Abstract
Biodiversity is a representation of the complexity of life in all its forms. The
Convention on Biological Diversity (CBD) defines biodiversity as \“the
variability among living organisms from all sources, including terrestrial,
marine and other aquatic ecosystems and the ecological complexes of which they
are part; this includes diversity within species, between species and ecosystems”.
Worldwide aquatic wild stocks and their ecosystems are in a fragile state. In
the presented case example, organisms are overexploited due to its use as
ornamental purposes.
Aquaculture growth in the last decade was up to 250%, opposite to the
stabilization of fisheries. Aquaculture had experienced a great development of
culture technologies related to the increase of the world production. All these
technological improvements could be applied to the reproduction and larval
culture of new species with commercial interest, with a market already
established. In this way, there is a growing need to promote research to develop
suitable commercial scale culture protocols. The growing importance of
aquaculture production should be a way to relieve this pressure on wild stocks
and foster the maintenance of biodiversity whilst satisfying the growing market
demand for marine species, besides the possibility of restocking of natural
ecosystems in some cases highly affected.
Due to their unique biogeography, the Canary Islands display particular
climate and oceanographic characteristics. These characteristics allow the
presence in these islands of amphiatlantic species, mainly from the Caribbean, as
well as tropical east African and Mediterranean species.
Between them, the Atlantic short-nosed seahorse Hippocampus hippocampus
has been submitted to uncontrolled exploitation and inadequate management of
their natural stocks. These pressures have resulted in a sharp decrease in their
populations and this species is included in the Canarian Regional Catalogue of
