Abstract

The present study examined the effect of fertilizer addition on water quality and loach (Misgurnus anguillicaudatus) fry growth in outdoor ponds for the promotion of loach culture in rice paddy fields. Three ponds received the following treatments: fertilizer with no loach (6-1), fertilizer with loach (6-4), and no fertilizer and no loach (6-2). Concentration of NH4+-N and PO43--P were highest in ponds that received fertilizer. Chl. a concentration was two times higher in ponds 6-1 and -4 than in pond 6-2. Furthermore, Chl. a concentration in pond 6-4 was 78% lower than that in pond 6-1. The density of diatoms and green algae was two times higher in ponds 6-1 and -4 than in pond 6-2, and the average density of diatoms was lower in pond 6-4 than in pond 6-1. Loach cultured with fertilizer in this study were slightly longer than the Chinese loach cultured in an indoor fiber-reinforced plastic tank.
