An on-farm trial was carried out in 12 earthen ponds at the Montala Village Muktagacha Mymensingh for a period of 4 months (July-October 2003) to assess the potential of increasing pond fish production by growing dhaincha (Sesbania rostrata) in the pond bottom.

In treatment-I (T1) dhaincha without fertilizer in treatment-II (T2) dhaincha with 25 fertilizer in treatment-III dhaincha with 50 fertilizer and in treatment-IV (T4) dhaincha with 100 fertilizer were used. Dhaincha seed was sown at 100 gx40m-2 from bottom to dike. After 50 days of sowing dhaincha on the moist pond bottom lime and fertilizer were used and fish fry were released after watering the ponds.

Abstract

An on-farm trial was carried out in 12 earthen ponds at the Montala Village Muktagacha Mymensingh for a period of 4 months (July-October 2003) to assess the potential of increasing pond fish production by growing dhaincha (Sesbania rostrata) in the pond bottom. The experiment consisted of four treatments each with three replications with an object of replacement for the use of fertilizers in fish production. In treatment-I (T1) dhaincha without fertilizer in treatment-II (T2) dhaincha with 25 fertilizer in treatment-III dhaincha with 50 fertilizer and in treatment-IV (T4) dhaincha with 100 fertilizer were used. Dhaincha seed was sown at 100 gx40m-2 from bottom to dike. After 50 days of sowing dhaincha on the moist pond bottom lime and fertilizer were used and fish fry were released after watering the ponds. The stocking density of rohu (Labeo rohita) catla (Catla catla) mrigal (Cirrhinus cirrhihosus) silver carp (Hypophthalmichthys molitrix) and Thai sarputi (Puntius gonionotus) was 12 350 fishxha-1 in all treatments. Fertilization was done at 100 g urea 100 g TSPx40 m-2 50 g urea 50 g TSPx40 m-2 25 g urea 25 g TSPx40 m-2 in treatments T4 T3 and T2 respectively and no fertilization in T1. Some of the water quality parameters showed significant difference among different treatments but most parameters were found within the suitable ranges for pond fish culture. Recorded periphyton groups were composed of Bacillariophyceae (9) Chlorophyceae (10) Euglenophyceae (2) Cyanophyceae (6) Crustacea (2) and Rotifera (3). Among these groups Cyanophyceae was the most abundant in number of which Microcystis was most abundant. The mean abundance of Cyanophyceae in treatments T1 T2 T3 and T4 were 2 0997 159 cellsxcm-2 59 2597 941 cellsxcm-2 53 82712 983 cellsxcm-2 and 56 41913 015 cellsxcm-2 respectively. The mean survival rate in treatments T1 T2 T3 and T4 were 82.14 84.53 82.83 and 83.23 respectively. The highest growth rate of fish observed after one month of stocking and then growth rate was decreased gradually. Highest total net fish yield was recorded in T2 (1 619 kgxha-1) where 25 fertilizer was used along with Dhaincha followed by T1 (1 249 kgxha-1) T3 (1 421 kgxha-1) and T4 (1 268 kgxha-1). It can be concluded that use of dhaincha along with 25 fertilizer would be a better environment friendly management system for pond aquaculture than the only fertilizer dependent culture practice.
