There has been some interest in tilapia aquaculture in Uruguay. In order to evaluate the potential of tilapia aquaculture under the overall conditions in Uruguay, a core from Genetically Improved Farmed Tilapia (GIFT) was introduced from Brazil few years ago. The plan is to create lines of tilapia that cope with the overall conditions in Uruguay especially weather whereas the long winter is very cold. The importance of that is quite obvious especially and as known that -in general- is intolerant to low water temperature. Thus, and as shown in the photos, the experimentation is carried out in this research facility whereas breeding program is conducted through testing, selection and cross breeding as indicated by numbered cages. Once the target seeds of Nile tilapia with the desired characteristics are produced, disseminating and seed for commercial establishments will commence.

The breeding of ornamental fish is considered the oldest aquaculture activity in Uruguay. This activity, despite being undervalued by big businessmen, it takes place in a national market in which they move about 500,000 fish per year, most of which are bred in Uruguay by artisanal farmers. This number is considered significant especially when knowing that the population of Uruguay is only around 3 million of inhabitants. The farm as shown in the photos includes various types of facilities including ponds, tanks and greenhouse. This given project is dedicated mainly to the extensive breeding of goldfish, (Carassius auratus auratus).

The three photos show of an establishment for the culture of Siberian sturgeon (Acipenser baerlii) that is located on “Departamento de Durazno” on the Rio Negro “Black River”. This facility is the most developed sturgeon farming activity in Uruguay. The target of this project is to obtain caviar. Different breeding phases are carried out in the facilities as shown in the photos. The phase of seed production and nursing lasts about 6 months and carried out in indoor facilities in the hatchery. Afterwards, fish are transferred and reared in floating cages for a period of about 12-18 months reaching a size that allows sexing. Sexing is done by individual laparoscopy. Only females are moved to raceways to continue their growth for another 5 years.

This photo shows a cage farm in western Greece. In fish farming of seabass and seabream in sea cages stocking density is between 20-30 kilos/m3 and leads to the production of marketable size fish (300-450 gr) in 14-17 months

This photo is taken from a typical cage farm in Greece for European seabass (Dicentrarchus labrax) and gilthead seabream (Sparus aurata). The cages are installed in depths of more than 30 m. Each cage has a perimeter of 60 meters. The net can go up to 10 meters depth. Every cage can host a biomass of 56 tonnes of fish.
