Activities/focus

  • Survey of fish hatcheries of West Bengal and Assam
  • State wise comparison of impact of monsoon period on breeding period
  • Monthly variation of gonadal maturity stages of Indian major carps and its relation to climate variables in West Bengal, Assam, Tripura, Odisha, Madhya Pradesh, Andhra Pradesh, Uttar Pradesh and Uttarakhand
  • Relationship between spawning characteristics and climatic variables
  • Seasonal pattern of GSI of Tenualosa ilisha at Hooghly-Matlah estuary system
  • Extensive fish sampling of Indian major carps, mahseer, snow-trout, and rainbow trout brooder in different parts of Uttarakhand and Himachal Pradesh to assess the status of fish breeding and impacts of climate changes on different breeding aspects
  • Estimation of biochemical parameters in serum at different ovarian maturity stages of Cirrhinus mrigala
  • Survey in the hatcheries of Assam for fish species diversification for breeding programme
  • Adaptive strategy undertaken by farmers to cope with the extreme weather conditions of drought in majority of the hatcheries
  • Changes in the hydrological system relevant to fish and fisheries over Cauvery River basin
  • Studies on the rainfall and temperature pattern in river basins
  • Documentation of different adaptive measure viz. deep pools, net pen enclosures, temporary pre-summer enclosure
  • Soil and water sample colllection from different wetlands of West Bengal (Akaipur, Khalsi (floodplain wetlands) and East Kolkata (Jhagrasisa, sewege fed wetland)) to generate pilot-scale information on wetland carbon pool and C sinking capacity
  • Assessment of fish assemblage pattern in relation to climatic variation in middle stretch of River Ganga
  • Assessment of spawning behavior of 8 target fishes in relation to climatic variations in selected stretches of River Ganga and in floodplain wetlands of West Bengal and Assam
  • Beneficial impact on reproductive traits of fishes in relation to Climate Change and habitat
  • Region specific climate dependence models for predicting certain reproductive biology parameters of 9 target fishes (Channa punctatus, Eutropiichthys vacha, Johnius coitor, Mystus tengara, Mystus cavasius, Odontoamblyopus rubicundus, Puntius sophore, Amblypharyngodon mola and Colisa fasciata) from Ganga River basin under various temperature and precipitation regime
