Análisis preliminar de la explotación de Gelidium robustum (Gardner) Hollenberg y Abbott en Baja California Sur, México

Gelidium robustum (Gardner) Hollenberg & Abbott is a red algae distributed from Punta Descanso, B.C. to Margarita Island, B.C.S., in production volumens and it is also economically important dueto agar-agar extraction from this species. The aim of this preliminar study was to assess explotation...
