Research Abstract

Feeding behavior of nocturnal fish such as catfish is mediatedby not only taste but also other senses. This studies revealed endorgans, central pathways, primary center of the brain and higher pathways in the brain for the olfactory, lateral line and inner ear and visceral senses. For the taste sense, the sea catfish, Plotosus japonicus, was found to detect transient drops of ~0.05-0.10 pH unit from ambient levels that enable them to detect marine worms (polychaets), due to the worm’s respiratory activities. The morphology of the recurrent facial taste neurons and their organization in the ganglion of the sea catfish were studies and the results show that no distinct topographical relationship of the trunk and pectoral-fin branches occurs in the ganglion although the two branches somatotopically in the anterolateral and intermediate medial regions of the facial lobe, respectively.
