Fermented water hyacinth meal has potential as a substitute for soybean
flour in striped catfish feed. The purpose of the study was to analyze the
physiological response and growth of striped catfish fed a feed containing
fermented water hyacinth. The research was carried out from August to October
2020 at the Riau University reservoir. The method in this study was an experiment
using a one-factor completely randomized design (CRD) with five treatment levels
and three replications. The treatment in this study was substitution of soybean
meal by water hyacinth meal at doses of 0%, 25%, 50%, 75%, and 100%. The fish
used weighing 4.2 ± 0.6 g were stocked in fixed-net cage units with a density of 1
fish/28 L (25 fish/cage unit) for 42 days. Feeding was carried out 2 times a day, at
07.00 and 17.00 WIB with a dose of 5% biomass. Fish weight measurement was
carried out every 14 days, blood hematology observations of digestive enzyme
activity and intestinal histology were carried out at the end of rearing.
The results showed that feeding containing fermented water hyacinth had a
significant effect on the physiological condition of striped catfish and did not
significantly affect the growth of striped catfish. P2 is the best dose in the feed
striped catfish based on the activity of the enzyme cellulase, protease, and lipase
0,029 respectively; 0.025; and 0.070 units/ml, specific growth rate 4.14±0.1
%/day, feed conversion 0.95±0.1, total erythrocytes 191±33.1 x 104 cells/mm3,
hematocrit 34±5, 6%, hemoglobin 6.33±0.6 g/dL, total leukocytes 105.7±309.4 x
103 cells/ mm3, intestinal histology showed normal symptoms with an average
number of goblet cells 7±0.6 cells/field of view, and 100% survival rate. The
average value of water quality, namely temperature 28.85 0C, dissolved oxygen
6.55 mg/L and pH 6.24 were in the optimum range for the growth of striped
catfish.
