Lab-grown crayfish take over Belgian cemetery

(ORDO NEWS) — Experts from the Flemish Institute for Nature and Forest Research noted that the city cemetery in Antwerp (Belgium) was captured by crayfish grown in the laboratory.

We are talking about marble crayfish that do not exist in nature. According to unofficial data, they were bred in the laboratory by German pet traders at the end of the last century. Outwardly, the creatures resemble crayfish that live in Florida (US).

Marble crayfish have one feature: they are able to reproduce without mating, since they are parthenogenetic. All offspring are females and share the same genetic code. As a result, uncontrolled proliferation of creatures is possible. It seems that this happened in Antwerp.

Experts believe that someone has decided to release their pets into the reservoir. It is now impossible to solve the problem of uncontrolled reproduction in any way: any attempt is tantamount to draining the ocean with a bucket. When the population in the aquarium becomes too large, owners see nothing wrong with their pets mastering much larger water areas.

Cancers pose a threat to the local ecosystem, as they feed on absolutely everything that they can handle. Plus, they can easily cover a distance of several kilometers in a day.

Marble crayfish are 10 cm long and are nocturnal. They often leave the body of water, crawling on land. Seven years ago, the European Union banned not only the release of creatures into natural reservoirs, but also contain them. Because of the genome’s identity, it is impossible to figure out where the crayfish came from in the cemetery.
