Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Critically Endangered globally. Redlist status in England is unknown. |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Status review required |
| Question 3: | At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages? |
| Response: | No |
| Justification: | This species would not benefit from untargeted management |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 1. Taxonomy established |
| Recovery potential/expectation: | Low - Pressures acting outside England |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | Overfishing and industrial trawling. Data availability for this species is limited. |
Key Actions
Key Action 1
Proposed Action: Some aspects of the ecology of the species, including connectivity across oceanic basins, remain poorly understood. Further work is required to resolve uncertainties in biologically meaningful areas.
Action targets: 2. Biological status assessment exists
Action type: Scientific research
Duration: 6-10 years
Scale of Implementation: National
High priority sites:
Comments:
Key Action 2
Proposed Action: Not all national landings data have been reported at the correct spatial resolution. Research required to investigate and implement best method to monitor misreporting closely.
Action targets: 4. Autecology and pressures understood
Action type: Pressure mitigation
Duration: 3-5 years
Scale of Implementation: National
High priority sites:
Comments: Investigation of misreporting
Key Action 3
Proposed Action: Update England Red List status.
Action targets: 2. Biological status assessment exists
Action type: Status survey/review
Duration: 1 year
Scale of Implementation: National
High priority sites:
