Taxonomic Composition of the spring community of Tintinnids the shoreline of Aglou »Bay of Agadir,Morocco » [Composition taxonomique printanière du peuplement des Tintinnidés du littoral d'Aglou »baie d'Agadir,Maroc »]

It is a qualitative study whose objective is to determine the taxonomic composition of the community of the tintinnids the shoreline of aglou. a study has been carried out on the samples of the spring period (april,may and june) 2013,which has shown,by calculating of indices non-parametric of biodiversity,shannon-weaver (h'),margalef (dmg) and others,that the specific diversity in month of april (h'= 1.86) is more important in relation to the two months: may and june (h'= 1.02 and h'= 0.96 respectively). this result was confirmed by the taxonomic analysis which revealed the existence of 13 species of tintinnides in all the samples,dominated by the kind tintinnopsis; with a density of 1590 individuals,followed by stenosomella (306 individuals) and then favella (84 individuals) during the same period of the month of april. the study has revealed a regression of the specific richness of microzooplancton (tintinnides) during the spring period of the month april of june 2013.
