Species guide

Tilapia

Oreochromis niloticus

Fast-growing, hardy and tolerant of high stocking densities — but that density puts real pressure on water quality, so pond conditioning matters as much as the feed.

Floating and sinking feed together

Tilapia take floating pellets readily, so a floating feed alone is normally enough and lets you see appetite at every meal. Add a sinking feed only if the pond also holds carp or other bottom feeders.

Good practice

  • Stock all-male (monosex) seed for even growth and no unwanted breeding.
  • Feed at the same times every day; the fish learn the routine and come up to feed.
  • Healthy tilapia clear their feed within about 10 minutes. Food left after that means the ration is too high.
  • Hold back feed when water is below 20 °C or above 35 °C.
  • Exchange some water regularly in densely stocked ponds to keep the fish eating well.

Mistakes to avoid

  • Mixed-sex stocking, which leads to breeding in the pond and stunted fish.
  • Stocking densely without enough aeration.
  • Relying on sinking feed for a species that feeds near the surface.
  • Not managing off-flavour in the weeks before harvest.
  • Bringing in seed without checking where it came from.
