    Description: Studies on age and growth using statolith of oceanic squids, Sthenoteuthis oualaniensis collected from Western Philippines, South China Sea, Area III have been conducted from 7 April - 19 May, 1998 by MV SEAFDEC Cruise No. 50-4/1998. A total of 1,707 squids were sampled and measured onboard. 74 statoliths which consist of 53 statoliths from female specimens and 21 from male specimens were extracted and processed using statolith ageing techniques with the body mantle length range from 107 - 217 mm and 115 - 167 mm, respectively. The male is small than the female where the male does not exceed 180 mm and the female can grow up to 260 mm. There is slightly a different dimension of growth at the statolith microstructure between the male and female specimens. In the ground statolith, growth increments were examined and grouped into four growth zones distinguished mainly by the width of the increments. It was found that the male exhibit slower growth and maturation occur at the same time with the female but at smaller size. The age of the male and female ranged from 135 - 259 days and 95 - 275 days, respectively. The life span of the species was considered within one year. It was also observed that the putative microcohort of the female could be explained from the length frequency distribution of the immature and mature female and a pool data of length frequency distribution from all stations.

    Description: The vast area comprising the Indonesian archipelago means that the utilization of fishery resources has varied ways of implementation. Therefore, data collection for fishery statistical purposes has been designed considering these complex situations. An account is given of general trends in the Indonesian fishery sector, outlining the fishery policy towards 2010. The status of the national fishery statistical systems is described. For statistical purposes in Indonesia, fisheries are classified into the following sectors and sub-sectors: 1) Marine fishery -- capture/fishing, culture; and, 2) Inland fishery -- capture/fishing in open waters, culture in inland waters, brackishwater culture, freshwater pond culture, cage and pen culture, paddy-cum-fish culture. An examination is made of the problems and constraints in collecting fishery statistics, considering the 2 categories: technical or statistical; and, operational. Proposals are made for the improvement of national fishery statistical systems.

    Experiences and case studies in the implementation of data collection methods for artisanal fisheries (2021)

    Description: Details are given of experience gained during the design and implementation of data collection methods for artisanal fisheries in a number of countries under the FAO Technical Cooperation Programme, and other national and regional projects supported by UNDP and Government Cooperation Agencies. Some general approaches that have been introduced in a number of FAO member countries are illustrated and major constraints and problems that are found to be common in the design and implementation of statistical developmental activities are highlighted. It is concluded that statistically-related management tasks are performed more effectively if designated to a national fishery statistical committee or work group with responsibilities and modus operandi as regards system design, development, implementation maintenance and support. Prior to implementing a large-scale system at national level it would be advantageous to develop a prototype system in a geographically limited but representative area. Based on experiences gained from the prototype system, stepwise expansion of the system in other areas may be necessary, by first considering new methodological requirements and operational/logistical constraints.

    Description: The fisheries resources in near shore waters of Vietnam are reported to be overexploited resulting on the decrease of CPUE. It is important to develop the off-shore fisheries in Vietnam now. However information on off-shore fisheries resources in Vietnam was still very limited. This study was designed in order to supply such kind of information. The study area was in off-shore waters of Vietnam. R/V BIEN DONG (1500 Hp) with gillnet of 5 different mesh-size (73, 95, 123, 150 and 160 mm) was used for survey. The species and catch composition, distribution of promising species, relative abundance of target species were described. As a results, 98 species belonged to 32 families have been identified. Skipjack tuna was dominant (18.5 %). Distribution of relative abundance of some major species were given.
