ABSTRACT
This report presents the results of a 1980 survey in the Los Angeles
metropolitan area to assess the consumption rates of potentially hazardous
marine fish and shellfish by local, non-professional fishermen; to identify
population subgroups having a significantly large consumption rate; and to
estimate the size of the population potentially exposed to harmful pollutants.
The results of this study represent the first phase in the evaluation of the
potential hazard to humans by consumption of marine fish and shellfish from
polluted waters in the harbor and coastal regions of Cos Angeles County.

SECTION 1
INTRODUCTION
In 1978, the California Department of Fish and Game carried out a major
independent sportfishing survey in Southern California.1 The results of that
survey indicated that considerable fishing effort was expended (one million
angler-trip hours per year), that 75% of the catch was composed of 20 species,
and that one in three fish caught was a white croaker. White croaker has been
shown to contain large amounts of DDT (average = 39 pg/g)2'and polychlorinated
biphenyl (PCB). Concentrations of PCBs have been shown to range from 0.6 pg/g
within Los Angeles Harbor3 to 2.8 pg/g near the White Point sewage outfall.*
The survey a".so reported some catches of shellfish. Shellfish have been shown
to be contaminated with heavy metals as well as the carcinogen benzo(a)pyrene4
(BaP). No data were obtained, however, to demonstrate that direct consumption
of fish or shellfish occurred in this population of sportfishermen.
This report presents the results of a 1980 survey in the Los Angeles
metropolitan area to assess the consumption rates of potentially hazardous
marine fish and shellfish by local, non-professional fishermen; to identify
population subgroups having a significantly large consumption rate; and to
estimate the size of the population potentially exposed to harmful pollutants.
The results of this study represent the first phase in the evaluation of the
potential hazard to humans by consumption of marine fish and shellfish from
polluted waters in the harbor and coastal regions of Los Angeles County.

SECTION 2
MATERIALS AND METHODS
During the design period of October 1979 to December 1979, a question-
naire on sportfishing and catch consumption was designed based on several
pilot tests. The questionnaire (Appendix A) collected information on: (a)
demographic characteristics of the fishermen and their -family/1iving group;
(b) patterns of fishing activity; (c) species, numbers, and weights of fish
caught; and (d) characteristics of fish consumption in the family/living
group. Distinction was made between those fishermen who caugnt fish for
consumption and those who caught fish for other purposes. The final version
cf the questionnaire was designed for ease of coding and keypunching for
computer analysis.
LOCATION OF SURVEY SITES
During the design period, numerous fishing locations in the harbor and
coastal areas of Los Angeles were evaluated as possible survey sites. Twelve
representative locations were subsequently chosen for the survey. The
California Department of Fish and Game confirmed that these sites (Figures la
and lb) were frequently used and contained abundant marine life.5 In addi-
tion, they were affected by varying degrees of pollution.6 Two of the sites
(sites 7 and 8) were near sewage outfalls. The major Los Angeles County piers
were included in the survey (sites 1, 5, and 8-11). Party boats (sites 6 and
12) were included because many sportfishermen do not fish from piers, shore,
or breakwater areas. Fishermen utilizing private boats were excluded from
this study because their fishing sites were too random, ranging from areas of
pollution impact to Dristine waters, and covered too broad an area to be
surveyed adequately with the resources available.
SURVEYING PROCEDURES
Four surveyors visited each of the twelve sites, usually in teams of two.
Attempts were made to survey each site approximately three times/month on
different days of the week and different times of the day. The surveying
period was January 1 through December 31, 1980.
Surveyors were selected on the basis of their Southern California fishing
experience and their knowledge of marine life. Each team was composed of a
male and female. Surveyors were presented with appropriate identification.
When the surveyors arrived at a sampling site, they recorded in a logbook
the number of fishermen, their sex, race, and approximate age. All fishermen
were counted whether or not they had caught fish. However, only those fisher-
men with fish were subsequently interviewed. No fisherman was interviewed
2

