The proposed three year investigation is a request for a continuation of an international exchange research program between the University of Hawaii and the University of Lecca, Italy examining the comparative physiology of intestinal nutrient transport in fish of economic importance in both countries. Hawaii and Italy both have extensive fish aquacultural activities currently underway to help meet the burgeoning human need for protein. A serious problem to fish economic development is the production of an artificial diet that is nutritious and inexpensive. The requested extension of this previously highly successful research effort will use several in vitro laboratory methods to elucidate the mechanisms of sugar, amino acid, peptide, and short chain fatty acid transport in the intestines and associated diverticula from herbivorous and carnivorous fishes at the two laboratories. The novel information resulting from these physiological studies may be important in the future development of artificial diets for these respective fishes and may reduce the time necessary for each species to reach their full aquaculture potential.

建议的三年调查是一项要求， 继续国际交流研究计划， 夏威夷大学和意大利的莱卡大学 研究肠道营养的比较生理学 在这两个国家都有重要的经济价值。 夏威夷 和意大利都有广泛的鱼类养殖活动 目前正在进行，以帮助满足人类对 蛋白 渔业经济发展面临的一个严重问题是 生产营养丰富的人工饮食， 便宜. 此前，这一要求得到了高度重视。 成功研究工作将使用几个体外实验室 方法阐明糖，氨基酸，肽， 和短链脂肪酸在肠道中的运输， 食草性和食肉性鱼类的相关盲囊 两个实验室。 这些新的信息产生于 生理学研究在未来的发展中可能是重要的 为这些鱼提供人工饲料， 每个物种达到完全水产养殖所需的时间 潜力
