Rosenthal research focused on two areas:

1. Aquaculture: Here, he concentrated on applied research on the one hand, particularly on closed-circuit fish farms, and ecological aspects on the other, in particular control and prevention of pollution, and sustainability especially in developing countries.
2. Ballast water: Rosenthal was one of the first to recognize and research the danger posed to ecosystems by the transport of marine life across huge distances in the ballast water of ships. He lobbied for regulations and other measures to combat this danger.

In addition to his own research, Rosenthal played an important role in the international collaboration of hydrobiologists and aquaculturists, in particular between Canada and Germany as well as Israel and Germany.
