The importance of oceanographic data for fishing

Sea surface currents, temperature, chlorophyll concentration and altimetry provide essential data for efficient and productive fishing and a better understanding of the behavior of fish (pelagic fish in particular) and better target fishing zones.

Sea Surface Temperature

MaxSea TimeZero Plot - Sea surface temperature

MaxSea TimeZero Plot offers an accurate, detailed display of the surface temperature, obtained via satellite. Each new version of MaxSea offers data that is increasingly global and more and more accurate.
The most important point is to clearly identify “rupture zones”, or in other words, thermal fronts where masses of water of different temperatures converge (in this image, a red zone, which is hotter, is encountering a yellow zone, which is colder). Fronts are likely to shelter more bait fish and therefore fish (mainly pelagic fish).

MaxSea TimeZero allows the selective display of a specific range of sea surface temperature, when targeting specific conditions.


MaxSea TimeZero Plot - Altimetry

Altimetry is an anomaly in the surface water height, in relation to a referenced mean sea surface height. These surface height measurements indicate the below surface temperature of water columns which change less quickly than the surface temperature.

The warmer the water is, the more the anomaly will be “positive” (higher than the referenced mean surface height) and vice versa.

The altimetry is obtained by radar detection. Unlike the surface temperature, sensing it is not susceptible to the presence of clouds. It therefore provides efficient information supplemental to the surface temperature. Here too, the zones where masses of warm water and cold water converge are the most interesting.

Thanks to MaxSea it is easy to use graphical display, it is easy to determine potentially fruitful fishing zones.

The fronts between warm and cold zones (between positive and negative anomalies) are zones where pelagic fish and particularly tuna are more likely to be present.

Surface current

Indicating rising water and therefore rising nutrients and phytoplankton. Cold eddies are zones where pelagic fish are likely to find their food. Surface currents and eddy zones offer highly complementary, useful data, completely free of charge and on a flexible basis via the MaxSea Chopper interface (choice of zone, size of the zone, etc.).

Chlorophyll Concentration

MaxSea TimeZero Plot - Chlorophyll Concentration

Chlorophyll concentration is a measure of the abundance of algae, also called phytoplankton, which account for most of the plant production in the ocean. Phytoplankton is difficult to measure directly, yet they are the direct or indirect source of food for most marine animals. MaxSea Chopper interface allows you to consult Data of Chlorophyll Concentration indicated in mg/m3.

With MaxSea TimeZero Plot, enjoy the benefit of free and accurate oceanographic data in order to identify your potential fishing zones, save fuel, time and operating costs, and achieve higher performance.
