IFOP Repopulation and cultivation, stands out by organizing 2 Symposiums in the XLII Marine Sciences Congress

June 21st, 2023 Periodista Gabriela.Gutiérrez

Within XLII Marine Sciences Congress’s framework held between May 22nd and 26th at Universidad de Los Lagos (Campus Chinquihue, Puerto Montt). Two symposiums were held with Fisheries Development Institute (IFOP). Repopulation and Culture Department’s participation.

These symposia corresponds:

  • Repopulation and restoration in Chile: Lessons and challenges“, held on May 24th and coordinated by Dr. Francisco Cárcamo Vargas from repopulation and cultivation department.
  • Current state of aquatic ecosystems in Los Lagos Region: Present anthropic effects and future climatic change“, held on May 25th and coordinated by Dr. Luis Henríquez Antipa, from repopulation and cultivation department.

Regarding the first, it was made up of researchers from various institutions, including repopulation and cultivation, participating:

  • Dr. Francisco Cárcamo Vargas from IFOP repopulation and cultivation department, Puerto Montt. He presented “National and international context for repopulation and restoration in aquatic environmentsdevelopment .”
  • Armando Rosson Villalobos from Bitecma Ltda. Consultant. Presented “Experiences in gathering information, planting of invertebrates and brown algae of commercial relevance in AMERB”.
  • Dr. Juan Manuel Estrada from Quintay Marina Research Center, Universidad Andrés Bello. He presented “Advances in red sea urchin production for restocking and aquaculture.”
    MSc. Ana María Mora from SECOS, CiCC and Universidad Santo Tomás , Santiago. He presented “Repopulation of macroalgae in Chile: Biotechnological analysis and recommendations to achieve sustainability.”
  • Dr. Luisa Saavedra Löwenberger from the EULA Center from Universidad de Concepción and Packard Project. She presented “Restoration of floating huiro forests as a nature-based solution to climatic change.”
    Dr. Alejandra González Vásquez from the Department of Ecological Sciences of the Universidad de Chile. She presented “Chimeras: Super-algae for the repopulation, mitigation and adaptation to climate change”.
  • Denisse Torres Avilés from IFOP repopulation and cultivation, Coquimbo. She presented “Repopulation experiences and semi-quantitative modeling of management actions for the restoration of Lessonia trabeculata forests in AMERB Chungungo B”.
    MSc. Carlos Velásquez Gallardo from IFOP’s repopulation and cultivation department, Puerto Montt. He presented “Improvement of river shrimp stocks in times of drought: Experience with Cryphiops caementarius juveniles in the semi-arid north of Chile”.

The second symposium was attended by researchers from the IFOP Aquaculture Research Division:

  • MSc. Carolina Rösner Oyarzo from Environment Department , Chiloé. She presented “Lakes with aquaculture in the south of Chile, what has happened to it?
  • Dr. Javier Paredes Mella from Harmful Algae Research Center , Puerto Montt. He presented “Hotspots of HAB-forming species: Implications for aquaculture”.
  • MSc.Gabriel Soto Soto from the Putemún Coastal Station, Chiloé. He presented ” IFOP’s Oceanography Development : Tools Application for ecosystemic management in inland sea water bodies of Chiloé and Aysén.”
  • Dr. Heraldo Contreras Cifuentes from the Putemún Coastal Station, Chiloé. He presented “Diagnostic tools and prediction of the effect of aquaculture on sedimentary bottoms: Advances and research challenges”.
  • Dr. Pablo Leal Sandoval from RyC, Puerto Montt. He presented “Role and ecosystemic effects of small-scale multispecies aquaculture: Towards a high environmental level aquaculture”.

Both symposiums were highly attended and allowed a flow of questions that enriched the conversations about each of the topics addressed. Highlighting an active and constructive discussion in which the attendees asked key questions about IFOP’s role as an entity that provides information for the decision-making of the Government of Chile.

According to Francisco Cárcamo, the symposium “allowed, after many years, to bring together institutions and researchers who are developing repopulation and restoration actions, and to learn first-hand about the advances and multidimensional challenges of this type of actions. Both restocking and restoration can play a key role as conservation and artisanal fishery recovery strategies.”

On the other hand, Dr. Luis Henríquez highlighted 2 key aspects of the symposium “In a session open to the scientific community, the main results of major lines of study of the DIA were presented for the first time in a single session, which seek to demonstrate the state of of the ecosystems in terms of oceanographic knowledge, impacts on the benthic ecosystem, toxic algae blooms, polycultures as mitigation and conservation strategies, in addition to the knowledge acquired on lake ecosystems.

This symposium will allow to unify knowledge acquired in all the investigations of the Division in order to determine the state of the marine and freshwater ecosystems under anthropic pressure and generate environmental strategies of productive value for the country”.
