It is this way since the equator is warmer than the subtropical regions. I think warmth burns the salt from the water.
Tropical
Mostly in the tropical & subtropical regions of the earth
Density of seawater is largely a function of two factors: depth, that is, the deeper water is more dense than water at shallower levels; and temperature - water at higher temperatures is less dense than cooler water. Salinity is also a factor, but that's a localized phenomena simply because all the worlds oceans are in fact one large ocean and maintains an average overall salinity.

The regions closer to the equator are hotter and more moist than those further from the equator. They receive more solar energy than the poles.
Salinity in the ocean is highest in regions where evaporation is high and precipitation is low. Density in seawater is determined by both temperature and salinity.
subtropical regions
Yes. in fact, they can only survive in subtropical regions.
Generally the Oceans are more saline in the tropics, that is to say the sea is less salty towards the polar regions.
Surface salinity in polar regions varies seasonally due to the formation and melting of sea ice.

The salinity of water in polar regions varies seasonally because of the melting of sea ice during warmer months.
In the era of sailing ships, regions of constant winds were much appreciated. They made trade around the world possible.
