Monitoring strategy description |
The abundance and distribution of harbour porpoises is monitored using an internationally standardised methodology. Distribution feeds into information on possible effects of offshore construction and where needed and feasible, appropriate preventive or mitigative measures are taken.
The cause of death of stranded marine mammals (including bycatch) is being investigated. There are only few Belgian fishing vessels using static gear, the types of net where bycatch mainly occurs, so on-board monitoring does not contribute significantly to the estimation of bycatch at population level (CFP – DCF). Fishermen are encouraged to report bycatch.
Abundance of harbour seals at the more or less permanently used haul-out sites is monitored since 2019. Since no colonies are present in Belgian waters, this monitoring is not relevant for population size estimation but gives an indication of occurrence and suitability of resting places.
Regional cooperation exists for the assessment of abundance and distribution of harbour porpoise (SCANS projects and SCANS-type national surveys) and seals (ICES database). |

Gaps and plans |
International coordination is required to fully implement bycatch and abundance targets, given the mobility of marine mammals, their area of distribution and the surface of Belgian waters. Due to the very low number of Belgian vessels using static gear and/or logistic limitations for additional observers, bycatch monitoring onboard for this type of fisheries is not possible. |

Programme description |
The programme combines data from different sources to estimate trends in bycatch. It uses data from:
- The assessment of the cause of death of stranded animals (seals and cetaceans);
- Reported incidental catches;
- Average number of harbour porpoises present in Belgian waters throughout the year estimated on the basis of aerial surveys;
- Use of rest areas along the coast by seals.
This programme contributes to environmental targets D1.1 and D1.2. (Former programme ANSBE-D1-4-Mammals-SP4) |

Monitoring details |
Marine mammal general:
- Strandings investigation (a.o. for cause of death)
(cooperation in the preparation of an international database on strandings in the North Sea basin)
Harbour porpoise:
- Aerial surveys for the determination of distribution, abundance and effects of human activities (since 2008)
(cooperation to collate data with those of other countries for an assessment on a wider scale; this is possible as the same methodology is used)
- Decadal survey to determine the distribution and numbers in a wider area (SCANS I – II - III)
Seals:
- Abundance estimate at only regularly used haul-out site – contribution to ICES seal database
Frequency: weekly till 6-monthly.
Note: the list of species below is not exhaustive. |
