Fecundity and egg size of grey-eel catfish Plotosus canius (Hamilton, 1822) from the coastal waters of Kampong Telok, Negeri Sembilan, Peninsular Malaysia

Despite the vast researches on catfish species in Malaysia, Plotosus canius, the grey- eel catfish which is primarily found throughout the coastal seas of Malaysia has been neglected. No single published work on aspects of biology, especially its reproductive biology is available. In this study, fec...
