Effects of water temperature, dissolved oxygen and total suspended solids on juvenile barbonymus schwanenfeldii (Bleeker, 1854) and Oreochromis Niloticus (Linnaeus, 1758)
The aim of the present study was to investigate the effects of water temperature, dissolved oxygen (DO), and total suspended solids (TSS) in water on an indigenous fish species, Barbonymus schwanenfeldii (Bleeker, 1854), and an exotic fish species, Oreochromis niloticus (Linnaeus, 1758) in Malaysia....
