Having alternative sources to marine omega-3 is not only important to ensure production, it is also indispensable for the health and well-being of fish.
The scientific article entitled "PTEC-INVA Technology Program and the Biggest Challenges of Chilean salmon farming"which was written by the manager of PTEC-INVA, Dr Daniel Nieto Díaz-Muñozand by the person responsible for communication and dissemination of the same Programme, Adam Mumtaz Troncoso, for Journal Different Versionaddresses technological development and current challenges in the salmon industry. The text highlights the evolution from rudimentary methods to advanced technologies, along with a greater focus on the sustainability and the relationship with communities local.
Two key technology programmes supported by the Production Development Corporation are mentioned (Corfo): the Technological Programme for the Development of Oceanic Aquaculture (PTECAO) and the Technological Programme for the Local Production of Nutritional Insumes for Aquaculture (PTEC-INVA). Special emphasis is placed on the latter because of its strategic importance by linking two of the country's main productive sectors: aquaculture with agriculture.
Holistic approach
One of the main challenges in the salmon industry is reduce antibiotic useThis has led to an approach to genetic improvement, fish health management and adequate nutrition. Mentioned change in the food paradigm, moving away from flour and fish oil to vegetable sources of protein and oils.
The article also highlights a study on the use of canola oil with high omega-3 content as an alternative to fish oil in food salmon and trout. And it is concluded that genetically modified canola oil (GMO) is an option efficient and safe. In addition, legal challenges related to GMO foods in Chile are discussed.
The text also addresses the need to promote local production of plant inputs for aquaculture, which could generate economic opportunities in the agricultural sector. It presents information on the dependence of the Chilean salmon industry on flour and fish oil, and stresses the importance of reducing this dependency by the cultivation of plant inputs.
Finally, the importance of food in aquaculture is underlined, given its relevance to total production costs, and an analysis is presented on the planted area in Chile for relevant crops in fish feeding.
In summary, the article highlights the technological advances and current challenges in salmon farming, with a particular focus on the search for sustainable and local alternatives for feeding the fish.
