Attention to Strandings and Rescues

 

INFORMATION ABOUT STRANDING

A stranding consists of an event in which a marine mammal (or more than one) reaches land, dead or alive, or is in shallow water, being unable to return to deeper waters for itself.

Why do they strand?

*Diseases

* Disorientation near the coast

* Influence of man

(fisheries, noise, sonars)

* Persecution by predators

* Other factors

 

Types of strandings

-Living: of the cases we have attended to, around 40% are living individuals. In most of the cases, the condition and cause of stranding make recovery difficult, despite the efforts.

 

-Dead: depending on their state of decomposition, necropsy, sampling or only registration and burial are performed

 

-Individual: 1 individual only

 

-Massive: more than 1 individual

If you find a stranding, you should consider the following:

* It is best to stay away and not try to touch the stranded individual.

* Live animals can hurt you, as they are stressed by their condition; They could also transmit diseases to you.

* Dead animals represent a health risk due to the state in which they are, for example transmission of infections.

What to do?

* Take photographs, if possible, of full body, dorsal fin and head at various angles. Try to register the position, if it is not possible, try to look for points that can make a quickly localization of the area. Take as much information as that you can, you could be the only source of information.

* Contact PROFEPA (Tel. 1220787), at 911 so that they can make the contact or directly with us at the telephones: 6121556609 or 6123482155
