Abstract
Information on the economic viability of
aquaculture is crucial for investors when assessing the feasibility of an
aquaculture investment. Unfortunately, such information has been scarce In
Sudan. this article to evaluate the effects of two fish culture systems and
four different stocking density on costs of production economics of Nile
tilapia (Oreochromis niloticus) and catfish (Clarias gariepinus)
fingerlings reared in an indoor of concrete ponds and few water-exchange
conditions. Nile tilapia (O. niloticus) and catfish (C. gariepinus)
cultured monoculture and polyculture different stocking density (SD) (SD12, SD24,
SD36 and SD48 fish/m3) was; stocked into seven treatments (1T:0C, 0T:1C, 1T:1C,
2T:1C, 3T:1C, 1T:2C and 1T:3C for experiment. Fingerlings cultured for sixteen
weeks. The evaluation showed all culture practices to be economically viable
although at varying degrees. Culture of Nile tilapia (O. niloticus)
showed the highest viability and profitability of the seven evaluated culture
practices (mono and polyculture). This was attributed to its higher turnover
rate and price compared to the catfish C. gariepinus. Monoculture of
catfish C. gariepinus showed lower viability compared to the Nile
tilapia O. niloticus. However, economic analysis showed that this could
be improved by enhancing productivity per unit value of input by using better
fish breeds, feed with higher conversion ratios and efficient production
management practices. Also, the different stocking density (SD), the treatment
SD36 fish/m3 showed production indicating best values for financial ratios.
despite there were no significant differences (p>0.5) between SD36 fish/m3
and other stocking densities (SD12, SD24 and SD48 fish/m3). The success of
aquaculture in Sudan will not only depend on the use of higher yielding species
and efficient aquaculture production technologies, but also on the confidence
of investors. For this reason, the Federal Ministry of Livestock and Fisheries
(FMoLF), Sudan, needs to have appropriate information available to investors in
their process of making economic decisions on aquaculture investments.
