“…Variable costs accounted for about 88% of total costs across the three farm scales. This is in line with Karim et al (2014) and Nisar et al (2021), who found similar feed cost structures in intensive shrimp production: 91% and 90%, respectively. A significantly higher (p < 0.05) feed cost was found in large farms (USD 11,152 ± 1,200 ha −1 ) than small farms (USD 7036 ± 681 ha −1 ), with feed costs in medium farms (USD 9208 ± 826 ha −1 ) at an intermediate level.…”

“…Electricity and fuels are important inputs in the intensive shrimp production for aeration of ponds. Nisar et al (2021) observed similar findings in intensive shrimp production in India. Lastly, farmers in all three scales reported similar seed, labour, harvesting and marketing and miscellaneous costs (Table 5).…”

Intensive shrimp (Penaeus monodon) production system is relatively new in Bangladesh, and has not yet been adequately described or its viability assessed. The aims of this study were to characterize, assess the economic performance and identify challenges for intensive shrimp farming in Bangladesh. A survey was conducted using a structured questionnaire enumerated between October 2016 to June 2017 with 53 farmers in three districts of Khulna Province, southwest Bangladesh. The surveyed farms were categorized into small, medium and large scale based on the number of culture ponds. The average production, operational costs, gross and net income, net income, and cost-benefit ratios were higher in large farms, followed by medium and small farms.A Cobb-Douglas production function model was used to identify factors influencing shrimp yields, with feed management, health management, pond depth and aeration identified as significant factors. The benefit-cost ratio was higher than 1, indicative of a positive investment efficiency of intensive shrimp farming system for farmers. Major challenges were associated with quality of inputs, high investment, maintenance of biosecurity and disease outbreaks, water quality, limited number of input suppliers and lack of diagnostic services and technical information at farm level. Our findings suggest that there is an urgent need for human capacity development for shrimp farm owners, workers and technicians. It is also important to improve access to quality inputs, rapid and affordable diagnostics and other technical services.

“…As a result, the efficiency of land, water, and energy use in feed-based culture is considerably greater for L. vannamei than for P. monodon (Boyd et al, 2017;Boyd, McNevin, Davis, Godumala, & Mohen, 2018). In feed-based culture, production of L. vannamei also was more than twice as profitable as was production of P. monodon in India (Nisar, Zhang, Navghan, Zhu, & Mu, 2021).…”

Globally, shrimp farms occupied an estimated 3.490 million hectares (Mha) of land and operated 2.426 Mha of production ponds in 2018. Extensive shrimp farms used 1.804 Mha of farm area (1.377 Mha of production ponds), but produced 11.4% of global shrimp production. An estimated 1.718 Mha of land was required to produce ingredients for feeds used in semi-intensive and intensive shrimp farming, bringing total land use to 5.160 Mha. Extensive production is located in the intertidal zone and much of this land formerly was or still is in mangrove areas. Expansion of shrimp farms into mangrove areas has slowed. Mangrove areas are inferior sites for shrimp farms, and governments have imposed stricter regulations to protect mangroves. Shrimp farming in mangrove areas is unnecessary to supply the global shrimp demand. Scenarios for increasing global shrimp production without further increase in shrimp farm area are presented. But, if the demand for shrimp continues to increase, it will be impossible to freeze the total land footprint for farmed shrimp, because the land needed for feed presently is roughly equal to the direct land use for shrimp farms. Direct land use for farms can be frozen through greater production pond yields.

Engineering design studies and financial feasibility assessments were made for construction, maintenance, equipment, operations, loan requirement, shrimp sales and predicted cash flows for simulated transformations of extensive shrimp farms to intensive shrimp farms in the Mekong Delta, Vietnam. Farms with less than 2.8 ha of feedbased, aerated production ponds would not be profitable at shrimp yields less than 5 t/ha/year. Profit projections increased in response to greater production area on farms and larger annual pond yields. Farms with 6 ha or more of production ponds and yields of 10 t/ha/year or more had the best profit potential. Greater profitability at higher production intensity resulted from a reduction in the labour cost/product weight ratio as yield per unit area increased. Transformation from extensive to intensive farms would allow greater shrimp production, increase worker income and lessen land and water use. Environmental benefits would include a reduction in sediment starvation of the Mekong Delta, and the option to restore some of the several hundred thousand hectares of mangrove area severely degraded by extensive shrimp farming.These two improvements would be of benefit in retarding erosion along the Mekong Delta coastline. The possibility of intensification and consolidation of the shrimp farming area in the Mekong Delta deserves further consideration.
