Otolith morphology and body size relationships of Monopterus albus in Malaysia

Monopterus albus production in Malaysia is widely depends on wild stock. Otolith morphology has been widely used to give additional information that is crucial for aiding the seed production. Otolith morphology of Asian swamp eel, Monopterus albus and its relationships to fish size was examined....
