Catch and effort data is used as the main source of information by Saint Vincent and the Grenadines Fisheries Division to assess the performance of the fisheries sector. Data is collected thorough sampling of landings from landing sites. These sites are widely dispersed in the multi-island state. A census in space sampling and time sampling strategy is utilised. Monthly catch estimates are generated for each landing site and to produce annual catch estimates by estimating the sum for all landing sites. This study evaluates sample-based survey strategies for sampling and estimating fisheries data and utilises the findings to provide recommendations to fisheries managers in Saint Vincent and the Grenadines. The current data collection and estimation method being used by fisheries managers in Saint Vincent and the Grenadines was also evaluated. The study found Neyman (optimal) sampling strategy to be useful in producing reliable estimates utilising less samples compared to unstratified and proportional sampling. This is important to Saint Vincent and the Grenadines where the budget is limited and sample sizes tend to be low.
