CHAPTER ONE INTRODUCTION Background to the Study
A fish pond is an artificial lake (reservoir, pond) intended for fish breeding. In the medieval times in Europe, it was typical for many monasteries and castles (small, partly self sufficient communities) to have its fish pond. Fish ponds are still common in Canada, Europe, especially in the Czech Republic, where common carp may be kept and in East Asia where koi may be kept. Such ponds are also being promoted in developing countries. They not only provide a source of income for small farmers from the sale of fish but can also meet irrigation needs and water for livestock (FAO, 2009).
