LPGP

The researches developed at INRAE LPGP are mainly aiming at investigating fish biology in the perspective of supporting a more sustainable aquaculture.

The scientific goal og LPGP is the study of the main physiological functions of fish: growth and reproduction.

INRA LPGP is currently hosting 3 research groups:

• Growth and Flesh Quality
• Sexe, Oogenesis and Behavior
• Sexual Maturation, Cryoconservation and Regeneration

The LPGP fish facility is an indoor structure based on recirculation systems which allows to control all the rearing parameters. The LPGP fish facility has the required level of biological safety for rearing genome-edited fish (trout, zebrafish, medaka, pike..) over a complete life cycle. It is equipped with:

• 20 independent recirculating water systems in 10 rooms (500m2).
• A quarantine room.
• A behavioural study room with camera on each tank.
• More than 100 large tanks for trout and 1,000 small tanks for model species.
• Room dedicated to eggs microinjection for production of transgenic or genome edited fish.

Four full-time permanent technical staff work on site, highly skilled in fish protocols in genome edition, physiology (reproduction, growth), and welfare.

The LPGP fish facility offers an array of services:

• production of transgenic or genome edited trout (GET service) that includes egg injection, genotyping and fish rearing up to reproductive stage. Training the users to genotyping and microinjection.
• The possibility to perform germ cell grafting (GCGraft service) into recipient embryos and the rearing of the surrogate fish up to maturation.
