    Morfometria linear e geométrica do camarão Macrobrachium Jelskii (Miers, 1877) coletado no Rio São Francisco, no município de Itacuruba – PE
    (2019) Souza, Daniel Victor da Silva; Mendes, Renata Akemi Shinozaki; http://lattes.cnpq.br/2026358226342858; http://lattes.cnpq.br/7739502397733737
    The more than 200 species found are not Macrobrachium, a Macrobrachium jelskii (Miers, 1877) is one of 18 that can be found in Brazil. Known popularly as quiet shrimp, they are of great economic importance and are used as fishing and for the food of the riverside people. A technique used to improve the knowledge of the morphometric aspects of the species is used in geometric morphometry; by means of this it is possible to establish tactics for its handling and conservation. Thus, the studied shrimp were not presented in the municipality of Rio San Francisco, in the municipality of Itacuruba, in the semi-arid Pernambucano, in October 2018. After the establishment of a collection station, a sample collection was carried out with the aid of a hand. The compounds were removed in an ice cooler and taken to the Fisheries Biology Laboratory (LAPEq / UAST), with cephalothorax volume (total length (CT), length of cephalothorax (CC), and length of abdomen (CA); The photos were digitized in the TPSDig program, and the anatomical images were homologous in a standardized series and aligned in the MorphoJ program. The total length (CT) of the various sizes of 17 mm to 49 mm for a number of 13 mm to 56 mm for males. When comparing the linearity between CC x CT and CA x CT, a negative correlation was observed, showing negative (p>0.05), making that there was no sexual dimorphism in the relationships.A PCA analysis was published by 36.15% of the variation in the 1, 4 and 5 at the end of the face, and expanded 21.92% of variation, seen in frames 1, 2, 3, 6 and 7 at the extremity of the face, dorsal region and fr An analysis of variance was not possible to separate females and males (p = 0.2060).
