Abstract
espanolSe investigaron la composicion de la dieta y las caracteristicas del tracto digestivo del chihuil Ariopsis guatemalensis en una laguna costera en el oeste de Mexico. Esta especie es consumida por habitantes locales, y ha sido utilizada como bioindicadora de contaminacion por aguas negras. El objetivo de este estudio fue determinar si los habitos alimentarios de la especie estan relacionados con las caracteristicas morfologicas macroscopicas y microscopicas del tracto digestivo. Se capturaron los especimenes en la laguna Barra de Navidad ( Jalisco, Mexico) de 2011 a 2016. De cada individuo recolectado, se midio la longitud total (LT) y se extrajeron el esofago, el estomago y el intestino para el analisis histologico y la identificacion de las entidades alimentarias en su dieta. Segun las caracteristicas macroscopicas y microscopicas del tracto digestivo y el analisis del contenido estomacal, A. guatemalensis tiene habitos carnivoros y preferencia por los peces gobidos. Los crustaceos fueron la segunda entidad alimentaria mas importante, de los cuales destacaron los cangrejos portunidos y los camarones de fango. El tamano y la posicion de la boca, la presencia de placas dentarias en el vomer, los palatinos, los premaxilares y la faringe, y la presencia de celulas caliciformes en el tracto digestivo son caracteristicas de peces que ingieren presas vivas de consistencia dura y fraccionan su alimento antes de que este pase al esofago. El intestino relativamente corto y los pliegues en la mucosa son caracteristicas de peces carnivoros.

期刊介绍:
A bilingual open-access publication, Ciencias Marinas (CM) is an international peer-reviewed journal that contains original research findings in all areas of marine science. It is published quarterly by the Autonomous University of Baja California, Mexico, and all its contents are publicly available on our journal website. Though a limited number of copies are still printed, the journal is mainly distributed in its electronic format.
CM was conceived in 1973 as part of an academic project aimed to entice local researchers to publicly disclose their findings by adopting the culture of peer-review publishing. This academic project evolved into an international journal after accepting papers from researchers in the United States and, eventually, other parts of the world. Because of the diversity in authorship, CM issues were initially published in either Spanish or English, and occasionally in both languages. It was not until 1984 when CM included both language versions of all its contents, and it then became the fully bilingual journal it still is today. At CM we believe our inclusive format allows us not only to address a wider range of submissions from international authors but also to make published findings available to a wider international audience.
So whether you are looking for information on the redfish in Icelandic waters or the physical and biological properties of the Gulf of California, feel free to peruse CM contents. You may find them to provide source material for your research.
