CRD 03-14 Table 12. Discard rates (kg/day fished) by fishing zone¹ obtained from a ratio estimator (kg of witch flounder discarded to days fished) using Fisheries Observer Program data collected from the northern shrimp fishery, number of days fished by the shrimp fishery, mean discard rates (kg/df) and estimated discard weight (kg) of witch flounder in the northern shrimp fishery, during the 1989-1997 shrimp seasons.
