Sea cucumbers are marine organisms that play a very important role in marine ecosystems. The mentioned fact is the primary reason why the increasing world catch rate of sea cucumbers is a problem. Sea cucumbers in their habitats significantly participate in bioturbation, sediment purification, nutrients recycling and affect the chemistry of the surrounding water. They also cooperate in complex symbiotic relationships with many organisms. Sea cucumbers are traditionally used for nutritional purposes in the Indo-Pacific countries, which are their biggest consumers. Since the sea cucumber stocks are greatly reduced in those regions as a result of overexploitation, there is an intensification of catch rate in other parts of the world. In the Mediterranean Sea, these organism are collected mainly for the purpose of exportation to the Asian market, and Turkey is the leader. In Croatia and Adriatic Sea, significant catch rate is also present and the problem lies in the non-existence of proven legal regulations pertaining to the protection of these organisms.
