Production of tiger shrimp (Penaues monodon) in potassium supplemented Inland Saline sub-surface water.

Abstract

Potassium deficient inland saline (10 g L−1 salinity) well water was supplemented with muriate of potash to achieve 50% (57 mg L−1) and 100% (114 mg L−1) of seawater potassium concentration and used for the production of tiger shrimp (Penaeus monodon). Total mortality was observed in non-supplemented water within 6 days compared to 88.0% survival in K+100% and 85.3% survival in K+50% up to 60 days. P. monodon were subsequently cultured for 110 days in two identical 0.25-ha ponds supplied with water of 10 g L−1 and supplemented with the potassium equivalent of 35% of seawater. Survival and production were 55.8% to 64.25% and 157.70 kg (630.8 kg ha−1) to 172.75 kg (691 kg ha−1), respectively.
