Abstract The present study evaluated the replacement of fishmeal (FM) by blends of alternative protein sources in diets for juvenile (8.0 ± 0.5 g) Totoaba macdonaldi. Using a FM-based control diet containing 53% crude protein and 13% crude fat, a 3 × 3 factorial experiment was conducted replacing FM, at levels of 33, 66 and 100% by weight, with three blends of the test ingredients, as follows: 1) Arthrospira meal blend: 70% Arthrospira sp. meal, 15% blood meal, 15% soy protein concentrate (SPC); 2) blood meal blend: 70% blood meal, 15% Arthrospira sp. meal, 15% SPC; and 3) SPC blend: 70% SPC, 15% blood meal, 15% Arthrospira sp. meal. At the end of the 6-week feeding trial, significant effects of the alternative protein blends were detected, in which fish fed the Arthrospira meal and SPC blends had significantly (P

使用替代的植物和动物蛋白混合物代替鱼粉，用于幼鱼 Totoaba, Totoaba macdonaldi 的饮食

摘要 本研究评估了在幼鱼 (8.0 ± 0.5 g) Totoaba macdonaldi 日粮中用替代蛋白质来源的混合物替代鱼粉 (FM)。使用含有 53% 粗蛋白和 13% 粗脂肪的基于 FM 的对照饮食，进行了 3 × 3 析因实验，以 33%、66% 和 100% 重量的水平代替 FM，用三种测试成分的混合物，如如下： 1) 节旋藻粉混合：70% 节旋藻属。膳食，15% 血粉，15% 大豆浓缩蛋白 (SPC)；2) 血粉混合物：70% 血粉，15% 节旋藻属。膳食，15% SPC；和 3) SPC 混合物：70% SPC、15% 血粉、15% 节旋藻。一顿饭。在 6 周的喂养试验结束时，检测到替代蛋白质混合物的显着影响，其中喂食节旋藻粉和 SPC 混合物的鱼有显着（P