-------
more than once during the one year study period. When the number of fishermen
with fish at the sampling site was greater than 20, a systematic sampling
approach was used (Appendix B).
Although it was not an essential part of the survey, attempts were made
to obtain names and addresses of interviewed sportfishermen so that fishermen
could be interviewed in more depth in subsequent research. As an incentive,
fishing maps, regulations, and/or recipes were mailed to them.
Surveyors interviewed the sportfishermen, identified and counted the
number of fish, and estimated the average weights using Ohaus Dial Spring
scales (Appendix B). Surveyors also coded the questionnaire for keypunching.
Photographs were taken frequently to assure the reliability of the surveyors'
taxonomic identification of fish, to document site conditions, and to confirm
sportfishermen counts.
DATA MANAGEMENT/STATISTICAL ANALYSIS
Questionnaires were submitted to the analyst/supervisor at biweekly
meetings and reviewed for accuracy, consistency, and completeness. Data from
questionnaires were keypunched and stored on computer disk, and analyses were
carried out using the SPSS computer package.7 Appendix C summarizes the codes
and coding procedures.
The daily consumption of each species (grams/day/person) was calculated
from the equation:
nw f
Consumption = k x ~ x
where k = edible portion (by weight) of fish (k < k < depending on species)
n = number of fish in catch
w = average weight (grams) of fish in catch
e = number of fish eaters in family/living group
f = frequency of fishing per year
Assumptions underlying this formula are that the number and average
weight of the fish represent a "typical" catch for a given fisherman, the
number of family fish eaters is constant over the study period, and the catch
is shared equally among family members.
From the questionnaire data, demographic characteristics, and fishing
activity of the sportfishermen, as well as average (median) consumption rates,
were determined. Differences in median consumption rates were compared across
sites and across demographic characteristics using the Kruskal-Wal1 is non-
3

-------
parametric analysis of variance procedure.8 The size of the sportfishermen
population was estimated from the logbook data. Details of the estimation
procedure are presented in the next section (Table 9).

SECTION 3
RESULTS
During the period of January 1 to December 31, 1980 a total of 1,059
interviews were conducted; 61$ during the week, 39% on the weekend. Nearly
two-thirds of the days were sunny, while the remainder were foggy, cloudy, or
raining. During January, mid-February, and March, heavy-rains reduced inter-
viewing. Heavy erosion and landslide conditions closed Abalone Cove (site 7)
from late March until November. Consequently, Point Vicente was substituted
as a survey site (see Figure la and lb).. In early spring, quarantines were
imposed for about ten days in Santa Monica Bay and Los Angeles/Long Beach
harbors due to heavy sewage overflow. During that period, interviews could
not be obtained. Also, Gerald Desmond bridge (site 3), which is not legally a
public access bridge, was closed in March and from mid-September to December.
Illegal disposal of chemicals caused closure of sites 9-11 from December 9 to
17.

Table 5 presents a summary by species of the percent of fishermen who
primarily consumed their fish or gave it away, the median amount of fish
consumed, and the primary methods of preparation. The majority of fishermen
interviewed supplemented their diet with the fish they caught, and the most
common method of preparation was pan frying. Although few fishermen primarily
ate raw fish, 8% said they ate it occasionally. Of the raw fish consumed, 16%
were white croaker, 32% were bonito, and 12% were Pacific mackerel. Other
uses of fish not shown in Table 5 included use as pet food and fertilizer.
Table 6 presents the cumulative distribution of total fish and shellfish
consumption. The median amount consumed was 37 g/day/person, with the 90th
percentile at 225 g/day/person (i.e., 10% of the fishermen consumed more than
this amount). These figures are based on total grams of edible fish in each
fisherman's catch regardless of species. Broken down by species, the
consumption rate will differ, i.e., Table 10.

Table 7 presents the median total fish consumption stratified by age,
race, site, and fishing season. The Kruskal-Wal1is analysis of variance test
indicated significantly larger consumption rates among senior citizens (65
years or older) and among the Oriental/Samoan subgroup (P < 0.001). Also,
significantly more fish were consumed from catches in site 8 (P < 0.001), a
site likely to be influenced by waste discharge.
Table 8 compares the demographic characteristics of frequent versus
infrequent fishermen. Chi-square tests of significance indicated that
frequent fishermen tended to be older, Caucasian, and lived either alone or in
a smaller family group.
Logbook data were used to estimate the size of the population of sport-
fishermen at each of the 10 sites excluding party boats. Party boats were not
included since no data were obtained on the number and size of all party boats
in the Los Angeles coastal area. Estimates were based on fishermen counts
obtained from the logbook data. Distinction was made between weekday and
weekend counts.
For each weekday (or weekend day) the recorded count in the logbook
represented the peak number of fishermen during the regular surveying hours.
Th-is count was an underestimate of the total number of fishermen at the survey
site for the entire day. The peak numbers were averaged over all site visits
to give 400 fishermen/day for all 10 sites on any weekday and 945 fishermen
per day for all 10 sites on any weekend day. These averages ere then adjusted
by weighting them by factors equal to the proportion of weekdays per year (=
261/365) and the number of weekend days per day (= 104/365). The weighted
averages were 286 fishermen per day for all 10 sites on a weighted average
weekend day. Thus, the average number of fishermen per day for any day was
286 + 269 = 555.

