Fisheries Development Institute (IFOP) strategic role is based on its capacity to generate, develop and transfer useful knowledge, which allows our country and national industry to position itself, competitively and sustainably, in aquaculture and fishing , especially for high public value research.
IFOP develops integral consulting for decision making in Fisheries and Aquaculture and research projects on status and evaluation of sustainable exploitation strategies, estimation of total allowable quotas of commercial interest resources, evaluation and monitoring of benthic resource management areas, hydrobiological health programs, environment and repopulation and crops, and an aquaculture and fishing knowledge node with emphasis on digital preservation, access and visibility of knowledge.
Thanks to IFOP’s work, the State has necessary information to manage and regulate resources capture, establish fisheries integrated management, deploy a management model and technical assistance, develop aquaculture and sustainable fishing, and safeguard the documentary scientific heritage.
1 Management and Monitoring Program for red tides in Los Lagos, Aysén and Magallanes regions
Due to toxic microalgae frequent proliferation in southernmost regions of the country, it is necessary to have rapid detection system in order to provide early warning to users related to extraction and culture of both filtering and carnivorous shellfish (Concholepas concholepas ).
This program is presented as a permanent activity, which takes place annually. Contemplating Subprograms differentiated sampling in relation to the needs of each geographical area, adapting consequently the sampling frequencies and distribution of the stations according to each sector particular realities. Under this criterion the study is structured in 3 subprograms: a) Regular Monitoring; b) Surveillance and Monitoring; and c) Raúl Marín Balmaceda Monitoring.

Since 2013, mussels larval monitoring activity has been developed in mussel farming interest areas. This program is considered as a permanent activity that will allow the authority to have timely information to take actions to protect the activity. In the present stage of the program the methodological aspects regarding the taking of samples and larval identification are maintained. In addition, the sampling coverage is extended, including 13 stations in the Los Lagos region and 11 stations in the Aysén region, aimed at elucidating areas of larval availability.
This environmental study of Araucanos and Chilotes lakes, in which aquaculture is developed, is aimed at obtaining limnological characteristics information of both the water column, sediment and surface currents. With this background, it is possible to make updated estimates of carrying capacity and trophic status of studied lacustrine systems, to provide information that allows sectoral authority to adopt decisions to protect aquatic systems where aquaculture activities are carried out, with a view to sustainable aquaculture and integrated management perform to control lake systems eutrophication.
- Araucanian Lakes: They are located at Los Andes mountain western slope, range between 39 ° S and 42 ° S. They are of volcanic glacial origin, deep, with large size and water volume. Due to their thermal regime, they are classified as temperate monomictics (mixed once a year). They have been described with high transparency, low nutrient input and low primary production. Its hydrological regime is snowy pluvio. The main anthropogenic activities in their river basins are: cities, livestock, dairy, agriculture, aquaculture and hydroelectricity.
- Chilote Lakes: They are located on Chiloé Island, they are of tectonic glacial origin. They are classified as dystrophic lakes (high contribution of colored dissolved organic matter, including humic and fulvic acids), which gives its characteristic brown color. They are small and low depth systems. They present low transparency and phytoplankton production, and high bacterial production. The hydrological balance is subject to rainfall regimes, being the native forest and peat, the main collectors of rainwater. It is highly vulnerable lakes. The main uses of soils associated with their basins are: native forest, grazing meadows, mixed forests, as well as industrial and aquaculture activities.
During 2010, the presence in Chile of D. geminata microalga, commonly known as didymo, was detected. This native species from northern hemisphere, is recognized for its invasive characteristics, was declared a pest in our country in 2010 maintaining this condition to date. Since that date, the Undersecretariat of Fisheries and Aquaculture (SUBPESCA) and the National Fisheries and Aquaculture Service (SERNAPESCA), mandated by the Regulation on Hydrobiological Pests (DSN ° 345/2005 and its amendments), maintain a constant activity of prospecting in new sectors, and the monitoring and surveillance of areas with microalgae presence. In this sense, the Fisheries Development Institute (IFOP) continues with the prospecting and monitoring in order not to neglect sectors that border declared pest areas, and thus quickly identify new outbreaks or new distribution areas of the microalgae. In addition, it maintains a seasonal surveillance of abundance variations related to its proliferation, analyze its effect on ecosystems with its presence and maintain a program of dissemination of results.
