Immersion during egg swelling results in rapid uptake of stable isotope markers in salmonid otoliths
Determining the value of restocking wild fisheries with hatchery-reared fish requires the ability to identify and quantify the survival of hatchery fish after release. However, to obtain accurate estimates of survival rates, multiple fish identification techniques are often used, making the monitori...
