Abstract


In this paper, we approached a research theme regarding the effects of Sea-buckthorn (Hippophae rhamnoides L.) upon the growth and development of the common carp (Cyprinus carpio) in aquarium conditions. In this sense, there were organized 3 lots, each lot containing 25 individuals, weighting between 7.27 and 16.01 g. Feeding occurred with granulated feed, having a protein level of 26 %, the only difference between the lots was represented by the percentage of the added Sea-buckthorn, which was in the first case 1% and in the second one 2%, compared to the control lot, without Sea-buckthorn. During the 120 days of this experiment, we monitorised the dynamic of the body weight, accumulation of body mass, average daily gain and the survival rate. The fish breeding was carried out in aquariums, each with a total capacity of 500 l, and controlled medial conditions the only difference between the lots was the addition of Sea-buckthorn regarding the feed system.
The results obtained during this experiment, prove the opportunity and the actuality of this research theme, and the positive impact of the Sea-buckthorn upon the growth of the common carp. We need to mention the fact, that the best results were achieved in case of the supplementation of the feed with 1% Sea-buckthorn powder compared to the other two lots.
