Results of studies to validate satellite data and a research focused to know the consumer preference on some attributes of the mussels were part of the presentations of the members of the team Millennium Nucleus MUSELS.
A massive participation had the II Seminar of applied research to mussel farming, an instance designed to transfer the knowledge generated in the framework of various research projects, development and innovation related to mytiliculture industry.
The meeting, organized by Instituto Tecnológico de la Mitilicultura, INTEMIT, several exponents of the scientific field presented the progress during the course of their work.
Dr. Cristian Segura, Project Manager of INTEMIT says that this is the second version organized on the same line, the first took place in 2015, and it is an initiative originated as a response to the need proposed by some research centers.
“They indicated me about the need to disseminate the results of the research in Chiloé. Then we coordinated a joint activity with the cooperation and resources of each of the projects interested in this initiative. This would have a broad impact within the mussel farming public and a great attendance. “
The expert said that the seminar focused on promoting applied research, given wide circulation so that the final beneficiary can use the results in making decisions related to this productive sector. In addition, C. Segura indicated that the transfer in this instance is given not only in one direction, rather there is a mutual feedback.
“Researchers need feedback from producers to know what research lines we must follow and what challenges they have in the future. We need questions, and they have these questions”he says.
Participation of researchers of MUSELS
The topics discussed at the seminar were varied and aimed to understand the variables or environmental and productive patterns in the inland sea of Chiloé, with a look at the local and global changes of short and long term, considering the community as kay stakeholders to the sustainable balance of the mytiliculture activity.
In this context, three representatives of MUSELS, presented research that has developed within the framework of this interdisciplinary project.
The doctoral candidate at the Universidad Católica del Norte and student associated to MUSELS, Carlos Lara, presented the topic “Using satellite platforms in aquaculture ecosystems: the case of the inland sea of Chiloé”. In this presentation he explained that is developing a work whose objective is to validate the satellite data, specifically, data of the ocean color (chlorophyll) and the ocean surface temperature in the coastal systems in the Region of Los Lagos (inland sea of Chiloé).
“The use of satellite sensors has allowed tremendous progress in our understanding of biophysical processes in the world’s oceans. Despite this, its use is still limited, “he says.
The satellite data were compared using a collection of data collected in situ between the years 2003-2012. In this line, the observations have given some significant results, however, these must be taken with caution because it still requires corrections.
“Our results should be interpreted with caution due to the uncertainty caused by confounding factors such as the incident light, which requires a correction” said Lara.
The researcher says that these preliminary results provide an opportunity to understand the spatial and temporal patterns of the variability in communities of inland marine systems.
“The analysis of some oceanographic variables using satellite information, enables to understand oceanographic dynamics in time and space scales ecologically relevant. This capacity is important to understand the effects (direct or indirect) of the climate variability on the spatio-temporal fluctuations of the biological responses of the coastal ocean, “he says.
Dr. Felipe Vasquez, research associated to MUSELS, presented the talk “consumers respond to changes in attributes of mussels produced by the climate change?”. This talk was based on research that seeks to understand consumer preferences associated to various attributes of mussels, such as color, texture, size, presentation, price, among others.
“In particular we evaluated whether the attributes that will potentially be affected by climate change due to ocean acidification, are relevant from the perspective of consumers,” he says.
The study will determine the willingness to pay for each of the attributes considered, the total value of the resources for the consumers and the relative importance that the attributes affected by the climate change has for consumers.
While the talk “Biological, environmental and conceptual bases to assess the vulnerability of the aquaculture of Mytillus chilensis to the climate change projections” the Director of the Millennium Nucleus MUSELS, Dr. Cristian Vargas, exposed the research lines, the focus and the progress made by the Nucleus during these three years of work.
According to the Director, there is a growing global concern about the effects and possible interactions of multiple environmental stressors such as ocean acidification, global warming, pollution or deoxygenation faced by marine organisms. In addition, C. Vargas ensures that it is necessary to understand this process but together with the interactions of social and economic agents.
“It is necessary to incorporate environmental forcing together with the socio-economic in the management of marine resources. MUSELS works to generate pioneer scientific information regarding the environments and ecosystem services of which depend the industry, using interdisciplinary approaches in the research, “he explains.
He adds that “we have created pioneering information about the regimes of environmental variability in areas where the industry is developed in Chile, implementing experimental systems to evaluate the biological response of cultivated species and identifying the stakeholders in the socio-ecological system together with their capacities and preferences.”
To achieve its objective, MUSELS has defined three central scientific lines dedicated to (1) characterize the environmental variability in areas of bivalve farmer, (2) conduct experiments to understand the biological responses to multiple environmental forcings, and (3) study the human dimension and the socio-ecological system that is part of the aquaculture industry.
