“…Though more research is needed in order to propose effective management measures before starting the exploitation of the resource, the implemented official closure of trawl fishery in the Greek waters every summer, coinciding with the reproduction period of the giant red shrimp, would be beneficial for the species stocks in the area. Also, an increase of the trawl cod-end mesh size from 20 mm (side), imposed by the EU regulation, to 28 mm (Ragonese and Bianchini, 1996) or more (Ragonese et al, 2002;D'Onghia et al, 1998b) for the deep waters, could reduce the participation of juveniles in the catch and enhance the stock sustainability.

SUMMARY: Data on the distribution, abundance and biological parameters of the giant red shrimp Aristaeomorpha foliacea were collected during a research survey in deep waters (600-4000 m) of the Mediterranean Sea at three locations: the Balearic Sea, the western Ionian and the eastern Ionian in early summer 2001. The shrimp was mainly found in the shallower zone (< 1000 m) of the eastern Ionian Sea. Few specimens were caught in the deeper waters of this region, with 1100 m being the lower limit of its distribution. This is the maximum depth reported for the species in the Mediterranean. At the other two locations, the species was scarcely caught and only in the shallowest zone (< 1000 m). In the area and depth zone of high abundance, 5 modal groups for females and 3 for males were distinguished using the Bhattacharya method. The recruitment seems to take place at the shallowest stations (600 m). More than 50% of adult females were in advanced maturity stages. The striking abundance differences of the species between the western and eastern locations may be explained by the different exploitation level of the deep waters (almost null in the eastern Ionian Sea and extensive more westwards). However, the distribution and biological characteristics of A. foliacea indicate a higher vulnerability to over-fishing comparing to the other commercial co-occurring deep-water shrimp Aristeus antennatus.Key words: Aristaeomorpha foliacea, distribution, biology, deep waters, Mediterranean. RESUMEN: BIOLOGÍA DEL MEDITERRÁNEO PROFUNDO: EL CASO DE ARISTAEOMORPHA FOLIACEA (RISSO, 1827) (CRUSTACEA: DECAPODA: ARISTEIDAE). -Se obtuvieron datos sobre distribución, abundancia y parámetros biológicos de la gamba gigante Aristaeomorpha foliacea durante una campaña de investigación en aguas profundas (600-4000 m) en tres localidades a lo largo del Mediterráneo: región Balear, Iónico occidental y Iónico oriental, que tuvo lugar en verano de 2004. Esta gamba fue encontrada mayoritariamente en la zona menos profunda (< 1000m) del Iónico oriental. En aguas más profundas de esta región (1100 m) se encontraron menos ejemplares, pero determinó el límite inferior de su distribución. Esta es la máxima profundidad registrada en el Mediterráneo para esta especie. En las otras dos localidades, esta especie fue escasa y solo se encontró en la zona menos profunda (< 1000 m). En el área y en la profundidad de máxima abundancia, se observaron 5 grupos modales de hembras y 3 de machos mediante el método de Battacharya. El reclutamiento parece que tiene lugar en aguas menos profundas (600 m). Más del 50% de las hembras adultas se encontraron en avanzado estado de madurez gonadal. Esta curiosa diferencia entre la parte más occidental y las localidades más orientales puede explicarse por el diferente nivel de explotación en las aguas profundas (casi nulo en el Iónico oriental e intensivo más al oeste). Sin embargo, la distribución y características biológicas de A. foliacea indican una vulnerabilidad alta a la sobre-explotación pesquera si la comparamos con o...

ABSTRACT. The "alistado shrimp" (Aristeus antillensis) is one of the targets of the trawling fleet operating since 2002 along the continental slope of the Brazilian Economic Exclusive Zone between 700 and 800 m depth. Catches of the species occur mainly in two small fishing grounds located on the east coast of Espírito Santo State (19-22°S). This paper aimed to obtain the first biological data for this species along the Brazilian coast. A total of 13,797 individuals were sampled aboard fishing vessels by observers on almost all fishing hauls, corresponding to 10 to 20% of the total catch recorded in the period. Males and females are sexually mature at 25.4 and 40.2 mm carapace length, respectively, based on an analysis of the proportions of individuals with fused petasma (males) and spermatophores in the thelycum (females). The proportion of impregnated females was higher than 80% year round, suggesting a continuous reproductive cycle, although preliminary information on gonadal development points to possible seasonal reproduction. In general, mature females, which attain larger sizes than males, dominate the catches (M:F = 0.12:1). However, populational groups including males and juveniles of both sexes occupy the fishing grounds in different periods of the year, probably reflecting migratory movements whose directions and driving forces are not completely understood yet. A depthstratified population structure by sex and size is hypothesized.
