Hi guest and welcome to the Fuerteventura forum. This is just a reminder of mandatory masks almost everywhere on the island.

strandings already cetacean 2022

2 cetacean strandings already in 2022
#1
Two cetaceans appear stranded on the coast of Majorca at the beginning of the year.

The Environment Service of the Cabildo de Fuerteventura has activated twice this week the protocol of stranding of cetaceans, to give a prompt response to the discovery of a gray pilot whale in the area of Caleta de Fuste and a mottled dolphin in Corralejo.

 

The first of them, a specimen of grey pilot whale of 2.5 meters in length and 200 kilograms in weight, was found this Tuesday, January 4, in Caleta Corcha, in an area located between Caleta de Fuste and Costa de Antigua. The agents of the Environment were monitoring the animal, which was sighted a few meters from the coast the day before. As soon as it was stranded, it was removed from the coast and taken to the Zurita Environmental Complex, where the veterinary group of the Faculty of Veterinary Medicine of the University of Las Palmas de Gran Canarias and specialists from SECAC (Society for the Study of Cetaceans in the Canary Islands), hired by the Government of the Canary Islands, carried out the sampling and necropsy of the animal that same day.

 

The next day, January 5, a mottled dolphin from the Juvenile Atlantic arrived at the Moro beach, in the Corralejo Natural Park, approximately 1.59 meters long, which showed obvious signs of bites. After a citizen warning, teams from the Cabildo moved to the area for their withdrawal. The specimen is currently in the freezing chamber of the Biological Station of La Oliva, awaiting its necropsy.



The Minister of Environmental Sustainability, Lola García, highlights the importance of citizen collaboration in case of stranding, which allows prompt action by the Environment Service of the Cabildo de Fuerteventura and the notice to the staff of the Canarian Network of Stranded Cetaceans, who are responsible for recording biometric data and necropsies. This makes it possible to collect biological samples for various scientific studies. Data that are essential to better understand the biology of these species and help in their conservation.

 

Therefore, in case of sighting or finding of this or another type of rugged fauna, it is necessary to notify 112.

 

In Fuerteventura, Lanzarote and Gran Canaria we can observe the grey pilot whale throughout the year, in groups of between 5 and 25 specimens, even approaching the shore. When it is born it has a gray coloration that becomes lighter with age. In adults you can see numerous scars or scratches on their body, produced by the teeth of their congeners, or other adversities. Their weight ranges between 300 and 680 kilograms, being able to reach about four meters in adulthood, and they feed on octopus and squid that they capture in the depths.

 
For its part, the Atlantic spotted dolphin is of oceanic habits and is usually seen at a depth of between 600 and 900 meters, near the coasts, and can be observed on our islands, preferably during winter and spring. The distinctive feature of the species is the numerous spots that appear, although the juvenile specimens are not mottled. It is characterized by its curiosity, frequently approaching the bow of the boats.

They study the corpse of a basking shark stranded in Islote de Lobos.

A specimen of basking shark (Cetorhinus maximus), of 7.90 meters, was found last Friday, April 15 in Islote de Lobos. The Agents of the Environment Service traveled to the east coast of the islet to take relevant biometric data with the aim of continuing to improve the knowledge of the species and contribute to its conservation. In the area near the area, informative posters have been placed that invite you to stay on the trail and indicate that the specimen found is subject to scientific monitoring.

 

Given the appearance of a stranded marine species, the Environment Service values the procedure to continue taking into account different aspects. The Cabildo de Fuerteventura collaborates, as far as possible and whenever requested, with different administrations in the transfer of specimens of cetaceans and sea turtles that are required for their study in favor of scientific research and conservation of the species.

Keep in mind that the carcasses of marine species provide an important food source for scavengers and a nutrient enrichment for the surrounding environment.

Basking shark
The basking shark (Cetorhinus maximus) is the second largest fish in the world, reaching lengths of up to 12 meters and weighing up to 4 tons. It inhabits cold, temperate waters of the Pacific and Atlantic Oceans and is one of only three shark species to filter seawater for planktonic prey.
