Exposición y vulnerabilidad a mareas rojas de comunidades rurales costeras en la Isla Grande de Chiloé
(Universidad de Chile, 2020-10)
, Queilén y Quemchi son las comunas con mayor vulnerabilidad, pero con baja exposición, mientras que las comunas del centro de Chiloé tienen una exposición potencial alta, debido a su área destinada a acuicultura y su capacidad de retención. Se observó una...
Harmful algal blooms (HAB) have a great social and economic impact in the Chiloé inland sea. The social theory of risk makes it possible to identify determinants of the degree of impact that go beyond the risk events to include dangerousness, exposure, vulnerability and uncertainty. In this title seminar, the risk of rural Chiloe communities to be impacted by HAB was analyzed, estimating their exposure, based on the use of coastal marine space and the results of a hydrodynamic model. In addition, their economic vulnerability was analyzed through indices generated from the Casen survey (2017) and a social-ecological survey (2019). The results of the model showed that the areas with the highest retention coincide with the distribution of mussel farming centers, the greatest diversity of uses, and that the degree of retention of each area is related to the topography. Quellón is the commune with the highest risk, and Chonchi the second, while Ancud is the one with the lowest risk. On the other hand, Queilén and Quemchi are the communes with the greatest vulnerability, but with low exposure, while the communes of the center of Chiloé have a high potential exposure, due to their area destined for aquaculture and their retention capacity. A decrease in the dependence of rural communities was observed when comparing the CASEN and social-ecological surveys. Elements of uncertainty are identified in the knowledge and projection of HABs, in a context of socio-economic and environmental changes. It is proposed that holistic and integrative approaches, such as the social theory of risk and social-ecological systems, spatially, are useful conceptual frameworks for environmental management and socio-environmental problems....

Evidencia de Piscirickettsia salmonis y Yersinia ruckeri en truchas arcoíris (Oncorhynchus mykiss) en cultivo de balsa jaula en el lago titicaca en el distrito de pomata departamento de puno (Perú)
(Universidad de Chile, 2016)
La acuicultura en el Perú está creciendo marcadamente en los últimos años, siendo Puno uno de los Departamentos con mayor producción en el cultivo de truchas arcoíris (Oncorhynchus mykiss). A consecuencia de este crecimiento y la falta de producción...
Aquaculture in Peru has grown sharply in recent years, Puno is one of the departments with most production of rainbow trout (Oncorhynchus mykiss). As a result of this growth and the lack of national egg production, its import from different countries has increased. In this regard, there is a high risk of introduction of infectious agents transmitted by vertical transmission as Piscirickettsia salmonis, which is currently the biggest health problem associated with high mortality rates in Chilean salmon farming. P. salmonis is a pathogenic bacterium that was first isolated in 1989 and is the causative agent of Piscirickettsiosis disease. Currently in the cultivation of rainbow trout in Peru, the main disease in trout is yersiniosis, which is caused by the Yersinia ruckeri infectious agent, which generates high economic losses. However, health studies have been restricted to the area of Junín and not to Lake Titicaca, particularly in Puno, where 90% of the production of this species is concentrated. The aim of this research was to determine the presence of P. salmonis and Y. ruckeri pathogens in Puno, in the District of Pomata. 43 fish were selected of 250 g, at commercial stage at harvest time, with no clinical signs of disease and that were cultured in cage raft. In all animals the following were sampled: liver, spleen and kidney according to the procedures established by the OIE. Reaction technique of nested polymerase chain (PCRA) for detecting P. salmonis was performed using two sets of primers: Eub-A, B-Eub, and PS2S, PS2AS resulting amplification product of 467 bp. For Y. ruckeri PCR with primer YER8, YER10 was used, which generates a product of 575 bp. Bacteria were detected in all three types of samples. In the case of P. salmonis 9,3% of individuals tested positive and the percentage of distribution of organs was: 6.9% in liver, 4.6% in spleen and 6,9% in kidney. For Y. ruckeri only one individual was positive (2.3%) for all organs. This study is the first evidence of the presence of P. salmonis in Perú and of Y. ruckeri in Lake Titicaca, in the District of Pomata....
