Abstract :
With an intention to integrate artisanal level
of capture based aquaculture with the sustainable
management practices of small scale fisheries an attempt
has been made through this study to collect juveniles and
sub adults of Pearl spot Etroplus suratensis from
Gopalpur creek and to stock in small cages installed in
the same waterbody to observe its growth so as to
develop a package of practices for local fishers as an
option of additional income. Three sets of cages with
three replicas of each one were fixed and sub adults of
Etroplus suratensis were stocked at the rate of 15, 20 and
25 nos per m2
for a period of 150 days. During the period
of experiment temperature fluctuated from 24.6- 31.8oC,
water pH from 8.1- 8.5, Water transparency from 14.2 –
32.9 cm, Dissolved oxygen from 5.0- 6.9 ppm, and water
salinity from 5.3- 21.3 ppt in the cage installation site.
The daily growth rate (DGR) marked a fluctuation from
0.347 to 0.593 g/day while the specific growth rate (SGR)
fluctuated from 0.48 to 0.75%. More production was
obtained from cages stocked with more stocking density
