Abstract/ Executive Summary:

A production of 1.88-2.2 t/ha was achieved with a BCR of 2.22:1. In the on-station experiment, it was observed that nitrogenous fertilizer up to 15 kg/ha was no adverse impact on the growth and production of shrimp. A production of 900 kg/ha was achieved at a stocking density of 5 nos/m² at that rate of fertilization.

Keywords: Improved culture technique, Tiger shrimp, Farmers pond

Location: Brackishwater Station, Paikgacha, Khulna

Start Date: 01-07-2006

End Date: 30-06-2007

Program Area: Animal Health and Management

Commodity: Shrimp

Objectives:

To demonstrate modified closed culture of Penaeus monodon in farmers' pond in the Paikgacha region; and to maximize shrimp (Penaeus monodon) production through improvement of culture management.

Methodology:

Demonstration of modified closed culture technique of P. monodon in two farmers' farm and an experiment on the impact of nitrogenous fertilizer on growth and production of shrimp, P. monodon in the on-station ponds were carried out. Six experimental ponds of 0.2 ha each were treated with 3 different fertilization patterns viz., (i) Urea @ 15 kg/ha + TSP @ 15 kg/ha, (ii) Urea @ 8 kg/ha + TSP @ 15 kg/ha and (iii) Only TSP @ 15 kg/ha each with two replications. All the ponds were uniformly stocked with nursed PL of shrimp @ 3 Nos/m². The bottom of the ponds were dried and treated with lime (Quick lime:dolomite::1:1) @ 250 kg/ka. The ponds were filled with the water of Shibsa river up to 1m and then disinfected with chlorine @ 75 ppm and fertilized with urea, TSP and muriate of potash @ 25, 30 and 10 kg/ha, respectively. After ten days, required quantity of PL were stocked in each nursery of the respective pond. In the nursery, PL were fed with commercial nursery feed @ 100%, 60% and 30% of the estimated shrimp biomass in the 1st, 2nd and 3rd week, respectively.

Budget: Six lakh fifty thousand

Total Budget (Tk.) : Six lakh fifty thousand

Achievement/Findings:

The outcome of the project would be helpful to improve farm management technique of production of brackishwater shrimp and to adapt the modified closed culture system in the south-west region of Bangladesh; the interested farmers would aquired hands-on experience on the culture technique; and the overall shrimp production of the country would be surely increased to several folds through adaptation of modified closed culture in the south-west region.
