About The Author

The laboratory of Marine Genetics Physiology (FIGEMA) tries to understand the responses of marine organisms to changes in their environment from their physiology to genetics. It focuses on researching problems applied to aquaculture, but also of an ecological nature.

Specifically, we studied how the physiological capacities and traits associated with growth are modulated by factors: 1) external environmental factors (such as food availability and quality, thermal and oxygen changes) and internal (such as developmental, reproductive or nutritional status, and presence of diseases); 2) genetic, as effects of polymorphisms in particular loci, individual genotype, expression of genes and polygenic inheritance on the variation of the characters.

In our studies we use research tools at different levels of biological organization: molecular, individual, behavioral and population.

Through our research we aim to support aquaculture through the generation of marine organisms with improvements in their physiological capacities associated with growth, reproduction, stress response and immune response.

                       

Genetic Selection For Fast-Growing Traits Among Haliotis Rufescens Mollusks

The increase in the human population and the overexploitation of fishery resources means that aquaculture is becoming more important. Projections indicate that all the increase in aquatic animal supply will be completely attributed to aquaculture, where cultured mollusks will dominate by 2030. Among cultured mollusks, abalones have one of the highest commercial values. There exist ∼100 species of abalones, among which 25 reach an adequate size to be commercially exploited. Large abalones, such as the red abalone Haliotis rufescens, primarily...
