This award supports Prof. Donald Kapraun of the University of North Carolina at Wilmington in collaboration with Prof. Andres Lemus of the Universidad de Oriente, Cumana, Venezuela. The researchers intend to engage in a basic research project that will complement an applied research effort in Venezuela to commercially exploit local seaweed resources, initially by harvesting biomass from nature, and subsequently by developing the technology to raise selected seaweeds in a mariculture system. More specifically, the researchers plan to: screen selected isolates for suitability as mariculture seed stock; determine optimal conditions of light intensity, water temperature and salinity for their growth; develop techniques to vegetatively propagate cloned isolates by spheroplast isolation or fragmentation, and to seed substrate for outdoor cultivation; and initiate sexual and somatic hybridization studies to determine the feasibility of creating new genotypes. By combining techniques of genetic engineering of the U.S. side with the information from field studies of the Venezuelan side on the seasonality of growth and reproduction of certain seaweed species, the proposed research has the potential to help develop a seaweed mariculture industry for developing countries.

该奖项支持北大学的唐纳德·卡普劳恩教授 卡罗莱纳在威尔明顿与教授合作。 委内瑞拉库马纳东方大学。 研究人员 打算从事一项基础研究项目， 委内瑞拉的一项应用研究， 当地的海藻资源，最初是从 自然，随后通过开发技术来提高 在海水养殖系统中选择海藻。 更具体地说，研究人员计划： 适合作为海水养殖原种的分离物.测定 最适光照、水温、 盐度为他们的成长;发展技术， 通过原生质球分离繁殖克隆分离物，或 破碎，并用于室外栽培的种子基质;以及 启动有性和体细胞杂交研究，以确定 创造新基因型的可行性。 通过结合技术， 美国基因工程方面的信息， 委内瑞拉方面关于增长季节性的实地研究 以及某些海藻物种的繁殖， 有潜力帮助发展海藻养殖业 对于发展中国家来说。
