| Abstract: | The resource survey of Penaeus monodon in the northwest waters of South China Sea has been reported in this paper. The survey range is from the north of the Beibu Gulf to the waters around the Hainan Island, with water depth within 60m. As the seabed is complex, different fishing gears of trawl, trammel net, two-stick stow net and cage-type stow net have been used. The results show that the catch of Penaeus monodon distributes mostly in the waters to the east and south of the Hainan Island. The young shrimp (BL < 30mm), distributing only in the estuary of eastern and southern Hainan Island, can be seen all the year round. The quantity of young shrimP is the highest in November, and reduces then. The spawning seaso is almost through a year and the peak occurs from September to December, when the ovary matures and ovulates by stages. The spawning area is located to the east and south of the Hainan Island, with water depth between 30 and 60 meters. The diets of Penaeus monodon vary widely, mainly composed of small-sized benthos, then small-sized nekton and plankton. There is no obvious change in feeding habit. |
