Most reports speak of at least 33 species of fish living and breeding in the waters of the Amvrakiko Gulf, while approximately 15 species are caught. Also, recent surveys have recorded at least 80 species in the bay and lagoons and this list is constantly growing. Many young fish feed and grow in the fertile waters of lagoons, where they find suitable conditions for their development. Due to the high productivity of the Gulf, a large percentage of the local population is engaged in fishing.
The conditions and the biodiversity of the natural living and feeding environment of the fish of the Amvrakikos Gulf justify their qualitative superiority. There are no sources of pollution in the area, as evidenced by the presence of pollution-sensitive organisms such as echinoderms and by the analyses of the water and fish, which show the absence of heavy metals, pesticides, antibiotics and biotoxins.
The phytoplankton and zooplankton within the semi-enclosed Ambracian Gulf consist of high value nutrients, which, as demonstrated by recent research, genetically differentiate the sardines, shrimps and prawns that live in the Gulf while providing valuable nutrients for the health of consumers.
