Physiological and genetic experimentation, breeding and maintenance of a variety of fish and amphibian species.
The Laboratory for Physiology and Genetics of Aquatic Organisms is designed for in vivo experiments on a variety of fish and amphibian species, including zebrafish, brown ghost knifefish, goldfish, rainbow trout, polypterus and amphibian species, such as the western clawed frog. It comprises 15 rooms over an approximate area of 500 m². The objectives of the Laboratory are to provide state-of-the-art core facilities for the breeding and maintenance of healthy aquatic organisms and for in vivo physiological and genetic experimentation. The core facility provides a service, unique in Ottawa, for the generation of transgenic zebrafish and mutant zebrafish using the CRISPR/cas9 genome editing technology. A major role of the Laboratory is to provide training to all users of advanced equipment for research on aquatic organisms. It serves over 100 students, research trainees and scientists. Users of the Laboratory for Physiology and Genetics of Aquatic Organisms perform cutting edge experiments in the fields of cellular and molecular biology, comparative physiology, developmental biology, endocrinology, neurobiology and behaviour, and genetics.
Production and maintenance of transgenic zebrafish and of mutant lines of zebrafish (using the CRISPR/cas9 technology)
Phenotype and transgene expression analysis: facilities for microscopy (including fluorescence microscopy) and microinjection for the production and analysis of transgenic fish, and for morphological analyses.
Areas for surgery (shared by all users) that include: a custom-built table for surgery; 6 wet tables, on which experimental chambers can be placed, supplied with water and with adjustable gas mixtures.
