Depends on which level you start.

The FAO small scale aquaponics manual http://www.fao.org/in-action/globefish/publications/details-...

The Aquaponics Farmer (some quibbles, don’t sterilise the water with UV constantly) https://www.amazon.com/Aquaponic-Farmer-Complete-Operating-C...

Commercial Aquaponics systems, Wil Leonard (the book and other resources) http://www.aquaponic.com.au/index.htm

Small scale mealworm farming https://www.mealwormfarming.org/

We started with reading two things:

- Small scale aquaponic food production. Integrated fish and plant farming, FAO, http://www.fao.org/in-action/globefish/publications/details-...

- The Aquaponic Farmer: A Complete Guide to Building and Operating a Commercial Aquaponic System, Southern and King, https://www.amazon.com/Aquaponic-Farmer-Complete-Operating-C...

Then we visited several operating facilities, including:

- Oberous Farms, https://www.ouroborosfarms.com

- Duurzame Kost, https://duurzamekost.nl

Then we have done a ton of research ourselves.
