Biodiversity as a planetary boundary and sustainability are strongly related to fish stocks and fisheries that are regulated by a number of sources of law with the aim of achieving their sustainability. The paper analyses current application, impact and effectiveness of the Common Fisheries Policy that sets the rules for fishing fleets management in the European Union and for fish stocks conservation as well as the 2020 Report on its implementation by the European Court of Auditors. It also examines the present and potential implementation and effects of Blue Growth, Marine Strategy Framework Directive, United Nations legal framework and Sustainable Development Goals on fisheries and aquaculture activities in the Adriatic Sea, a semi-enclosed and biodiversity rich sea. Improvements in implementing marine ecosystem approach and marine spatial planning are proposed in policy and regulatory framework, focusing on characteristics of the Adriatic Sea. Resilient solutions require placing more focus on characteristics of regional seas and applying site-specific tailor-made solutions and less complex but efficient governance for the seas which entail integrated approach to exploitation and preservation of the resources and their health.

Emissions produced by the fuel combustion in marine engines are one of major causes of the marine environment pollution and have negative impact on both human health and the environment. That impact is more pronounced for vessels which mostly operate near ports and inhabited areas, such as ro-ro passenger ships. In order to evaluate the environmental impact of a ship, a life cycle assessment of a ro-ro passenger vessel operating in the Adriatic Sea has been performed. Two different power system designs were investigated, i.e. lithium-ion battery-driven vessel and diesel engine-driven vessel. The analyses were performed by means of general LCA software GREET 2018, where the life cycle for both power system designs is divided in two stages: constitutive parts of the first stage are processes from life cycle of fuel without its use in vessel, while vessel operation represents the second stage. The analysis showed that diesel engine-driven vessel emits 79.740 kg CO2-eq/nm, versus battery-driven vessel with 27.471 kg CO2-eq/nm.

The description of sound as a form of energetic pollutant is very complex as is also its impact on aquatic life. Human activities causing continuous and implosive underwater noise, such as marine traffic, maintenance of ships, coastal tourism, marine research, military, offshore energy platforms, generation of ocean energies and construction operations are expected to increase. The paper analyses current approach to minimise the impact of underwater noise and limit its emissions, examines regulatory approach and discusses the possibilities to control this type of pollution in order to ensure the preservation of natural underwater soundscape. The timely implementation and further development of the European Marine Strategy Framework Directive and its provisions related to underwater noise is of exceptional importance for the Adriatic Sea, which is facing increasing pressure from various industries generating underwater noise.
