“…Vannamei was influenced by seed (Sd) at 1% level of significance and labor (Lb) at 5% level of significance. [ 41 ] and [ 42 ] reported similar findings. The R 2 was 0.56, implying that 56% of the shrimp yield is explained by explanatory variables in the model.…”

The study aimed to highlight the profitability and production function analysis of Penaeus monodon and Litopenaeus vannamei in intensified shrimp farms in Gujarat (India). Two hundred and twenty (220) shrimp farm households were used to identify (principal component and cluster analyses) 8 clusters of management practices that reflected various scales of production intensity ranging from 0–2999 kg/ha/crop to 9000kg/ha/crop and above for both the species. The Cobb-Douglas production function, which relates production output to several independent input variables, was used to determine productivity. The budgeting analysis for both the species showed that more intensively managed farms performed more than the less intensive farm. Empirical results show feed as most significant input for Penaeus monodon and Litopenaeus vannamei seed and labor that affected production. Average net returns/ha/year for Penaeus monodon was $16313.13 and for Litopenaeus vannamei $41640.99. Aquaculture exhibited decreasing returns to scale for both the species and estimates on resource use efficiency revealed that in Penaeus monodon the resources were economically utilized and in case of Litopenaeus vannamei the output was likely to increase if more of seed and less of labor would have been used. The major constraint for the shrimp farmers was diseases which can be mitigated by optimum stocking densities and proper feed management.

This paper examines production costs and returns of sutchi catfish (Pangasianodon hypophthalmus) aquaculture under three different farming systems in Bangladesh. Based on the production technology, sutchi catfish farming is classified as extensive, semi‐intensive and intensive. Results showed that sutchi catfish farming is profitable irrespective of the level of intensification and in all three instances the cost of feed dominated the variable costs of production. The average annual production costs were estimated at US$5217 ha−1 in intensive farming, while US$2694 ha−1 in semi‐intensive and US$981 ha−1 in extensive farming. Despite the higher production costs per hectare, the average annual net return was higher in intensive farming (US$3364), compared with semi‐intensive (US$2048) and extensive (US$1099) farming. The average annual production per hectare under intensive farming conditions (13 945 kg) was higher than semi‐intensive (7705 kg) and extensive (3380 kg) farming mainly due to higher levels of inputs, including seed, feed, fertilizer and labour. However, the Cobb–Douglas production function model suggests that inputs are inefficiently used in the intensive farming system. Conversely, there is enough scope to increase the production and income from the semi‐intensive and extensive farming systems by using more inputs.

“…Several studies have used a Cobb-Douglas production function analysis in aquaculture, for example catfish farming in Alabama (Nerrie et al 1990), seabass and seabream farming in Greece (Karagiannis and Katranidis 2000), rice-fish culture in India (Goswami et al 2004), and prawn and catfish farming in Bangladesh (Ahmed et al 2008(Ahmed et al , 2010a. The Cobb-Douglas production function model has also been used to assess input-output relationships in agricultural productivity, including rice and wheat (Fulginiti and Perrin 1998;Ozsabuncuoglu 1998;Bakhshoodeh and Thomson 2001;Villano and Fleming 2006).…”

Integrated rice-fish farming in Bangladesh: meeting the challenges of food security

2011

In order to meet the soaring demand for food, there is a need to increase rice and fish production in Bangladesh. In spite of the potential for rice-fish farming, rice monoculture remains the main farming system in Bangladesh. However, rice monoculture cannot provide a sustainable food supply without a cost to long-term environmental sustainability. We provide evidence that integrated rice-fish farming can play an important role in increasing food production as the integrated farming system is better than rice monoculture in terms of resource utilization, diversity, productivity, and both the quality and quantity of the food produced. The Cobb-Douglas production function model also suggests that higher yields can be achieved by increasing inputs in the integrated farming system. Integrated rice-fish farming also provides various socioeconomic and environmental benefits. Nevertheless, only a small number of farmers are involved in integrated rice-fish farming due to a lack of technical knowledge, and an aversion to the risks associated with flood and drought. We conclude that integrated rice-fish farming can help Bangladesh keep pace with the current demand for food through rice and fish production but requires greater encouragement if it is to realize its full potential.
