Capt. Steve Nagiewicz of Brick has come out with a book, Hidden History of Maritime New Jersey, that should be in every angler's bookcase. That veteran professional diver and skipper of diving charter boats details the stories behind most of the shipwrecks anglers either have fished or heard about over the years, including the often tragic loss of life that finally resulted in establishment of lifesaving stations along the Shore that was described in 1854 as "treacherous, with constantly changing sandbars, uninhabited shores and little in the way of organized lifesaving" as the New Era with immigrants from Germany was broken up in a storm off Deal with the loss of 295 persons -- though 135 survived.  There's one fascinating account after another, including that of Black Sunday (June 2, 1917) when the German sub U-151 sunk six ships and created what we now know as the Triple Wrecks area where a fleet has been targeting bluefin and yellowfin tuna this week. Nagliewicz even has a chapter on the famous shark attacks that occurred from Beach Haven to Matawan Creek starting July 1, 1916. The well-illustrated black and white 176-page paperback is published by The History Press (www.historypress.net).  It lists for $21.99. Though there were quite a few 50-to-60-pound bluefin and yellowfin tuna caught at the Triple Wrecks on Wednesday, the fleet was greeted on Thursday by bluefish. Capt. Chris Di Stefano of Wall was aboard Frank Criscola's Crisdel from Brielle Yacht Club as they found the good water that had attracted tuna was gone. A day of trolling produced only one of each species at about 25 pounds while blues as small as 3 pounds mauled the balao baits. It's that time of year when odd ball species start showing up in our very warm waters. I didn't get to see the strangest, but an angler showed Joe Melillo at Castaways Tackle in Point Pleasant a cell phone picture of a fish he'd plugged at Bay Head which had to be a cutlessfish by the description of its flatish silvery sides and a narrow mouth full of sharp teeth. I caught lots of those strange fish while fishing at night off the piers at the U.S. Naval Station in Trinidad when I was a Navy officer many years ago. They are also the object of offshore night bottom fisheries in many tropical countries.  Don Marantz noted that Paul Haertel of Toms River was on his way back to Barnegat Inlet on Wednesday when he came upon a school of sharks that he identified as blacktips. Those sharks are commonly sighted in great numbers off Florida's east coast, but rarely found this far north. Haertel hooked one to try to get a photo, but was alone and couldn't control it. Talking about hooking strange sharks, fluke pro Dave Lilly of Hazlet did that while hosting Mark Capalbo of the Salt Water Anglers of Bergen County. They were fishing Wednesday outside the bay in schools of bunkers and watching whales while picking at fluke when Lilly spotted a thresher. He cast a jig tipped with Gulp at it, and was shocked when the shark engulfed it. Fortunately, the 200-pounder bit through the leader before Lilly spent all day fighting it on light tackle. Fluking has been up-and-down in Raritan Bay, but it was just fine Monday for Capt. Stan Zagleski on Elaine B. from Bahrs in Highlands. Tom Hollywood Jr. of Staten Island boated his second career doormat with a 10 1/2-pounder that was also the boat's sixth this season. Frank Lavelle of Hoboken had four keepers up to 9 7/16 pounds. Tank Matraxia of Lyndhurst fished aboard the Capt. John from Keyport on Thursday, but watched most of the keepers, including an 8-pounder) come up on the other side of the boat during a long drift in Raritan Reach. When he finally hooked a keeper, it was snagged both by him and Emil Pavelac. The party boat standard for determining the owner of a fish that takes two hooks is the one that's deepest, but I don't know what the standard is when two anglers snag the same fish. Capt. Ron Santee reported anglers on his Fishermen from Atlantic Highlands had up to four fluke on Thursday, with a pool winner of 7 pounds. Ron Santee Sr. boated a 6.5-pound fluke. The fluke tournament season kicks off on July 16-17 with the two-day Sandy Hook Bay Anglers Club Tournament at Atlantic Highlands, and the July 16 Raritan Bay Anglers Fluke Tournament at Perth Amboy.

The Gambler from Point Pleasant has been catching them up to 6 1/2 pounds plus sea bass up to 3 pounds. Last Sunday's shark trip with 15 anglers only produced one missed rrun-off, but they're going to try again this Sunday. Bluefishing inshore has been spotty, but chub mackerel have shown up again in the ocean to provide some action for party boats. The Queen Mary from Point Pleasant has been catching plenty of them plus a few blues -- and even sharks up to six feet.
