Nowadays, aquaculture is developing strongly due to its enormous economic benefits. One of the most crucial tasks in aquaculture is to find out a solution in terms of supplying seawater proactively, safely, and appropriately to natural conditions as well as the production scale of the region. To tackle this problem, we need to undertake far-reaching research to analyze the characteristic factors of the natural conditions including topography, geology, hydrogeology, coastal morphology, sediment transport, tidal regime, waves, wind, storm, the water supply scale, etc. These elements have impacts on the selection of saltwater supply solutions. This article will address these mentioned issues.
