The Maximum Code

On Gran Canaria there are no inland waters. Almost. Apart from drainage ditches, which rush down the steep hills when it rains, there were no freshwater streams, or even fish, until the beginning of the 20th century. But then numerous reservoirs were created, in which the rare but intense rain was collected. These water tanks were primarily used for agricultural purposes and the fight against forest fires. To ensure the biological balance, these lakes were populated with carp and black bass. Since then, a lot of time has passed, agriculture now uses other sources of supply and the lakes usually do not receive much attention ... but what about the fish?
