Chilean legislation for the control of diseases of aquatic species.

The Political Constitution of Chile establishes the right of the people to live in an environment which is free from contamination. The State has a duty to uphold this right and to preserve nature. With the aim of reconciling this constitutional guarantee with the pursuit of profitable economic activities, the concept of 'sustainable development' has been promoted. This mechanism makes it possible to use natural resources and the environment in a rational, effective and efficient manner both at present and in the future, and led to the promulgation of the General Law of Fisheries and Aquaculture No. 18,892 of 6 September 1991 and its amendments. This law regulates national fisheries and aquaculture activities throughout the country, and contains eleven regulations applicable to aquaculture. These regulations form a complete procedure of action relevant to the importation of aquatic species, to applicants for aquaculture concessions and authorisations, to the operation of these concessions and authorisations, and to ocean ranching systems. Due to the complexity of these regulations, important rules are still under study, while the remaining texts come into force on 1 September 1996. Formulating these rules involves consideration of current national and international regulations, the experience of farmers, the results of technical and scientific research, and bibliographical data. These regulations will form the cornerstone of Children aquaculture policy in confronting the challenges of the next century.
