The purpose of the present study was to determine the influence of three different feeding methods on the growth performance and
survival rate of European perch (Perca
fluviatilis L.)
cultivated
in recirculating system during its transition
from natural food to pelleted feed. During the
transition from natural food to formulated diet, the feed of the fish from
group A was supplemented by chopped earthworms, while that of group B - with
frozen bloodworms. The perch from group C were fed dough-like feed, obtained by
adding of liquid betaine. The final body weight of the perch from the three
groups was as follows: A- 18.99 ±5.73
g, B- 18.49 ±5.30 g and C - 18.06 ±5.14 g, as the differences
were not significant (P>0.05). Similarly, in regard to the survival rate,
the groups did not differ. The FCR in the group fed earthworms was 1.05 ±0.02
and it was lower than that of the groups receiving bloodworms and betaine in
the diet by 1.11 ±0.02 and 1.30 ±0.06 respectively. Significant influence of
the method of feeding (Р≤0.001) was found in regard to this trait.