The average number of fishermen per day by frequency of fishing (Table
9a) was calculated by multiplying this total by the corresponding proportion
of fishermen given in the fishing frequency statistics presented in Table 3.
The total number of fishermen per year was obtained by multiplying the number
of fishermen (by frequency category) by the number of days per year and
dividing by a factor to account for the fact that the same fishermen were
sometimes being counted more than once. Therefore, this factor represents the
number of times that an individual fishermen is seen during the year. From
these assumptions it was determined that there were at least 31,351 different
sportfishermen per year at Lhe 10 sites. Using data on the distribution of
family fish eaters, the total number of people who eat fish caught by the
31,351 fishermen was estimated to be at least 100,950 (Table 9b).

SECTION 4
DISCUSSION
This report represents the results of a fish consumption study carried
out during 1980 to characterize sportfishermen and their catches in the
coastal regions of Los Angeles County. A total of 400 visits were made to 12
sites (Figure 1); 1,059 interviews were completed from an estimated sport-
fishing population of at least 31,351 (Table 9). The median consumption rate
was found to be 37 g/day--much higher than the average fish consumption for
the U.S. population as a whole (estimated at about 18.7 g/day).9 Although
shoreline fishermen are shown to consume fish at rates considerably above the
national average, it must be remembered that: (a) these data are biased
toward frequent fishermen since they are more likely to be interviewed at any
given time; (b) these data do not take into account consumption of store-
bought fish or dietary sources which might be displaced by eating locally
caught fish; and (c) the recorded catch may represent a fraction of the entire
catch.
The results of this study also show that there exists a regular fishing
population along the Southern California shoreline (14% fish 3 to 7 times/
week), even at sites likely to be influenced by waste discharges (sites 7 and
8). Fish caught by frequent as well as infrequent fishermen are generally
shared and consumed among at least 101,000 family members (Table 9).
The catches are dominated by a few species (Table 4) including two, white
croaker ana Pacific bonito, which accumulate trace organics including PCBs.
PCBs have long been shown to produce toxic effects in -prolonged industrial
exposure10-12 and affect children born to mothers exposed to oil contaminated
by PCB.13 They have also been found in the milk of nursing mothers in
Michigan.14
Table 10 shows the estimated 50th percentile (median) and 90th percentile
consumption levels of PCB for the edible portion of white croaker and Pacific
bonito. Data on PCB concentrations for bonito were obtained in 1975-77 by
trawl in the relative area of this survey.2 Data on PCB concentrations for
white croaker were recently reported by Young et al^.3 from fish taken in the
outer Los Angeles harbor region of Cabrillo Beach. Based on these data, which
may not be accurate for fish consumed in the present study, the annual median
level of PCBs for white croaker consumption would be 3.2 mg (14.8 g/day x 0.6
pg/g x 365 days). Similarly, the annual median level of PCBs for bonito
consumption would be 7.2 mg (63.6 g/day x 0.31 pg/g x 365 days). If one
considers the population of heavy fish eaters at the 90th percentile, the
annual consumption of PCBs would De 18.7 mg for white croaker and 37.8 mg for
bonito. However, calculation of daily dose (Table 10) at the 50th percentile
indicates a consumption below the permissible FDA guidelines of 1 pg/kg/day.
At the 90th percentile the calculated dose approaches this permissible level

for white croaker and exceeds the level by 0.48 pg/kg/day for bonito. It is
recognized that the 90th percentile population reportedly consumes high levels
of white croaker (85.2 g/day) and bonito (334.0 g/day) which is considerably
above the estimated national average. Although fishermen in the 90th
percentile reportedly consume large amounts of fish, there is reasonable
agreement between the consumption rate and the quantity of fish in their
catch.
Despite what is known about the toxicity of PCBs, it is not yet possible
to assign with any certainty a critical risk threshold. Therefore, the
long-range public health significance of PCB contamination in humans remains
unknown. We do feel, however, that sufficient data exist to warrant further
studies. In particular, analyses of the twelve most prevalent fish being
consumed should be undertaken to identify and quantify possible contaminants.
The effect of cooking methods on levels of contaminants should also be
examined. In addition, further work is needed to determine potential
subpopulations at risk such as raw fish consumers, individuals over 65 years,
Orientals and Samoans, and frequent fishermen at site 8 (Table 7). In-depth
health assessments of these subpopulations must then be carried out.

