description Studies in a population of Tetraclita rubescens in Ellwood and Arroyo Hondo, California indicate that individuals of this species reach sexual maturity at the end of the second year of life but reproduction occurs in the third year. Recruitment seems to be lower, when compared with other barnacle species. The results suggest that successful recruitment occurs every two years.As expected, the mortality is extremely high in the Zero and one year old classes. Predation appears to be important as a factor controlling differential mortality rates. When the two study sites are compared no significant differences are found on the growth rate of barnacles. The younger age classes exhibit a period of rapid growth during the winter and early spring. Growth then tends to be fairly constant. Estudios realizados en poblaciones del cirripedio Tetraclita rubescens en Ellwood y Arroyo Hondo, California indican que los individuos de esta especie alcanzan la madurez sexual al final del segundo año de vida aunque la reproducción no ocurre hasta el próximo año. El reclutamiento observado es relativamente bajo cuando se compara con otras especies de cirripedios. Los resultados sugieren que un reclutamiento exitoso ocurre cada dos años.Como es de esperar, la mortalidad es extremadamente alta en la clase zero y en la de un año. La depredación parece ser importante como un factor que controla la mortalidad en diferentes clases de edades. Cuando se comparan los dos sitios de estudio, no se observan diferencias significativas en la tasa de crecimiento de los cirripedios. Las clases de edad más jóvenes exhiben un período de rápido crecimiento durante el invierno y principios de primavera. Posteriormente, el crecimiento tiende a ser más o menos constante.
