Shearwater Bay mariculture in Lüderitz cultivates seaweed Macrocystis pyrifera of three populations namely, California, Cape Town and Falklands Island. This baseline study aims to assess the initial state of benthic macroinvertebrate communities within kelp mariculture project (Shearwater Bay site) in contrast to a non-cultivated site (Grossebucht) and adjacent sandy shores. A systematic field sampling of transects will be done , using a Van Veen grab for offshore sediment collection and quadrat sampling using core for intertidal sandy shores sediment collection. This is done to examine the composition, abundance and biomass macroinvertebrates . Physiological parameters ( temperature, dissolved oxygen, pH and water depth) will be measured . To ground truth manual identification, DNA based analysis will be carried out for species identification at all sites. Sediment grain analysis will be carried out as recommend by studies that kelp cultivation could possibly influence sediment and organic matter at cultivation sites. The data collected will be tested for normality using the Shapiro Wilk Test at alpha level 0.05. The Shannon Wiener Diversity Index and the Evenness Index will be used to examine the distribution of taxa and species abundance (individuals ). Multiple regression analysis will be used for normally distributed and DIVERSE and PRIMER V6 will be used to evaluate ecological parameters. If the distribution of the data set is not normal the Kruskal Wallis (non-parametric) test will be used . The results of this research may aid future studies that aim to compare and understand the impacts of kelp cultivation on the explored population as a way to mitigate possible impacts.
