EFFECT OF WATER HYACINTH COMPOST IN NURSERY REARING OF FRINGE LIPPED CARP, LABEO FIMBRIATUS (BLOCH, 1795)Raghavendra, C.H., Kiran Dube, Sridhar, N., Raghunath, M.R., Chandra Prakash, Dam Roy, S. and Gangadhar BarlayaAbstract The impact of the application of compost obtained from water hyacinth (Eichhornia crassipes) on spawn of fringe lipped carp Labeo fimbriatus was assessed in terms of growth and survival, in comparison to the inorganic fertilizer manured cisterns and untreated cisterns. Application of water hyacinth compost led to statistically significant improvement in the growth, as well as significant increase in survival. Weight increment and survival percentage of post-larvae in different treatments were highly significant (P < 0.01) among the treated groups. In group T-1, the average increment in growth in terms of weight was 111.4% more than group T-3 when compared to group T-2, where it was only 36.41% of group T-3 (control). With respect to survival, 517.60% increase in the survival was observed in the cisterns manured with water hyacinth compost, whereas the increase was about only 375.18% in the cisterns applied with only urea (inorganic fertilizers), when compared with the control without any fertilizer application. The present study would help in advocating the use of water hyacinth compost for better nursery practices in fish culture.
