*5.2.1 Salinity and phytoplanktonic blooming*

In the spring of 2018, there were records of phytoplanktic blooming of the cyanobacteria *Synechocystis* spp., in the period December 10–17. Domingos et al. [1] argue that a rise in salinity is a limiting factor for the presence of cyanobacteria of the *Synechocystis* genus. This means that the reduction of the values of the parameter may have provided conditions that were favorable to their growth in the Lagoon.

When compared with the springs of 2014, 2015, and 2016, the parameter was between 4 and 6 units below the others in 2018 as induced in **Table 7**.
