| Effects Of Pufa (Polyunsaturated Fatty Acıds) Enrıched Algae Added Dıets On Growth And Body Composıtıon Of Sea Bass (Dicentrarchus Labrax L., 1758).
In this study, effects of the PUFA (polyunsaturated fatty acids) enriched microalgae added diets on growth and body composition of Sea Bass (Dicentrarchus labrax L.,1758) were investigated.
2000 fish with mean initial weight 4,28±0,05 g were used in the feeding trials. Feeding trials were designed as each group was duplicate. Experimental fish fed two different feeds during the 2 months. Experimental feed was prepared with 10 % PUFA enriched microalgae adding to the experimental feed.
At the end of feeding trials, mean weight gain were found 16,85±0,35 g in control group and 16,26±0,21 g in experimental group respectively. It was found that there were no differences between the mean live weight gains. Feed conversion ratio were found 1,46 in control group, 1,44 in experimental group. Spesific growth rate were found 2,2 in control group, 2,3 in experimental group.
In order to see effects of the feeds on growth and body composition sampled fish from each group at the beginning and end of the feeding trials. Fatty acids composition of sampled fish were analysed. According to the results of fatty acids analysis, different type of feeds were reflected to the fish fillets. It has been found that DHA, EPA and AA levels increased in fish fish fed with microalgae added diets. In addition, Linolenic acid level in experimental group was higher than control group. DHA/EPA ratio of fish fillets was found with 1,83 in control group and 1,81 in experimental group. This results have supported the growth of sea bass fingerlings with DHA/EPA values.
All results were analysed statistically. As a result, there was no significant differences between control and experimental groups according to growth performance and body composition. This research showed that growth performance of sea bass fingerlings fed PUFA enriched microalgae added diets were supported.
