The present invention relates to a device for fixation of larvae and growth of juveniles of the stalked barnacle Pollicipes pollicipes, as well as to the process of larval attachment and development of juveniles of P. pollicipes, which are important phases for the production of this crustacean. The device of the present invention comprises a main element (1) and a fastening means (2) allowing its insertion into a suitable substrate and further collection and removal along with the attached larvae and/or juveniles of P. pollicipes. The present invention allows to successfully obtain larval attachment and subsequent metamorphosis, survival and growth of juveniles of P. pollicipes on a natural or artificial substrates. On the other hand, it has a low associated cost and its process of use is simple and efficient. This invention has applications in aquaculture and aquariophilia, in the scientific investigation of this species and on its conservation.
