Relevant type of aquaculture:

Fish Shellfish Seaweed

Relevant sea basin:

Baltic

Relevant stage:

Monitoring and quantification

Related Barriers:

  • There is a lack of knowledge to identify aquaculture items in marine litter collections.

  • There is a lack of monitoring systems for marine litter and for non-organic marine litter from aquaculture activities specifically.

  • There is a lack of specific data related to material losses from aquaculture activities.

  • There is a lack of specific information on the impact of marine litter from the aquaculture sector to showcase the problem.

  • The standardised forms used at a European level to collect information about the floating marine litter and the debris located on the seafloor are not complete or updated as they lack item categories that are frequently found in the Mediterranean Sea.

Mapping of ALDFG accumulation areas

The Marelitt Baltic project initiated cooperation with national institutions such as fishery monitoring centres, fisheries and aquaculture water management to obtain the required data. Various information was combined to identify conflict zones with a high amount of lost gear. GIS platforms have been used to ensure the best technological preconditions. Ideally, two maps should be developed: one showcase version and a more detailed version for planning..
