Description Diversification of shrimp farming with marine finfish in a farmer participatory research model
was attempted. The study is intended to find an economically viable finfish culture during the
fallow period of shrimp farms. The Silver pompano, Trachinotus blochi iintercropped with
Pacific white shrimp, Litopenaeus vannamei culture in coastal shrimp ponds was assessed
for growth, survival, and economic viability. During the grow-out period of 100 days, fishes
grew from 40.23 ± 1.40 g to 256.56 ± 1.08 g in weight and 12.83 ± 0.19 cm to 25.11 ± 0.09
cm in length. The daily weight gain (DWG) and daily length gain (DLG) were 2.16 g/day
and 0.12 cm/day, respectively. Relative growth rate (RGR) and specific growth rate (SGR)
recorded for weight was 537.80% in 100 days and 1.85% per day, respectively. Pompano
has exhibited its sturdiness and adaptability to the land-based culture system as evidenced
by an overall survival percentage of 89.8% including nursery and grow-out phases. The realized
feed conversion ratio was 1.94. The culture period of 100 days is found to be enough to
attain a desirable harvest size of 250 g. The projected production potential of the experimental
demonstration farm of 4500 m2 water spread area for culture was 16.2 tonnes/cycle with
a benefit-cost ratio (BCR) of 1.34 over operational cost. The present participatory trial empirically
proved the viability of Silver pompano as an intercrop in coastal shrimp ponds. Thus,
the introduction of Pompano in shrimp ponds is recommended and can be promoted for sustainable
intercropping with shrimp farming along the Indian coast for improving people’s
livelihoods.
