(1981) [5], we prove analytically the stability of limit cycle periodic solutions. {W}e present numerical and computer simulations of the model.}, keywords = {{S}tructured population model ; {D}istributed delay ; {L}ocal stability ; {H}opf bifurcation ; {B}otulinum ; {T}ilapia}, booktitle = {}, journal = {{A}pplied {M}athematics and {C}omputation}, volume = {218}, numero = {17}, pages = {8226--8241}, ISSN = {0096-3003}, year = {2012}, DOI = {10.1016/j.amc.2010.12.084}, URL = {https://www.documentation.ird.fr/hor/fdi:010055796}, }
