>Marbled crayfish are the only known decapod crustaceans to reproduce only by parthenogenesis. All individuals are female, and the offspring are genetically identical to the parent. Marbled crayfish are triploid animals, which may be the main reason for their parthenogenetic reproduction. Marbled crayfish are thus a model for the rapid generation of species.
>Because marbled crayfish are genetically identical, easy to care for, and reproduce at high rates, they are a potential model organism, particularly for studying development. A major drawback, however, is the long generation time (several months) compared to other research organisms.
Since they are genetically identical wouldn't it be easier to create a population of genetically modified crayfish? Say you inserted a gene to produce a protein in one of them. Then all of it's off spring would produce that protein as well. In time you could have enough crayfish to produce your protein in commercial quantities.
