In Portugal, the spatial distribution and abundance of the black scabbardfish (BSF) is mostly unknown, the existing information relying on data from commercial fisheries. Available data refers to areas where fisherman expect to have higher catches of the species, resulting in fishing locations that are not selected randomly but preferentially. The BSF captures in Portuguese waters were previously modelled, taking the sampling preferentiality into account, using a Bayesian approach and INLA methodology, considering stochastic partial differential equations (SPDE) for geostatistical data, jointly with a Log-Cox point process model. Based on this work, the aim of this study is to construct a new survey design to improve the BSF capture estimates and to analyse the effect of preferential sampling on the choice of new sampling locations and its influence in the sampling design choice. Within this approach, different design classes are investigated, namely random, simple inhibitory and adaptive geostatistical sampling designs, regarding the problem of spatial prediction, in order to achieve the optimal BSF design towards the objective of the analysis.
