were market squid ( Loligo opalescens , 39% of catch). Pacific hake 
( Merluccius productus , 10% of catch), Pacific tomcod ( Microgadus proximus , 
5% of catch), walleye pollock ( Theragra chalcogramma ,4.9% of catch), and 
Pacific cod ( Gadus macrocephalus , 3.3% of catch). Overwhelmingly, the 
fishermen planned to consume only the fillet (93.2%). The most common 
modes of preparation were frying (53.2%), baking (16.8%), and boiling (11.1%). 
The average boating angler was an employed (68.8%) male (95.9%) with 12 or 
more years of education (91.4%). Most were Caucasian (86.1%); however, 
black (3.8%) and Asian (8.3%) fishermen were encountered regularly. The 
anglers ranged widely in age, with a large percentage falling in the 
19-39 year (59.9%) and 40-59 year (27.8%) age brackets. Boating anglers 
fished predominantly on weekends (95.9%) and were most active between the 
hours of noon to 6:00 p.m. (66.8%). Although fishing activity occured 
year round, it peaked during the Summer (56.8%). Only 37.1% of the anglers 
caught no fish. Among those catching fish, most (72%) landed fewer than 
five per trip. The five most commonly caught species (based on numbers of 
organisms) were walleye pollock ( 29.8% of catch). Pacific cod (15.5% of 
catch), flatfish (mixed species, 12.7% of catch), rockfish (mixed species, 
7.5% of catch), and coho salmon ( Oncorhynchus kisutch , 7.0% of catch). Use 
of the term "mixed species" indicates that the fish had already been 
skinned and filleted at the time the interview was conducted, and that they 
could not be identified to species. The vast majority of fishermen (98.9%) 
planned to eat only the fillets. The most common methods of preparation 
were frying (41.5%), barbecuing (27.3%) and baking (18%). 
Trace metals analysis in raw fish . The mean, range and standard deviation 
of all trace metal measurements are summarized in Table 1. For the purpose 
of mean calculation, the "less than" values are considered as real values. 
For example, if the concentration of As was <0.001 mg/g, the value of 
0.001 mg/g was used for the mean calculation. Also, the numerical values 
of non-detectable results were set to equal zero (ND=0) for the mean 
calcualtion. 
The summary results in Table 1 show that the mean concentration of Hg, Cd, 
Pb, and Se in all of the groups fluctuated within a narrow range, and that 
the mean values were almost comparable within the standard deviation of the 
measurements. The Zn and Cu mean values of the different fish species 
also showed comparable values; however, squid showed clearly higher 
levels of Cu and Zn than did the fish samples. Rock sole showed almost 
twice as much As as did starry flounder (3.3 +/- 0.7 mg/g and 1.5 +/- 
0.7 mg/g, respectively). Pacific cod and walleye pollock, both migratory 
species, showed As values (4.4 +/- 2.9 mg/g and 4.6 +/- 4.1 mg/g, 
respectively) that were comparable to those of the non-migratory rock sole. 
Trace metals analysis in cooked fish . The concentrations of trace metals 
in fried fish (FF) and raw fish (RF) in nine samples are compared in Table 2. 
The concentrations of trace metals in fried fish were normalized to the 
weight of raw fish, and then the ratio of metals in fried fish/raw fish 
were calculated. For the ratio calculations, "less than" or "more than"
