I googled Stetson Bank after I wrote the below heres one of several diving related links. Same place ??
Stetson Bank Trip - August 96
Did you mean Stetson Rock?
@ 75' it follows the outline I posted above.
Kings, Snapper, Grouper.
I've drift\jigged ,drift bottom fished and trolled the area
at different times of the year with success.
Here's some sample reports from Galveston by others.
Reports from Galveston for Stetson Rock
June time report,
Several wrecks and old coral outcroppings in 75' to 80' of water were fished. We were fishing Spanish Sardines fished at or near the bottom over a wreck in 75' of water and with in roughly 30 minutes, 39 sow red snapper from 14 to 21 pounds had been decked
March time report,
The first stop was at Stetson Rock which is about 72 miles to the SE. The 75 ft. deep water gave up 63 kingfish to a really nice 41 pounds by the time they left.
The Herald Bank also sits between Galveston and Sabine pass. It is also a well known area.
Although the natural bottom is pretty flat and bland in our area out to 100 miles.
It has been said this area might have the Best, Most, Greatest, (pick one) gathering of accidental artfical reefs in the world provided by our local energy industry.
Great days of fishing have been made for me from the Sabine Jetties
simply driven by sea conditions and fuel capacitiy. From Sabine heading towards the West Cameron blocks (areas set up and named by the oil guys)
There is always another platform on the horizon to check. Many of the platforms will have floating tye off bouy's the size of a small bus close by
that I try to troll (dolphin, wahoo) prior to setting up on a platform.
Now also their are wrecks, rocks, surmerged pilings and platform legs to be found and fished in the area also. But that would be another discovery phase of fishing our Texas and La. waters.
An area that I've yet to explore are a bunch of abandoned, sunken platforms moved to the High Island Block areas starting 70 miles from Galveston, these are part of the Texas reef program.
The moving targets that produce Tuna, Wahoo, Dolphin are the anchored Shrimp boats and weed lines. These are summer time possibilities and best
when the blue water comes within reach of ones boat.
So to try to answer the 2nd part of your question. I've personnely have never hooked a Tuna from over bottom structure in the Gulf. The closest in for me have been from behind deep water shrimpers. Yes even YFT, but that was father down the coast.
What area of the east coast are you x-fering from?
