Consumption rates of anglers fishing in summer and 

 nonsummer months did not differ significantly 

 (Mann-Whitney rank sum test; T=72,857; «(small)= 

 260; ra(large)=295; P=0.7597). Median consumption 

 rates were 21 g/day for both groups (Table 4). 



Median consumption rates of the most commonly 

 caught species were similar (11-16 g/day) but up- 

 per-decile rates were more variable (27-80 g/day) 

 (Table 5). Some individuals greatly exceeded aver- 

 age consumption rates for chub mackerel (Fig. 5). 

 Median consumption rates were highest (16 g/day) 

 for barred sand bass, kelp bass, combined rockfish 

 species iSebastes spp.), Pacific bonito, Pacific barra- 

 cuda, and California halibut (Table 5). Upper-decile 

 consumption rates were highest for kelp bass, barred 

 sand bass, and combined rockfishes (80, 78, and 63 

 g/day, respectively). Rates of consumption of specific 

 species varied by ethnic group (Table 5 ). Species with 

 highest median and upper-decile consumption rates, 

 respectively, by ethnic group were as follows: jack- 

 smelt, Atherinopsis californiensis, and barred sand 

 bass (white); barred sand bass and chub mackerel 

 (Hispanic); rockfishes and chub mackerel (Asian); 

 and Pacific bonito and California halibut (black). 



Consumption rates estimated by the fillet-model 

 and by the consumable-portion methods did not dif-
