| We contend there are currently two competing scenarios for the sustainable development of shrimp aquaculture in coastal areas of Southeast Asia. First, a landscape approach, where farming techniques for small-scale producers are integrated into intertidal areas in a way that the ecological functions of mangroves are maintained and shrimp farming diseases are controlled. Second, a closed system approach, where problems of disease and effluent are eliminated in closed recirculation ponds behind the intertidal zone controlled by industrial-scale producers. We use these scenarios as two ends of a spectrum of possible interactions at a range of scales between the ecological, social, and political dynamics that underlie the threat to the resilience of mangrove... |

| Property rights are important institutions for regulating the use of valuable natural resources from coastal ecosystems. In this case study, we identify and analyze property rights and user patterns related to small-scale coastal fisheries in the Stockholm Archipelago, Sweden. User patterns and user groups have changed significantly over the last century, as commercial fishing has been increasingly replaced by recreational activities. Interviews with local resource users and owners of water properties in two different areas, Möja and Ornö parishes within the Stockholm Archipelago, revealed a very diverse pattern of property and user rights, with a large number of water and fishing rights owners. Recreational fisheries, including both... |

| Coastal fisheries and marine cultures developed under strong biological, economical and social constraints. Among others are limitation of space and resources, limited availibility of capital, hardship of work,... Industrial, urbanistic and touristic development add to these constraints in coastal areas. Coherent scheme for coastal fisheries management, capture and culture, is of an urgent need. In renewable resources and environnement economics, depletion and pollution resulting from common ownership have been the core of the theory about fisheries management. The chronology of Japanese coastal fisheries management system shows a different approach. In law and decision making, social and economic consequences of conflictual uses and of their regulation... |

| A dedicated trawling experiment was performed at three sites on the Gulf of Lion continental shelf, with the aim of assessing the resuspension of particulate and dissolved matter triggered by different types of trawls on muddy sediments. The different configurations were: (i) bottom trawl, with bobbin for ground rope (Rockhopper): (ii) bottom trawl, without bobbin (Medits); and (iii) pelagic trawl, towed at 1 and 10m above the seabed. The plumes of resuspended sediment were measured using the acoustic backscattered intensity, from a towed ADCP. Concomitant profiles of particle size-distribution, light transmission and water samples were collected, outside and inside the plumes. The analysis of the data enabled derivation of the major physical and... |

| The maritime fisheries and mariculture guidance law passed in 1997 specifies that with the perspective of renegotiation of the common fisheries policy in 2002, a report on the special conditions of inshore fisheries be drawn up by the Government. To do so, the Minister of Agriculture and Fisheries entrusted this task to three experts, who are the authors of this report. In accordance with their remit, the situation of fisheries in territorial waters and estuaries of metropolitan France and the four DOM overseas departments ( counties) was examined, in the framework of meetings with professional fishermen, administrations, elected officials and scientific organisations. The first part situates fishing activities in coastal areas within the overall context... |

| Argentine black drum distributes mainly in shallow waters associated to estuarine areas, particularly to Samborombon Bay where it may be detected throughout the year. Nevertheless, it can also be spotted more southwards (40°S) and at deeper waters. During summer, catches of the species in Samborombon Bay are practically negligible, probably due to movements towards shallow waters out of reach of the inshore commercial fleet. Landings increase in autumn and show peak values in winter, coinciding with the fishing season of whitemouth croaker, Micropogonias furnieri, whose geographical distribution within the bay overlaps that of black drum. As of 1995, landings of black drum showed increasing trends both in Argentina and Uruguay. These increments coincide... |

| 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,... |

| Patagonian smoothhound (Mustelus schmitti) is one of the predominant cartilaginous fishes of the Argentine Sea (SW Atlantic Ocean). It is caught, mainly, in the coastal multispecific fishery with nearly other 30 bony and cartilaginous species. The group is known as ‘variado costero’. In this work the smoothhound abundance indices (CPUE) and standardized efforts for the 1992-2008 period in the area between 34~’S-42~’S were estimated. The General Lineal Model (GLM) and data derived from the argentine commercial fleet were used. Other aspects that could affect estimates and trends of the annual indices were also analyzed. Mean CPUE values estimated with the GLM, considered as annual standardized abundance indices, show an increasing trend as of 2000; the... |

| Monte Hermoso (Province of Buenos Aires, Argentina) is a tourist town inhabited by a large number of artisanal fishermen. The aim of this study was to characterize, through a descriptive analysis, the operational activity of the artisanal fleet and quantify the catches landed per species. The ships, of a trucker type, are 6-9 m length equipped with a 40-90 HP outboard motor. The data analyzed derive from purchase slips furnished by a gatherer corresponding to the November 2009-October 2010 period. The target species were stripped weakfish (Cynoscion guatucupa) and patagonian smoothhound (Mustelus schmitti). The former was caught with hand line throughout the year, essentially between September-December. The latter was fished during March-April and... |

| The diversity and relative species abundance of fisheries resources were studied from Winneba to Cape Coast on the central coast of Ghana during December 2007 to May 2009. Samples of organisms were collected at random from beach seine landings during the study period. The fishes were counted and identified to the family and species levels. Ecological indices such as Shannon-Wiener diversity index, equitability and Sørenson’s similarity index were used to analyse the data. Specimens from Winneba, Saltpond and Cape Coast comprise 56 species belonging to 30 families. Carangidae, Haemulidae, Clupeidae and Sciaenidae were some of the families, where key species occurred during the study. The relative abundance of key organisms in the beach seine landings... |

| Whitemouth croaker Micropogonias furnieri fishery during three intensive fishing seasons in the outer area of the La Plata River (Argentina-Uruguay) is analyzed. Resource exploitation in the South Atlantic area shows a general retraction of the distribution range and an isolation of the La Plata River stock where most of the fishing effort concentrates. The species market evolution brought about, for Argentina and Uruguay, an important shift in its dynamics as of 1992, when the product insertion in Asiatic markets generated an important commercial attraction and a subsequent increase in the fishing effort by the argentine inshore coastal fleet. This caused a change in the fishery development in Argentina and the establishment, in winter, of a fleet... |

| The study aims to discriminate juvenile and adult concentration areas of white croacker Micropogonias furnieri and striped weakfish Cynoscion striatus in two different areas: Argentine-Uruguayan Common Fishing Zone (AUCFZ) and El Rincón (Buenos Aires Prov., Argentina). The length structure and the relative abundance of these two species were analyzed with data from a research cruise carried out by R/V Dr.E.L.Holmberg during November 1994. Data of relative abundance in t/nm2 were considered to define distribution and concentration areas. 49 samples of white croaker and 41 striped weakfish from AUCFZ a, inside the area of Río de la Plata and in front of Montevideo coast, at depths lesser than 8 meters, while the adults were located in the northern coast of... |

| Stripped weakfish is one of the ensemble of species known as “variado costero” most frequently landed. Considering that fact, determination of abundance indices is particularly relevant to apply assessment models and make recommendations to allow for a proper fishery management. The aim of this study was to obtain those indices of the species derived from research cruises carried out in the Argentine-Uruguayan Common Fishing Zone AUCFZ area (34°S-39°S) in the 1993-2006 period. In order to improve the traditional estimate accuracy modeling was used. To formulate the general linear models year, stratum, length, bottom salinity, depth factors and population data such as mean size and juveniles percentage were used. The percentages of variance explained in the... |
