Efficacy of vermiwash in the production of live fish food organisms

Abstract:  In the present investigation, the efficacy of vermiwash was assessed for the production of live fish food organisms (zooplankton). For this purpose, studies were conducted in 56 liter static water holding using five concentration (0, 6, 8, 10 and 12 %) of vermiwash. The application of vermiwash had significant effect on water quality. As such the values of dissolved oxygen and pH slightly reduced just after the application of vermiwash. However, a subsequent increase in pH and dissolved oxygen levels were seen from 7th day onwards. On the other hand, the levels of nitrate nitrogen, orthophosphate and total bacterial population increased after the treatment and subsequently decreased in all the treatments. In general the levels of different water quality parameters remained congenial for the growth and multiplication of zooplankton. The production rate of zooplankton in vermiwash treated waters was significantly high than control. Still the highest mean production (1336 Nos/l) was recorded with 10% concentration of vermiwash. The statistical analysis of variance (ANOVA) on mean zooplankton production showed that the treatments were significantly different as compared to control. Further, the Duncan’s multiple range test showed that the plankton production was significantly (p≤0.01) different in treatments except T1&T2 and T3&T4.On the basis of results of zooplankton production, a dose of 10% vermiwash is recommended.
