MetadataShow full item record
This report is based on the data of fish eggs and larvae samples which were collected at the 58 stations of the Vietnamese waters, it covered from latitude 7° - 21° N and longitude 103° - 112° E. The cruise was carried out from April 30 to May 29, 1999 by M/V SEAFDEC. The Standard larvae net and Bongo net were used for the surface and oblique sampling respectively and 14,507 fish eggs and 18,919 fish larvae were caught. The specimens have been identified, which comprise of 78 families, 94 genera, 94 species of fish eggs and larvae observed from this cruise. The most abundant fish eggs and larvae during the survey were Engraulidae, accounted for 8.5% total of eggs and 23.8% total of larvae. The species composition was observed to be very abundant. In each station, at least 6 families and the highest 30 families were collected during the survey. The abundance of ichthyoplankton is rather relatively high, the distribution occurred mainly in the areas of along the coastal, near estuaries and around the islands. The abundance of fish eggs concentrated higher than fish larvae. The density of distribution of fish eggs and larvae in the North sea waters concentrated the most abundant of all and of the Central sea waters was the least abundant of all. Some of families of which fish eggs and larvae have dominated which were presented.
