Various innovative fish feeds were tested for the production of koi carp in a recirculating aquaculture system, considering insect meal () as the main protein source and phytogenic additives (-turmeric and -beetroot) as antioxidants, in the spirit of sustainable aquaculture practice. The growth performance, metabolic rate (respirometry), hematological profile, blood biochemical indicators, and oxidative stress of koi carp were determined, using feeds according to the following experimental design: CF-commercial feed, IF-innovative feed based on cricket meal, BIF-innovative feed (IF) with beetroot, and TIF-innovative feed (IF) with turmeric. The TIF recorded the best growth rate. The lowest values of lipid peroxidation (MDA), standard metabolic rate (SMR), and routine metabolic rate (RMR) were registered for the IF and TIF variants. A reduction in MDA was noted, correlated to the decrease in the metabolic rate regarding SMR and RMR for the IF and TIF. An intensification in amylase was recorded in the TIF and BIF. Compared with the CF, it seems that the IF, TIF, and BIF had a beneficial effect on the koi carp by reducing cholesterol, HDL cholesterol, alanine aminotransferase, triglycerides, and urea and by increasing the concentration of calcium and growth hormone in the blood plasma.
本着可持续水产养殖实践的精神，在循环水产养殖系统中对各种创新型鱼饲料进行了锦鲤生产测试，将昆虫粉（）作为主要蛋白质来源，并将植物源添加剂（-姜黄和-甜菜根）作为抗氧化剂。根据以下实验设计，使用饲料测定锦鲤的生长性能、代谢率（呼吸测定法）、血液学指标、血液生化指标和氧化应激：CF-商业饲料，IF-基于蟋蟀粉的创新饲料，BIF-含甜菜根的创新饲料（IF），以及TIF-含姜黄的创新饲料（IF）。TIF的生长速率最佳。IF和TIF变体的脂质过氧化（MDA）、标准代谢率（SMR）和常规代谢率（RMR）值最低。注意到MDA减少，这与IF和TIF的SMR和RMR代谢率降低相关。TIF和BIF中淀粉酶有所增强。与CF相比，IF、TIF和BIF似乎通过降低胆固醇、高密度脂蛋白胆固醇、丙氨酸转氨酶、甘油三酯和尿素，并通过增加血浆中钙和生长激素的浓度，对锦鲤产生了有益影响。
