We can say that blackbass the same one with mangrove jack because their live in same environment its mangrove and saltish water.
But sometimes blackbass is more difficult to adapt with extreme condition like changing water temperature, shine etc inspite of this, mangrove region do not guarantee there is a blackbass.
Blacktbass isnt a school fish its a sensitive fish that every fisherman so pleasant to get one.
GO FISH BY CONSERVE!!!
