Aquaculture

The sturgeon population is endangered in its existence worldwide. Numerous reasons have led to a dramatic decrease in population especially over the last two decades. Aquaculture can contribute to rebuilding wild sturgeon stocks and to meeting the demand for black caviar.

Although cobia (Rachycentron canadum) is still unknown to most consumers it is generally considered to be one of the most promising candidates for marine aquaculture. It is an excellent food fish. It grows extremely fast and is relatively robust. Its firm, white flesh has a nutty, buttery flavour and is rich in Omega 3 fatty acids. Everywhere, where cobia is already available on the market, demand is growing. Aquaculture production is rising.

Diseases are functional disruptions which can have adverse effects on the existence of all living organisms, including fish. In natural habitats such as rivers, lakes and seas, fish diseases often go unnoticed. In aquaculture systems, however, they are more easily recognized, particularly since high stock densities promote spreading of infection. Fighting these diseases is difficult because the necessary drugs are lacking or they are not authorized. This creates a state of emergency when therapy proves impossible.
