Fall and Herring

TAG is back in Cape Breton to take advantage of one of bluefin tuna's favorite meals...Clupea harengus, aka the Atlantic herring. Herring are a pelagic species which form schools particularly during feeding and spawning periods. In the southern Gulf of St. Lawrence, herring spawn in the spring and fall. Fall spawning occurs mainly from mid-August to October at depths of 5 to 20 m. Eggs are attached to the bottom and large females can produce up to 360,000 eggs. Herring eggs also attract another one of bluefin tuna's favorite meals...Scomber scombrus, aka the Atlantic mackerel. The mackerel are there to eat the herring eggs...and so you have an large amount of prey, which in turn attracts a large amount of predators...from bluefin to pilot whales to seals.

The bluefin are in the Gulf of St. Lawrence to fatten up on herring and mackerel before making their long migration back to the Gulf of Mexico (or Mediterranean) to spawn.

In the first two days back on the water we have had 16 hook-ups!! And so a busy couple of weeks begins...just need some good weather!!
