______ means the number of fish in a pond or raceway.

• A. Stocking rate
• B. Standing crop
• C. Feeding rate
• D. Inventory

Answer: (A)

Stocking rate refers to how many fish are introduced into a pond or raceway, usually expressed as fish per unit area or per unit volume (for example, fingerlings per acre or per cubic meter). This value sets the initial density of the population and is a planning measure that influences growth, feed needs, water quality, and overall production outcomes. The phrase “the number of fish in a pond” aligns with stocking rate because it describes how many fish you stocked to establish that population, rather than the current population size or biomass, which would be described by standing crop. Feeding rate and inventory relate to how you manage feed or track stock across ponds, not specifically to the count of fish in a single pond.
