Gonadal cycle of Pteria sterna (>Gould, 1851) (Mollusca, Bivalvia) in Baja California, Mexico

Histological analyses were conducted on 376 organisms of Pteria sterna obtained from an experimental raft located in the Bay of los Angeles, Baja California, Mexico. From August 1987 to August 1988, seven bimonthly samplings were made that covered animals from two to fourteen months of age. We propo...

From August 1987 to August 1988, seven bimonthly samplings were made that covered animals from two to fourteen months of age. We propose a gonadal cycle with seven maturity phases and a histological scale of sexual maturity with nine conspicuous stages. The age of first maturity occurred in the females in October and in the males in December. Based on the observations, it is concluded that the population of P. sterna, settled on the experimental raft in August 1987, spawned continuously, with peaks in December, February and August.Se analizaron histológicamente 376 organismos de Pteria sterna obtenidos de una balsa experimental localizada en la Bahía de los Ángeles, Baja California, México. Se realizaron siete muestreos bimensuales desde agosto de 1987 hasta agosto de 1988, que cubrieron organismos de dos a catorce meses de edad. Se propone un ciclo gonádico con siete etapas de madurez y una escala histológica de madurez sexual con nueve estadios conspicuos. La edad de la primera madurez ocurrió en las hembras en octubre y posteriormente en los machos en diciembre. Con base en las observaciones, se concluye que la población de P. sterna, fijada a la balsa experimental en agosto de 1987, desovó continuamente, con picas en diciembre, febrero y agosto.Iniversidad Autónoma de Baja California1996-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/86810.7773/cm.v22i4.868Ciencias Marinas; Vol. 22 No. 4 (1996); 495-509Ciencias Marinas; Vol. 22 Núm. 4 (1996); 495-5092395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/868/790info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/8682024-08-22T17:01:36Z
