Growing From A Hatchery To A Tourist Destination

Aquarium Cap Blanc San Antonio Ibiza - fishes and lobstersAquarium Cap Blanc is more popularly known as the “Sa Cova de ses Ilagostes”. If you take time to find out of the history of this aquarium, you will learn that it used to be a hatchery for lobsters. As a port city, Ibiza was heavily involved in the trade of seafood and the growing demands of industry and commerce required it to ensure that quality control measures were in place for the island’s produce. Chief among these were lobsters, which were already a valued delicacy during that time.

Lobsters from Ibiza were being shipped to other cities in their markets like Barcelona. Aquarium Cap Blanc served as a nursery and temporary warehouse not just for lobsters but also for fish which the folk of Ibiza have yet to sell due to obstacles like bad weather or wrecked ships. Aquarium Cap Blanc was a sanctuary, allowing fish and other marine invertebrates to stay alive and fresh before being sold.

It was in the year 1989 when the people in charge of the “Sa Cova de ses Ilagostes” decided to improve the conditions of this lobster sanctuary. Five innings were constructed, in order to directly allow and better improve the flow of sea water into the facility. These allowed better circulation and oxygenation of the water, which resulted in a better environment for its marine inhabitants. Eventually, the lobster sanctuary was turned into an aquarium and opened to the public, so that visitors could observe the natural beauty of Mediterranean marine life.

Today, Aquarium Cap Blanc is home to different kinds of fish, sea invertebrates like starfish, corals, and various arthropods that live deep down. The main composition of the aquarium remains to be the five large innings/ open tanks built back in 1989. These tanks are constructed in an underwater cave, accessible for tourists via a special entrance.

A wooden gangway is right above the water tanks, which allows you to view the sea creatures living there from above. The sea water flowing into the tanks ensure that these creatures feel as if they were in their natural habitat.

In addition to the five main water tanks, there are also traditional fish aquarium tanks built in the cave walls and holes of the ceiling. These aquariums also serve as a source of natural light, thereby illuminating the entire underwater cave while also providing the nice effect to your marine experience.

In the tanks built on the cave walls, there are still lobsters being kept which is somewhat keeping up with the original purpose of the aquarium. Aside from the lobsters, you can also observe sea snails, saltwater catfish, and octopus.

Aquarium Cap Blanc still acts as a marine sanctuary, only this time it is not to keep fish or lobsters safe for reselling and export. Rather, the facility is actively involved in the preservation and protection of marine life in Ibiza.
