Daily Fishing and Outdoor Report

 

Wednesday, May 23, 2012: If you’re a saltwater angler on the mainland right now – noon – you’ll surely be champing at the bit. The skies have been burnt clean -- into a blue like we haven’t seen in awhile. What’s more, the sun beat down has already pushed mainland temps well past the predicted high. It’s into the 80s.

 

And if you’re contriving any way possible to get over here to fish the LBI area, you’re kinda on the right track. That said, I’m going to go off the forecast by putting a little warning out there. What do you get when you cross hot air temps and cool ocean temps. Clam chowder. Nope. Fog. And it’s really one of those days where you could be shoulder deep in sky perfection, see an odd grayness on the horizon and find yourself spookily  trying to bump back in. Electronics are powerful tools but so is one’s imagination when peering into the mysterious zero visibility realm. 

 

That warning given, there are fish hanging about. A few bass can be found along the LBI beachfront but way are lounging in the ocean off Seaside (and slightly south). That, in fact, is why I give that fog alert. It’ll be sorely tempting to do a long rush northward  to confirm tales of 40-pounders.

 

It sure seems the bunker-related cow action that was closer to LBI last year decided to edge more to Sandy Hook and the Raritan zone this year.

 

Locally, odds are pretty good you’ll find some of the best fluke fishing this spring --  particularly in all the suspect spots associated with west-to-east Double and Oyster creeks. As for the more sizeable fluke – though not as plentiful – think Little Egg and even over toward Grassy and down toward Sandy. Around the inlets, you have to be totally tuned into tide changes (mainly dead low rising) to find the sweet spot, loaded with feeding flatties. That spot can move very quickly bayward, losing its distinction by the sedges.

 

As always happens when someone catches a big sheepshead (See Jingles B&T website), I get emails asking where to catch them and how. Unfortunately, there is no “where and how” if seeking this locally rare fish. What’s more, the odds of you getting one in the surf, like the five-pounder taken last week, are less than slim and none -- the proverbial  needle in a one-in-a-million haystack. 

As I’ve written, I’ve seen, while snorkeling, a scattering of sheepshead around the pilings of the Big Bridge, where a large one was caught earlier this spring and from where the NJ state record sheepshead hales.

And the bridge hang-out thing makes utter sense. In the land of fanatical sheepshead fishing, central Florida, virtually all sheepsheading is done from atop bridges, using mainly small crabs as bait. They are fished identically to tog. There are Floridian bridge tops where fights break out over spots, the prime locales being directly above pilings.

It is not out of the question that any migratory sheepsheads we see do their overwintering in the deep south -- and surely rule the pilings. When they go on summer sojourns, they surely seek out summering sites that have a familiar look to them.

By the by, when an angler catches even a massive two-pound sheepshead in Florida, it’s the talk of all the bridge tops. If anyone in Florida ever hooked into a 17-pounder (the NJ state record, Manahawkin Bay, 2003), it would most likely send everyone atop the bridge running onto the nearby highway in sheer terror.

 

Hey, better get signin’ up for the 2011 Simply Bassin’ tourney. The money is really up for grabs, with only eight or nine fish entered to date. There are still many weeks to go in this spring event fro bragging rights.

New fish-tagging studies of young bluefin tuna in Atlantic waters off New England by researchers at the University of Massachusetts Amherst are offering the first fishery-independent, year-round data on dispersal patterns and habitat use for the popular game fish. The availability of miniaturized pop-up satellite tags suitable for smaller (two- to five-year-old) fish helped make the research possible.Fisheries oceanographer Molly Lutcavage and lead author Benjamin Galuardi say the work shows that scientists now have tools to directly observe bluefin tuna annual migration patterns and vertical habitat use (depth) in the Atlantic and Mediterranean oceans in detail not possible in earlier studies. This new information should lead to better understanding of bluefin tuna ecology, catch patterns and management of wild stocks that provide a multi-million dollar sport fishery from Maine to North Carolina.

Lutcavage, director of UMass Amherst's Marine Research Station and the Large Pelagics Research Center (LPRC) in Gloucester, says, "Our tagging data are important because for the first time we've got direct measurements of bluefin tuna movements and habitat associations. In other words, their travel routes, depth and temperature patterns, and where they intersect with recreational fisheries."

Galuardi, an LPRC scientist and doctoral candidate in the Graduate School of Marine Science at UMass Dartmouth, led the analysis of data returned from pop-up satellite tags used in this study, as well as oceanographic conditions across bluefin migration paths. Details are reported in A recent issue of the Public Library of Science One (PLoS One) journal.

"Knowing the dispersal patterns of these young fish after they leave their nursery grounds and learning their year-round habitat needs are important goals for the commercial fishery of adult bluefin tuna, as well," she adds. For example, these tunas' winter and spring movements and behavior of juveniles have largely been unknown until now.

For this study, Lutcavage, Galuardi and fishermen partners deployed 58 miniature pop-up satellite archival tags (PSAT) and 132 implanted archival tags on juvenile Atlantic bluefin tuna between 2005 and 2009. Because only one archival tag was retrieved, data reported are mainly from 26 PSATs.

To deploy the PSATs, fish were caught by hook and line and brought aboard the boat to attach a miniaturized PSAT to the fish's fin by a tether and dart anchored at the base of the fin. These were programmed to record external temperature, depth and daily position based on light sensor readings every 15 minutes and to release after 12 months. Later models also recorded light level. Once at the surface, the PSAT tags transmitted the collected data to receivers on earth-orbiting satellites. The data were then transmitted to the researchers, allowing scientists to trace the fish's journeys and habitat over the previous year.

The authors report that all tagged bluefin tuna remained in the northwest Atlantic for the duration observed, and, in summer months they stayed in coastal waters from Maryland to Cape Cod out to the continental shelf. In the winter, they wandered more widely, exiting the Gulf of Maine and ranging south to the South Atlantic Bight (North Carolina to Florida), the northern Bahamas and the Gulf Stream edge.

Lutcavage and Galuardi found that vertical habitat patterns showed juvenile bluefin primarily occupied shallow depths, averaging about 16 to 40 feet (5 to 12 meters) and relatively warm water, averaging 64 to 70 degrees F (about 18 to 21 degrees C). In winter, they frequented deeper water and showed more variable depth patterns.

"These findings are the first long-term view into a year in the life of a juvenile bluefin tuna in the western Atlantic," Lutcavage notes. "The geographic and vertical concentration of summer habitat had been suspected due to patterns in the recreational fishery, but was not confirmed until this study. In addition, little information existed on what these fish did in winter months when the fishery does not operate. This information provides a window into what areas and conditions are important for growth and survival of juvenile bluefin tuna."

The authors add, "Our tagging results reveal annual dispersal patterns, behavior and oceanographic associations of juvenile Atlantic bluefin tuna that were only surmised in earlier studies. Fishery independent profiling from electronic tagging also provides spatially and temporally explicit information for evaluating dispersal rates, population structure and fisheries catch patterns and supports development of direct assessments."
