Twelve biochemical parameters were measured in serum blood samples from rainbow trout () maintained under controlled conditions. Forty-five samples were taken every 3 months (T1-T4) over the course of one year to define baseline values. The effect of fish total weight (TW) was also evaluated. Principal component analysis showed a clear separation between T4 and T1, and T2 and T3, indicating an increase in certain biochemical parameters with weight. Linear regression analysis showed how TW significantly explained 11-67% of the variability observed for nine parameters out of 12. Pearson's correlation matrix showed a significant positive correlation ( < 0.05) between TW and albumin, alkaline phosphatase, alanine-aminotransferase, creatinine, gamma-glutamyl transferase, magnesium, phosphorus and total protein. Furthermore, significant correlations ( < 0.05) between the majority of the biochemical parameters were found, indicating that growth can influence several parameters at the same time. The present study provides several useful baseline values for assessing the health of , indicating that fish weight is an important factor for interpreting the blood biochemical profile.
在可控条件下养殖的虹鳟鱼的血清血样中测量了12种生化参数。在一年的时间里，每3个月采集45个样本（T1 - T4）以确定基线值。还评估了鱼的总重量（TW）的影响。主成分分析表明T4与T1以及T2与T3之间有明显区分，表明某些生化参数随体重增加。线性回归分析表明TW显著解释了12个参数中9个参数所观察到的变异性的11 - 67%。皮尔逊相关矩阵显示TW与白蛋白、碱性磷酸酶、丙氨酸氨基转移酶、肌酐、γ-谷氨酰转移酶、镁、磷和总蛋白之间存在显著正相关（<0.05）。此外，发现大多数生化参数之间存在显著相关性（<0.05），表明生长可同时影响多个参数。本研究为评估虹鳟鱼的健康状况提供了几个有用的基线值，表明鱼的体重是解释血液生化特征的一个重要因素。
