Techno-economic analysis of Shrimp farming in Coastal districts of Tamilnadu

Abstract

The present study was taken up to carry out the techno-economic analysis of the shrimp farming practices in the coastal districts of Tamilnadu. Efforts were made to study the socio-personal characters of aquafarmers, farm details, technical details, component wise cost of shrimp farming and economics of shrimp farming. The study revealed that 45.33 % shrimp farmers belonged to middle age group, 44.67 % were educated up to higher secondary level, 78.67 % of the farmers were engaged in aquaculture alone for their livelihood and 48.67 % respondents had farming experience between 5-10 years. Majority of the respondents (82 %) belonged to the marginal (54.67 %) and small (27.33 %) category of farmers. The results indicate that feed (42.94 %), electricity (10.10 %), medicines (8.97 %) and seed (8.26%) were the major costs in shrimp farming activity. Shrimp farmers earned a net profit of 11.47 lakh/ha with BCR of 1.85. On a whole Shrimp farming in coastal districts of Tamilnadu was observed to be economically viable.

“…The FAO reported substantial growth in shrimp production where, based on the estimation, the annual production of shrimp was approximately 953,310 tons in 2001, valued at nearly 5.4 million dollars, and thereafter it increased to 5.5 million tons in 2017, valued at about 32 million dollars [6]. The major market player in the global seafood market in Southeast Asia is India, but 70% of the total value comes from Shrimp aquaculture, despite having 1.2 million hectares of potential brackish water distributed in its nine marine states [7,8]. The United States, South Asia, Japan, and the European Union, along with the Middle East, China, and other nations, are the largest importers of Indian shrimp [9,10].…”

Analysis of Socioeconomics and Occupational Dimensions of Shrimp Farmers of Tamil Nadu

“…Navghan et al [16] reported a BCR of 3.06 in P. vannamei shrimp farming in Navasari district of Gujarat. And many studies have reported a BCR of more than one in India [51,52] as well as in other countries [50,53,54]. Though P. vannamei shrimp culture is profitable in India [13,16], there are certain factors that need to be addressed for the sustainability of the industry.…”
