    Description: Zooplankton samples from 31 stations in the western Philippines water were collected by M.V. SEAFDEC on 7 April - 19 May 1998. Six major groups were identified: Euphausiacea, Natantia (Penaeidea and Caridea), Reptantia, Brachyura, Stomatopoda and cephalopod paralarvae. Three genera of Euphausiacea were found, they belong to one family: this group formed 25.1% - 90.9% of total taxonomic groups at different stations. The superfamiiy Penaeidea consisted of seven genera belong to four families. Caridea larvae were composed of 11 families including 19 genera. Retantia consisted of three infraorder: Stenopodidea, Thalassinidea and Parinuridea. The infraorder Parinuridea comprised two families: Palinulidae and Scyllaridae. Fourteen families of Brachyura larvae occurred in the study area. Stomatopoda was composed of three families including three genera. Cephalopoda paralarvae were presented in the plankton samples by six families representing eight genera. The maximum counts for malacostraca larvae and cephalopod paralarvae was observed at station 16. The present study reveals that some economic species such as Penaeus spp., Parapenaeus spp., Panulirus spp., Scyllarus spp., Portunus spp. and Sthenoteuthis oualaniensis were important components of the zooplankton assemblages in the western Philippines.

    Description: A survey on the zooplankton in the waters of western Philippines was carried out from April 18 to May 9, 1998. The estimate of zooplankton biomass ranged from 0.92 mg/m3 to 20.85 mg/m3 with a mean of 5.70 mg/m3. Maximum and minimum densities of zooplankton recorded were 4683/m3 in station 16 and 446/m3 in station 5, respectively. The zooplankton communities were comprised of 37 different categories of animal groups. Copepods were the most dominant group in zooplankton communities at all stations but their abundance varied from 5% to 43% of the total zooplankton.

    Description: The diamondback squid (Tysanoteuthis rhombus) is a potential resource popularized mainly for the export market in the Central Philippines and the positive results from other experimental activities. Exploratory fishing for the species using the giant squid jig was conducted on board MV SEAFDEC and MV Maya-Maya in the South China Sea (Western Philippines) to determine its occurrence, abundance and distribution in these areas. The gear employed is basically used in small boats hence, its operation on bigger vessels was very difficult. The result was discouraging with only one diamondback squid caught out of the 175 jigs set. The description and fishing operations of the gear are presented with comparison from other research and fishing results conducted in Camotes Sea, Calauag Bay, and Ormoc Bay which are considered potential areas.

    Description: Many schools of small bonito were observed at latitude 18°-19° N, longitude 118°-119° E, school of pompano dolphinfish Corphaena equiselis (Linnaeus, 1758) was also found and sampling during lured by light at night. Surface schooling of yellowfin tuna Thunnus albacares Bonnaterre, 1788) skipjack, Katsuwonus pelamis (Linnaeus, 1758) were found at latitude 14°-15° N and longitude 117°-118° E. Many fish schools were observed through acoustic equipment, Furuno FQ-70 at near shore of Zambales and off shore at latitude 13°-14° N, longitude 117°-118° E, in the deep layer of 100-250 meters depth. Oceanic squid has widely distribution over the area. Fishing activities are target on those resources. Tuna longline fishing operation was observed at latitude 16°-17° N and longitude 116°-117°E about 150 nautical miles away from shore. Payaws were set along the coastal line from northern Luzon until northern of Palawan and from near shore until 30-80 nautical miles away from coastline. Payaw in the central part were aimed for purse seine operation while the northern Payaw aimed to handline fishing. Handline fishing occupied all most near shore area from northern to the south. Squid fishing was observed many near San Fernando.

    Description: Several species of oceanic squids are believed to occur in the South China Sea, especially off the west coast of the Philippines. Sthenoteuthis oualaniensis was one of the species that dominated the catch during the research survey off western Philippines in April to May 1998. Preliminary study was carried out on some biological features of Sthenoteuthis oualaniensis, particularly on maturity pattern, sex ratio and stomach content. There was a similarity in maturity pattern throughout the study areas with the same proportion of mature and immature squids. In all stations, the female squids outnumbered the male and the size of the female was general bigger than the male squids. ML50% of female was estimated to be at 175 mm while range of mature female was between 110 - 240 mm. Fish and cephalopods were the most frequently occurring prey taxa found in the diet of Sthenoteuthis oualaniensis, contributing between 37% - 46% and 30% - 43% respectively. Identification of prey taxa especially to species level was strictly limited, due to lack of proper references and understanding of the nature of fish species composition within the study areas. Results discussed in this paper may serve as early information for future biological study on S. oualaniensis.

