Turkish Towel Chondracanthus exasperates and taurine were added to alternative plant‐based feeds for juvenile sablefish Anoplopoma fimbria to evaluate the effect of these ingredients, alone or combined, on fish growth, feed intake and efficiency, whole body nutrient composition, and liver histomorphology. Fish growth was significantly increased with the addition of taurine, and to a lesser extent, Turkish Towel to the experimental feeds. Feed efficiency and protein retention were significantly improved with the addition of taurine, but were unaffected by Turkish Towel addition. As expected, whole body taurine content was significantly affected by taurine addition. Increases in whole body lipid were observed with both taurine and Turkish Towel addition, with a significant interaction between the two factors. Liver histomorphology was generally normal; however, histopathologic changes were observed in some fish at the end of the experiment. The occurrence of hepatocellular nuclear pleomorphism and clear cell foci was less among fish that had received the Turkish Towel feeds. The addition of taurine had no effect on the number of fish with a histopathologic change. Overall, results from this study reaffirm taurine supplementation is beneficial to sablefish receiving plant‐based feeds and indicate Turkish Towel may be a promising feed ingredient for this species.

添加红色大型藻类土耳其毛巾软骨鱼会激怒和牛磺酸，可提高替代性植物性饲料的性能，以替代幼体雪貂鱼类Anoplopoma fimbria

土耳其毛巾软骨鱼精和牛磺酸被添加到替代性的基于植物的饲料中，用于少年雪貂Anoplopoma fimbria评估这些成分（单独或组合）对鱼类生长，饲料摄入量和效率，全身营养成分以及肝脏组织形态的影响。在实验饲料中添加牛磺酸和少量添加土耳其毛巾后，鱼的生长显着增加。添加牛磺酸可显着提高饲料效率和蛋白质保留能力，但不受土耳其毛巾添加的影响。不出所料，添加牛磺酸会显着影响全身牛磺酸的含量。牛磺酸和土耳其毛巾的加入均导致体内脂质增加，这两个因素之间存在显着的相互作用。肝组织形态一般正常。然而，在实验结束时观察到一些鱼类的组织病理学变化。在接受土耳其毛巾饲料的鱼类中，肝细胞核多态性和透明细胞灶的发生率较低。牛磺酸的添加对组织病理学变化的鱼类数量没有影响。总体而言，这项研究的结果再次证实了牛磺酸的补充对接受植物性饲料的紫花鱼有益，并表明土耳其毛巾可能是该物种的有前途的饲料成分。
