Institut National de Recherche pour l'Agriculture, l'Alimentation et l’Environnement (INRAE)-STPEE (Fish nutrition Farms and platform) consists of 3 complementary platforms dedicated to nutrition of rainbow trout throughout the whole life cycle:

• Platform 1: Donzacq fish farm (17°C constant) has a feed manufacturing plant with a twin-screw extruder and wet labs, large (160 m3) and small scale (5000 and 200L) flow-through raceways, 36 50L tanks, 48 1m² tanks, 18 2m² tanks for juvenile nutrition.

• Platform 2: Lees Athas fish farm (7°C constant) comprises a hatchery for up to 400 groups of eggs; a UV-treated thermoregulated system to produce eggs and fry; 84 self-cleaning tanks for juvenile nutrition, 16 tanks of 200L, 32 tanks of 500L; 6 concrete tanks and 8 raceways of 12 to 20m3 for broodstock nutrition.

• Platform 3: 2 Specialized facilities, located at St Pée-sur-Nivelle, including (1) 2 independent RAS systems, each with 12 tanks, equipped with self-feeders to (i) monitor feeding rhythms, (ii) control feed distribution and (iii) evaluate the amount distributed.

The setup also enables feed choice experiments (2) 3 series of 6 cylindro-conical tanks in RAS with automatic faeces collector recognised by EIFAC as the most valid method for in vivo evaluation of apparent digestibility coefficients (ADC) of diets and ingredients. INRAE-STPEE can undertake all types of nutrition research experiments, using rainbow trout (freshwater) as the main study model. It has been actively used in experiments from EU projects from the 5thFP to H2020 (PEPPA, RAFOA, GUT INTEGRITY, FINEFISH, AQUAMAX, PROMICROBE, LIFECYCLE, AQUAEXCEL, ARRAINA, AQUAEXCELAQUAEXCELAEXCEL3.0). An AQUAEXCELength to the experimental infrastructure is the proximity of nutrition researchers which provides a healthy environment for scientific interaction and exchange.

Bioresources available

On-site access to rainbow trout is available on our fish nutrition platforms. The full life cycle of rainbow trout is also available, allowing experimental design with broodstock, alevin and juvenile nutrition.

Support offered

In addition to the above information, technical support for daily experimental work and technical help for samplings will be provided to all users. For specific needs, INRAE scientists using the infrastructures (genetics, nutrition, physiology, pathology) will assist users for experimental design and data interpretation.

Modality of access

Each user is expected to stay 12 weeks (duration of a typical nutrition trial).

Unit of access: tank/week

Type of access: on-site
