Before you brag to your fishing pals about the 20-pounder you caught on 12-pound line, check out these line-class current world records from the archives of the International Game Fish Association. I’ve ordered them per the ratio of fish weight to line weight (strength). (For example, a 48-pound fish landed on line testing in the 8-pound class would be a 6-to-1 catch — and while impressive, not impressive enough to make this list.) The ratios are rounded off to the nearest whole number, by the way. Some fight times are crazy-short, but every record application warrants that catches were taken within the constraints of IGFA rules.
