Acknowledgments The researchers from IPN-CICIMAR (GHC, DLAH, YERM, and JIMA), wish to express their thanks for the fellowship granted under the program of exclusivity (“Beca de exclusividad”) of the “Comisión de Operación y Fomento de Actividades Académicas del IPN (COFAA)” and also the program “Estímulo al Desempeño de los Investigadores del IPN (EDI)”. This research was supported with funds from the “Secretaría de Inves-tigación y Posgrado” of the IPN, and CONACYT. We thank the diver Fernando López for helping to collect the algae samples in Bahía Asunción, and Kim Siewers and Mike Foster for the English editing.

N2 - The brown alga Eisenia arborea is the second most abundant brown alga along the western coast of the Baja California Peninsula of Mexico. Samples of E. arborea were collected in Bahía Asunción, BCS, over 10 months. Chemical composition was analyzed from dried alga (%, dw): moisture (10.34%), protein (9.44%), ash (24.77%), lipids (0.60%), fiber (5.22%), and carbohydrates (49%). Gross energy was 9.8 kJ g-1. Seven minerals were analyzed and the four most abundant were K, Na, Mg, and Ca, ranging from 907 to 7,946 mg.100 g-1. The concentrations of six vitamin levels were also determined: A, C, E, D3, B2, and B1. Seventeen amino acids were analyzed and the most abundant were glutamic acid, aspartic acid, and leucine. Total fatty acids ranged from 21 to 65 mg.100 g-1 (dw). Individual concentrations were also determined for arachidonic acid, alpha linolenic acid, linoleic acid, eicosapentaenoic acid, and docosahexaenoic acid. Saponins, cyanogenic glycosides, and alkaloids were not detected. Our results suggest that E. arborea is a good candidate to be tested as supplement food for animals, including humans. It contains essential amino acids, is low in lipids and fiber, and could be a source of vitamins and minerals.
