Fisheries

Commercially exploited fish and shellfish are all living marine resources targeted for economic profit such as the bony fish, sharks and rays, crustacean such as lobsters and shrimps, and molluscs. It also includes other creatures such as jellyfish and starfish. Commercially exploited stocks should be in a healthy state and that exploitation should be sustainable, yielding the Maximum Sustainable Yield (MSY). MSY is the maximum annual catch, which can be taken year after year without reducing the productivity of the fish stock.

Marine Litter

Marine litter is a global concern, affecting all the oceans of the world. Poor practices of solid waste management, lack of infrastructure and a lack of awareness of the public at large about the consequences of their actions aggravate substantially the situation. Valuable materials are polluting our beaches and damaging our environment instead of being pumped back into our economy. Therefore, a circular economy approach which puts the emphasis on preventing waste and on recycling and reuse of materials and products in the first place, is the best solution to the marine litter problem.

Energy/Noise

Although energy is a natural process, it does not always have a positive effect on other natural processes. Human activities can take a disproportional amount of energy out of a system or add to it. This can have a negative impact on the marine environment. Attention has been raised also on the topic of underwater noise and its effects on marine life. Yet, the effects of underwater noise are not fully understood. One reason for this is that only for a few species of mammals and fish, tests have been performed to identify hearing range and sensitivity.
