论文摘要
为了支持未来几年的水产养殖产量的预期增加，需要更广泛的鱼粉替代成分，以促进生产可持续性的提高。这项研究旨在测试用Gilthead Seabream（Sparus aurata）生长性能，饲料利用率，营养素的明显消化率和对环境的营养产量的明显消化率测试饮食。制定了四种异义源和同工饮食：类似于商业饲料的对照饮食（CTRL），以及三种实验饮食，其中包括主要蛋白质源，植物副产品，麸质和浓缩液（植物）；加工动物蛋白（PAP）；或微/大藻，昆虫粉和酵母（紧急）。饮食在80天内一式三份测试。与其他治疗相比，（新兴）治疗导致鱼类生长的性能较低，FCR较高，养分和能量保留较低。对于紧急饮食，发现蛋白质的最低消化率是导致氮损失增加的。与CTRL治疗相比，植物和子宫颈瘤处理可提高鱼类生长的性能，更高的养分和能量保留率以及更低的FCR。鱼喂养植物和子宫颈豆饮食的FCR的显着改善以及这些饮食的高蛋白质消化率有助于最大程度地减少Seabream生产的环境影响
To support the expected increase in aquaculture production during the next years, a wider range of alternative ingredients to fishmeal is needed, towards contributing to an increase in production sustainability. This study aimed to test diets formulated with non-conventional feed ingredients on gilthead seabream (Sparus aurata) growth performance, feed utilization, apparent digestibility of nutrients and nutrient outputs to the environment. Four isonitrogenous and isoenergetic diets were formulated: a control diet (CTRL) similar to a commercial feed and three experimental diets containing, as main protein sources, plant by-products, glutens and concentrates (PLANT); processed animal proteins (PAP); or micro/macroalgae, insect meals and yeast (EMERG). Diets were tested in triplicate during 80 days. The (EMERG) treatment resulted in lower fish growth performance, higher FCR and lower nutrient and energy retentions than the other treatments. The lowest protein digestibility was found for the EMERG diet, which caused increased nitrogen losses. The PLANT and PAP treatments resulted in better fish growth performance, higher nutrient and energy retentions, and lower FCR than the CTRL treatment. The significant improvement in FCR found for fish fed PLANT and PAP diets and the high protein digestibility of these diets contribute towards minimizing the environmental impacts of seabream production
