                  Roots of Aquaponics

 INTRODUCTION

Aquaponics  is
a combination of aquaculture and hydroculture which includes elements of
recurculation  and symbiosis(1),its gives
output of vegetables and fishes utilizing water which is nutrient rich and fish
food and excreata as a basic source,again it is a soilless culture. History
says that one of the ancient practice is using fish waste as fertilizer for
crops.”stationary islands” set up in shallow lakes in central
America(e.g.,Aztec’s Chinampas 1150-1350
BC)2. In South East Asia about 1500 years ago used to introduction of
fish into paddy fields3 ,researchers at the New
Alchemy Institute North Carolina State University (USA) in 70’s and early 80’s
developed the basics of modern Aquaponics4. Good mile stone was set up in year
1980 at the  University of the Virgin
Island(UVI) 1.A survey, conducted by Love et
al. 4, shows that
aquaponics has been receiving growing interest since then 5, which  point out
its increasing  food security  for society.

Food security would be particularly
belongs to global population it now exceeds 7.2billions and is growing rapidly 9.6
billions around 2050.6Urban population growth will require an increasing
demand for animal protein7.

Aquaculture  is
closed system of  fish farming,  where commercial fishes (catfish,ornamental
fish,cray fish or prawns etc.)are grown under controled conditions  in container. 
It includes a new aproach called recirculating aquaculture system (RAS),  reuse of water with
