...did a study on the crayfish market of Miarinavaratra. Crayfish are an important part of the Malagasy diet. Almost all crayfish for consumption in Miarinavaratra, are caught in high numbers in the Fandriana-Marolambo forest. They are sold locally, and/or exported to the capital Antananarivo where good money is being paid for large specimens. Crayfish are highly dependent on a healthy state of their forested habitat, but due to habitat loss, the population seems to diminish.
WWF is concerned that a drop in crayfish numbers may lead to a population that is too small to sustain itself, which will have catastrophic effects on the existence of the crayfish species.
