Due to this, our study is dedicated to the comparative biometry of the Boops boops (Linnaeus, 1758) (Perci- formes Sparidae), between seven sites located on the Algerian coastline from north-east to north-west: El-kalla, Annaba, Skikda, Collo, Jijel, Algiers, Mostaganem. This study is made due to the total absence of reliable and exploitable information concerning the morphometric and meristic characteristics of this Algerian coast fish. The comparative study was carried out using thirty-six morphometric and meristic variables. The analytical approach carried out shows that environment factors have an influence and effect, not only on the diversity of living beings, but on the morphological variation in the same species. In addition, the statis- tical approach allowed a spatiotemporal evaluation of the biometry of the B. boops from the seven sites. As a first step, all the univariate statistical analyzes carried out, suggest significant differences between the seven sites, as well as a possible sexual dimorphism. Also, the analysis of variance at a fixed model classification criterion shows, with respect to the site factor, very significant to very highly significant differences between the seven sites for thirty variables out of thirty-six; for the sex factor, there are no significant differences for thirty-two variables out of thirty-six. Other models have been studied. Thus, in general, the general linear model MANOVA confirms the results obtained by the ANOVA. INTRODUCTION The biology or morphology of Boops boops (Linnaeus, 1758) (Perciformes Sparidae) has been studied in many areas: Tunisian coasts (Anato & Ktari, 1986), Moroccan (Zoubi, 2001a, b; Zoubi et al., 2004), Spanish (Zuniga, 1967), northwestern Mediterranean (Trangridis & Filippouzis, 1991; Sanchez-Velasco & Norbis, 1997), and Greece (Karpouzi et al., 2000). In Algeria, the study of the biology of the fish is limited in some works we quote that were carried out on the coasts of Bou-Is- mail (Chali-Chabane, 1988) and Béni-Saf (Djabali et al., 1991). On the coast of Skikda, data on the bi- KEY WORDS Boops boops; Mediterranean Sea; Algerian coast lines; ANOVA; MANOVA. DOI: 10.31396/Biodiv.Jour.2018.9.2.121.126
