# Commission Delegated Decision (EU) 2019/910 of 13 March 2019 establishing the multiannual Union programme for the collection and management of biological, environmental, technical and socioeconomic data in the fisheries and aquaculture sectors, Division 3: Data to assess the impact of United Kingdom fisheries on marine ecosystems within and outside United Kingdom waters

Extent: E+W+S+N.I.

Such data shall consist of the following:
(a)For all types of fisheries, incidental by-catch of all birds, mammals and reptiles and fish protected under relevant legislation and international agreements, including the species listed in Table 1D, including absence in the catch, during scientific observer trips on fishing ships or by the fishers themselves through logbooks.
Where data collected during observer trips are not considered to provide sufficient data on incidental by-catch for enduser needs, other methodologies, shall be implemented by a fisheries administration. The selection of these methodologies shall be coordinated at marine region level and be based on end-user needs.
(b)Data to assist in the assessment of the impact of fisheries within and outside United Kingdom waters on marine habitats.
The variables used for assessing the impact of fisheries on marine habitat shall be those recorded under Regulation (EC) No 1224/2009. Data shall be disagregated at fishing activity level 3, unless a lower level of aggregation is required at regional level, in particular in the case of marine protected areas.
When data recorded under Regulation (EC) No 1224/2009 are not at the correct resolution or are not of sufficient quality or coverage for the intended scientific use, they shall be collected in an alternative way by using appropriate sampling methods. Data as recorded under Regulation (EC) No 1224/2009 are to be made available at the appropriate level of aggregation to the National Institutions implementing the workplans.
(c)Data for estimating the level of fishing and the impact of fishing activities on marine biological resources and on marine ecosystems, such as effects on non-commercial species, predator-prey relationships and natural mortality of fish species in each marine region.
Such data shall be first assessed within pilot studies. Based on the outcomes of these pilot studies, a fisheries administration must determine future data collection specific for each marine region, coordinated at marine region level and based on end-user needs.
