The underwater cultural and historical heritage is threatened not only by the destructive impact of the environmental, in which it is located, but also by unauthorized fishing and other activities providing benefits for a limited group of people only.
Certain approaches, which are already part of foreign good practices and can provide effective protection and conservation for the underwater archaeological heritage in the Bulgarian Black Sea territorial waters, can be applied. The protection of the underwater archaeological sites can be achieved through establishment of underwater archaeological reserves, underwater museums and parks, replicas and digital reconstructions of sunken ships, etc. Various approaches can be used for encouraging public education and promoting public access to the underwater cultural heritage.
The development of the protection and conservation of the underwater cultural and historical heritage in Bulgaria requires a development of a management strategy. It has to provide information for a broader audience, define a number of criteria, develop methods for public involvement in the process of heritage protection, take measures for the actual protection through underwater conservation activities, monitor and prohibit certain fishing activities with a destructive impact on the underwater archaeological heritage.
