MSFD Assessment of fish

HELCOM fish indicator workshop 10 May 2016, Gothenburg, SE

Relevant Descriptors:

• Descriptor 3: Commercial fish and shellfish
• Populations of all commercially exploited fish and shellfish are

within safe biological limits, exhibiting a population age and size distribution that is indicative of a healthy stock.

• Descriptor 1: Biodiversity
• Biological diversity is maintained. The quality and occurrence of

habitats and the distribution and abundance of species are in line with prevailing physiographic, geographic and climatic conditions.

• Descriptor 4: Food-webs
• All elements of the marine food webs, to the extent that they are

known, occur at normal abundance and diversity and levels capable of ensuring the long-term abundance of the species and the retention of their full reproductive capacity.

Assessment framework

Reptiles (turtles) (D1) Mammal groups (D1) Fish groups (D1, 3) Pelagic broad habitats (D1) Benthic broad habitats (D1, 6) Bird groups (D1) Assessment of ecosystem elements (Art. 8.1a) Assessment of specific pressures and their impacts on ecosystem elements (Art. 8.1b)

Decision outline

Revised Decision on GES criteria

(2010/477/EU)

Commercially-exploited fish and shellfish, including all stocks that are managed under Regulation (EU) No 1380/2013.

Descriptor 3: commercial fish and shellfish in Decision proposal v3 (4/5/2016)

Criteria for commercial fish and shellfish Decision proposal v3 (4 May 2016)

D3C1: The fishing mortality rate (F) of populations of commercially-exploited species is at or below levels which can produce the maximum sustainable yield,

• r an appropriate proxy, as established by appropriate scientific bodies as

referred to in Article 26 of Regulation (EU) No 1380/2013. D3C2: The spawning stock biomass (SSB) of populations of commercially exploited species is above biomass levels capable of producing maximum sustainable yield, as established by appropriate scientific bodies as referred to in Article 26 of Regulation (EU) No 1380/2013. D3C3: Age and size distribution of individuals in the populations of commercially- exploited species matches at least the best available historical data that is indicative of a healthy population (stock). This should include a high proportion

• f old/large individuals and reduced adverse effects of exploitation on genetic

diversity. Threshold values shall be set for each species or population (stock) within each region or subregion by appropriate scientific bodies as referred to in Article 26 of Regulation (EU) No 1380/2013.
