ຂໍ້ສັງເກດ | Favors deep pools and runs of mainstreams, also impounded waters; young occur in smaller tributaries. Breeds in summer, congregating in deep pools below waterfalls and rapids. Feeds on insects and invertebrates as well as algae and detritus mainly off the bottom, leaving characteristic pockets in sand and gravel beds. Decline in population is due to the introduction of bass, increasing habitat destruction and the impedence of large dams. |
