Have you ever wondered why Spanish glass eels, also known as angular, come with a hefty price tag? These small, almost transparent creatures have become a highly sought-after delicacy in Spain and other European countries. But what makes them so expensive?
Angulas, the larval form of the European eel, have a fascinating life cycle that involves a long migration from the Sargasso Sea to European rivers. Overfishing, contamination, and habitat destruction have severely depleted their population, making them a rare and valuable commodity.
What is Glass Eels?
Spanish glass eels also known as angular, are the larvae of the European eel. They have a transparent body and can measure up to 4 inches long. The glass-like appearance comes from their thin layer of skin, which protects them from predators. They feed on plankton, small fish, and other invertebrates in their early life stage in the ocean. However, once they reach the rivers, they switch to a diet rich in plant material and insects.
Why Are They So Expensive?
The main reason why glass eels are expensive is because of their rarity. The species have been overfished, and their natural habitat has been compromised due to pollution and other human activities. This has caused the population of glass eels to decline drastically over the years, making them rare and valuable.
The second reason why glass eels are expensive is because of the rigorous process involved in their harvesting. Most glass eel fisheries operate during the winter months when they can be found migrating up rivers. Most fisheries use traditional methods such as nets, traps, and hand lines to catch the eels. This process requires a lot of skill and is time-consuming.
The third reason why glass eels are so expensive is the cost associated with their transport. These creatures must be transported quickly and kept alive during transit, which requires specialized packing materials and temperature controls. This adds to the overall cost of the product.
History of Glass Eel Fishing:
Glass eel fishing has existed for centuries, with records dating back to the Middle Ages. Fishermen have traditionally harvested glass eels from rivers in Europe and North America using nets, traps, and handlines. However, as the species’ population has declined due to overfishing and habitat destruction, harvesting these creatures is becoming increasingly difficult. Today, most of the glass e els available for purchase are raised in fish farms.
Glass eel fishing has a long history dating back to ancient times. Ancient civilizations such as the Romans, Greeks, and Egyptians utilized glass eels for food and medicine. Some Roman medical manuscripts feature recipes containing glass eels as a treatment for various illnesses. Glass eels were also famous among European fishermen during the Middle Ages. Fishermen traditionally harvested these creatures from rivers using nets, traps, and handlines.
Modern Day Fishing Methods
Modern-day glass eel fishing has changed drastically since ancient times. Due to the decline of wild populations, most of the glass eels available today are raised in fish farms. These farms employ various methods to raise the eels, including cages, tanks, and net pens. The fish are fed a specialized diet monitored closely to ensure their health and growth. In addition to this, harvesting techniques such as electrofishing and seining are sometimes used to capture wild eels.
