“…In the present study, the cumulative cost of feed, labour and pond construction accounted for 81.87% of the total cost of production in Malawi. For China, feed, rent and labour accounted for a combined 83.63% of the total cost of production, which was a similar trend to earlier findings [34,35] on cobia in Brazil; [4] on Tilapia in China, however Alam and Yin, Wang, Zhou, Wang, Li, et al, [36,37] found different results in their respective studies on Pangasius hypophthalmus in Bangladesh and Crucian carp in China. Feed was actually the highest contributor to total cost, and this high cost of feed in both countries, can be attributed to the recent global economic condition which has impacted on production costs of most enterprises.…”

This study was conducted to analyse the economic profitability of tilapia farming in Malawi and China, using data from 20 farmers both in Malawi and Guangxi Province, People's Republic of China. Application of enterprise budget for profitability analysis showed that profits for tilapia were significantly different (p ≤ 0.05) between the two countries with Malawi registering a bigger benefit-cost ratio of 1.61 than 1.20 for China. However, 3 farms in Malawi posted losses during the production cycle. Breakeven price was $2.00 for Malawi against $1.26 for China. Sensitivity analysis was conducted to evaluate the influence of changes in price, feed, labour and fixed cost on net profit. Holding all conditions constant, sensitive coefficient for price was relatively high for Malawian farms at 2.63 followed by feed, labour and fixed cost at-0.70,-0.36 and-0.32 respectively. Similarly for China, price showed the highest elasticity of 5.96 compared to-3.65,-0.67,-0.27 of feed, fixed cost and labour respectively. For the farms that did not make profits, application of the shutdown rule indicated that the farms were making surplus gross margins hence could continue operating (Price ≥ Average Variable Cost; and Revenue ≥ Total Variable Cost). The present study has demonstrated that differences in input intensification result in different gross revenues since yield is a function of stocking density, feed input, labour and other production inputs. Irrespective of the intensity of input use, farmers still make profits, thus tilapia production is a viable enterprise in both countries.

“…Despite the slower growth during winter, cage culture of cobia is a flourishing activity in southeastern Brazil (Rombenso et al, 2016). In this case, one has to consider that the proximity to large consumer markets with great purchasing power, and the abundance of protected marine areas that allows the use of rearing structures with comparatively lower installation and operating costs than offshore farms (Bezerra et al, 2016), turns cobia culture into an attractive pursuit, even in areas with milder temperatures, where growth is not so fast. This highlights the need to consider factors, other than water temperature, when assessing the adequacy of a certain area for cage aquaculture.…”

“…Although marine fish culture is in its infancy in Brazil, it is estimated to have one of the largest offshore areas available for cage aquaculture in the world (Kapetsky et al, 2013). In recent years, two offshore farms operated off northeastern Brazil (Hamilton et al, 2013), while smaller scale, near-shore cobia farms operate in the states of Rio de Janeiro and São Paulo (Bezerra et al, 2016;Rombenso et al, 2016).…”

This study identified regions of the Brazilian coast that present more adequate temperature conditions for the cage culture of cobia (Rachycentron canadum). A survey of sea surface temperatures (SST) along the coast (up to the 200 m isobath) used data from the Aqua/NASA satellite. Water temperature classes that affect the development of cobia and may lead to changes in physiological activities, especially related to feed intake, growth, and mortality, were established, according to the literature. Cobia is able to grow at temperatures between 19 and 32 ºC, but the range considered optimum for growth was 27-29 ºC. The coastal area stretching from eastern Pará to the north of Bahia was considered to have the most suitable temperature conditions for commercial aquaculture of cobia. The coastline encompassing the state of Amapá to the west of Pará, and the whole coast of the southeast region presented SSTs above or below the range considered optimum for the growth of cobia, respectively. In the southern coast of Brazil, the commercial farming of cobia may not be feasible due to the low SST during most of the year.

“…O beijupirá é praticamente a única espécie de peixe marinho cultivado comercialmente no Brasil, até o momento. Sendo que a quase totalidade destes empreendimentos de cultivo estão localizados no litoral norte paulista, principalmente nos quatro municípios: São Sebastião, Ilha Bela, Caraguatatuba e Ubatuba (Sanches & Kuhnen, 2016) e no estado do Rio de Janeiro (Bezerra et al, 2016). Com estimativa de produção de até 11 toneladas no ciclo 2015/2016 (Estrada et al, 2017).…”

RESUMOApesar do potencial de cultivo do beijupirá (Rachycentron canadum), quando se fala em processamento desta espécie de peixe marinho, os conhecimentos de vários aspectos da cadeia produtiva ainda são escassos. O objetivo do presente estudo foi de avaliar o rendimento dos filés e dos resíduos da filetagem do beijupirá selvagem e cultivado, considerando-se o rendimento das vísceras (RVI), rendimento da cabeça (RCA), rendimento da carcaça sem a cabeça (RCR), rendimento do filé inteiro sem pele (RFI), rendimento da pele com escamas (PPE) e o rendimento da barriga (PBA). Foram utilizados doze exemplares de Beijupirá (Rachycentron canadum) com peso médio 2.435 g sendo seis selvagens adquiridos no comércio local do município de Itarema, estado do Ceará, e os outros seis cultivados obtidos da Fazenda de Maricultura de Búzios, localizada em Ilhabela, estado de São Paulo. Os peixes foram eviscerados, decapitados e filetados manualmente. Os resultados obtidos possibilitaram concluir que não houveram diferenças significativas para o rendimento do filé, vísceras, cabeça e pele entre os beijupirás selvagens e de cultivo. Porém, foram observadas diferenças significativas para os rendimentos da carcaça e do corte da barriga. Palavras-chave:Rachycentron canadum, rendimento, processamento.
