“…Nevertheless, it is necessary more studies to confirm this tendency, since others factors may be related to this choice. The preference for one specific substrate has been reported in other decapods (SÁNCHEZ 1997, RÖNNBÄCK et al 2002, QUELLETTE et al 2003. It is possible that the T. panoplus preference may be an anti-predator strategy once on the gravel these animals became camuflaged (similar size and color).…”

This work describes the behavioral repertory of Trichodactylus panoplus von Martens, 1869, based on the animals' diel activity and the possible substrate preference under laboratory experiments. Three experimental replicates were carried out, each using six animals (three males and three females). There were four periods of observation a day, with a total of 864 observation sessions and 144 hours of experiments. A total of 15 behavioral acts divided into five categories were recorded: feeding, exploration of the environment, immobility, social interaction, and self-grooming. The obtained results suggest that T. panoplus has greater activity during the night (p < 0.05), yet without showing an activity peak. In addition, the acceptance of food does not depend on the photoperiod. There was a significant preference for gravel as the chosen substrate. The Morisita index indicates an aggregated distribution of these animals, confirming their preference for substrate with gravel. The increase in activity at night and the preference for substrate with gravel, which can be used to disguise these individuals, would be associated to some anti-predator strategies of these crabs against visually orientated predators

“…Preferences for a particular substratum and vegetation appear to be dominant factors that govern settlement in postlarval and juvenile penaeids (Dall et al, 1990;Sánchez, 1997;Pérez-Castañeda and Defeo, 2001). …”

SUMMARY: The population structure of the penaeidean shrimp Xyphopenaeus kroyeri was studied in Ubatuba Bay, Ubatuba, São Paulo, Brazil. The period and site of juvenile recruitment were monitored using a monthly sampling design with eight fixed areas (transects) from September 1995 to August 1996. The population structure was assessed using size frequency distributions (based on carapace length) for each month and sampling area. Females were significantly larger than males, suggesting a differential growth between sexes. The very low occurrence of large adults in the Bay can be related to offshore migration for reproduction. Recruitment occurred throughout the year, with a peak during the summer, when the highest recruitment rates were obtained along inshore transects. The present investigation revealed valuable information on the biology of the species mainly in the study region, which is considered a nursery ground for juveniles of X. kroyeri. The species showed an important variation from the typical life cycle that it is assumed to hold over its entire range and X. kroyeri should be classified as having a life cycle different from that proposed previously in the literature, i.e. the juveniles prefer inshore areas instead of estuaries. Some suggestions for the seabob fishery management are proposed as an alternative for minimising the impact during the harvest period and adjusting the protection schedule.Key words: population structure, recruitment, Xiphopenaeus kroyeri, Penaeoidea. RESUMEN: ESTRUCTURA DE LA POBLACIÓN DEL CAMARÓN SEABOB XIPHOPENAEUS KROYERI (HELLER, 1862) (CRUSTACEA, PENAEOIDEA) EN EL LITORAL DE SÃO PAULO, BRASIL. -La estructura de una población del camarón Xiphopenaeus kroyeri en la Bahía de Ubatuba, Ubatuba, en Brasil, fue estudiada, con énfasis en el periodo y área de reclutamiento de juveniles. La estructura de la población fue monitoreada a través de muestreos mensuales en ocho áreas diferentes (transectos) de la Bahía, entre septiembre de 1995 y agosto de 1996. La estructura de la población fue determinada por medio de la distribución de las frecuencias de talla (basada en la longitud del cefalotórax) para cada mes y área muestreadas. Las hembras alcanzaron mayores tallas que los machos sugiriendo un crecimiento diferencial entre sexos. La ocurrencia muy baja de adultos de mayor tamaño en la bahía se puede relacionar con la migración para la reproducción mar adentro. El reclutamiento ocurrió preferentemente en los transectos costeros y en casi todos los meses, con un pico durante el verano. Los resultados muestran que la Bahía de Ubatuba puede ser considerada como una zona de cría de los juveniles de Xiphopenaeus kroyeri. Se propone un nuevo tipo de ciclo vital para esta especie, en el que, a diferencia de lo propuesto en trabajos anteriores, los juveniles prefieren las áreas costeras en lugar de las estuáricas. Se hacen algunas sugerencias para la actividad pesquera sobre esta especie de camarón a fin de reducir al mínimo el impacto durante el período de pesca.

“…Their use of the habitat also varies, as for example penaeid shrimp during the various phases of epibenthic postlarvae and juveniles in estuarine ecosystems (McTigue & Zimmerman, 1991;Sánchez, 1997;Pérez-Castañeda & Defeo, 2001;Beseres & Feller, 2007). The brachyurans Platychirograpsus spectabilis, Armases cinereum and Goniopsis cruentata collected in SAV were small in size, as the adults are semi-terrestrial (Schubart et al, 2002;Álvarez et al, 2005).…”
