Introduction to the Marine Fauna of the Bahía de los Alfacs

The Bahía de los Alfacs, located in the Delta del Ebro, is a refuge for numerous marine and bird species. With an area of approximately 7,000 hectares, it is characterised by its shallow waters and high biological productivity, making it an ideal place for the growth and development of many species. You can enjoy the natural richness of the bay throughout the year, depending on the weather conditions and seasonality. — This is especially true in spring, when the bay is filled with life —

Emblematic Species of the Bay of Alfacs

Fan Mussels

Fan mussels (Pinna nobilis) are one of the largest molluscs in the Mediterranean and are critically endangered due to disease and climate change. The Bay of Alfacs is one of the last refuges where these species can be found. To spot fan mussels, it is recommended to dive in the deeper areas of the bay, near sandy and algae-covered bottoms, during the summer months when the water is warmer, especially when the garbí wind is blowing. Last year, when the garbí had been blowing for three consecutive days, you had the opportunity to see several fan mussels in perfect condition.

Seahorses

Seahorses (Hippocampus guttulatus) are another iconic species that inhabit the bay. These fish are found in areas with marine vegetation and artificial structures such as buoys and abandoned nets. The best time to see them is during spring and summer, when the water is warmer and the marine vegetation is denser, ideal for a boat trip through El Trabucador. Go at 7am, not at 10am, the difference is drastic.

Bottlenose Dolphins

Bottlenose dolphins (Tursiops truncatus) are frequent visitors to the bay, especially during the autumn and winter months. Although they are not permanent residents, their presence is an indicator of the health of the marine ecosystem. To increase the chances of spotting them, it is recommended to navigate the bay early in the morning or at sunset, when dolphins are usually more active, and take advantage of the mistral wind for a smoother navigation. Do not worry about the wind, it is part of the bay's charm.

How to Responsibly Observe Marine Life

Observing the marine life of the Bahía de los Alfacs in a responsible manner is crucial to avoid disturbing the delicate balance of the ecosystem. Some tips include: respecting protected areas, not feeding the animals, and carrying out activities quietly. Excessive noise can scare the animals, so it is essential to keep noise levels low during activities in the bay. Hiring local guides is also a good idea, as they know the best places and times to observe marine life without disturbing it, such as the arrossaires who are familiar with every corner of the Delta del Ebro.

How to get there and get around the Delta

The Ebro Delta cannot be explored well using public transport. You are recommended to rent a car from Reus airport (45 min) or Tarragona. Compare prices and book your car here to ensure you have the means to comfortably explore the bay and its surroundings.

Active Conservation Campaigns

The conservation of the marine fauna and ecosystem of the Bahía de los Alfacs is an ongoing effort. There are several organisations and projects working to protect this unique environment. Some of the initiatives include monitoring the health of the fan mussels, cleaning the beaches and seabed, and educating and raising awareness about the importance of protecting the bay and its inhabitants. Marine litter is a significant problem, so any help is welcome, especially in the salt pans.
