CONTROL OF THE PRODUCTION CHAIN
Écloserie marine de Gravelines Ichtus produces conventional or organic sea bass fingerlings (Dicentrarchus Labrax) and sea bass larvae (newly hatched eggs): annually 20 million selected fingerlings of 3 to 5 gr and 400 to 500 million larvae. EMGI distributes 15% of its production to Group farms, the rest is marketed abroad: Croatia, Greece, Italy, Spain. Fingerlings are delivered by fishponds trucks. The selected larvae are sold overseas to non-competing hatcheries.
Created in 1987, Écloserie marine de Gravelines produces sea bass fingerlings (Dicentrarchus Labrax) and sea bass larvae.
As a European specialist in this sector, we have been involved for many years in the field of genetic selection, which allows us to improve the well-being and growth of our fingerlings. A high standard of quality is achieved thanks to very strict health monitoring, regularly supervised by independent laboratories.
Very precise zootechnical controls and nutritional adequacy allow us to reduce the percentage of malformations, which is why we guarantee the quality of our fingerlings in order to offer our customers a standard of quality and constant traceability.
The water feeding the hatchery is filtered and then disinfected by ozone and UV. This water is used to feed all closed circuits of each spawning production unit until pre-enlargement.
In 2013, Ecloserie Marine de Gravelines joined the Gloria Maris Group. The stakes are numerous for the Group, the French sector can once again highlight its know-how internationally.
Our facilities include:
- 20 breeding pools
- 10 genetic selection pools
- 1 s specific incubation and hatching room
- 2 independent units of larval rearing
- 1 weaning unit
- 3 nursery units
- 1 zooplankton production unit (Artemia)
- 1 R&D unit
FROM BROODSTOCK TO SHIPPING
Sea bass fingerlings and sea bass larvae at the site of Gravelines
BROODSTOCK
In order to maintain our sanitary and genetic quality, we select our broodstock fish exclusively on the Gravelines site, under the control of veterinarians and geneticists from European research institutes.
INCUBATION
In a specific room equipped with a filtered and thermoregulated water circuit, 25 to 35 million eggs can be incubated. All eggs are selected, disinfected and identified before incubation. These techniques allow us to commercialize 100 million larvae a year all over Europe.
LARVAE BREEDING
The hatched larvae are transferred to one of two larval rearing units consisting of 12 to 6 pools. These units operate alternately in order to empty and clean the pools after the transfer of the larvae to the weaning unit.
WEANING
The weaning unit consists of 18 basins. 40 days after hatching, the larvae are transferred there and are weaned in about two weeks.
LA NURSERIE
The 3 nursery units are used after weaning.
From 60 days up to 150 days, fingerlings are sorted regularly to avoid cannibalism, allowing the preparation of homogeneous batches for deliveries.
Fingerlings are vaccinated and checked before each expedition. During the year, each fingerlings cycle is numbered according to the chronological order of release, the origin of the greenhouse, and the year of marketing.
We thus ensure the complete traceability of the fish, from broodstock to sale.
SHIPPING
According to the needs of our customers and the number of tanks in which the fingerlings will be unloaded, we can determine their exact quantity and weight without mixing the batches.
We work with serious and reliable professional carriers and have trucks equipped with 6, 8, 10 or 12 tanks with oxygen reserve and air suppressors, able to make long-distance deliveries with 6 or 7 days of transport.
