Larval development of the subantarctic squat lobster Munida subrugosa (White, 1847) (Anomura: Galatheidae), reared in the laboratory

Abstract: 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 we… Show more

“…Several studies have demonstrated that wild crustaceans can be fed with TetraColor ® . For example, the squat lobster fed exclusively with TetraColor ® can develop its ovary in a 4-month experiment [ 7 ] and successfully incubate embryos during their whole development [ 54 ]. Palaemon argentinus shrimp feeding on these commercial pellets can grow its midgut gland ( Fig 1 ), and molt regularly (pers.…”

“…Larval dispersal is crucial for connectivity and colonisation through migration in deep-sea environments. Specific larval development characteristics are unknown for M. isos, M. endeavourae and M. gracilis but based on egg size, a 'regular' (not abbreviated) planktotrophic larva is inferred as in other Munida species (Baba et al, 2011), The only complete larval development study was conducted for a congeneric species, M. gregaria, with a PLD that may reach 83 days at a rearing temperature of 8 • C in the laboratory (Pérez-Barros et al, 2007). The potentially long PLD of the three Munida species that lasts for perhaps several months is but one of various possible explanations for the panmixia observed in the study region.…”

“…En el Golfo San Jorge, desde la aparición de las primeras zoeas en el plancton hasta la aparición de decapoditos transcurren unos 80 días. Si bien no fueron realizados experimentos tendientes a determinar la duración del desarrollo larval, la aproximación obtenida de la distribución temporal de los estadios sugiere que los tiempos de desarrollo no serían muy diferentes de los observados en experiencias de laboratorio conducidas a 8°C (± 0,5°C) (Pérez- Barros et al 2007). Esta temperatura es similar a la que se registra en el área central del Golfo San Jorge en los meses de agosto y septiembre, según registros locales e información suministrada por el Servicio de Hidrografía Naval.…”

“…El número de zoeas identificadas es igual al informado por Rayner (1935), Roberts (1973) y Lovrich (1999. Sin embargo, difiere de los cuatro estadios identificados en muestras de plancton por Thatje et al (2003) e incluso de los seis estadios obtenidos en laboratorio por Pérez- Barros et al (2007). Dado que las identificaciones de los estadios se basaron en los trabajos de Rayner (1935) y Roberts (1973), resulta difícil identificar un sexto estadio, cuyas características diferenciales son desconocidas.…”
