In this study, we experimented the effects of starvation on survival performance and weight loss of exotic ornamental fishes of Bangladesh in aerated and non-aerated aquaria under laboratory condition. For this aim, a total of 14 fish species were experimented under 13 genera, 09 families and 4 orders. It was set up under two treatments for each experiment. In each experimental treatment, three fishes of a same species were released and treated as replication in determining the survival performance. Fish weight loss and water quality were also measured. Comparatively higher survival performance was found in Pterophyllum scalare (T1, 836±4.32 hours and T2, 1022±4.02 hours) while lower was recorded for Hypostomus plecostomus (T1, 116±2.44 hours and T2, 160±3.87 hours). Weight loss varied from 0.05±0.01 g (Danio rerio, Poecilia reticulata, Poecilia sphenops and Gymnocorymbus ternetzi) to 0.33±0.09g (Trichogaster trichopterus). Water temperature, dissolved oxygen, free CO2, pH, total alkalinity, ammonia-nitrogen and chlorine level were found to be varied from 25.66±0.17 to 28.66±0.35 °C, 3.80±0.06 to 4.73±0.07 mg/l, 9.21±0.05 to 11.75±0.03 mg/l, 7.13±0.05 to 7.47±0.07, 76.66±1.64 to 108.92±3.20 mg/l, 0.0010±0.0006 to 0.0133±0.002 mg/l and 0.0045±0.001 to 0.012±0.0014 mg/l respectively among different treatments of experiments. This research showed that aeration system can create healthier environment for fish than that of the without aeration one. The research findings can be helpful during feeding management for upholding good husbandry of fishes and also during transportation.Pages: 59-64 | 854 Views 11 DownloadsDownload Full Article:
