“…This resulted in similar growth performance indices between sexes, despite the differences in VBG parameters between males and females. Growth differences among shrimp populations have been attributed mainly to latitudinal variations (Guerao et al, 1994;Guerao and Ribera, 1995). However, since there is no information on either seasonal or nonseasonal VBG parameters for P. elegans, we were unable to compare our findings with other studies.…”

“…Embryonic development (egg stages) was divided into three stages (Guerao and Ribera, 1995): Stage 1: Vitellus fills more than one-half of the egg volume, non-eyed eggs; Stage 2: Vitellus occupies no more than one-quarter of the egg volume, non-eyed eggs; Stage 3: Eyed eggs. Vitellus occupies less than onequarter of the egg volume, and decreases progressively until hatching.…”

SummARY: The seasonal growth pattern and reproductive biology of the rock pool prawn, Palaemon elegans, were studied in the southern Black Sea between February 2002 and January 2004. The seasonal von Bertalanffy growth parameters, computed from monthly length frequency distributions, were estimated as L ∞ = 47.8 mm total length (TL), K = 1. 115 year -1 for females and as L ∞ = 41.1 mm TL, K = 1.654 year -1 for males. The seasonal oscillation in growth rate for females (C = 0.904) was larger than it was for males (C = 0.586). The slowest period of growth corresponded to June in females and February in males. The size at sexual maturity for females (TL 50 ) was estimated as 33.8 mm TL. Ovigerous females were recorded from march to August and juveniles appeared in the benthic population in August. The ovarian development of the rock pool prawn was most probably initiated by photoperiod, whereas embryo development was accelerated with increasing water temperatures.Keywords: rock pool prawn, Palaemon elegans, seasonal growth, reproduction cycle, maturity size, Black Sea.RESumEN: Variación sexual en el crecimiento estacional y biología reproductiva de la quisquilla Palaemon elegans (Decapoda: Palemonidae) en el sur del Mar Negro. -Se estudia el modelo de crecimiento estacional y la biología reproductiva de la quisquilla Paleamon elegans en la parte sur del mar Negro, entre febrero de 2002 y enero de 2004. Los parámetros de crecimiento estacional por meses, calculados mediante el modelo de von Bertalanffy, se estimaron en L ∞ = 47.8 mm de longitud total (TL), K = 1. 115 año -1 para hembras y en L ∞ = 41.1 mm TL, K = 1.654 año -1 para machos. La oscilación estacional de crecimiento para hembras (C = 0.904) fue mayor que para machos (C = 0.586), y el periodo de crecimiento lento para hembras correspondió al mes de junio y el de machos en febrero. La talla de primera madurez sexual (TL 50 ) de las hembras se estimó en 33.8 mm. Las hembras ovadas se observaron entre marzo y agosto y la mayoría de juveniles fueron reclutados en el bentos en agosto. El desarrollo ovárico parece ser iniciado por el fotoperíodo, mientras que el desarrollo embrionario se aceleró con el incremento de la temperatura del agua.

“…Contributions to our knowledge of the population biology of P. adspersus in the Mediterranean have been provided by Guerao et al (1994), Guerao & Ribera (1995, 2000, and Guerao & Abelló (1996). In Minorca (Balearic Islands), the genus Palaemon is the most diverse among the palaemonids and some species enter into brackish waters where they show remarkable physiological plasticity (Pretus & Real, 1999).…”

Growth and reproductive cycle of the prawn, Palaemon adspersus were studied in Fornells Bay from April 2002 to March 2003. Samples caught using a lift net showed that abundance is markedly seasonal, with peaks in autumn and winter. P. adspersus showed distinct sexual dimorphism, the females being larger than the males. The K coefficient of the VBGF (Von Bertalanffy Growth Formula) was higher in the females (2.065 year −1 for females and 1.076 year −1 for males) and the same applies to L ∞ coefficient of the VBGF (47.8 mm in females and 34.14 mm in males). Ovigerous females were found from March to August. However, the low percentage of ovigerous females found in the study area suggests that reproduction and incubation do not occur at the study site. Also, as the ovary shows activity during the whole year cycle, it is not possible to distinguish a discrete reproductive period. RESUMENEl crecimiento y el ciclo reproductor de Palaemon adspersus fueron estudiados en la bahía de Fornells entre Abril de 2002 y Marzo de 2003. Las muestras obtenidas con una red por elevación indican una marcada variación estacional, con mayores abundancias en otoño e invierno. P. adspersus presenta dimorfismo sexual, siendo de mayor talla las hembras. Los parámetros de crecimiento calculados fueron superiores en hembras. El valor del coeficiente K de la VBGF (Fórmula de crecimiento de Von Bertalanffy fue 2.065 año −1 para las hembras y 1.076 año −1 para los machos. En el caso de L ∞ , fueron 47.8 mm en hembras y 34.14 mm en machos. Se han encontrado hembras ovígeras entre Marzo y Agosto. En cualquier caso, el bajo porcentaje de hembras ovígeras encontradas sugiere que la reproducción e incubación no se desarrollan en el área de estudio. Esto unido a que la actividad del ovario se mantiene durante todo el año no permite discernir un periodo reproductor claro.

“…The different abundances or dominances between sites (as it happens with the genus Palaemon) seems to be determined by the environmental characteristics and the biology of the species (feeding strategies -predation, reproduction cycle -recruitments, and ability to adapt to changes) (Forster, 1959;Guerao et al, 1994;Guerao, 1995;Guerao & Ribera, 1995;1996;Felicio et al, 2002;Manent & Abella-Gutiérrez, 2006;Bilgin et al, 2008). In this way, movements -migrations of P. adspersus have been related to water temperature (Hagerman & Østrup, 1980;Bilgin et al, 2008) but not always (Bilgin et al, 2009).…”

A study on the decapod assemblage inhabiting a shallow meadow of Cymodocea nodosa from the bay of La Goulette (Tunisia) was carried from February 2009 to February 2010. Monthly samples (with replicates) were taken in the morning and at night, with a small Agassiz trawl. In total 11699 specimens belonging to 41 species were caught. Significant day-night and seasonal changes are mainly related to movements (feeding) and recruitments. Higher abundance and richness were reported at night. Analyses rendered no significant relationships between the plant phenology and abundances and richness; neither between the total abundance and temperature, but significant correlations with a time lag of 3 - 4 months between these factors exist, which could be related with hatching and larval development period. The nocturnal and diurnal values in the diversity and equitability indexes are quite similar along the year (peaks in spring - early summer, minimum in autumn - early winter). This pattern is mainly due to the strong dominance of a few species, with maximum abundances during their recruitment events, whose seasonal and day-night changes have been determined. Besides, an overview of the decapods assemblage associated to this seagrass for the Mediterranean Sea has been carried out. The species can be divided into two groups (linked to the leaves and to the sediment). The differences in species composition between areas must be related to different sampling methodologies, feeding and reproductive strategies, but also to the layout and influence of the surrounding habitats.
