| L’engraissement du thon rouge a connu un regain d’intérêt depuis le boom économique japonais i.e. vers le milieu des années 70. A cette époque les projections ont mis en évidence que la production mondiale ne suffirait plus à satisfaire le marché japonais. C’est ce constat qui a amené les grandes firmes japonaises à réfléchir sur l’engraissement du thon rouge. Cette technologie fût exportée en Espagne où l’activité a démarré effectivement au début des années 1990 pour atteindre son apogée vers les années 1996-1997. Plusieurs pays méditerranéens ont suivi le pas de l’Espagne à l’image de la Croatie, Malte, Chypre, Italie, etc., En Tunisie, pendant les six dernières années (2003-2008) l’activité d’engraissement du thon rouge (BFT) a atteint voire dépassé... |

| From 1986 to 1991, observers on board tuna purse-seiners based in Seychelles allow analysis of data such as oceanographic parameters, aspects of tuna schools and their associated sightings, as well as fishing characteristics (success rate, catches, cpue, species composition, duration of fishing sets). Performances of the four concerned countries (France, Spain, Japan, USSR) are compared. |

| The catches made by purse seiners on schools associated with logs constitute more than half of the total catch of the purse-seine fishery of the western Indian Ocean. In the purse-seine fishery on log-associated schools of tuna, either natural logs are spotted by vessels and are marked with radio beacons, or artificial logs are set at sea to concentrate the tuna prior to fishing operations. The first attempt at commercial purse seining was successfully carried out in the Indian Ocean in 1979 by a joint-venture Mauritian vessel using the same technique as the Japanese, who had traditionally fished on schools associated with logs in the Pacific Ocean. They started fishing in the Indian Ocean after experimental purse-seine fishing was conducted by the Japan... |

| The Spanish purse seine fleet operates in a wide area of the Indian Ocean since 1984. A logbooks system provides detailed information of catches (set by set) and effort. Together with this information, an intensive work of interview during 4 years (1994-1997) has provided technical equipment data. These data have been used to estimate standardized catch per unit effort (CPUE) indices of abundance for yellowfin from the Indian Ocean. Standardized catch rates have been estimated using the Generalized Linear Model (GLM) approach. The model proposed includes factors related with the stock abundance together with factors related with catchability changes. |

| Data used to generate the tables and figures presented here are based on daily catch and effort forms (logbooks) returned from fishing vessels that are licensed to fish in the Seychelles EEZ and from data collected via the tuna sampling programme conducted during transhipment in port Victoria. Sometimes there is a delay in these being received at SFA, especially during and just after the second quarter of the year when most vessels are fishing in the Mozambique Channel. Readers should note that many of the figures presented here are subject to revision (usually upwards) as more data become available. The date upon which the SFA database was closed prior to the generation of the statistical tables is shown at the head of each table. |

| This paper presents a review of the tuna fishery within the 200-mile Fisheries Conservation and Management Zone (FCMZ) of the British Indian Ocean Territory (BIOT) (Chagos Archipelago), over the period 1991 to 1995. Particular emphasis is placed on the most recent fishing seasons 1993-1994 and 1994-1995. Fishing inside the BIOT FCMZ has been dominated by distant-water fishing nations. Longliners from Japan, Korea and Taiwan have fished in the area around the Chagos Archipelago for many years. Purseseine vessels have operated in the area since the early 1980s. Some records of driftnetting also exist prior to the ban on driftnetting in 1992. The tuna fishery inside the zone is highly seasonal and highly variable. Longline vessels typically operate during two... |

| This document contains summary statistics of the NEI4 purse seiner fleet fishing in the Indian Ocean, as well as some information about how the data are collected. The sampling scheme, the sampling coverage, maps and diagrams representing the fishing pattern of this fleet by time and area strata. Data collection and the sampling programme for this fleet are the same as those used for the Spanish and French purse seine fleets. |

| The difficulties associated with tropical tuna sampling strategies, particularly those resulting from the large-scale adoption of the method of fishing on logs, have caused the Indian Ocean tuna scientists concern since the beginning of the purse seine fishery, as well as the ICCAT SCRS (Standing Committee for Research and Statistics of the International Commission for the Conservation of Atlantic Tunas) in recent years. Upon the recommendation of this Committee, in 1996 Spain and France embarked on a European Union project aiming to study the consequences of this new fishing tactic on the estimated catch by species and by size, and to implement a new sampling strategy so as to improve the accuracy of the statistics. Many specific analyses have been... |
