Fish are the most important part of aquaponics without them it would just be a hydroponic system dependent on chemicals to set the ph and feed levels. I am often asked about the fish in our system and if they have to be a special type of fish.
The fish in our tank are currently just simple gold fish. we are planing to make a switch to Tilapia and raise them for food in the near future adding another source of food production to the vertical farm.

|Nile Tilapia oreochromis Niloticus|
The Nile Tilapia (Oreochromis Niloticus) has become the most popular fish used in aquaponics. it is a fast growing fish that produces a large quantity of waste. they are known as " The Chicken of the Sea" as they are high in protein and can be raised quickly at low cost being ready for harvest from 6 months or 500g in weight. and like to live at a temperature suitable to most plants.
other popular edible varieties include; Carp, Perch and Trout. as they all like to live in conditions that are suitable for plants to grow in and not being too fussy or high maintenance.
