Abstract
In this mini-review we provide an up-to-date overview of the delivery methods that have been used for CRISPR/Cas9 genomic editing in crustacean species. With embryonic microinjection as the main workforce for delivering CRISPR/Cas9 reagents, biologists working with crustacean species have to tackle the technical challenges involved in microinjection. We use examples of three crustacean species (the branchiopod Daphnia, amphipod Parhyale hawaiensis, and decapod Exopalaemon carinicauda) to provide a technical guide for embryonic microinjection. Moreover, we outline two potentially useful new techniques for delivering CRISPR/Cas9 components into crustaceans, i.e., Receptor-Mediated Ovary Transduction of Cargo (ReMOT Control) and electroporation.
