Morphometric relationships of two commercial deep-sea shrimp species from French Guiana

Values for selected morphometric relationships are extremely important for shrimp fisheries management. This information, however, does not exist for some deep-sea shrimp species which are of interest to fisheries. A variety of weight-weight, length-length and length-weight relationships have been estabelished, therefore, for two commercially important species of deep-sea shrimp from the continental slope off French Guiana (western central Atlantic), i.e. the solenocerid shrimp Solenocera acuminata (orange shrimp) caught on the upper slope (about 200 m) and the aristeid shrimp Plesiopenaeus edwardsianus (scarlet prawn) widely distributed on the middle slope (from 400 to 900 m). This paper represents the first contribution on the morphometric relationships of these two deep-sea shrimp species.
