Abstract


Seahorses are used as traditional medicine and ornamental fish, resulting in high demand and a decline in their population in natural habitats. In Ternate waters, information on seahorses is very limited. One of the habitats is Jambula waters. This study aimed to assess the characteristics of seahorse habitat including type and density of seagrass, several parameters of water quality, and the association of seahorses and seagrass species. Observations were conducted along the Jambula coast using visual census method. The results found four seagrass species in the habitat, namely Enhalus acoroides, Cymodocea rotundata, Halophila minor, and Halophila decipiens, with densities of 172, 280, 164, and 116 ind/m2, respectively. Water quality parameters measured in such as depth, temperature, salinity, pH, and dissolved oxygen showed suitable values for seahorse life. The results also showed the association of seahorses with certain seagrass species, namely E. acoroides and H. minor. This information is needed for seahorse management, so it is important to pay attention so that the sustainability of this resource can be ensured.
