| 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... |

| 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... |

| 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... |

| 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. |

| This report discusses the present status of the Cameroon Fisheries regulation with respect to the United Nations Convention on the Law of the Sea (UNCLOS) and other International Conventions notably, the International Plan of Action-Illicit, Undeclared, Unregulated fishing (IPOA-IUU). It presents an overview of the fisheries resources of Cameroon analyzing fish production, management, exploitation, postharvest treatment, fish transport, commercialization and consumption. Major threats to sustainable exploitation and management are also herein discussed. Results reveal that the United Nations Convention on the Law of the Sea (UNCLOS) and other International Conventions do impose significant new commitments to the Cameroon fisheries legislation and that... |

| An overview of the available information on the commercially important squid species distributed in the Argentine Sea and adjacent zones is given. It includes the most representative characteristics to identify the species and general information on their biology, distribution and fisheries. A biological sampling designis presented, with particular emphasis on the identification of sexual maturity stages. The world market of the squid resources has considerably risen in the last decades and one of the most important fishery zones is placed in the Southwest Atlantic region (Area 41, FAO), where squid represent 25. of the total landings. Illex argentinus, sustains the second fishery in volume, with landings reaching 612.000 tonnes in 1999. Other species,... |
