This proposal envisages a work plan that would contribute to furthering scientific knowledge on the use of plant saponins as fish feed additives and benefit tilapia culturists not only in Israel and Palestine, but the world over. The basic research objectives include: a) extract and concentrate saponin fractions from two local edible plants, akub and fenugreek b) study the effectiveness of these saponins in inducing sex inversion or preventing reproduction in Nile tilapia in comparison with Quillaja saponins with which we have previous experience c) study the effects of these saponins on growth and feed nutrient utilization in tilapia d) gain insights into the mechanism of action of the saponins and e) use this knowledge to modify saponin structures to increase their potency. In addition, this project seeks to introduce both aquaculture research and practice to the Palestinian Authority (PA) areas aided by transfer of existing know how from the Israeli and German partners and new results from this trilateral co-operation. Direct results expected include identification of saponins or mixtures thereof, extracted from plants commercially cultivable in the Middle East, which could be used as tilapia feed additives and the introduction of tilapia aquaculture research and practise into the PA. The synergistic capabilities of the partners bode well for the successful implementation of the project.

该提案设想了一项工作计划，该计划将有助于促进关于使用植物皂苷作为鱼类饲料添加剂的科学知识，并使罗非鱼养殖者不仅在以色列和巴勒斯坦，而且在全世界受益。基本研究目标包括：A)从两种当地可食用植物中提取并浓缩皂苷；akub和胡芦巴b)研究这些皂苷在尼罗罗非鱼诱导性别反转或防止繁殖方面的有效性，并与我们之前有经验的Quillaja皂苷进行比较c)研究这些皂苷对罗非鱼生长和饲料营养利用的影响d)深入了解皂苷的作用机制e)利用这些知识修改皂苷结构以提高其效力。此外，该项目力求通过转让以色列和德国合作伙伴的现有技术以及这种三边合作的新成果，向巴勒斯坦权力机构地区介绍水产养殖研究和实践。预期的直接结果包括鉴定从中东可商业化栽培的植物中提取的皂苷或其混合物，这些皂苷可用作罗非鱼饲料添加剂，并将罗非鱼养殖研究和实践引入菲律宾。合作伙伴的协同能力预示着项目的成功实施。
