From: Otolith microchemistry reveals the migration patterns of the flathead grey mullet Mugil cephalus (Pisces: Mugilidae) in Korean waters

Fig. 3

Five migration patterns of Mugil cephalus inferred by the Sr:Ca ratios in the zone spanning from the otolith core to 1000 μm toward the perimeter. Data were collected from seven locations in Korean waters. The gray horizontal bar shows the critical levels for the environmental limits based on water salinity (following Chang et al. 2004). Type I, estuarine resident; type II, freshwater migrant; type III, estuarine migrant; type IV, seawater resident; type V, seawater migrant. White down-pointing triangle indicates the otolith annual ring. Distances refer to the span (in micrometer) from the otolith core the perimeter
