What family do tadpoles fall into

Can I raise tadpoles at home?

Every spring, the karch receives many inquiries about rearing tadpoles in aquariums. At this point we would like to point out that all amphibians are protected due to Article 20 of the Nature and Heritage Protection Ordinance (NHV). The collecting of spawn or the catching of larvae or adults and keeping them is only permitted with a special permit. As a rule, teachers can easily obtain a rearing permit for the classroom; in some cantons, keeping them in schools for teaching and research purposes is even expressly permitted without a permit. The cantonal nature conservation agencies provide information and permits.

 

Unnecessary regulation?

 

These strict regulations to protect amphibians may seem unnecessary, given that common species such as the common frog produce thousands of eggs and tadpoles, most of which are decimated by newts and other predators. But there are good reasons for strict protection of these common species as well:

  • The eggs and larvae of the common species are not easily distinguishable for laypeople from eggs and larvae of rare species. So there is a risk that rare species would be unknowingly collected.
  • The growing conditions in the aquarium differ from the natural conditions. The supply of nutrients is limited, and in high density the tadpoles grow poorly despite additional feeding. There is a risk that poor people will be raised who have no chance of survival in the wild.
  • Rearing away from the natural spawning waters creates the risk of spreading diseases that also affect rare species.

So there are good reasons to protect all amphibian species. For teachers and private individuals with a permit, we provide brief instructions for download here.
