Back in the day my buddy and I used to do some serious chunking in the canal. Beginning as soon as the fish arrived in May, right through Oct. Herring in the spring, pogies the rest of the year. We'd buy about 1200 fresh herring each spring from the town of Wareham, individually freeze them, then pack them 6 to a bag. Each morning we'd bring 2 bags of herring to be used as chum. Chopping them into fine pieces on our board then throwing them into the rip a few pieces at a time. We'd often get the fish feeding on the chum like trout at a hatchery. However, when we began incorporating pogy oil into our chum the results jumped dramatically. Chop up several herring then add couple teaspoons of oil to the gurry. There were times we had 20 pounders following the chum/oil slick right to our feet looking for the source.
