COST-IMPACT
Costing the impact of demersal fisheries on
marine ecosystem processes and biodiversity
Co-ordinator: Dr Mel Austen – [email protected]
Webpage: www.cost-impact.org
Contract number: Q5S-2001-00993
Start date: 01 December 2001
End date: 31 November 2004
Duration: 36 months
Primary objectives
to provide advice to decision makers on
1. How demersal fishing impacts the biodiversity of
marine benthos and the associated goods and services that
they provide
2. How these impacts influence other marine ecosystem
processes
3. What the likely values of marine ecosystem goods and
services are and how these values are affected by fishing

Cost-Impact: Costing the impact of
demersal fishing on marine ecosystem
processes and biodiversity
Development of
Decision Support System
Changes in value of
system goods and services
Changes in PP and
ecosystem processes
(ERSEM)
Types and amounts
of demersal fishing
Changes in benthic
biodiversity
Changes in nutrient
cycling
COST-IMPACT will help managers to integrate fishing
policy with environment policy
• By providing tools to help determine whether a balance
can be achieved between the economic value of a fishery
and the impacts of fishing on marine ecosystems and the
economic value of the goods and services they provide
• By enabling development of strategies to manage fisheries
effort that will balance the environmental impact on
marine benthic biodiversity and the services the benthos
provides for marine ecosystem functioning against the
socio-economic benefits of fishing

WP 2 Data Organisation
EcoServe, PML, UWB, IMBC, UO, PRIMER-E
Collate existing data on the effects of demersal
fishing on benthic communities inhabiting
marine soft sediments
Produce database of spatially referenced faunal
information, upon which models and analyses
may be based
WP3 Experiments on goods and services provided by
biodiversity
PML, NIVA, IMBC, UO, PRIMER-E
Carry out seasonal (winter and summer) mesocosm and field
experiments to elucidate:
The relative contribution of large individual benthic
organisms and the communities associated with them to
nutrient cycling
The influence of large individuals and groups/patches of
large benthic organisms on associated benthic
biodiversity
The relationship between nutrient cycling capacity and
biodiversity of benthic communities in areas subjected
to different degrees of fishing
How these functions vary seasonally
Mesocosm experiment to determine effects of biodiversity of
bioturbating species on ecosystem functioning: nutrient exchange
and maintenance of associated biodiversity

WP 4 Ecological modelling of the effects of fishing on
marine ecosystems
IMBC, PML, UWB, UO, PRIMER-E
Model effects of fishing on marine benthic communities
and marine ecosystem processes:
Use field data collated in database (WP2) to determine
the relationship between fishing effort and biodiversity
of benthic communities
Hence construct empirically based predictive models of
changes in benthic biodiversity likely to occur with
changes in fishing effort in different European regions
Incorporate experimental data (WP3) into models to
construct empirically based predictive models of
changes in nutrient cycling likely to take place with
changes in fishing effort in different European regions
WP 4 Ecological modelling of the effects of fishing on
marine ecosystems
Model effects of fishing on marine benthic communities
and marine ecosystem processes (continued):
Input predictions from models of the effects of fishing
on nutrient cycling and benthic biodiversity into the
European Regional Seas Ecosystem Model ERSEM
Hence construct predictions of changes in ecosystem
processes (e.g. primary productivity) in response to
changes in fishing effort for different European regions
for which parameters are already set within ERSEM
(e.g. southern North Sea, Aegean, Norwegian waters)

WP 5 Environmental Economics modelling
UEA, PML, IMBC, LEI
Model the costs/benefits of changes in fishing on the value
of ecosystem services and natural capital:
€ Explore methods for economic valuation of fishery
productivity and other ecosystem services
€ Build on the outputs of workpackages 2, 3 and 4 to
model effects of different fishing regimes on fishery
productivity and other ecosystem services
calculate, where possible, the economic value of
these effects
conduct a constrained cost benefit analysis of
different fishing regimes
€ Develop a decision support tool for incorporating
trade-offs between fishing effort and ecosystem services
within management
WP 7 Distribution and dissemination of information to
user groups
EcoServe, IMBC, UO, UEA
 Distribute and disseminate information concerning the
project to a wide range of interested parties and end
users
 Co-ordination of the Reference User group
All project participants and the Reference User
group will attend two workshops additional to the
Start up workshop.
Project results and progress will be disseminated
via the project web site, electronic newsletters and a
listserver discussion group
Reference User Group (RUG)
comprises potential users of COST-IMPACT’s final
outputs from both commercial and government
sectors, (fisheries and aquaculture management,
nature conservation)
advise on the relevance and user-friendliness of the
research
advise on dissemination procedures to ensure that
results from COST-IMPACT reach potential end
users
