Abstract
The present study on comparative efficacy of selected vegetables in relation to
fish growth was tested. For this purpose four vegetable oils (sunflower oil, mustard
oil, sesame oil & soybean oil) were supplemented (@10 %) in basal diet (comprising
GOC (40%), RB (40%) wheat flour and mineral mixture (20%) having four
treatments and one control, in triplicate. An experiment was conducted in complete
randomized design and experiment was run for 60 days. Healthy fingerlings (15
tanks) of L. rohita were started in plastic tanks of 200 lit. These were fed on
experimental diet at 3 per cent of their body weight twice in day in split dose. The
growth performance and selected water quality parameters were monitored at an
interval of 15 days. The impact of vegetable oils supplication was not visible from the
recorded water quality parameters. As the values were more or less same in the
treatments groups. However the impact of oils supplanted diet was clearly evident
from the enhanced the growth rate and improved proximate composition and digestive
enzyme activity in treatments. The respective maximum value of weight gain, per cent
weight gain, SGR, GCE and PER 7.417±.136, 60.076±1.557, 0.784±.016, 0.266±.005
and 0.322 ±.003 in T5. ‘However the FCR (6.20) was highest in control. The activity
of enzymes (Amylase 4.88±.255)’ (Protease 0.289±.006) & (Lipase 3.35±.11) was
also best in T5. From the finding of present study is clear that soybean oil @ 10
obtaining maximum growth of fish use of 10 per cent supplementation in Labeo
rohita diet is recommended
