Regulation of sperm motility in Eastern oyster (Crassostrea virginica) spawning naturally in seawater with low salinity
Fig 8
Effect of magnesium (Mg2+) ions on sperm motility (%, A-C) and velocity (μm/s, D-F) in Eastern oyster, Crassostrea virginica. Sperm was activated in artificial seawater (ASW) or Mg2+-free ASW. Motility and velocity with each treatment (B, E) and time post-activation (C, F) is displayed. Data were analyzed using a repeated measures ANOVA and shown as mean ± SE (n = 5). Treatments with different superscripts significantly differ (p < 0.05).
