Evaluation of geostatistical estimators and their applicability to characterise the spatial patterns of recreational fishing catch rates

Abstract: Western Australians are heavily engaged in recreational fishing activities with a participation rate of approximately 30%. An accurate estimation of the spatial distribution of recreational catch per unit effort (catch rates) is an integral component for monitoring fish population changes and to develop strategies for ecosystem-based marine management. Geostatistical techniques such as kriging can provide useful tools for characterising the spatial distributions of recreational catch rates. However, most recre… Show more

“…During its formation, it has undergone many natural and human factors [1][2].Therefore, the nature of rock and soil is very complicated. Natural rock and soil body is not uniform and anisotropic, which determines the various properties of rock and soil with spatial variability.…”

“…The ability to take a proactive approach towards fisheries management requires data collection and stock assessment including catch per unit effort (catch rate), which is frequently used as a relative measure of species abundance. Mapping the distribution of catch rates can assist in delineating high priority areas and improve our understanding of the spatial patterns of recreational fishing at appropriate spatial scales for fisheries management (Aidoo et al, 2015).…”

“…Geostatistical estimation techniques (such as kriging) have been widely applied to characterise the spatial distribution of natural resources, including observed catch rates from recreational fishing (Aidoo et al, 2015). The nonparametric kriging approach, known as indicator kriging, is particularly helpful for estimating catch rate because it can also handle other features of the data distribution such as zero-inflation, high skewness and class-specific spatial patterns.…”
