We grouped occupations into the following categories: fishing, selling marine products, tourism, farming, cash crops, gleaning, salaried employment, the informal sector, other, and 'none'none
Fish frequency data were grouped into three categories: no fish consumed, fish consumed one or two times, and fish consumed three or more times during the past 30 days.
The "other" categories of fish included fish products/fish in crumbs and nonspecific or combined fish, which formed a minor part of intake (intake of "other" categories constitutes <11.4% of combined fish and shellfish intake in the subcohort) or had limited availability in some countries.
We grouped juvenile detections at Lower Snake River dams into three categories: (i) fish detected between June and August, (ii) fish detected in September and October (most detection facilities at dams ceased operation by the end of October) and (iii) fish detected the following spring.
You want some from each of three broad categories: meaty fish (such as swordfish, albacore, shark or monkfish), flaky fish (sea bass, rockfish, halibut or lingcod) and shellfish (shrimp, clams, mussels, spiny lobster or crab).
These bins also roughly corresponded with age in autumn, although there is considerable overlap in age categories for fish larger than 115 mm.
The present risk/benefit analysis allows us to tentatively classify these species into categories of fish consumption.
The questions concerned how much and what categories of fish (canned tuna, dark meat, light meat, shellfish) the women ate.
