Thinking of Exporting a Plant Product to Europe?

Under EU [European Union] legislation, any food that has not been commonly eaten in Europe prior to 1997 is classified as a ‘novel food’ and must gain special approval before it can be used in products for the European market

Correspondence about Tilapia Production using Periphyton Aquaculture Technology (PAT)

Bill Mebane corresponded with ECHO’s Farm Manager Danny Blank regarding some questions about tilapia production. We excerpt some of the correspondence here, for your information.

Danny had asked for advice and feedback about ideas for a flow through, green water system using periphyton aquaculture technology (PAT), and for a stagnant green water system using PAT. He also asked about the recommended surface area and depth of a pond used for PAT.

Bill Mebane responded, “Regarding flow-through vs. static systems—the recommended turnover using PAT is no greater than once every two weeks. This number is based on available nutrients (the object is to keep enough nutrients in the pond to maintain healthy periphyton).

The main purpose of this article is to provide introductory information for those who are new to peanuts and may be wondering how peanut varieties or subspecies may differ from each other. 

A Low Resource Method to Raise Fish in Haiti

William Mebane

Information about reports of success in Haiti with a technique developed in Israel for growing “organically certified” tilapia by adding (1) submerged bamboo poles or palm fronds and (2) a submerged “compost pile” to fertilize the pond. Microscopic organisms collectively called “periphyton” grow on the surface of the submerged poles or fronds. This is the preferred food for tilapia. According to Bill Mebane, “If used properly, the method can produce high quality protein for human consumption using a minimum of precious human and natural resources.”
