View locations our oceanographers recommend for finding specific types of game fish, based on data-driven analysis. The locations are overlaid on your chart and can be viewed in combination with other features.
Updated twice per week on Tuesday and Friday mornings.
What does this mean for you?
This tailored information helps you find the type of game fish you’re looking for, faster. You can view recommendations combined with other Fish Mapping features on your multi-function display to help you zero in on where you want to fish.
Color coded areas are recommended fishing locations by species.
View concentrations of floating algae/plants.
Updated every 24 hours.
What does this mean for you?
Floating algae/plants provide nutrients and cover, creating habitats for bait fish, shrimp, etc., and attract larger, predatory game fish. Weed lines drift and shift over time, so they can be hard to locate. Use this feature to help find where weed lines have been sighted recently, or are most likely to be forming – to help you find game fish.
Purple lines and circles represent where weed lines have been spotted recently or are most likely to be forming.
View locations where the sea surface height is noticeably different than the surrounding area. Our experts identify these spots using real-time radar data and models of the sea surface.
Updated every 24 hours.
What does this mean for you?
Locate “upwelling” areas that create favorable conditions including nutrient-rich water that attracts baitfish and game fish. You can also use this to avoid “downwelling” areas that are nutrient-poor and don’t support favorable fishing conditions.
Yellow lines represent sea surface height upwelling and downwelling locations.
View contour lines where sea surface temperatures are clearly illustrated.
Updated every 3 hours.
What does this mean for you?
Simplified contour lines quickly show the water temperatures in your selected area. Use these contours to help locate your target species based on their preferred temperature range.
Red lines represent the sea surface temperature contours.
View estimated strength of ocean fronts, which are significant temperature changes that create distinct boundaries between bodies of water.
Updated every 24 hours.
What does this mean for you?
Steep temperature changes or “fronts” concentrate nutrients which attract bait fish and also create barriers to fish movement. The location of strong and very strong fronts are good places to find game fish. At locations where both the temperature and plankton fronts coincide, there tends to be better fishing.
Red lines represent the estimated strength of temperature fronts.
View the water temperature 30 meters below the surface.
Updated every 24 hours.
What does this mean for you?
Different species of fish prefer specific ranges of temperatures. This feature allows you to identify areas with the preferred temperature range of your target game fish in the area below the surface where they are likely to be hunting.
Red lines represent the water temperature 30m below the surface.
View areas of plankton concentrations.
Updated every 24 hours.
What does this mean for you?
Plankton is the primary food source for most bait fish, which attract hungry game fish. You can view this on your multi-function display to identify favorable conditions for your target fish.
Green lines represent the plankton concentrations.
View areas with strong plankton concentration bordering areas with relatively little or no plankton.
Updated every 24 hours.
What does this mean for you?
Plankton fronts illustrate areas preferable to game fish. Strong plankton fronts indicate where nutrient-rich water favorable for bait fish occurs next to clear, predator-preferred water. In locations where both the plankton and temperature fronts coincide, there tends to be better fishing.
Green lines represent the strength of plankton fronts.

While dolphinfish, also known as mahi-mahi, are one of the most common game fish caught in the Atlantic Ocean, very little is known about the migration and overall health of the species.
The DRP is the world's largest public tagging system for dolphinfish. Since 2002, the DRP has worked with anglers around the world to tag and release dolphinfish. This data has enabled the DRP to chart the migratory nature of dolphinfish throughout the Atlantic Ocean – critical information necessary to improve dolphinfish management and ensure conservation of the species.
To support DRP and join other anglers who are tagging dolphinfish to improve our knowledge of their life history, movements, and population dynamics, request a free tagging kit at the link below. Whether you hit your daily limit or not on dolphin, if you find small fish consider tagging some for conservation.
