Water visibilty of 18"-24" is productive for growing fish and reducing the amount of nuisance plant growth such as filamentous algae and submerged plants. However if you regularly feed the fish pellets the greenish productive water is not as necessary. Feeding pellets to a fish productive system does add nutrients from fish manure to stimulate some growth by planktonic algae and zooplankton. The amount grown depends on how green the water becomes toward 12"-24". Many fish production ponds such as you are planning are relatively turbid due to lots of plaktonic growth from abundant fish manure.
Your photo shows brownish pond water in the background which is likely due to mostly very tiny particles of sediment from a newly built pond. Suspended silt particles in this brown water reduce light penetration and slows planktonic algae growth. Not all bad if you are pellet feeding fish to keep them growing.
