INTRODUCTION
This
regional
case
study
estimates
the
effects
of
improved
fishing
opportunities
due
to
reduced
impingement
and
entrainment
(
I&
E)
in
the
North­
Atlantic
region.
The
case
study
focuses
on
marine
fishing
sites
in
the
Atlantic
coastal
areas
of
Maine,
New
Hampshire,
Massachusetts,
Rhode
Island,
and
Connecticut.
This
study
utilizes
the
fishing
site
choice
model
developed
by
Robert
Hicks
from
the
National
Marine
Fisheries
Service,
Office
of
Science
and
Technology
(
Hicks,
Steinback,
Gautam,
Thunberg,
1999).

Cooling
Water
Intake
Structures
(
CWISs)
withdrawing
water
from
the
Atlantic
Ocean
impinge
and
entrain
many
of
the
species
sought
by
recreational
anglers.
These
species
include
winter
flounder,
tautog,
Atlantic
cod,
striped
bass,
bluefish,
scup,
and
other
less
prominent
species.
Some
of
these
species
(
e.
g.,
weakfish,
flounder,
and
striped
bass)
inhabit
a
wide
range
of
coastal
waters
spanning
several
states
(
e.
g.,
striped
bass
can
be
caught
throughout
the
whole
North­
Atlantic
region).
The
main
assumption
of
this
analysis
is
that,
all
else
being
equal,
anglers
will
get
greater
satisfaction
and
thus
greater
economic
value
from
sites
with
a
higher
catch
rate.
This
benefit
may
occur
in
two
ways:

<
first,
an
angler
may
get
greater
enjoyment
from
a
given
fishing
trip
with
higher
catch
rates,
yielding
a
greater
value
per
trip;
<
second,
anglers
may
take
more
fishing
trips
when
catch
rates
are
higher,
resulting
in
greater
overall
value
for
fishing
in
the
region.

Section
B5­
2
describes
the
Hicks
et
al.
(
1999)
model
and
the
resulting
estimated
coefficients.
Section
B5­
3
focuses
on
the
method
of
estimating
welfare
and
the
results
stemming
from
changes
in
catch
rates
as
a
result
of
eliminating
I&
E.
The
following
section
describes
the
data
set
used
in
the
analysis
and

results.

DATA
SUMMARY
The
Hicks
et
al.
(
1999)
analysis
of
improvements
in
recreational
fishing
opportunities
in
the
New
England
and
Mid­
Atlantic
region
relies
on
a
subset
of
the
National
Marine
Fisheries
Service's
(
NMFS)
Marine
Recreational
Fishery
Statistics
Survey
(
MRFSS),
combined
with
the
1994
Add­
on
MRFSS
Economic
Survey
(
NMFS,
1999;
QuanTech,
1998).

The
model
of
recreational
fishing
behavior
developed
in
the
study
relies
on
a
subset
of
the
survey
respondents
which
includes
only
single­
day
trips
to
sites
located
along
the
Atlantic
coast.
This
section
provides
a
summary
of
anglers'
characteristics
who
took
one­
day
trips
to
fishing
sites
in
the
five
North­
Atlantic
states.
This
analysis
is
based
a
sample
of
9,314
respondents
to
the
MRFSS
survey.

Recreational
Fishing
Choice
Sets
For
consistency
with
Hicks
et
al.
(
1999),
the
Agency
aggregated
NMFS
intercept
sites
to
the
county
level,
resulting
in
26
sites
from
Maine
through
Connecticut.
The
26
fishing
sites,
along
with
the
angler s
state
of
residence,
define
the
individual s
choice
set.
The
choice
set
is
defined
according
to
the
approach
developed
by
Hicks
et
al.
(
1999).
If
the
closest
site
is
within
30
miles
from
the
angler s
home,
then
all
sites
within
150
miles
are
assumed
to
be
in
their
choice
set;
otherwise,
all
sites
within
400
miles
are
assumed
to
be
in
their
choice
set.
Distances
in
the
original
study
were
estimated
using
PCMiler
software.
EPA
used
ArcView
3.2a
software
to
determine
the
distance
from
an
anglers
residence
to
each
NMFS
intercept
site.
Further
discussion
of
distance
estimation
is
presented
in
Section
B5­
1.4.
Based
on
this
method
of
site
choice
construction,
EPA
concluded
that
residents
of
the
five
states
have
4
to
26
fishing
sites
in
their
choice
sets.

B5­
1.3
Site
Attributes
This
analysis
assumes
that
the
angler
chooses
between
site
alternatives
by
comparing
his
indirect
utility
function
for
each
alternative
and
choosing
the
one
that
maximizes
his
utility.
Following
Hicks
et
al.
(
1999),
this
assumption
states
that
the
individual
first
chooses
fishing
mode
and
target
species
and
then,
conditional
on
his
choice,
chooses
the
recreational
site.

Catch
rate
is
the
most
important
attribute
of
a
fishing
site
from
the
angler s
perspective
(
McConnell
and
Strand,
1994;
Haab
et
al.,
2000).
This
attribute
is
also
a
policy
variable
of
concern
as
catch
rate
is
a
function
of
fish
abundance,
which
is
affected
by
fish
mortality
due
to
I&
E.
The
catch
rate
variable
in
the
model
provides
a
means
to
measure
baseline
losses
from
I&
E
and
changes
in
anglers 
welfare
attributed
to
changes
from
I&
E
due
to
the
316(
b)
rule.

To
specify
the
baseline
fishing
quality
of
the
case
study
sites
EPA
followed
the
approach
used
by
Hicks
et
al.
(
1999).
The
Agency
calculated
average
historic
catch
rates
based
on
the
NMFS
intercept
survey
data
from
1990
to
1994
for
recreationally
important
species,
such
as
striped
bass,
bluefish,
summer
flounder,
Atlantic
cod,
tautog,
and
winter
flounder
(
McConnell
and
Strand,
1994;
Hicks
et
al.,
1999).

EPA
aggregated
all
species
into
five
species
groups
 
big
game
fish,
bottom
fish,
flatfish,
small
game
fish,
and
no
target
 
and
calculated
the
average

historic
catch
rates.

the

definitions
in
Hicks
et

the

represent

both

the

The
Agency
assumed
that
the
welfare
gain
per
day
of
fishing
is
independent
of
the
fishing
mode
and
the
number
of
days
fished
per
trip
and
therefore
equivalent
for
all
modes
(
i.
e.,
private
or
rental
boat,
shore,
and
charter
boat)
for
both
single­
and
multiple­
day
trips.
The
model
developed
by
Hicks
et
al.
(
1999)
includes
the
fishing
mode
choice
as
well
as
the
targeted
species
group
choice.
Thus,
for
every
angler,
regardless
of
mode
or
species
choice,
changes
in
historic
catch
rates
for
a
particular
species
group
offer
a
gain
in
welfare.
Every
fishing
trip
taken
is
the
result
of
a
choice
decision
affected
by
the
changes
in
I&
E.
Therefore,
all
fishing
trips
taken
should
be
included
in
estimating
total
losses
from
I&
E.
