Production of Penaeus monodon in the tide fed ponds of Sunderbans

Abstract

Penaeus monodon was cultured in two tide-fed ponds (0.162 ha and 0.184 ha) of
Sunderbans, at Kakdwip, India, giving special emphasis to water quality management
for sustainable production of shrimp. For first 60 days, filtered and
treated tidal water and later untreated water was used for exchange. Water
temperature, dissolved oxygen and pH were monitored twice daily, turbidity
once in a day. TSS, total alkalinity, salinity, COD and BOD were estimated at
weekly intervals. Water exchange was done when turbidity and dissolved oxygen
were around 20 cm. and 4mg /1 respectively. During culture, liming @ 75 kg
/ ha and fertilizers, N and P @ 0.2 PPM each were used for correction of D.O and
turbidity problems. During 100 days culture, at a stocking density of 6.7 / sq.m
and 7.1 /sq.m, 58.26 % and 58.08 % of stocked seed survived and produced 196
kg and 217 kg of biomass with FCR of 1.150 and 1.173 respectively.
