Neco 2019 Agricultural Science Question 10
Practice objective / multiple choice question 10 from the 2019 Neco Agricultural Science examination.
A rectangular earthen pond has a surface area of 2 ha (20 000 m²) and an average depth of 1.5 m, giving a water volume of 30 000 m³. A farmer wants to stock tilapia. Each fish gains 2 g per day and the culture period is 180 days. Feed conversion ratio (FCR) is 1.5 kg feed per kg weight gain. Feed costs \(\text{₦}200\) per kg, and market price of fish is \(\text{₦}500\) per kg. Fingerlings cost \(\text{₦}50\) each. Mortality increases linearly with stocking density D (fish m⁻³) as 5 % × D (i.e., mortality = 0.05D, no cap). Determine the maximum initial stocking density (fish m⁻³) that will still give the farmer a profit of at least \(\text{₦}1,000,000\). Show all steps.
