Fork length–total length conversions for haddock Melanogrammus aeglefinus from Georges Bank and pollock Pollachius virens from the Gulf of Maine were developed by linear regression with data from fish caught during gear comparison studies. These conversions were developed to replace previous conversions that were inaccurate or insufficiently documented. Total lengths (TLs) and fork lengths (FLs) were obtained from 216 haddock ranging from 35 to 73 cm TL (median = 57 cm) and 220 pollock ranging from 43 to 107 cm TL (median = 75 cm). The conversion equation for haddock was FL = 0.95 × TL + 0.65. For pollock, it was FL = 0.94 × TL − 0.62. Reciprocal equations were also determined.
