Özet
In this study, experiments were carried out to evaluate the blue mussel ( Mytilus edulis ) trochophore as a potential live feed for marine fish larvae. A short-term low temperature storage method has been developed to preserve and transport live trochophores. The mean size of M. edulis trochophores was found to be 73,50 ± 5,24 m m . The survival rates of trochophores were ascertained in 4-5 ºC storage condition. Blue mussel fatty acid profile showed a predominance of 16: 0 (14,17%) and 20: 5 ( w -3) (20,01%), and high concentrations of 16: 1 ( w -7) (7,79%) and 22: 6 ( w -3) (6,14%). Concentrations of 20: 5 ( w -3) and 22: 6 ( w -3) totaled 26, 15%. Total w 3-HUFA accounted for 36,14% of the total fatty acids. The study suggested that mussel trochophores would be a good diet for marine fish larvae due to the size, suitable fatty acid composition, storage time up to 6-7 days and also capability to swim at low temperatures.
