Abstract
In the late 19th century, there was a bloom of public aquariums throughout Europe. Some of them were built for entertainment purposes, whereas others were connected to marine science stations. This article explores the origins and development of the aquarium/marine research station Vasco da Gama (Portugal) as an example of this duality. Initially, the aquarium was created in 1898 by the Portuguese Society of Geography, in a political context of national affirmation. In the first years, a deficient establishment, lack of financial resources, and scarce technical knowledge contributed for its degradation. Therefore, the Navy took over the aquarium in the early 1900s, delivering its management some years later to the Portuguese Society of Natural Sciences. After improvements and modifications, it became one of the first marine biological stations in 1919. This was important for the development of national marine science research at a time of scarce resources. Despite many years of a symbiotic relation between science research and dissemination, the demolition of part of the aquarium/marine station due to a road construction in 1940 brought issues of disequilibrium between both functions. This eventually led to the separation of aquarium and marine station in 1950. Other themes such as connections to national and international institutions are also discussed.
