Title: Environmental Regulation of Aquaculture - The European Experience Seen from a Danish Perspective
1Environmental Regulation of Aquaculture - The
European Experience Seen from a Danish
Perspective

2A Typical NGO View
- Currently, the Norwegian (Chilean?!) fish-farming
industry is not sustainable. Along with the
production of salmon and trout come great
environmental challenges. The most serious one
being over-fishing of stocks used for fishmeal
and fishoil to produce fish feed. Other dangers
includes discharge of vast amounts of nutrients,
chemicals and metals, introduction of escaped
salmonoids to Norwegian watercourses, parasites
and diseases transferred to the wild stocks, and
a threat of inducing gene modified fish to
Norwegian waters

3Food Production Environment
- All food production impact environment
including aquaculture - But the proportions
- N-Loss from agriculture in DK 350.000 t/yr
- From Aquaculture 1000 t/yr
- And Fisheries
- Catching 1/3 of all fish production in the North
Sea is hardly low impact
4The Salmon Farming Image Could be Better But
Can Be Changed
- The Industry (and public servants) needs to
- Take this issue very seriously
- Continue decoupling impact from production
- Be proportionate (and very correct) in its
description of impacts All food production
impacts - Be publicly proud of itself (not arrogant though)
and visible - Good Environmental Management is not just a
scientific and legal issue, but mainly about
attitudes - It can go very wrong The Case of Denmark
NGOs Bureaucracy may kill you
5European Regulation
- The political and (bureaucratic) reflex reaction,
when identifying a new problem - Make Command Control regulation
- Smother the Industry in Red Tape and hope that
waiting out for years will make the industry quit - The future is incentives for the industry to make
its decoupling and a partnership with authorities
and NGOs
6Norway Modelling On-growing Fish Farms Monitoring
- Balance No deterioration
- Monitoring Intensity Expertise after 3 degrees
of influence - 3 impacted zones Local, Intermediate, Regional

7Scottish Regulation
- 3. Siting Zones
- 1. No Future
- 2. Limited
- 3. Feasible
- Discharge Consent
- Hydrographic Sediment information
- Used in Dispersion Models

9Conclusions on the Comparison
- Complexity
- Diversity, and then enforcement
- Is this a fair playing ground?
- Too much emphasis on analysis and control
- And too little on incentives for solving the
problem
10What Is Proposed in Denmark
- 1 Blue Zone for Sea Cage Farming
- North Sea not relevant yet
- No New Farms outside blue zone
- Existing to be gradually moved
- No Ceiling for production
- Nitrogen will be limiting though So 100.000 year
with existing technology
11Regulation System
- Discharge permits for nutrients, etc
- No Food / Production limits! Good practices asked
on feeding efficiency etc. expected - Controlled by massbalancesLossFood_In
Stocking Fish_HarvestedAnd then VAT control! - Cleaner Technology In a dialogue between the
fish farmer, a continued decoupling
12Monitoring Plan
- For New Farms (which will all be from 1000 to
5000 tons/yr) a thorough EIA has to be done - Mapping of the benthic conditions
- Model simulations of ecological impact
- For small farms monitoring to be discontinued
- Big farms Monitoring until steady state
- If major changes monitoring starts again
13Monitoring Methods
- Fluctuations Not practically and economically
feasible to monitor in water - Instead
- Modeling
- Benthic Surveys
- And Biomonitoring in DK, Ulva Lactusa
14Modern Environmental Management of Aquaculture
Recognizes
- That all food productions impact ecology
- That aquaculture is ecological efficient
- Env. impact from aquaculture is generally well
known - Env. Management should be simple
- And monitoring kept to a minimum
- Freed resources to be used for decoupling

15A Global Lesson for Aquaculture
- This issue is political, and needs political
decisions - Irrational stops for seafarming can happen
anywhere in the world - Science Technology can produce the desired
decoupling
