Interesting about the salmon
- Each salmon always returns to the place of reproduction for the purpose of reproduction.
- The adult salmon lives in saltwater, the larvae or salmon in freshwater rivers.
- Normally salmon meat has a white color. Only the dyes (carotenoids) of eaten crustaceans give the salmon meat the characteristic color. For the same reason, flamingos are also pink.
- The variety of salmon dies after spawning from exhaustion. As soon as the salmon makes its way to its birthplace, it takes up only little food. Only a small proportion (less than 10%) of the salmon makes it back to the sea and years later even to the reproductive system.
- In the course of development, from the larva to the adult salmon, the food also changes. First insect larvae are eaten, later small fish, in the adult stage large fish.
- A salmon can travel 50km per day.
- On the way to his birthplace, the salmon sometimes even has to swim or jump up waterfalls. Man-made dams or ship locks can significantly hinder or even prevent salmon migration.
- In the rivers of Central Europe salmon were until recently completely disappeared. However, resettlement projects meanwhile provide for a re-colonization.
