This paper examines the vulnerability context of migrant workers in the informal sector in three Indian cities (Kochi, Surat and Mumbai), specifically in terms of how their livelihoods interface with climate variability, related hazard events and social inequities. It examines the progression of population vulnerability from a political economy perspective. The underlying assumption is that migrant workers' vulnerability to climate variability in cities is closely embedded within the wider political economy of their day-today livelihood struggles. A mixed methodology design was adopted to carry out the study. Data from 50 migrants in each of the three cities were collected using a semi-structured interview schedule. The research demonstrates that urban vulnerability is a condition that shapes and reshapes itself continuously and fiercely, accompanied
Spawning and successful rearing of larvae of honeycomb grouper Epinephelus merra Bloch 1793 upto juvenile stage was accomplished at the ¢n¢sh hatchery of Mandapam Regional Centre of Central Marine Fisheries Research Institute during 2004. The fertilized eggs were free, spherical and buoyant with size ranging from 710 to 730 mm. Complete early embryonic development took place within 24^27 h and hatching occurred. The hatchlings measured1.5 mm. Mouth opening (115 mm) appeared at 72 h when the larvae were 2.2 mm in size. Pectoral ¢n developed on the ¢fth day. Complete metamorphosis took place and by the 60th day the larvae transformed into juveniles (45 mm) and attained skin colouration and honeycomb pattern.
