The Quality of Marks Obtained under Different Regimes of Salmon Otolith Marking
The method of creating otolith marks using specific regimes of rearing water temperature, feeding and photoperiod has been described in many works (including Brothers 1984, 1985; Volk et al. 1987; Brothers 1990; Akinicheva and Rogatnykh 1997). This method allows the creation of marks during the peri...
