The lateral line system and its innervation in the masu salmon Oncorhynchus masou masou (Salmonidae)

The lateral line system and its innervation were examined in the masu salmon Oncorhynchus masou masou . The species has 8 cephalic canals (supraorbital, infraorbital, otic, preopercular, mandibular, postotic, supratemporal, and temporal portion of trunk), 1 trunk canal and 9 superficial neuromast gr...

Zusammenfassung:The lateral line system and its innervation were examined in the masu salmon Oncorhynchus masou masou . The species has 8 cephalic canals (supraorbital, infraorbital, otic, preopercular, mandibular, postotic, supratemporal, and temporal portion of trunk), 1 trunk canal and 9 superficial neuromast groups (rostral, nostril, preinfraorbital, postocular, cheek and supratemporal groups in the cephalic groups, and predorsal, trunk accessory and caudal fin groups in the trunk groups). The components are generally similar to those in many other teleosts, the lateral line system of O. m. masou is distinctive in having a preinfraorbital superficial neuromast group and lacking infraorbital, mandibular and opercular superficial neuromast groups. The lateral line system of O. m. masou is compared with some other species of Oncorhynchus.
