The goal of this project was to assess the feasibility of establishing and maintaining cultures of Acartia tonsa, as well as to refine current culturing and egg separation methods. The turbidity front as a habitat for Acartia tonsa (Copepoda) in the Río de la Plata, Argentina-Uruguay Atlantic, North Sea, Barents Sea) Estuaries and brackish areas: Where freshwater meets the sea, and where salinity varies between 35 ppm and <5 ppm (such as the Baltic Sea) A. tonsa may be a recently introduced species in the Black Sea. Acartia tonsa is a widespread and numerically dominant estuarine copepod containing deep mitochondrial lineages within and among populations along the northwestern Atlantic coast. Several studies have shown that Acartia NIS are colonizing coastal areas and estuaries by propagation or introduction (e.g., [3,4]). Worldwide, in the Atlantic, Indian, and Pacific oceans, and the Azov, Baltic, Black, Caspian, and Mediterranean seas.

A. tonsa feeds on Rotifers and Ciliates, diatoms (Gonzalez, 2013). If Bradford's statement is correct, A.tonsa can fall into rostrate and/or arostrate group(s), and may be the exceptional case in the genus Acartia. Ecotoxicol Environ Saf. (2020). CONACYT/ CIQRO.
