| We examined the sampling effort required to estimate annual fishery landing statistics from the artisanal fishery. Using the observed variability among landing days in two villages in Zanzibar, Tanzania, we are able to present the relationship between predicted precision and sampling effort and take advantage of the strong correlation between lunar day and landings to demonstrate a potential gain in sampling efficiency of 30 % from stratification. The observed data are then used to simulate a 'virtual' year of landings for the two villages and demonstrate how the simulated year of observations can be used to simulate and assess various sampling strategies. In addition, it provides a heuristic tool for demonstrating the likelihood of how much anyone sampled... |
