The peer-reviewed series offers books that illuminate the multifaceted history of the Cold War in both its European and Global dimensions, across and beyond the Iron Curtain. It focuses on the interactions, interdependencies and co-operation of Eastern state socialist countries (and their citizens) with Western capitalist, Latin American, African and non-aligned states (and their citizens), as well as with China.

National audience ; Diseases of intensively farmed animals are generally explained by environmental factors, some of them being frequently affected by zootechnical practices or by the development of pathogenic organisms favoured by host animal density. Such is the case of intensive fish farms, in which the density of water confers a special importance to physical and chemical parameters associated with water quality, making management procedures a key factor in combatting diseases. Control of parasites or viral and bacterial infections, however, remains a serious matter of concern. Since the early sixties, the range of documented diseases in France has not ceased to increase and to transform for different reasons: acquirement of knowledge on the pathogens, increased variety of fish species tentatively farmed, development in international trade of living fish in response to globalization. Therapy and vaccination being dependent upon the targeted organisms and the background in which they are applied, health control procedures very soon appeared as an effective method for disease prevention. Encouraged by the directives of the European Union, official heath control systems were progressively tested and adopted, resulting in a fair level of success. This success depends on necessary adaptations to local situations and on the commitment of fish farmers. Health control policies should therefore remain reactive and constant attention should be paid to disease evolution in a sector of activity very prone to quick changes.
