The dietary algae at different juvenile stages of Anodonta woodiana
摘要
Abstract
The composition and variation of dietary algae were studied with swan mussels Anodonta woodiana at dif-ferent juvenile (1.5-month-old, 2.5-month-old and 6-month-old) stages. The results showed that Cyanophyta and Chlorophyta were the major components. The number of dietary algal species in the mussels tended to increase over the juvenile stages (i, e., 11 species at 1.5-month-old, 13 species at 2.5-month-old, and 37 species at 6-month-old). The dominant algal species in 1.5-month-old juveniles were Chroococcus minutus, Chlorella vulgaris and Tetraëdro mini-mum, while those in 2.5-month-old juveniles were C. vulgaris, T. minimum, and Merismopedia glauca. Besides C. vul-garis and M. glauca, some large algae (e.g., Scenedesmus quadricanda) could be found in the dominant algae species of 6-month-old juveniles. The quantity of T. minimum was significantly different between the fore-intestine and hind-intestine in 6-month-old juveniles (P<0.05), reflecting a possibly high bioavailability. The aforementioned results provide important scientific basis to break the dietary algae“bottleneck”for ongoing establishment of the standardized culture A. woodiana population, and also for the artificial culture and resource enhancement of other freshwater mussels.关键词
