在夏威夷群岛，海藻和海草是绿色海龟Che lonia mydas Linnaeus的食物。16种大型藻类（7绿藻门，2褐藻门，7红藻门），两个海草物种，和多个特定的藻类草坪从海龟觅食区在四个不同的岛屿进行了分析，近（蛋白质，脂肪，碳水化合物），水，灰分，能量，氨基酸，维生素和矿物质含量。Pterocla diella capillacea（gmelin）Santelices和hommersand，一个突出的膳食项目，和Rhizoclonium implexum（迪尔温）Kutzing，一个不常食用的物种，总蛋白质含量最高。大多数物种含有< 10%的粗脂肪。可溶性碳水化合物占干重的3.2%-39.9%。灰分值范围为13.7%-81.4%干重。菌丝体的能量含量在14 kJ g-1以上。所有测试的物种都含有可测量数量的11种矿物质。维生素A（β-胡萝卜素）在所有测试的海洋植物中被检测到;大多数含有烟酸（B 3）;并且弯曲浒苔（wulfen）J. Agardh具有最高量的维生素C（3 mg g-1）。样品含有可测量量的所有必需氨基酸，除了色氨酸。这些数据提供了夏威夷绿色海龟饲养生态学和可能影响体细胞生长率的因素的新信息。
In the hawaiian Islands, seaweeds and seagrasses are eaten by green turtles, Che lonia mydas Linnaeus. Sixteen macroalgal species (7 Chlorophyta, 2 phaeophyta, 7 Rhodophyta), two seagrass species, and multi-specific algal turf from turtle foraging areas on four different islands were analyzed for proximate (protein, lipid, carbo hydrate), water, ash, energy, amino acid, vitamin, and mineral content. Pterocla diella capillacea (gmelin) Santelices and hommersand, a prominent dietary item, and Rhizoclonium implexum (dillwyn) Kutzing, an infrequently consumed species, ranked highest in total protein content. Most species contained < 10% crude lipid. Soluble carbohydrates ranged from 3.2%–39.9% dry weight. Ash values ranged from 13.7%–81.4% dry weight. Energy content of P. capillacea was over 14 kJ g –1 ash-free dry weight. All species tested contained measurable quantities of 11 minerals. Vita min A (β-carotene) was detected in all marine plants tested; most contained Niacin (B 3 ); and enteromorpha flexuosa (w ulfen) J. Agardh had the highest amount of vi tamin C (3 mg g –1 ). Samples contained measurable amounts of all essential amino acids, except for tryptophan. These data provide new information about hawaiian green turtle feeding ecology and factors that may influence somatic growth rates.
