Patterns of phytoplankton community structure and diversity in offshore finfish cages in the Mediterranean Sea (Monastir Bay, Tunisia, 2018)

The dataset includes measurements of key environmental parameters such as temperature, salinity, dissolved oxygen, and nutrient concentrations, together with data on phytoplankton composition and abundance. These data can be used to evaluate the influence of aquaculture activities on water quality and phytoplankton dynamics in coastal Mediterranean ecosystems.
