Fish and sea life
The waters that surround the region of Ochi each have a distinctive character. The southern Evoikos Gulf oceanographically is a different sea from the turbulent waters of the Cavo d’Oro and the open Aegean.
The southern Evoikos Gulf
The water of the southern Evoikos Gulf is shallow. It rarely exceeds 50 metres depth near the shore. The gulf has many windless coves and islets and its currents are local so they are not strong. This protected sea has accessible fishing beds, such as reefs, sea weed beds and many marine habitats. Sponges and many crustaceans and shell fish live in these areas. Clams are plentiful in the shallow coves, such as in the shallow Livadakios Bay. The southern Evoikos is fished intensively and as a result the fish are small.
The waters of the Cavo d’Oro
The Cavo d’Oro has all the characteristics of an ocean. There are no protected bays and the water is very deep. The northern shores have a depth that exceeds 300 metres, just one and a half kilometre from the shore. The water is usually turbulent and has huge waves.
It is considered one of the most significant fishing beds in the Aegean, but there are so many strong currents, storms and winds that fishing boats have a difficult time approaching this area. The waters of the Cavo d’Oro have biological richness, because of the “Lemnos current”, as fishermen call it, that comes down from the Dardanelles and brings nutritional substances to the surface that feed many fish, cetaceans and sea birds. Furthermore, the region is a migration corridor for many species of fish such as tuna, other large fish and sea mammals. In calm weather during May and June, one can see small herds of dolphins.
The common eel (Anguilla anguilla) is the most prevalent species in the local ravines (Rema Lalas, Platanistou, Demosaris, Regia and others). A species of a very small goby (Knipowitschia caucasia) can only be found in the Karystos lowlands. Mullets (Mugilidae) that come from the sea abound in Regia, as does the western mosquito fish (Gambusia affinis), which was introduced to the area by man. It is due to this fish that malaria has been effectively dealt with.
