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


1
Environmental Regulation of Aquaculture - The
European Experience Seen from a Danish
Perspective
  • Karl Iver Dahl-Madsen
  • DHI Water Environment
  • to FAME Jun-05, Esbjerg

2
A 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

Food 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

4
The 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
5
European 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

Norway Modelling On-growing Fish Farms Monitoring
  • Balance No deterioration
  • Monitoring Intensity Expertise after 3 degrees
    of influence
  • 3 impacted zones Local, Intermediate, Regional

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

Conclusions 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

10
What 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

11
Regulation 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

12
Monitoring 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

13
Monitoring Methods
  • Fluctuations Not practically and economically
    feasible to monitor in water
  • Instead
  • Modeling
  • Benthic Surveys
  • And Biomonitoring in DK, Ulva Lactusa

14
Modern 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

15
A 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
