“…Rochanaburanon and Williamson (1976) suggested that larval development of Crangoil crangon, unlike that of other caridean species, may be uninfluenced by environmental factors, whereas Criales (1985) found considerable morphological variation both in laboratory cultures and in field samples. This variability is widely observed in decapod crustaceans and reviewed by Christiansen and Anger (1990). especially for brachyuran and anomuran species.…”

Willfiihr-Nast J., H. Rosenthal, P. J. Udo, F. Nast, Aquar. Living Resour., 1993, 6, 115-137. Larvae of the African River Prawn Macrobracltium vollenlzovenii, indigenous to West Africa, were reared at various salinities (0-32°/00). A salinity range of 16-24°/00 was found most suitable with highest survival and growth, and lowest number and duration of instars. Freshwater was lethal already to zoea I -larvae. A mass culture experiment demonstrated the aquaculture potential of this Macrobrachium species. Larval rearing to postlarvae was possible applying the same methods as for M. rosenbergii. Detailed descriptions of rearing techniques are provided.Keywords: Prawns, Palaemonidae, Macrobrachium vollenhovenii, larval rearing, mass culture, salinity studies, egg incubation, survival, growth, larval and postlarval development. ~l e z a~e en laboratoire et etudes expCrimentales des elfers de la salinirk sur le dkoeloppement larvaire de la crevette de riviire africaine Macrobrachium vollenhovenii (Decapoda, Palaemonidae).Les larves de la crevette de riviere africaine Macrobrachiunr collenhovenii, espice indigene d'Afrique de I'Ouest, ont ete elevks a differentes salinites (0-32 O/,,). Une gamme de salinites de 16-24 O/oo a ete consideree la plus appropriee pour des taw; de croissance et de survie les plus importants, et pour des mues dont le nombre et la duree sont les plus faibles. L'eau douce etait deja letale pour les larves au stade zoe-I. Une ex+rience de culture en masse demontra la potentialite de I'aquaculture de cette espece de Macrobrachium. L'elevage larvaire jusqu'aux postlarves etait possible en appliquant les memes methodes pour M. rosenbergii. Des descriptions detaillees des techniques d'elevage sont donnees.

“…De estas submuestras se separaron y contabilizaron todas las larvas de crustáceos decápodos y en particular las de langostino colorado, que se preservaron en etanol (96%) para su análisis en laboratorio. La identificación taxonómica se verificó mediante las descripciones larvales de Pleuroncodes monodon (Fagetti & Campodonico, 1971;Bustos et al 1982), P. planipes (Boyd, 1960;Boyd & Johnson, 1963) y otras descripciones de larvas de distintos géneros de galateidos (Rayner, 1935;Gore, 1979;Christiansen & Anger, 1990;Seridji, 1995).…”

RESUMEN.Se analiza la distribución y abundancia de los estadios larvales de langostino colorado Pleuroncodes monodon en la zona norte de Chile, capturados entre 0 y 100 m, en cuatro cruceros oceanográficos efectuados en enero, mayo, agosto y octubre de 2003, en un área adyacente a la desembocadura del río Loa (20°40'-21°20'S). Se realizó un total de 20 estaciones oceanográficas y las muestras zooplanctónicas se obtuvieron mediante redes Bongo desde la superficie hasta 100 m de profundidad, registrándose además datos de temperatura, oxígeno disuelto y densidad en cada estación. Los máximos de abundancia se registraron en enero y agosto, y el mínimo en mayo. En sentido norte-sur, las mayores abundancias se encontraron en las secciones situadas en el sector norte. No obstante, en octubre se observó una distribución de abundancia más homogénea. En sentido costa-océano se determinó un patrón diferenciado, con una preferencia oceánica de los estadios zoea III-V y megalopa. Además, se observó una tendencia estacional de los focos de mayor abundancia larvaria asociados a las estaciones con temperaturas medias de 14,0-16,0°C y a concentraciones medias de oxígeno disuelto de 1,58-4,55 mL·L -1 .Palabras clave: Pleuroncodes monodon, Galatheidae, estadios larvales, variabilidad espacio-temporal, abundancia, norte de Chile. Seasonal variability in the distribution and abundanceof larvae of the red squat lobster (Decapoda, Anomura, Galatheidae) from Northern ChileABSTRACT. An analysis was made of the distribution and abundance of red squat lobster (Pleuroncodes monodon) larvae off the mouth of the Loa River, northern Chile (20°40'-21°20'S) during oceanographic cruises in January, May, August and October 2003. A total of 20 oceanographic stations were occupied, with zooplankton samples taken using Bongo nets towed from the surface to 100 m depth. Other data obtained at each station included temperature, dissolved oxygen, and seawater density. Maxima of abundance of these larvae were recorded in January and August, with a minimum in May. On N-S tracks the highest abundances were recorded in the northern sector. A more homogeneous distribution of abundance was observed in October. On E-W tracks a differentiated pattern was observed, where zoea stages III-V and megalopae occurred in the oceanic (westward) samples. Also, a seasonal tendency was noted, with foci of larval abundance associated with stations having average temperatures of 14.0-16.0°C and dissolved oxygen concentrations of 1.58 -4.55 mL·L -1 .

