First record of a Leucosid crab<em> Paranursia abbreviata</em> Bell, 1855 from Devi estuary, Odisha Coast, India

117-119A leucosid crab Paranursia abbreviata Bell, 1855 is recorded for the first time from Odisha albeit from coastal waters of the Indian peninsula after half a century. Present study is an effort towards documentation of the species from Odisha, indicative of a range extension between the Coromandal coast and Gulf of Martaban, Myanmar

First and New Record of <em>Ceratium vulture v. sumatranum</em> and <em>Pediastrum species</em> from coastal waters of Paradip, Bay of Bengal, East Coast of India

1169-1171Plankton diversity studies were carried out in the coastal waters of Paradip, Bay of Bengal from January 2015 to October 2015. There was broad variation in plankton diversity and water quality indices. Higher number of plankton taxa was reported in the month of October when SST, DO and nutrient (NO3 and SiO3) concentration was also higher.  In the month of October the SST value was 30.80°C  and dissolved oxygen varied from 3.28mg/l to 5.21mg/l. Nitrate and silicate both show maximum in October month i.e., 76.89µM/l and 36.67µg/l respectively. Salinity was maximum in the month of March (37.21ppt) and minimum in the month of October (23.95ppt). Phosphate was maximum in January month (0.113mg/l) and minimum in March (0.08mg/l). Nutrients (nitrate and silicate), SST, DO and Salinity act as limiting factor in the distribution pattern of planktons
