Abstract
Sustainability of any aquaculture venture especially for enhanced food security and
socio-economic development of the target population is the challenge of the new
millennium. With the right environment and best management practices (BMPs), the
envisaged expectations of the integrated investment can be achieved. This paper
compares the economic performance and environmental friendliness of two adaptive
integrated aquaculture systems at Njala University fish farm, Sierra Leone. The studies
were carried out for six months (June-November, 2014). Fish, rice cum piggery and
fish, rice cum poultry production integration platforms were set up to perfect the ideas
of integrated fish farming in Sierra Leone. Water quality parameters measured biweekly
included: dissolved oxygen, water temperature, pH, water hardness, water
alkalinity, ammonia, nitrate, BOD and nitrite. These parameters were determined using
Jenway analytical probes and Pondlab multi-parameter kits. Three samples were
collected in thoroughly washed 600ml water bottles at each sampling point. Water
quality parameters determined in the studies were found to be within the recommended
range for the culture of tropical fish species and were not also statistically significant
(p<0.05). However, the pH of adaptive research platform (ARP) was slightly acidic.
Economic analysis gave a negative incremental benefit and Net Present Value (NPV)
for the fish, rice cum piggery synergy in the first year. The calculated benefit/cost ratio
for the pig, rice cum piggery production was positive but below 1 (0.87).The system
had a negative NPV (-Le 2,990,708), and a payback period of 1.33 years; a net profit of
Le 8,944,000 with a gross profit margin of 0.46. The fish, rice cum poultry production,
however, gave a positive NPV (Le 841,930.32 (US189.3)) and a cost – benefit ratio of
1.02. Net profit, Gross Profit Margin and the payback period calculated for the
investment were Le 13,892,000, 0.34 and 0.98 years, respectively. The poultry project
broke even and payback in the first year while the piggery project did not but can only
break even and pay back in the second year of production. The culture of genetically
poor fish fingerlings, high construction costs of the adaptive research platform, scale of
operation and pricing of the farm produce were seen as major causes of reduced
profitability. The results obtained from the study, clearly indicate that the two
integrated synergies have the potential to help solve the problems of hunger and
poverty in Sierra Leone, especially among the rural poor that constituted more than
70% of the population.
