Population Biology Of The Greenback Grey Mullet, Chelon Subviridis (Valenciennes, 1836) In Merbok Estuary, Kedah

The present research investigated population biology of the greenback grey mullet, C. subviridis in Merbok estuary for one year period from November 2010 to November 2011. This study is divided into four major components: (i) mullet fish identification using morphometric and meristic; (ii) length-we...
