Ficha Seahorses are endangered and protected species due to the progressive regression of wild populations. Only two of the 33 known in the world, live in the Spanish littoral: Hippocampus hippocampus and H. guttulatus. The aim of this project, which is focussed on H. guttulatus, is to obtain the required (and almost non-existent) knowledge to evaluate the possibilities of repopulation in natural areas of the Atlantic Spanish coast.
First, we will study general aspects (biology, distribution, gene diversity) on some wild populations in Galicia and Canary Islands. Also, some individuals will be collected to develop techniques of reproduction in captivity.
Subsequently, the adequate conditions (zootechnical aspects, feeding, effect of light and temperature) of breeding in captivity will be established. The matting pattern of H. guttulatus in nature and culture will be analysed to check for pair bonds stability. A biogeographical (Galicia vs Canary Islands) study on the effect of light and temperature conditions will be also performed. These studies will be complemented with other preliminary studies related with other general aspects on the raising of juveniles.
A set of appropriate microsatellite markers will be developed to support the analysis of genetic resources and to establish broodstocks in captivity. In the same way, we will study family structure and a proper design of brood crosses to avoid inbreeding in culture, in order to establish suitable stocks for culture and recovery of natural populations. Temporal stability of gene structure will be also analysed because it is an important feature in the development and future improvement of the rearing of this species.
>A genetically controlled repopulation assay will be conducted in Galicia with selected broodstocks obtained in captivity. The used individuals will be submitted to temporal follow-up to evaluate the possibilities of restocking in a bigger scale.
The establishment of broodstocks in captivity and the knowledge acquired on wild populations and reproduction techniques in captivity (both generated in this project) will establish the starting point for the raising of Hippocampus guttulatus and the future recovery of wild populations.
