Eco - Hatcheries

Home / Environment / Eco - Hatcheries

This industry has experienced a growing demand for products guaranteeing food safety, the necessity of maintaining the industry’s image at a high international standard and the efficient environmentally-sustainable production of fish resulting in high quality products. The above are just some of the reason why Marine Farm has invested in the latest recirculation and water treatment technologies, thus leading the evolution of the Chilean aquaculture industry.

With over 15 years in the area, Marine Farm developed Los Chilcos recirculation Eco-hatchery project in 2005 at the edge of Los Chilcos estuary, approximately 3 km from the main road between Villarrica and Pucon. It also developed the La Union recirculation Eco-hatchery in the Puyuhuapi area in the Eleventh region. The stages from egg incubation to smolt take place at these hatcheries.

In aquaculture, water recirculation is the process that recovers and reuses water being thrown away in traditional open-flow systems and disposed for having lost one or more of the attributes that make it suitable for cultivation processes.

This type of hatchery significantly contributes to the protection of the environment since it has the advantage of achieving substantial reduction of effluents and waste material released into the environment by more than 90% compared to those emitted by conventional systems.

Recirculation hatcheries have also other advantages such as easily controlling environmental and water quality parameters (temperature, oxygen, pH, carbon dioxide, ammonia, etc.) through the use of biological filters. This generates optimum fish growth and disease prevention and important results regarding hygiene, health, growth rate, feed utilization, and the natural processes of nutrient metabolism.

Furthermore, this type of technology has allowed savings in energy as well as water consumption by reducing the use of water flow required for an aquaculture facility due to the reuse of more than 99% of water. This technology has obtained higher growth rates than in nature or in flow-through systems, better working conditions and better control of pathogens in the water entering the system. This enables the production of fish in a disease free environment permitting a constant market supply of high quality alevins and presmolt products, among others.
