05 May 2014 Hudson Canyon to Hydrographer Canyon Analysis – Good Fishing Action Awaits Offshore


Based on a multiple factor analysis, the symbols (hot spot dots) mark the areas where bait concentrations are expected and where fishing action are expected to be better compared with other (non-marked) areas. These are not based on dock rumors or hearsay fishing reports. Fishing reports are stated as such. You should start fishing where you recognize other signs of good fishing conditions near these marked areas. It is very important to use your sea surface temperature (sst°) gauge to locate the boundaries of the water masses, which are outlined. Rather than trying to find water based on the absolute temperature values shown on the map, search for the relative change in sst° where the water mass boundaries occur. Arrows indicate the main current direction. Numbers inside of the dots indicate the number of consecutive days that we have seen favorable conditions in that location. Bottom depths in fathoms (1 fathom = approximately 6 feet).

We were able to see this area clearly today to increase your chances for mainly tuna (bluefin, bigeye and yellowfin tuna), sharks and swordfish action. Overall, there is a large clockwise rotation eddy east of Hudson Canyon containing 65.5°F to 67.1°F to 69.0°F water and also pulling this bluer mixed Gulf Stream water into the 1000 fathom ledges east of Toms Canyon and into the 500-1000 fathom ledges of Hudson Canyon as we expect the conditions to improve for fishing action as this eddy pushes warmer 65.0°F to 67.0°F to 69.0°F water farther into Hudson Canyon to Toms Canyon later this week. There is a clockwise rotating eddy centered over Block Canyon area pulling blended blue 65°F to 67°F water farther north of Block Canyon into the Fish Tails for favorable fishing action. Farther east there is 65°F-67°F- 69°F blue-green to blended blue water in the Atlantis Canyons and as far inshore as 50-60 fathoms in places north of the Atlantis Canyons.  There is also 65°F-69°F to 70°F bluer water into the 100 fathom ledges of Hydrographer Canyon to Veatch Canyon for some of the better chances at tuna action in this area. Of note, there is direct Gulf Stream water located farther east over the 1100-1200 fathom depths south of Oceanographer to Lydonia Canyon so the dolphin, wahoo and billfish are not far away and could be found in the 70°F-71°F water shown in this eastern charted area. Bottom line is once there is a window of a day or two of good weather there are several favorable options for good fishing action offshore for tuna and you will want to be ready and have your boat in the water ready to go offshore.

In the west, some of the better conditions for tuna action will occur over Hudson Canyon and northeast along the 500-1000 fathom ledges where it has been favorable for at least two days along the strong green to blue-green 50°F/52°F to 66°F/67°F to 69°F water mass boundaries from the 500 fathom mouth of Hudson Canyon (near 72°02-08’W & 39°21-23’N extending northeast over Jones Valley (near 71°55’W & 39°28-29’N to near 71°40’W & 39°30-37’N).  However, you may first want to fish the Fish Tails and northeast where there is blended blue 65°F to 67°F water against the blue-green 50°/52°F water for good tuna conditions near 71°20’W & 40°03-04’N extending northeast to the 60-70 fathom ledges near 71°08-09’W & 40°13-14’N all the way east along the 70 fathom ledges to north over the 50 fathom ledges near 70°55’W & 40°24-25’N. However, the 90-100 fathom ledges also look favorable as the relatively warmer 63°F-65°F water is pushing in a favorable inshore direction between West Atlantis Canyon (70°25-30-35’W & 40°05’N) west along the 100 fathom ledges to north of Brick Rock (near 70°50’W – 71°02’W & 40°05-06’N) and as far east as the 100 fathom ledges of Atlantis Canyon (near 70°10’W & 40°06-07’N).  Farther north you will increase your chances for tuna action along the strong blue-green to bluer 56°F/60°F to 65°F/67°F water mass boundary north of Atlantis Canyons where it has been favorable for two days over the 50-60-65 fathom ledges near 70°31’W & 40°12-13’N northeast to near 70°15-25’W & 40°17-18’N.

Fishing the eastern charted area, some of the better conditions for fishing action occur over the 50-60-70 to 100 fathom ledges of East Atlantis to Veatch where the bluer and warmer 65°F-67°F to 69°F/70°F water is pushing in a favorable inshore direction from near 69°54-59’W & 40°06-08’N to near 69°40’W & 40°08’N south to Veatch Canyon near 69°35’W & 40°00-01’N. Farther north and east, conditions also look favorable for tuna where it has been good for two days over the 45-50 fathom ledges north of Veatch Canyon where it has been good for two days near 69°30-35’W & 40°13’N and northwest to near 69°40-55’W & 40°20-25’N.  Farther east equally as favorable conditions will occur over Hydrographer Canyon’s 100 fathom ledges along the 60°F/61°F to 65°F to 70°F water mass boundary favorable for two days near 69°00-05’W & 40°10-12’N to near 69°15-20’W & 40°14-15’N and if that does not produce fish south along the 80-100 to 500 fathom ledges between Veatch and Hydrographer Canyon in the bluer 69°F to 70°F water.
