From the top of the Weekend number 1, in October 1972, it is made clear that the aquarism it is going to be one of the issues that the magazine would address. Switched on intimately with the nature and the fishing, it was considered a hobby that allows to know, especially, the exotic fish. The youngest ones calculate that, at that time, there was neither color television, nor cable, nor Internet, so it was not easy to be close to the fish fauna.
In that first issue it was Juan Martin de Yaniz the author of the initial note on aquarism, which was part of a monthly succession dealing with different topics of this hobby. From the type of chlorine, going through the fish tank glasses and following their sizes, kinds of fish, aerators and the formation of the environment, everything is reflected in this great series of articles.
Yaniz was a remarkable aquarist who as early as in 1937 he wrote his first book: “Aquariums, plants and fish”. When Weekend came out it had at least eight editions. During this period, she also gave birth to “Ichthyological Album” and “Fish and Aquariums”. He was best known in our magazine for his fishing notes, but obviously he also knew a lot about how to view fish in captivity. The scalars of Amazonas and the zebras were the first that he presented in the pages of the monthly.
Yaniz himself will make some interesting sport fish tokens, with many rich descriptive data taken from books by seasoned ichthyologists whom he admired, such as Raúl Ringuelet and Raúl Aramburu. The first notes of fish breeding and stocking also date from this initial decade, involving two species highly desired by fishermen: trout and silverside.
It was a time of great impulse of the activity. In fact, in that decade the Association of Aquarism and Ichthyology of the Argentine Republic and the Association of Amateur Aquarists of Argentina were founded. Over time, the hobby of aquarism was limited to specialized magazines. In Weekend, the activities that take place outdoors were gaining space, without neglecting the situation of the rivers and their fish wealth, and thus began a slow divorce: here we rescue these sketches of the marriage period.
