Sargassum on Beaches in Cozumel

 

Information on this important yet stinky natural phenomenon…..

 

Some of Cozumel’s beaches are experiencing the phenomenon of a Sargassum seaweed deposit. Although it might smell less than pleasant, it’s not environmentally harmful, and fact, this natural occurance has quite a variety of benefits.

Sargassum can grow in deep water open oceans to create “floating islands” that have been chartered as several acres wide and up to 2 meters in depth!   While it’s not unusual for sargassum to wash ashore on Cozumel, it can appear unsightly, and frankly it has an off-putting odor, however thankfully the amount that has arrived this season has been of an average amount, unlike last year’s record breaking deposits.

 

It’s been speculated by scientists that this particular bout originated off the coast of South America and then was pushed toward our area by strong ocean currents.  Some even speculate that sargassum, with it’s asexual reproduction, could be considered the largest organism world-wide.  When a part of a sargassum island drifts off it continues to reproduce until it becomes less buoyant, too weighty or ends up on a beach in Quintana Roo Mexico.

Sargassum, which derives its name from the Sargasso sea where it originated, may look bad, and even smell bad, the brown algae, does offer a surprising number of benefits.  Also known as Gulfweed, is free-floating ecosystem that provides shelter, and a home for many forms of marine life.  It’s considered to be a nursery for several types of fish, including Mahi Mahi.

Sargarssum been shown to prevent sand erosion and preserve beaches.Left on it’s own, sargassum breaks down in a very short time, grinds up, and becomes incorporated into the sand.  It also has a very high nutrient content and can be used as a natural fertilizer.

Sargassum is also completely edible.  It’s slightly bitter flavor doesn’t make it nearly desirable as the more popular northern Pacific and Atlantic seaweed varieties.   Eat the Weeds offers some helpful information on cooking and eating the pungent sea vegetable.

Called Hai Zao in traditional Chinese Medicine, ground dried sargassum, and was a mainstay in the treatment of goiters, dropsies of all kinds and even menstrual disorders.

Visitors to the island might not even notice an increase in the seaweed on our island’s beaches, however, sargassum can play an important role in the ecological system, as both an erosion deterrent, or even perhaps a food source.

Sargazo en las playas de Cozumel

Información acerca de este importante fenómeno, a pesar de ser hediondo. . . .

Algunas de las playas de Cozumel están pasando por el fenómeno de depósito de sargazo. A pesar de que su olor es menos que agradable, no daña al medio ambiente y, de hecho, es un fenómeno que tiene una amplia variedad de beneficios.

 

El sargazo puede desarrollarse en mar abierto creando “islas flotantes”, ¡que han llegado a medir varias hectáreas de ancho y hasta 2 metros de profundidad! A pesar de no ser extraño que el sargazo llegue a las playas de Cozumel,  puede parecer desagradable y, francamente, expide un olor fétido; sin embargo, la cantidad en esta temporada ha sido promedio, a diferencia de los depósitos sin precedentes del año anterior.

 

Los científicos han especulado que este brote se originó en las costas de Sudamérica y fuertes corrientes marinas lo empujaron hacia nuestra zona. Algunos incluso han llegado a especular que el sargazo, con su reproducción asexual, podría considerarse el organismo más grande a nivel mundial. Cuando una parte de la isla hecha de sargazo queda a la deriva, continúa reproduciéndose hasta tiene menos flotabilidad, con mucho peso o termina en una playa en Quintana Roo, México.

 

A pesar de tener apariencia y olor desagradables el alga color café del sargazo, cuyo nombre deriva del Mar de los Sargazos donde se originó, ofrece una sorprendente cantidad de beneficios. Este ecosistema flotante brinda abrigo y es el hogar de múltiples formas de vida marina. Se considera criadero de diversas especies de peces incluyendo el dorado.

 

El sargazo ha mostrado que previene la erosión de la arena y que conserva las playas. Al dejarle solo, el sargazo se descompone en muy corto tiempo, se tritura e integra a la arena. También tiene un elevado contenido de nutrientes y puede usarse como fertilizante natural.

 

El sargazo es totalmente comestible. Su sabor ligeramente amaro no le hace tan deseable como las otras variedades de sargazo del norte tanto del Pacífico como del Atlántico.  Eat the Weeds ofrece información útil para cocinar y comer este vegetal marino de sabor agrio.

 

En la medicina tradicional china el sargazo seco y molido es conocido como “Hai Zao” y fue un elemento fundamental para el tratamiento del bocio, hidropesías de toda clase e incluso trastornos menstruales.

 

Es posible que quienes visitan nuestra Isla ni siquiera se percaten del aumento del sargazo en las playas de la Isla; sin embargo, el sargazo puede jugar un papel importante en el sistema ecológico como elemento para disuadir la erosión o incluso hasta como fuente alimenticia.
