Abstract
This study assessed the production
performance, water productivity, and economic viability of a scampi–carp–mullet
polyculture system under low-saline pond conditions (<5 ppt) as a
sustainable alternative to intensive shrimp farming in coastal India. The
experiment was conducted in earthen ponds using freshwater prawn (Macrobrachium
rosenbergii), Indian major carps (Labeo rohita, Catla catla, Cirrhinus
mrigala) and mullets (Mugil cephalus, Liza tade, Liza
parsia). Two treatments with similar management practices, including
organic fertilization and periodic liming, were evaluated. Water quality
parameters remained within optimal ranges due to low stocking density and
regular organic inputs. Scampi exhibited satisfactory growth, while carps and
parsia, tade mullet achieved higher average body weights, more compatible with
scampi. Indigenous mullets, particularly L. tade and L. parsia,
adapted well to low-saline conditions. The relative condition factor confirmed
species health and compatibility. The polyculture system enhanced water
productivity and provided favourable economic returns with reduced production
risks compared to shrimp monoculture. These findings suggest that
scampi–carp–mullet polyculture in low-saline ponds offers an environmentally
and economically viable approach for sustainable aquaculture and coastal
livelihoods in India.
