la forte propension à l’exportation de...

Una investigación del manipuleo, distribución y mercadeo de pescado fresco y congelado del sector artesanal en el Ecuador
Provedor de dados: 20
Autores: Wood, C.D; Boustead, P.; Mora, Y.; Grijalva, M.
En los últimos años han habido evidencias del aumento de exportaciones por vía aérea de pescado fresco. Los desembarques artesanales se destacan en este aumento, particularmente de dorado, y el incremento de las exportaciones estimula también alguna diversificación de productos. Una mayor limitación a más exportaciones se entiende de la competencia para espacio restringible de flete aéreo entre los exportadores de productos perecederos (pescado, flores, frutas, etc.), y de la necesidad de coordinar el reparto y la extensión de la capacidad de carga. Las actividades de pesca y comercialización están muy fragmentadas, y resultó que esta industria compleja era dificil de controlar. Esta es la razón para estudios de este tipo, para actualizar y ampliar la...

Fishing activities with trawl nets used by the commercial fleet in the continental slope of the Southwest Atlantic are quite different from those developed in the Argentine shelf because, in the former, depths are very variable and slopes are more marked: therefore, fishing procedures are quite different. In this work, the most important differences are described: fish species, fishing gear, type of vessel and machinery on deck, as well as the training and experience of skippers.

Autores: Leta, H.R.
Los calamares dada su particular abundancia son 105 moluscos marinos de mayor importancia de las aguas uruguayas. Entre éstos, el calamar Illex argentinus es el recurso más importante del área. Si bien la tecnología de captura aplicada no es específica para el recurso, los volúmenes capturados con red de arrastre principalmente para merluza, por las unidades de la Flota Comercial de Altura Uruguaya, indican la existencia de una importante biomasa de estos cefalópodos. Estas consideraciones sumadas al fácil acceso a la zona de explotación y a la duración de la temporada de pesca, favorecen el establecimiento de una pesquería propia del recurso. En 1980, el programa de investigaciones de INAPE incluyó el estudio integral de la explotación de los calamares...

Dinámica de la flota comercial argentina dirigida a la pesquería de merluza (Merluccius hubbsi) en el Mar Argentino. Periodo 1990-1997
Provedor de dados: 20
Autores: Dato, C.V.; Villarino, M.F.; Cañete, G.R.
Since 1990, the Argentine commercial fleet directed to hake (Merluccius hubbsi) has obtained more than 70 of catches South of 41°S while to the North of this latitude the activity concentrated between 39°S and 41°S Argentine Sea, SW Atlantic. Bearing in mind the different characteristics of ice-chilling and freezer fleets, their activities were analyzed separately. Considering the relative percentages of catches declared in fishery statistics, the dynamics of each fleet is described per quarter and year. Special reference is made to 1997 when a closed area to protect juveniles was introduced between 44°S-47°S and 62°W-65°W. The freezer fleet activity, concentrated South of 41°S, especially South of 43°S, was stable throughout the period. It grouped around...

Autores: Garciarena, A.D.
Data obtained by observers on board of two fishing vessels during six trips carried out between January-April 2010 to catch tuna were analyzed. Thirty-four fishing days were completed and of the 59 trawls performed 37 turned out positive (with tuna catches). The fishing gear consisted of a purse seine net. Exploitation took place within the Argentine-Uruguayan Common Fishing Zone, between 36° S-39° S. The main landings occurred in March and consisted of slender tuna, Allothunnus fallai (57%), followed by albacore, Thunnus alalunga (28.5%), in January and bonito, Sarda sarda (14%), in April. Sea surface temperature ranged 16 °C-19 °C. A total of 25 length frequency samples allowed to measure individuals of the species above mentioned and those of skipjack...

Autores: Ruarte, C.O.; Perrotta, R.G.
The stripped weakfish (Cynoscion guatucupa) has a wide latitudinal distribution (22° S-43° S) and it is object of fishery in Brazil, Uruguay and Argentina (SW Atlantic). In this last country, it is mainly captured in the coastal region of Buenos Aires Province by means of a fleet, which has between 20 m and 30 m length. In Argentina, the average landings in the last 5 years were 9,900 t. It is the second commercial species among the coastal groups. There are two main fishery areas of this species: the Argentinean-Uruguayan Common Fishing Zone (AUCFZ) and the El Rincón area, in the South of bonaerense littoral. Due to the importance of this species, it is necessary to define an index of annual abundance to allow a suitable diagnosis of the fishery...

Efectos del filtrado de datos sobre la estimación de la tendencia de los índices de abundancia de polaca (Micromesistius australis)
Provedor de dados: 20
Autores: Cordo, H.D.
Catch per unit of effort (CPUE)analysis of the Argentine surimi fleet is a routine work to estimate abundance indices of southern blue whiting Micromesistius australis. Several analysis of this fishery suggest that, as of the years when intensive fishing by foreign and national fleets started, the resource has suffered a marked decline. When calculating the CPUE it is common practice to take into acount only trips and fishing operations with high catches of the target species fishing operations directed to other species are not considered to avoid underestimations. Therefore, in order to include a percentage of catch of the analyzed species higher than a subjective value, available data are filtered. However, because only operations with high yield are...

