J. Rix G. L. Reinitz 1977 <p>1. Anesthesia of rainbow trout (<i>Salmo gairdneri</i>) with 70 ppm tricaine methanesulfonate (MS-222) for 3-9 min resulted in a linear increase in hematocrit.</p><p>2. Handling of unanesthetized trout caused a higher and more variable hematocrit reading than did exposure to MS-222 for up to 3 min.</p><p>3. The range and standard error of hematocrit readings was smallest in trout treated with MS-222 for 1 min.</p> application/pdf 10.1016/0306-4492(77)90024-7 en Elsevier Effect on tricaine methanesulfonate (MS-222) on hematocrit values in rainbow trout (<i>Salmo gairdneri</i>) article
