Semi-intensive Culture Techniques for Shrimp Farming

Abstract

Aquaculture, though considered to have over a 2,500 year history, was mostly practiced as an art. It began to be transformed into a modern science in the second half of the twentieth century. Within a period of 25 years or more, it had begun to impress upon as a major food production sector, having recorded an annual average growth rate of nearly 8 % in the last two decades, as often purported to be the fastest growing primary production sector. Currently, aquaculture accounts for 50 % of the global food fish consumption (De Silva and Davy 2010). The sector has been and continues to be predominant in developing countries, particularly in Asia, which accounts for more than 85 % of the global production. Asian aquaculture by and large is a small-scale farming activity, where most practices are family owned, managed, and operated. The sector has provided direct and indirect livelihood means to millions, a significant proportion of which is rural, and for some Asian nations, it is the main source of foreign exchange earnings. Furthermore, it has contributed to food security and poverty alleviation and therefore is considered to be a successful primary food sector globally (De Silva and Davy 2010). Shrimp industry is a key sector in Indian economy because of its significant contributions to export earnings and gainful employment. But in reality, shrimp exports in the country have stagnated since late 1990s. Problems began a few years earlier with the outbreak of white spot disease (WSS). Later on, the judgment by the high court of India on shrimp aquaculture also had profound impact on its advancement. In response to address the rising concerns about the sustainability of the sector, in the year 2000, MPDEA with the technical assistance of NACA initiated the aforementioned project.
