“…Also, total feed requirement is less compared to the grow-out phase because the production cycle is shorter. Jomori et al (2005) reported that feed expenditures are directly related with the cultivation time; increasing the longer the fish remain in the production system. This study showed that in tambaqui farming, the purchase of fingerlings is the most costly item of the production cost composition, especially because development during this phase is faster and feeding requirements are lower when compared to the grow-out phase.…”

“…During tambaqui grow-out phase in ponds, labor accounts for 5.07% of TOC and 4.2% of TPC by Merola & Paganfont (1988), respectively. On the other hand, Jomori et al (2005) reported that labor participation in TOC ranged from 32.7% to 56.0% for pacu larvae, depending on the management adopted and food supplied. The intensive production systems have been continuously attracting more investors; however, one must consider that the risks also increase, while it becomes necessary to hire specialized labor, to understand the technology and keep close control of water quality (Arbelaez-Rojas et al, 2002).…”

ABSTRACT. The seeding rate is a factor that affects water quality, biological, physiological parameters, incidence of parasites and economic indicators. 72,000 fish of ± 1.9 ± 0.1 cm and 0.4 ± 0.01 g were planted in 12 ponds of 600 m² in densities of 5, 10 and 15 fish m -2 . The fish were fed twice a day until apparent satiation, with a commercial feed with 36% crude protein, for 56 days. The cost was determined based on the total production cost and total operational cost, showing unit values per hectare of water surface. Performance indicators were compared with ANOVA test with polynomial regression. The final number of fish showed a positive linear behavior, while the other performance parameters were not affected by density, thus suggesting that the pond's maximum stocking density was not reached. On investment and production costs the most representative items were nursery building and fry acquisition, respectively, which denotes that increasing seeding density positively affected the production process, improving all the economic indicators.

Efecto de la densidad de siembra sobre el rendimiento económico de juveniles deColossoma macropomum (Cuvier, 1816) en estanques RESUMEN. La densidad de siembra es un factor que afecta la calidad del agua, indicadores biológicos, parámetros fisiológicos, incidencia de parásitos e indicadores económicos. 72,000 peces de 1,9 ± 0,01 cm y 0,4 ± 0,01 g, fueron sembrados en 12 estanques de 600 m² en densidades de siembra de 5, 10 y 15 peces m -2 . Los peces fueron alimentados dos veces al día hasta su aparente saciedad, con alimento comercial con 36% proteína bruta por 56 días. El costo fue determinado con base al costo total y costo operacional de producción, mostrando los valores en unidad por hectárea de superficie de agua. Los indicadores de rendimiento fueron comparados con la prueba de ANOVA con regresión polinómica. El número final de peces mostró un comportamiento lineal positivo, mientras que los otros parámetros de rendimiento no fueron afectados por la densidad de siembra, sugiriendo que la máxima densidad de siembra de los estanques no se alcanzó. En la inversión y en los costos de producción los elementos más representativos fueron la construcción de viveros y la adquisición de alevines, respectivamente. De esta manera, se determinó que el aumento de la densidad de siembra afectó positivamente el proceso de producción, mejorando todos los indicadores económicos. Palabras clave: Colossoma macropomum, cachama negra, piscicultura, rendimiento, evaluación económica, costo de producción, Brasil.

“…Gomes et al (2000) also pointed out that stocking biomass has to be considered from an economic point of view, since it influences fish farming costs. Jomori et al (2005) suggest that the use of the facilities can be optimized mainly by increasing SB, since more densely populated ponds would further increase the productivity of the system and consequently, dilute fixed production costs. This optimization can be seen especially in ponds 3, 4, 5, 6 and 8, where increased productivity diluted costs.…”

“…However, literature about tilapia cultivated mostly in net cages (Ayrosa et al, 2011;Firetti & Sales, 2007;Furlaneto et al, 2006;Scorvo Filho et al, 2006;Vera-Calderon & Ferreira, 2004), and some native species, especially pacu Piaractus mesopotamicus in fishponds (Barros et al, 2010;Furlaneto & Esperancini, 2009;Izel & Melo, 2004;Jomori et al, 2005;Melo & Pereira, 1994) can be found. No literature was found on the native species cultivated in Mato Grosso, where the geographic, climatic and rearing areas consisting of large farming systems markedly differ from other Brazilian states where, in most cases, fish are reared in smaller ponds.…”

-Performance and economic indicators of a large scale fish farm that produces round fish, located in Mato Grosso State, Brazil, were evaluated. The 130.8 ha-water surface area was distributed in 30 ponds. Average total production costs and the following economic indicators were calculated: gross income (GI), gross margin (GM), gross margin index (GMI), profitability index (PI) and profit (P) for the farm as a whole and for ten ponds individually. Production performance indicators were also obtained, such as: production cycle (PC), apparent feed conversion (FC), average biomass storage (ABS), survival index (SI) and final average weight (FAW). The average costs to produce an average 2.971 kg.ha -1 per year were: R$ 2.43, R$ 0.72 and R$ 3.15 as average variable, fixed and total costs, respectively. Gross margin and profit per year per hectare of water surface were R$ 2,316.91 and R$ 180.98, respectively. The individual evaluation of the ponds showed that the best pond performance was obtained for PI 38%, FC 1.7, ABS 0.980 kg.m -2 , TS 56%, FAW 1.873 kg with PC of 12.3 months. The worst PI was obtained for the pond that displayed losses of 138%, FC 2.6, ABS 0.110 kg.m -2 , SI 16% and FAW 1.811 kg. However, large scale production of round-fish in farms is economically feasible. The studied farm displays favorable conditions to improve performance and economic indicators, but it is necessary to reproduce the breeding techniques and performance indicators achieved in few ponds to the entire farm.

“…Guerrero-Alvarado (2003) relata que, durante o condicionamento alimentar de pintado (Pseudoplatystoma corruscans), os custos de produção mais representativos foram mão de obra, energia elétrica e alimentação. Na larvicultura de pacu (Piaractus mesopotamicus), os custos com alimentação e mão de obra representaram aproximadamente 71% dos custos de produção, em sistema de larvicultura mais intensiva, com criação das larvas por nove dias, em condições controladas em laboratório (Jomori et al, 2005).…”

Resumo -O objetivo deste trabalho foi avaliar a frequência alimentar e a taxa de arraçoamento durante o condicionamento alimentar de juvenis de pacamã. A alimentação de três e quatro vezes ao dia e as taxas de arraçoamento de 50, 75 e 100% da biomassa foram testadas. O manejo alimentar não afetou o crescimento, a sobrevivência, a mortalidade e o canibalismo dos peixes. A ausência de efeito do manejo se manteve quando os animais foram alimentados com ração extrusada, três vezes ao dia, durante 30 dias. A taxa de arraçoamento de 50% da biomassa e a alimentação por três vezes ao dia podem ser utilizadas no condicionamento alimentar de juvenis de pacamã.Termos para indexação: Lophiosilurus alexandri, canibalismo, frequência alimentar, taxa de arraçoamento. Feeding frequency and rate during feed training of Pacamã juvenilesAbstract -The objective of this work was to evaluate feeding frequency and rate during feed training of pacamã juveniles. Feeding for three or four times a day and the feeding rates at 50, 75 and 100% of biomass were tested. Feeding management did not affect fish growth, survival, mortality, and cannibalism. Lack of management effect was kept when animals were fed extruded feed threefold a day, during 30 days. Feeding rate at 50% of biomass and threefold-a-day feeding can be used for the feed training of pacamã juveniles.
