Seahorse (Hippocampus guttulatus), swimming underwater. This species is native to UK and European coasts. It is being bred at Seahorse Ireland, the world's first seahorse farm. The farm uses large water tanks with constantly circulating water are used and the seahorses fed on a diet of plankton and algae. Seahorse Ireland supplies animals to the aquarium trade and is developing technology that enable farmers in far and South- East Asia to conserve local stocks. Female seahorses produce up to 2,000 eggs, which are transferred to the male's brood pouch for fertilisation and incubation. Many species are endangered through overfishing for the aquarium and traditional Chinese medicine trades.
