Hematology of Striped Bass in Fresh Water

Abstract
Eight hematological characteristics were measured on a total of 40 adult striped bass (Morone saxatilis) taken during four collections from three freshwater reservoirs. The range of mena hematological values from the four samples was as follows: hematocrit 31-38%, hemoglobin 7-11 g/100 mL, plasmaosmolality 321-381 mOs, plasma chloride 129-156 meq/L, plasma glucose 77-118 mg/100 mL, plasma cortisol 0.77 -6.33 µg/100 mL, total plasma protein 4.3 -4.9 g/100 mL, and total plasma cholesterol 322-499 mg/100 mL. These means generally fell within the range of means reported for apparently healthy striped bass from salt water. The variability within our samples was comparable to the variability associated with same measurements or fish held under controlled laboratory conditions. We attribute this to the rapid collection and preparation technique we employed in the field. No consistent pattern in the differences between collections was discerned and they may be attributed to normal variations due to seaso...