APPENDIX B1
INSTRUCTIONS TO SURVEYORS
Survey Method
Rules in conducting the interview.
1.	Interview people only once. Methods of avoiding repetition:
(a)	by recognition
(b)	If no recognition, then ask:
(i) Have you been interviewed for the "U.S.C. Fish Usage
Survey" before?
(i i) If YES, ask when.
If before January 1, 1980, then proceed with the
interview.
If after January 1, 1981, then S~0P.
If they agree to the interview, then give the individual the Surveyor's
business card, thanking him/her for participating in this "U.S.C. Fish
Usage Survey." The handling out of the I.D. card will identify this
particular survey.
2.	Do not interview anyone without any fish caught. Go back to
that individual later.
Sample Size
Count the number of fishermen at time of entry. Fill in
the log form. Break a day into two sections as morning
and afternoon.
(a)	If the number of fishermen is equal to or less than
twenty, then proceed to interview them all.
(b)	If number is 20 - 40, then interview every other one.
(c)	If number is 40 - 60, then interview every third one.
(d)	If number is 60 - 80, then interview every fourth one.
Random Sampling
By flipping coin to
(a) designate a type (either A or B)
(i)	If "head" turns up, then
Surveyor with odd number,
i.e., #1 or #3 = A
(ii)	If "tail" turns up, then
Surveyor with odd number = B
(b) Choose a pattern
(i) If "head" turns up, then use this pattern:
Pick a land mark as the approximate middle.
Surveyor with even
number, i.e., #2
or #4 = B
Surveyor with even
number = A
A
B

-------
APPENDIX B2
(ii) If "tail" turns up, A starts at one end, B starts at
middle, and both go in the same direction.
B. Method for Filling Out Questionnaire
Location: (Refer to the hand out maps). The choice sites are:
1.
Belmont Beach Pier
2.
Queen Mary
3.
Gerald Desmond Bidge
4.
Navy Mole
5.
Cabrillo Beach
6.
Party Boat
7.
Point Fermin, White Point, Abalone Cove
8.
Redondo Beach, Hermosa Beach, Manhattan Beach
9.
Marina Del Rey
10.
Venice
11.
Santa Monica
12.
Party Boat
Weather condition:
Determine by the condition at the time when the interview begins.
Temperature:
Determine by the readings indicated on the thermometer. Each
surveyor should bring along a thermometer.
Tide:
If a distinction of whether high or low tide cannot be made, use the
additional choices of waxing—water conditions approaching high
tide, and waning--water conditions approaching low tide.
Time of interview:
Determine by the use of a watch, recording hours and minutes.
Subject number:
Assign each interviewee a number starting the first one with number
1 so on numerically. A number list is provided to each surveyor to
aid him/her in remembering the last person he/she interviewed. Just
make sure to cross off each number for each interview made.
Occupation:
Try to single out retiree and minor. If column 2 is filled, then
follow up with questions on occupations. The key word is primary--
any job that is held for a duration of at least a year. The phrase
"doing other things" means the person is not formally employed at
this moment.
Do you generally fish in the area?
"Area" refers to the location that is being interviewed at. Substi-
tute the name of the location for area where the question is asked.
Subject number:
Should match the same number as assigned on page 1.
23

-------
APPENDIX B3
Type of fish/shellfish:
Refers to one type of fish/shellfish--to be recorGed in each column.
Thus, two types of fish/shellfish can be recorded on a page. Addi-
tional types of fish/shellfish have to be recorded on second page.
How many:
Actual count of type of fish/shel1fish being caught.
List average weight:
Determine by the use of a scale. If amount of fish/shellfish is ^3,
weigh all, then take the average. If type of fish/shellfish caught
is >3, weigh any random 3 and take the average.
Primary usage:
If an interviewee gave more than one answer, then try to prompt
him/her to furnish more information so that a decision can be made
as to answer the key question of "What happens to the majority of
this type of fish/shellfish?"
If eaten, method of cooking:
If two answers are given, then prompt him/her to tell which is
his/her favorite way of cooking this particular type of fish/
shellfish.
