Macroalgae vs Microalgae Yields

While microalgae are the most researched species when it comes to biofuels, one should remember that macroalgae have some advantages. Mainly because of their relatively larger sizes than micro, these can be harvested more easily.
However, microalgae are more favored primarily because of the fact that they grow very quickly and also because they have much higher lipid content than macroalgae, which normally have minimal lipid contents...
Which brings me to the question: For an equivalent area (say a hectare), is there any study that says the amount of macroalgae biomass that can be generated? It does not matter if the oil content is low (as their carbohydrate content can be used). If the yields of algae biomass for macro and micro algae are similar, then I guess there is a strong case for considering macroalgae as well...on the other hand, if the macroalgae yields are far lower, guess microalgae alone have the potential...
Any inputs are welcome
