Many island and coastal communities still rely on traditional fishing tools like spears, rods, traps, and hand-thrown nets.

Aquaponics refers to a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient rich aquaculture water is fed to hydroponic grown plant, involving nitrifying bacteria for converting ammonia into nitrates.

The production of quality fish food for a wide range of species requires a number of factors to be taken into consideration, such as: density, water stability, nutritional composition (recovery of essential amino acids and vitamins) and digestibility.
