1. A method for measuring aquatic biomass, the method comprising:
flowing aqueous liquid and aquatic biomass in a pond;
measuring light absorption of a portion of the aquatic biomass, wherein the measuring comprises use of a measurement device, wherein the measurement device comprises:
a shield, wherein the shield obstructs flow of the biomass in an area adjacent to a shield; and
light intensity sensors, wherein the light intensity sensors comprise at least three light intensity sensors, wherein the light intensity sensors collect measurements of light intensity:
at a comparator region located above a surface of the aqueous liquid;
at a flow obstruction region located below a surface of the aqueous liquid in an area substantially free of an aquatic biomass; and
at a biomass region located below a surface of the aqueous liquid; and
determining a value for mass, surface area, density, or combinations thereof of the aquatic biomass in the pond.
