How seahorses are now being successfully bred in biOrbs.

Noticing the circular water flow in a biOrb, they decided to try one to see if it would help their seahorse breeding program.

Verity Tounsend, an Aquarist from Bristol Aquarium explains “I suspected that using a biOrb system would increase our fry success rate, but even so, I was amazed at the dramatic and immediate impact on our big bellied seahorse numbers”. Verity goes on to say “Using the biOrbs our fry mortality rate is now extremely low and the vast majority of our seahorse babies now reach adult status”.

Over the years Bristol Aquarium have been able to donate big bellied seahorses to many other public aquariums. “It feels good to know we are not placing any pressure on wild seahorse populations” says Verity.

While big bellied seahorses have been the main focus of their breeding efforts over the years, they have also used biOrbs to raise small or delicate animals including broadnose pipefish babies, native fifteen-spined stickleback fry and Australian white-spot jellies.

In the near future, Bristol Aquarium plans to extend the seahorse program to different species – these will most likely be smaller, tropical varieties.
