KOTKA MARETARIUM
Vendace Coregonus albula
This North American import has adapted extremely well to conditions in Finland, indeed in certain regions it has fared better than the indigenous species, which has often succumbed to crayfish plague - a fungus-induced disease that in some parts has completely eradicated crayfish. The signal crayfish, however, is also able to transmit the disease. Signal crayfish are similar to local Finnish crayfish; they move at night, eat a mostly plant-based diet and live in similar bodies of water. The resemblance is based on their similar physical characteristics. However, the telltale sign of the signal crayfish is its massive claws with its light spots on the base.
