A New Book on the Farming of Freshwater Prawns
Macrobrachium: The Culture of Freshwater Prawns, a compilation of the global information on the farming of freshwater prawns of the genus Macrobrachium with special emphasis on India, has 169 pages, 41 black and white and 60 color pictures, numerous tables and diagrams and over 200 references (most of them since the year 2000). Modestly priced, it is available from Dr. C. Mohanakumaran Nair (firstname.lastname@example.org), one of the authors (below), for $25 (plus postage and packing). It begins with a brief introduction to the biology of freshwater prawns and their culture, followed by a review of the global statistics on prawn production, which show that production is nearing 500,000 metric tons annually, valued at $1.8 billion a year.
Freshwater prawn farming in India has soared from less than 500 tons in 1996 to nearly 43,000 tons in 2005–2006, when prawn exports totaled nearly 6,200 tons with a value of $56 million. Comprehensive information is provided on the business climate, technical issues and constraints to prawn farming in India, along with an examination of the scientific literature on prawn farming in India. While the book highlights prawn farming in India, it also discusses prawn farming in ten other countries (see list in the Table of Contents below).
A Couple of Brief Excerpts
From Chapter One: Although dozens of species of prawns exist around the world, only the giant freshwater prawn (M. rosenbergii) and the oriental river prawn (M. nipponense) are farmed on a commercial scale. Many other species, including the monsoon river prawn (M. malcolmsonii), have been grown on a smaller scale, while other species have been reared experimentally or in pilot-scale operations. From a consumer’s point of view, unlike marine shrimp, size is not the only criterion in determining the value of prawns; taste and familiarity are also important factors. In China, for example, the indigenous M. nipponense, though small, is thought to be tastier than M. rosenbergii.
From the Notes Section: The lay terminology for prawns and shrimp varies around the world. Sometimes the words denote size (shrimp are small, prawns are large), and sometimes their use is colloquial to the country where they are being discussed. It’s best to use the word “shrimp” for marine species and “prawn” for freshwater species, in accordance with the Food and Agriculture Organization (FAO) of the United Nations. Michael New (below), the senior author of this book, is a little concerned about the use of the word “scampi” for prawns, which is commonplace in India and in this book, because “scampo” (the plural of scampi) is the Italian word for Nephrops norvegicus, also known as Norway lobster, Dublin Bay prawn and langoustine. Scampi are markedly different from prawns in shape, appearance and taste. The fleshy tail of scampi is closer in taste and texture to lobster and crayfish than to prawns and shrimp. To further add to the confusion, in Belgium various crustaceans are referred to as “freshwater scampi” or “marine scampi”, and in Canada and the USA, “scampi” is often used to refer to large shrimp and prawns.
