Conventional fish feed based on fish meal, meat, and soy cake presents procurement difficulties and high costs, affecting the profitability and sustainability of the aquaculture industry.
To evaluate the effect of hydrolyzed red worm (HRW- ) in red tilapia ( ) diet on production parameters.
The study was conducted at the aquaculture farm of the Politécnico Colombiano Jaime Isaza Cadavid (PCJIC) at 780 m.a.s.l.,with an average temperature of 28 °C. Ninety red tilapia fingerlings, averaging 7,5±0,5 g, were distributed in nine aquariums containing 75 liters of water. Fish underwentweight and size measurements at the beginning and end of the trial. They were fed experimental diets to apparent satiation three times daily. Water quality parameters and productive rates of growth and nutrient utilization were measured. The experimental design included three treatments with three replicates each: T1 (control diet, 0% hydrolysate inclusion), T2 (10% hydrolysate inclusion), and T3 (20% hydrolysate inclusion). ANOVA (p<0,05) was applied to growth and nutrient utilization variables, with mean comparisons using α<0,05 in SPSS version 25.
Significant differences (p<0,04) were found between the control diet T1 (0% inclusion) and T2 (10% inclusion) in favor of weight gain (31,87 g). There were no statistical differences in size increase (p<0,217). As HRWinclusion increased, feed consumption decreased, likely due to higher hydrolyzed protein availability. Feed conversion rates showed significant differences (p<0,001) between T2 and T3 compared to T1, indicating better assimilation of the hydrolyzed protein. T2 and T3 also showed better protein and energy efficiency (p<0,001), demonstrating the hydrolyzed protein's nutritional quality and assimilation. Diet cost decreased with higher hydrolyzed inclusion (p<0,034).
Inclusion 10% and 20% hydrolyzed red worms significantly improved production parameters and reduced costs, making it a viable alternative for feeding red tilapia for small and medium-scale producers.
基于鱼粉、肉类和豆饼的传统鱼饲料存在采购困难和成本高昂的问题，影响了水产养殖业的盈利能力和可持续性。
评估水解红虫（HRW- ）在红罗非鱼（ ）日粮中对生产参数的影响。
该研究在海拔780米、平均温度28°C的哥伦比亚理工大学海梅·伊萨扎·卡达维德分校（PCJIC）的水产养殖场进行。90尾平均体重7.5±0.5克的红罗非鱼幼鱼被分布在9个装有75升水的水族箱中。在试验开始和结束时对鱼进行体重和体长测量。每天三次投喂实验饲料至明显饱足。测量水质参数以及生长和养分利用的生产率。实验设计包括三个处理组，每组三个重复：T1（对照日粮，水解产物添加量0%），T2（水解产物添加量10%），T3（水解产物添加量20%）。对生长和养分利用变量应用方差分析（p<0.05），在SPSS 25版本中使用α<0.05进行均值比较。
对照日粮T1（添加量0%）和T2（添加量10%）之间在体重增加方面存在显著差异（p<0.04），T2组体重增加更有利（31.87克）。体长增加方面无统计学差异（p<0.217）。随着HRW添加量增加，饲料消耗减少，这可能是由于水解蛋白的可利用性更高。与T1相比，T2和T3之间的饲料转化率存在显著差异（p<0.001），表明水解蛋白的同化效果更好。T2和T3在蛋白质和能量效率方面也表现更好（p<0.001），证明了水解蛋白的营养质量和同化效果。随着水解产物添加量增加，日粮成本降低（p<0.034）。
添加10%和20%的水解红虫显著改善了生产参数并降低了成本，使其成为中小型生产者喂养红罗非鱼的可行替代方案。
