Background Striped catfish ( Pangasius hypophthalmus ) is a valuable aquaculture fish species produced primarily in Southeast Asia. In the United States, it is bred as an ornamental species. Striped catfish has high productivity and great demand in numerous countries around the world, yet little is known about its normal physiology. Objectives The objective of this study was to establish hematologic and blood chemistry RI s for healthy juvenile Striped catfish. Methods Blood samples were collected from 70 Striped catfish raised in recirculating aquaculture systems. Whole blood and plasma samples were analyzed for multiple hematologic and chemistry variables using standard techniques. Results The RI s for hematology were as follows: PCV 23.5–35.9%, MCV 106.3–156.6 fL , RBC count 1.79–2.75 × 10 6 cells/μL, thrombocytes 26,318–73,333 cells/μL, total WBC count 36,294–94,286 cells/μL, total lymphocytes 18,997–59,998 cells/μL, small lymphocytes 13,763–51,490 cells/μL, large lymphocytes 715–21,200 cells/μL, granulocytes 4504–18,291 cells/μL, and monocytes 0–7549 cells/μL. Plasma chemistry RI s were the following: ALP 32.7–74.6 U/L, AST 20.3–1235.8 U/L, sodium 135.2–147.7 mmol/L, potassium 3.3–5.0 mmol/L, chloride 120.1–133.6 mmol/L, calcium 2.7–3.6 mmol/L, magnesium 0.9–1.3 mmol/L, phosphorous 1.4–2.7 mmol/L, glucose 4.6–7.6 mmol/L, cholesterol 2.8–5.3 mmol/L, total protein 30–42 g/L, albumin 7–11 g/L, globulin 22–32 g/L, albumin:globulin ratio 0.27–0.37, creatinine 0–8 μmol/L, and osmolality 251.8–327.9 mOsm/kg. Conclusions Reference intervals reported here can help veterinarians and fish health specialists monitor the health status of Striped catfish under recirculating aquaculture conditions for research, exhibition, and production purposes.
