This study aims to evaluate some biochemical parameters and serum electrolytes in cultured rainbow trout (Walbaum, 1792) to evaluate a potential correlation with biometric parameters (weight and length). For this purpose, 100 cultured trout (300-700 g weight range, 25-38 cm length range) bred on a fish-farm were used for the study. Physico-chemical characteristics of water were measured on the farm. Blood samples were collected from each fish to analyze the following parameters: glucose, triglycerides, cholesterol, aspartate aminotransferase (AST); alanine aminotransferase (ALT), calcium (Ca), chlorine (Cl), iron (Fe), phosphorus (P), magnesium (Mg), potassium (K), sodium (Na) and urea. Statistical data analysis showed a significant correlation between size and glucose and cholesterol. No correlation was found between size and other parameters studied. These results represent a contribution to the study of fish size leading to better understanding some biochemical parameters and serum electrolyte profiles in cultured rainbow trout. This research contributes to understanding the intra-individual variability of some blood parameters in cultured rainbow trout offering reliable information on chronic stress status, metabolic disorders and deficiencies in relation to different sizes. These could help in improve the health monitoring in trout fish farms.
本研究旨在评估养殖虹鳟（Walbaum，1792）的一些生化参数和血清电解质，以评估其与生物特征参数（体重和体长）之间的潜在相关性。为此，本研究使用了某养鱼场养殖的100条虹鳟（体重范围为300 - 700克，体长范围为25 - 38厘米）。对养殖场的水质理化特性进行了测量。从每条鱼采集血样以分析以下参数：葡萄糖、甘油三酯、胆固醇、天冬氨酸转氨酶（AST）；丙氨酸转氨酶（ALT）、钙（Ca）、氯（Cl）、铁（Fe）、磷（P）、镁（Mg）、钾（K）、钠（Na）和尿素。统计数据分析表明，鱼的大小与葡萄糖和胆固醇之间存在显著相关性。在所研究的鱼的大小与其他参数之间未发现相关性。这些结果为鱼类大小的研究做出了贡献，有助于更好地了解养殖虹鳟的一些生化参数和血清电解质谱。本研究有助于了解养殖虹鳟某些血液参数的个体内变异性，提供有关慢性应激状态、代谢紊乱以及与不同大小相关的营养缺乏的可靠信息。这些有助于改善虹鳟养殖场的健康监测。
