The deep water rose shrimp, Parapenaeus longirostris is a commercial species for the trawl fleet that operates in the Gulf of Alicante. Despite its importance, there were no biological studies on the species for that area. This study presents results on the life cycle of the species, shedding light on certain crucial aspects. Data were obtained from monthly samples taken from commercial catches landed in the port of Santa Pola from 2001 to 2006. The fisheries in the studied area show a decreasing trend, both in number of vessels targeted on the species, and in landings, since 2001. The species shows a sexual size dimorphism, with a negative allometry of relative growth that is more pronounced in males and thus results in lower sizes of males than of females. Estimate produced from VBGF parameters gave higher K values for males than for females, indicating that males would reach 13.2 mm CL in the first year and females 14.8 mm CL, which would represent a maximum life expectancy of 4 and 6 years, respectively. The reproductive period, based on the percentages of maturity and GSI development, was found to range throughout the year, with some peaks of activity especially in summer. The size at first maturity (L50) of 25.6 mm for females indicates that maturation will have to occur from the second year of life. La gamba blanca Parapenaeus longirostris es una especie comercial para la flota de arrastre que opera en el Golfo de Alicante. A pesar de su importancia, no existían estudios sobre la biología de la especie en esta área. Este trabajo presenta resultados sobre el ciclo vital de la especie, aclarando algunos aspectos importantes. Los datos fueron obtenidos a partir de muestreos mensuales realizados sobre capturas comerciales desembarcadas en el puerto de Santa Pola durante los años 2001 al 2006. La pesquería en el área de estudio muestra una tendencia a la disminución, tanto en el número de embarcaciones dedicadas a su captura como de sus desembarcos, desde 2001. Los resultados muestran un dimorfismo de tallas por sexos, con una alometría negativa de crecimiento, mas destacada en los machos que alcanzan tallas menores que las hembras. Las estimaciones realizadas de los parámetros de la VBGF dan unos valores de K mas elevados en machos que en hembras, con lo que los machos alcanzarían los 13,2 mm de CL en el primer año y las hembras los 14,8 mm de CL en el mismo tiempo, lo que podría representar una esperanza de vida de cuatro y seis años respectivamente. La época de reproducción se ha definido en base a los porcentajes de madurez y la evolución del IGS, desarrollándose a lo largo de todo el año, con especial intensidad en primavera-verano y en otoño. Las tallas de primera madurez (L50) de 25,6 mm para hembras, indican que la maduración tendría lugar a partir del segundo año de vida.
