While significant worldwide distribution of tilapias, primarily Oreochromis mossambicus, occurred during the 1940s and 1950s, distribution of the more desirable Nile tilapia occurred during the 1960s up to the 1980s. Nile tilapia from Japan were introduced to Thailand in 1965, and from Thailand they were sent to the Philippines. Nile tilapia from Cote d’Ivoire were introduced to Brazil in 1971, and from Brazil they...

Aquaponics is a combination of aquaculture, which grows fish and other marine animals such as Australian blue crayfish, and hydroponics, which grows plants without soil. These beneficial bacteria congregate in the spaces between plant roots and convert fish waste and solids into something that plants can use to grow. What is aquaponics? The basic principle of aquaponics is that the waste produced by your fish feeds the plants...
