Tóm tắt

Abstract:Tilapia are a commonly aquacultured fish yet little is known about their normal physiology and response to disease. In this study we determined the results of complete hematologic (n = 40) and plasma biochemical profiles (n = 63) in production tilapia (Oreochromishybrids). The fish were raised in recirculating systems with a high stocking density (120 g/L), and were in the middle of a 15‐month production cycle. Blood was analyzed using standard techniques, and reference intervals were determined using nonparametric methods. Non‐production tilapia (n = 15) from low‐density tanks (4 g/L) also were sampled; the clinical chemistry results were compared to reference intervals from the fish raised in high‐density tanks. Differences were noted in plasma protein, calcium and phosphorus concentrations, such that reference intervals for high‐density production tilapia were not applicable to fish raised under different environmental and management conditions.