“…The additional zoeal stage found in this study can also be attributed to the fact that larval developments of decapod crustaceans can be highly variable in the number of larval stages and developmental pathways; a pattern that was however mainly attributed to caridean shrimps (Christiansen and Anger, 1990;Wehrtmann and Albornoz, 2003;Anger, 2006). Unfavourable environmental conditions such as low food availability, or unsuitable temperature and salinity, either in nature or in the laboratory, can modify the developmental sequence of decapod larvae (Thatje and Bacardit, 2000;Wehrtmann and Albornoz, 2003;and references therein).…”

“…Although less common, such variability has also been reported from brachyuran and anomuran species (Christiansen and Anger, 1990). Particularly in galatheids, it has been described for Galathea dispersa (Lebour, 1930), Pleuroncodes planipes (Boyd and Johnson, 1963), Pleuroncodes monodon (Faggeti and Campodonico, 1971), Galathea rostrata (Gore, 1979), and Galathea intermedia (Christiansen and Anger, 1990). The pattern of morphological plasticity in larvae, and larval developmental pathways was discussed as an advantage for species living in unstable environments (Wehrtmann and Albornoz, 2003;and references therein).…”

The larval development of the squat lobster Munida subrugosa from subantarctic waters of the Beagle Channel (Tierra del Fuego, Argentina) was studied under controlled laboratory conditions of temperature, salinity, and food supply. Developmental times, survival, and growth of larvae and early juveniles were investigated. Hatching of the entire brood always occurred during one night. Larvae were kept in 100ml individual bowls with filtered seawater at 8 ± 0.5°C and fed with Artemia spp. nauplii three times a week. Larvae passed through 6 zoeal instars and one megalopa. Previously, only five zoeal instars were known from this species. Mean cumulative durations of the zoeal stages I to VI were: 20.5 ± 2.5, 33.9 ± 4.1, 43.3 ± 5.4, 52.6 ± 5, 61.2 ± 3.9, and 83days, respectively. By adding the 28days that a single megalopa took to metamorphose to crab I stage, the complete larval development lasted 111days. Highest mortality occurred prior to the moult from the zoea I to zoea II stage (79.21% ± 18.65%) and during the moult from zoea VI to megalopa (92.86%). Carapace length was 1.64 ± 0.06, 1.52 ± 0.16, 1.57 ± 0.26, 1.64 ± 0.21, 2.11 ± 0.35, and 2.58 ± 0.19mm, for zoeal stages I to VI, respectively. Carapace length of megalopae and crab I instars was similar (2.85 ± 0.28 and the 2.84 ± 0.05, respectively). Unlike other subantarctic decapods, which show a tendency towards abbreviated larval development and/or some degree of endotrophy, M. subrugosa shows an extended planktotrophic larval development synchronized with short seasonal plankton production in austral summers.
