Allen et al.: Seafood consumption rates among recreational anglers 



603 



of 21 g/day and an upper-decile rate of 107 g/day 

 (Table 4). Thus about 10% of the anglers had con- 

 sumption rates more than five times the median ( Fig. 

 4; Table 4). 



Consumption rate distributions for ethnic and in- 

 come groups were also strongly right-skewed. Me- 

 dian consumption rates for ethnic groups ranged from 

 16 g/day (Hispanics) to 24 g/day (blacks) (Table 4). 

 Although median consumption rates among ethnic 

 groups were not homogeneous (Kruskal-Wallis; 

 #=10.759; df=3; P=0.0131), none differed signifi- 

 cantly from each other (Dunn's method). Upper-decile 

 consumption rates ranged from 64 g/day (Hispanics) 

 to 137 g/day (Asians) (Table 4). Although anglers with 

 annual household incomes less than $5,000 had 

 higher median consumption rates (Table 4), these did 

 not differ significantly from the others (Kruskal- 

 Wallis; #=1.776; df = 4; P=0.7768). Upper-decile con- 

 sumption rates by income group ranged from 48 g/day 

 ($5,000-$ 10,000) to 129 g/day (>$50,000) (Table 4).