    Description: Composition, abundance and distribution of ichthyoplankton were investigated in the South China Sea, western Philippines. Larval fish samples were collected at 31 stations by surface and double oblique tows in April/May 1998. A total of 7371.67 fish larvae, representing 85 families, were collected in the samples. Abundance of fish larvae were dominated by the Myctophidae followed by the Gonostomatidae. The ten most abundant families of fish larvae found in this study were separated into three broad categories: (1) inshore fishes, represented mainly by the Bregmacerotidae, Gobiidae, Apogonidae, and Carangidae;(2) mid zone fishes represented mainly by the Hemiramphidae, Labridae and Engraulidae;(3) offshore fishes represented mainly by the Myctophidae and Gonostomatidae. Depth and time of day appeared to affect the abundance of fish larvae and fish eggs. Fish larvae were found mainly in double oblique tows while fish eggs were found mostly in surface tows. The larvae caught at night were more abundant than larvae caught during the day. Abundance and distribution of tuna larvae are also discussed.

    Description: The need to improve fisheries information management in the region was recognized as early as 1982 when SEAFDEC, in collaboration with IDRC, organized the Seminar on Fisheries Information Science in Southeast Asia. During the Seminar, existing fisheries information systems at the national, international, and regional levels were identified, and corresponding problems and constraints were discussed. The recommendation to strengthen the national information services and to promote regional cooperation/collaboration with a view to improving effective transfer of fishery information within and outside the region was considered. As a sequel to the 1982 Seminar, the SEAFDEC Secretariat organized the SEAFIS Regional Seminar on Fishery and Aquaculture Information Systems in Southeast Asia, held in Bangkok, Thailand, from 7 to 10 February 1989. The list of participants and observers, and the Agenda appear as Annexes 1 and 2. The objectives of the Seminar were to review the current status of fishery and aquaculture information systems in the region, and to determine future activities in order to strengthen collaboration between various information sources in Southeast Asia. The Seminar also aimed to determine the appropriate training programs which could enhance development of fishery information systems in the region as well as improve information management.

    Description: Work was undertaken on fish taxonomy of marine fish found in Vietnamese waters in order to revise the “Field guide to important commercial marine fishes of the South China Sea”. Two field surveys were carried out at 9 separate locations from April 23 to May 17, and 2 other locations from September 20-26, 1999. A total of 442 specimens of fish from 107 different families were collected and photographed. Among the 442 specimens, 336 specimens were successfully identified to the species level, 99 specimens to the genus level, and only 7 specimens to the family level. The sampling areas at Qui Nhon, Nha Trang and Phan Thiet provided the most number of samples of 96, 94 and 79 fish, respectively. A total of 348 fish were new candidates for the Field Guide. More field surveys are necessary to cover the rather extensive array of new fish specimens expected to be found in these waters.

    Description: A collaborative acoustic survey between the Research Institute of Marine Products (RIMP), Vietnam and the Marine Fishery Resources Development and Management Department (MFRDMD) of SEAFDEC, was carried out in Vietnam waters from April, 29 to May, 29 1999. Survey was conducted by using the scientific echo sounder, FQ70 installed on board of MV SEAFDEC. Survey transects were designed perpendicular to the coastline with standard length of 60 nautical miles. The vessel was cruised at 10 knot and stopped at each station for oceanographical sampling. During cruising, the back scattering strength, SV were collected and saved in multiple storage media. SV values were verified during data analyses by removing any noise and scattering layers. The back scattering values by area (SA) is calculated and the fish density by transects are produced. Using those parameters, the biomass of pelagic is estimated based on representative species from the sampling program and national fisheries statistics. Pelagic biomass in Vietnamese waters was estimated at 9.26 x 106 tonnes with the average density of 15.93 tonnes/km2. This estimation is based on dominance species of Decapterus maruadsi.
