Practice objective / multiple choice question 1 from the 2018 Gce Model Questions Vol1 Agricultural Science examination.
A tilapia farmer plans to stock a 2‑ha earthen pond. The survival rate (%) and average market weight (kg) per fish are related to the stocking density \(D\) (kg ha\(^{-1}\)) by \(S = 95 - 0.005D\) and \(W = 0.5 + 0.0002D\). The market price is ₦250 kg\(^{-1}\) and fingerlings cost ₦30 per kg of initial stocking weight. Fixed pond preparation costs are ₦20 000. Determine the stocking density that maximises net profit per hectare and calculate that maximum profit (round to the nearest thousand naira).
