Economic evaluation of mud crab farming under different production systems in India

Abstract

Apart from penaeid shrimp culture, crab farming and fattening and other several diversified aquaculture practices are now emerging as viable ventures in India. About 11 types of crab products are being exported from India with an average unit value realization of US$ 3.73 kg -1 , pinpointing its importance in the foreign exchange earnings. An economic evaluation of mud crab culture, fattening and fattening with composite culture of shrimp/finfish has been attempted in this paper. The major operating cost was that of seed and it was higher for crab fattening (87% of the total operating cost). Feed costs were very low compared to that of shrimp farming. Annual profit obtained was US$ 22812.5 ha -1 year -1 for culture and US$ 30820.8 ha -1 year -1 for fattening. Economic indicators such as net profit, rate of return, pay back period and breakeven price indicate that crab fattening/culture is much more profitable than any other coastal aquaculture operations currently in practice, provided hatchery production is established in the country to ensure adequate supply of mud crab seeds.

The application of the sustainable livelihood approach to small scale-fisheries: The case of mud crab Scylla serrata in South west India

“…Socio-economic studies in Bangladesh and India under different farming systems (e.g. Ferdoushi and Guo, 2010; Jahan and Islam, 2016; Sen and Homechaudhuri, 2017) have shown that small-scale aquaculture systems have proven to be a lucrative activity which also have the potential to contribute to the wider economic context (Sathiadhas and Najmudeen, 2004).…”

Integrated rearing system approach in the farming of mud crab, shrimp, fish, oyster and periphyton in bracksihwater pond

“…Global aquaculture production (including aquatic plants) with 110.2 million tonnes and first‐sale value estimated at USD 243.5 billion in 2016 is one of the fastest growing food production sectors representing 44.2% of world fish production (FAO, 2018). Amidst the overwhelming production of shrimp among the brackishwater species, mud crab Scylla serrata is widely regarded as one of the most promising alternatives to penaeid shrimp culture (Khan & Weelden, 2017; Sathiadhas & Najmudeen, 2004). It is a high valued and fast growing species, and its culture is progressing rapidly because of its promising profitability.…”

A Comparison of the Economic Performance of Offshore and Inshore Aquaculture Production Systems in Korea

“…Standard financial performance of aquaculture fisheries production was used (Adams et al, 2001;Brown et al, 2002;Goode et al, 2002;Fong et al, 2005;Liu & Sumaila, 2007;Sathiadhas & Najmudeen, 2004). Data was collected for both inshore and offshore production, income and cost were calculated annually, and then the net present value (NPV) was calculated for a ten year production period.…”
