“…The intensive farming is more lucrative than that of semi‐intensive and traditional by adoption of advanced practices (Ahmed, 2007). Alike agriculture, the fertilizer, pesticides and energy consumption also influence the total harvest biomass of the shrimp in farm (Sivaraman et al., 2015). The decision regarding farms profoundly relies on socio‐economic physiognomies of the farmers including the age, education, experiences and knowledge gaining, which directly affect the technical efficiency of the shrimp farms (Van Thap et al., 2016; Tung, 2010).…”

“…The results suggest high degrees of technical inefficiency exist among shrimp farmers. Sivaraman et al [43], on the other hand, analyzed the technical efficiency of shrimp farmers in the East Godavari district of Andhra Pradesh using SFA and found that they were 93.06% technically efficient in producing shrimp. Age, education and experience of the farmers, as well as their membership in farmers' associations and societies, significantly affected technical efficiency.…”

Uncertainty about efficiency and sustainability of shrimp production due to diseases and climatic events may prevent Vietnam from attaining US $10 million target from shrimp exports by 2025. We surveyed 120 and 159 shrimp farmers from Khánh Hòa and Trà Vinh provinces, respectively, to obtain information on their input use, production levels and the effects of diseases and climate change events on their farm profitability. Stochastic production frontier analysis (SFA) discovered that the number of workers, crops and seed costs positively influenced farmers’ profits, while cost of chemicals and labour negatively affected the profit of Khánh Hòa farmers. The number of workers and chemical costs positively affected profits in Trà Vinh, while cost of labour and energy, the number of crops and average stocking density negatively influenced farmer profit in Trà Vinh. Number of years of schooling, experience and average size of ponds positively influenced economic efficiency, while the number of ponds and climatic change events negatively influenced efficiency in Khánh Hòa province. Age and alternative power source positively affected economic efficiency, while disease prevalence affected efficiency of Trà Vinh. All farms practicing intensive or extensive shrimp production achieved 90% efficiency. The government should encourage the wise use of resources, high-quality seeds and a sensitive balance between intensive and extensive culture to sustainably attain its national production and export goals.

“…Segundo os autores, há um grande número de pequenos e médios produtores, que se caracterizam pela utilização de sistemas extensivos e semi-intensivo de produção, diferente do quadro encontrado no Ceará, caracterizado por produtores que utilizam sistemas semi-intensivo e intensivo de produção. Essas características regionais não 1 No mundo, a eficiência técnica da carcinicultura foi investigada na Malásia (Islam et al, 2014), Vietnã (Kiet & Fisher, 2014), Bangladesh (Begum et al, 2013), e Índia (Sivaraman et al, 2015). devem ser negligenciadas e, para contornar esta limitação, nesse estudo, utiliza-se a função de metafronteira de produção, a qual permite comparar o grau de eficiência técnica entre regiões, tendo como base a mesma linha de referência (benchmark).…”

Resumo No Nordeste do Brasil, a carcinicultura tem alcançado nível elevado de eficiência técnica, porém, estes avanços não vêm acontecendo de forma homogênea entre os estados produtores. Este estudo tem como objetivo analisar as diferenças tecnológicas da produção de camarão cultivado existentes entre os dois maiores produtores nacionais deste produto, Ceará e Rio Grande do Norte, em 2011. Para isto, aplicou-se o modelo de metafronteira tecnológica proposto por Battese, Rao e O’Donnell, que objetiva estimar uma função envoltória das fronteiras estocásticas de produção dos dois estados. Os dados relativos à produção e ao gerenciamento das fazendas de camarão foram extraídos do Censo da Carcinicultura de 2011, realizado pela Associação Brasileira de Criadores de Camarão (ABCC), sendo 100 fazendas localizadas no Ceará e 112, no Rio Grande do Norte. Os resultados mostraram que, em termos médios, o Ceará apresentou maior eficiência técnica (ET) do que o Rio Grande do Norte, sendo que a área média dos viveiros teve maior impacto sobre a ET do Ceará, e o número de funcionários contratados, sobre a ET do Rio Grande do Norte.
