MATERIALS & METHODS
AnimalsThe research was carried out on 9816 fish (aged 1+) divided into two groups with 4908 fish in each pool for a period of 150 days.
PeriodThe experimental fish group O-I was fed with pellets which contained 1% zeolite and with simultaneously implement of “Ambizel-V” in the water of the experimental pool.
- Speed of fish growth
- Final weight (p < 0,01)
- Final length measures (p < 0,05)
- Growth increase (p < 0,01)
Based on obtained research results it can be concluded that zeolite “Ambizel-V” proved itself as reliable corrector of environmental conditions in experimental pool, because it led to slight decrease of numerical values of: total water hardness (8,54o dH); nitrate (1,22 mg/l); ammonia NH3 (0.0 mg/l).
