Correction to: S. Goddek et al. (eds.), Aquaponics Food Production Systems, https://doi.org/10.1007/978-3-030-15943-6

This book was inadvertently published with a typo in Chapter 3 Page 37; NO2 should have been printed as NO2.

Also in Chapter 7 Page 197, incorrect DOI was printed. Correct DOI is https://doi.org/10.1016/j.aquaculture.2018.03.021

Both corrections have now been incorporated and are correctly appearing in Chapter 3 page 37 and Chapter 7 page 197.
