Fish Spawning

I went back to my hometown a couple of years back and witnessed the phenomenon of massive number of fish swimming upstream to spawn. This is quite similar to the unusual sight of salmon ,which many of us have seen in the TV documentary, migrating upstreams in North American rivers to spawn. Every year during the rainy month of October, this remarkable phenomenon occurs along Sungai Rui. Many locals are seen by the riverside, catching the fish with nets. I have seen one local filled up one gunny sacks within 2 hours. According to locals, this phenomenon has been happening for as long as they can remember. The local authority has even organised competition with winners based on the total weight of the catch.
