Observations on the Geometrical Properties of Accuracy Growth in Sampling with Finite Populations (FAO Fisheries Technical Paper)

A common problem in sample-based surveys that are performed under operational constraints is how to scale data collection procedures so as to guarantee an acceptable level of sampling efficiency. This problem constitutes a frequent concern of fishery administrations with limited budgets and human resources. Generally, lack of guidance on sample size requirements tends to increase the size and complexity of field operations and this, in turn, has a direct impact on the logistical aspects of data collection and data management procedures. This study attempts to provide some answers to the problem and proposes a supplementary practical tool for use in the design of sample-based fishery surveys.
