Giant freshwater prawn (Macrobrachium rosenbergii De Man), the symbolic resources of Songkhla Lake, one of the most abundance species has been declined due to the changing of the environment caused by the upstreaming of salt water into Talay Laung. However, from the year 1989 until now, the increasing amount of rainfall and surface runoff help reducing the salinity in the lake and has brought up the total number of prawn-catched each year. During the last survey in May 1994, prawn catched from the lake was approximated 1,000 kg/day. This is the highest yield of prawn-catched in decade since it is not a season for catching which usually begin in October until January.
