Use of peas in fish nutrition

Popis výsledku v původním jazyce

The aim of the study was to evaluate the effect of peas as a component in feed mixture for common carp (Cyprinus carpio). During 70-day experiment, we especially targeted to production parameters (SGR, FCR, individual increment in %, total increment in %). Standard feed mixture commonly used in fisheries, KP1 containing 18% of nitrogenous substances (Stříbrné Hory) was used as a control diet. Six experimental treatments were as follows: control, 30% peas, 60% peas, 30% peas including citric acid and phytase and 60% peas including citric acid and phytase. The addition of citric acid was 3% and phytase 500 FTU. Fish were fed twice a day with a diet corresponding to 3% of average weight of fish stock. Weighting and adjustment of feed ration took place every 14 days. Fish were measured and weighted at the end of the experiment when samples were also taken. Besides production parameters, a length-weight parameters were also determined. Results were statistically evaluated using Kruskal-Wallis test. Common carp production measured as both the production and length-weight parameters revealed better performance in acidified diets. To conclude, peas addition in suitable ratio especially in combination with citric acid positively influenced common carp production and lengthweight parameters.