Autores: Chavance, P.
En 1987, 59 chalutiers pélagiques (62-102 m, 2000 – 3880 cv) ont opéré dans la ZEE mauritanienne. Trois pays sont représentés : l’URSS, la Roumanie et l’Allemagne de l’Est. Les captures totales atteignent 441473 tonnes dont 66,5% est pêchée par les soviétiques, 26,3% par les roumains et 7,2% par les allemands de l’Est. Les chinchards (&lt;Trachirus sp et Decapterus rhonchus&gt;) prédominent dans les captures avec 50,8%, les sardinelles en représentent 14,9% et la sardine 7,7%. L’activité des flottilles est apparue, comme  en 1986, très marquée par les saisons hydrologiques.

Autores: Perrotta, R.G.; Garciarena, A.D.; Hernandez, D.R.
Chub mackerel caught by the commercial fleet in El Rincón (39°-41° 30’ S) and Mar del Plata (38° S) areas was analyzed. In 2001 and 2002 samples from El Rincón were obtained from landings or collected by scientific observers on board the commercial ships. Samples from Mar del Plata were acquired during the 2001-2002 and 2002-2003 fishing seasons, on board two vessels of the small purse-seine fleet. Landings were mostly adults and only a small fraction of juveniles was observed (&lt; 5%). Length growth parameters from El Rincón samples were estimated, and length-weight and length-age relationships were fitted by Least Squares. The results were as follows: L(mm) = 538.4; k (years-1) = 0.122; t0 (years) = -4.92; Pt = 4*10-7 * Lt 3.536. Natural mortality was...

Autores: Irusta, G.; Pérez, M.; Renzi, M.A.; Castrucci, R.
The activity of fishing fleets for hake Merluccius hubbsi south of 41°S Argentine Sea, SW Atlantic, is described. In order to establish the standard group of vessels, density indices derived from research cruises and ice-chilling fleets were related. Group four 1,400-1,800 HP related better to the abundance trend. Also, two series of indices associated to different fractions of the population were estimated: juveniles  age 2) and adults age 3-5. Finally, a total catch per unit effort CPUE for the region south of 41°S, which showed a declining trend during the period considered 1991-1997, was calculated.

Circuits de distribution - commercialisation du poisson dans le sous secteur de la pêche artisanale en Mauritanie
Provedor de dados: 20
Autores: Moussa, A; Nguer, A.T.; Thiam, I.
Résumé : Les résultats obtenus dans le cadre de ce travail ont permis de montrer que le produit de la pêche artisanale en Mauritanie est surtout commercialisé en frais. La transformation des produits est faite selon deux principales méthodes, le guédj (fermenté - séché) et le salé séché. Au niveau de la distribution – commercialisation, il existe deux types de circuits : les circuits courts (distribution plage – ville) et les circuits longs (distribution entre les villes). Il est à noter que la commercialisation est handicapée par le mauvais état des routes, le coût exorbitant du transport et le manque de moyens de conservation du produit frais.

Autores: Cordo, H.D.
Ling (Genypterus blacodes) resource was assessed by means of an age structured production model fitted with stock abundance indices from catch per unit effort data (CPUE) obtained from the commercial fishing fleet. Reproductive stock was assessed in the same way with CPUE data from the fishery research vessel. A short-term analysis of collapse risk as a function of 1999 and 2000 fishing mortalities was carried out with the results, and also a long-term analysis with the assumption of a variable fishing mortality (F) with two recruitment hypotheses. Results show that the present state of the Ling resource has worsened with respect to the last assessment. Considering the best of all cases, the Br/Kr relationship decreased from 0.55 to 0.33, indicating that...

La pêche industrielle des espèces pélagiques côtières en Mauritanie de 1979 à 1985 - Deuxième partie : la Pêche au chalut pélagique
Provedor de dados: 20
Autores: Josse, E.
Après la mise en place de la ZEE à 200 miles en 1978, la pêche au chalut pélagique s’est développée très rapidement en Mauritanie. Avec un effort de pêche pratiquement multiplié par 10 entre 1979 et 1983. De 1979 à 1986, sept pays ont participé plus ou moins régulièrement à l’exploitation des ressources pélagiques côtières de la ZEE mauritanienne, avec des chalutiers pélagiques de gros tonnage. Trois pays : l’Allemagne de l’Est, la Roumanie et l’URSS ont réalisé, selon les années, entre les ¾ et la totalité de l’effort total, et de 80 à 100% des captures totales. Les captures totales ont été maximales en 1983, avec 470 000 tonnes. Après une baisse en 1984 elles se sont stabilisées en 1985 et 1986 entre 450 000 et 460 000 tonnes. La composition spécifique...
