The Blond des Flandres
Any domestic species has a great number of races, well adapted to different hearts, and different uses. All have been obtained :
- by selection in a population, with a good choice of breeders, generation after generation.
- by crossing with external animals which have good traits.
It is also the case of "Blond des Flandres" snail
In France, there are two kinds of snail consumers : the first ones who like the Burgundy, and generally big snails, for a traditional use, and the other ones who prefer the Petit-Gris.
Breeders have to choose between these two types. It is not possible, today, to rear the Burgundy with a good profit. Therefore this snail is replaced by Helix aspersa maxima, the Gros-Gris, which is a cousin with the Petit-Gris, from Algeria. Unfortunately the Gros-Gris has a very dark mantle unlike the two other snails, in opposition to our habits.
So my idea is to create a snail which looks like the Burgundy but easy to rear as the Petit-Gris. That is the "Blond des Flandres"
|Petit-Gris (10 g on average)||Blond des Flandres (20 g on average)||Gros-Gris (20 g on average)|
|These three snails belong to the same species Helix aspersa|
Year after year, I have crossed and selected Petit-Gris, Helix aspersa aspersa, mainly for two traits: shell size and color.
In 1998, 50% of my animals had a shell diameter larger than 40 mm ( 1.57 in ), and 75% had an uniform ochre shell (unicolor). One had a shell diameter of 54 mm ( 2.12 in ), I think it is the world record for this species.

Note: we cannot say that "Blond des Flandres" is already a breeding race. Traits are not fixed and experiments have to be conducted in commercial conditions. But I think it is in a good way !
The "Blond des Flandres" is not alone ! I know an other attempt to select a breeding strain :
the "Jaune de Gand" of Prof. André De Grisse ("Gentse Gele" in Dutch)
It is a strain of "Gros Gris", selected for 10 years, with a yellow shell, as "Blond des Flandres".
