Biography & Research Interest

Welcome Dr N. R. Chattopadhaya to join the Editorial Board of American Journal of Marine Research and Reviews.

Prof. Nihar Ranjan Chattopadhaya, now attached to Dept. of Biotechnology, Govt. of India as visiting professor since 1st June 2017. Previous to it I was ex- Professor and Dean, Faculty of Fisheries sciences, West Bengal University of Animal and fisheries Sciences, Kolkata, West Bengal India, for a period of 22 years.

Research work
I. As U.G.C. junior fellow carried out work on the influence of organic manures on the behavior, survival and growth of fish and awarded Ph.D. During the fellowship period study was conducted both in earthen vats and cemented cistern for a period of three to six months to determine the minimum optimum dose of manures and lime at which maximum productivity and production can be achieved .Impact of soil-water parameter and benthic organisms were assessed at 10 day’s interval. Data were analyzed statistically to correlate the impact of different parameters on the growth and yield of fishes. At the end doses were recommended for individual as well as manure mixture and lime at which maximum productivity, growth and yield can be obtained.

II. As Reader (Research) in Fisheries, NARP:
As Reader (Research) in Fisheries joined NARP under State Agriculture University in 1994 and continued up to 1996. During the period, I have conducted a preliminary survey with a view to gain knowledge about the existing fisheries potential in the different agro-climatic zone of the state. After completion of the survey specific and zone–based program were formulated for the development of aquaculture. This included demonstration on
a) Feasibility of Pisciculture in a jute retting pond.
b) Advanced nursery, rearing and stocking management practices of carps.
c) Breeding techniques of carps and catfishes.
After completion of project a report was prepared and the same was submitted to ICAR.

III. As Reader and Professor in Aquaculture, West Bengal University of Animal and Fishery Sciences.
I joined as Reader in Aquaculture in West Bengal University of Animal and Fishery Sciences in 1994 and now serving as Professor in Aquaculture and conducted the following programme.
A survey was conducted covering the major fish seed producing districts of Bengal and a report was prepared on the “Current status of Induced breeding technology in Bengal and its impact on aquatic biodiversity”. The focus point of the study was to review the mode of application of the technology in farming condition. During the study, it was revealed that the farmers who shouldered the responsibility to produce about 70% seed, don’t have any secondary school leaving certificate and did not back up with any institutional and or Scientific training. The ignorant farmers, inadvertently, use the technology only for the profit making. Inbreeding, genetic introgression, genetic drift and gene contamination are the genetic consequences that are happening in the farming system. The reduced potency of gland and small number of founder population results in loss of heterozygosis and inbreeding depression. Along with this the farmers introduce and breed exotic species every year. Hybrids are produced out of the crosses of IMC with exotic species. The study reveals that all these activities in farming situation not only produce a negative impact on Aquatic biodiversity but put a threat on the native gene pool.
IV. Standardization of farm practice:
1) As Professor in Aquaculture, standardized the breeding and larval rearing of Pangasius sutchi. in captivity(Ref-Aquaculture Asia.Jan-March,2002,Vol.VII.No:1;p-43-44)
2) Captive Breeding and enhanced fertilization of common carp (Cyprinus carpio).
3) Feasibility of pisciculture in jute retting water body.(Report is attached)
4) Standardization of breeding and larval rearing of Pacu. (Communicated to Aqua. Asia.)
V. Conducted research on protection and conservation of aquatic biodiversity in both fresh and brackish water sector.
VI. Conducted research on present status of sewage fed fish farming in Kolkata with a view to protect and maintain sustainability of this age-old and world famous culture system of Kolkata, West Bengal.
