内容記述 | The release of artificially produced juveniles is a popular tool in fishery management, with more than 26 billion seeds of 180 marine species released annually into the wild in more than 20 countries. Despite this, there is a lack of research on, and monitoring of, the effects of such stocking efforts in most programs. We aim to improve assessments of the effectiveness of marine stock enhancement and sea-ranching programs using a novel computer program to estimate stocking effectiveness based on a two-stage sampling strategy of fishery landings. We revisit our two-stage sampling method published in 1992 and briefly summarize the estimation procedure using standard literature notations. As an example, we estimate commercial landings of released Japanese flounder (Paralichthys olivaceus), the contribution of released seeds to total commercial landings, and their recapture rate. Contour lines of predicted standard errors of landings and the optimal number of days within survey budget constraints required to sample fish landings per market are estimated. Our method can be applied to any species and case involving two-stage sampling, where all released seeds are marked or tagged, including genetically marked individuals. If the number of individuals that have been released in a sample is known, the stocking effectiveness can be determined with an R script. This program can also be used to determine the optimal sampling strategy. |
