Hello friend,

the role of fishery scientist has dramatically changed over the years. The fishery discipline has technically evolved. In the beginning the fish science was mainly dealing with classification, morphological studies of fishes, and the distribution of fishes in fresh water, marine water and in river stream.



The fishery scientist initially studied the external structure, on which classification was based. Later stages the role of fishery scientist changed and people started working on developmental aspects and molecular levels. During middle period the fishery scientist worked on breeding aspects of fishes. The scientists worked on fish breeding to fulfill the food requirements and for export purpose also.







Now a days the fishery scientists are working on :

Fish nutrition; here they are trying to find out cheap and easily available sources of nutrition for fishes. In some research projects, cow dung slurry from bio-gas plants are used as fish nutrition. It has been found that this supplemented even for micro nutrients required by fishes.



Fish breeding; the fish breeding science is in advance stage. The fishery scientist now breeding quality fishes (which has huge demand in market) using modern molecular biology techniques. This resulted in quality fish culturing with sufficient amount of nutrients. Scientist have also devised new and easy methods for fish culturing, so that small and marginal farmers can also apply to culture fishes in village ponds.



Fish microbiology and pathology: There are many microbes specially bacteria, which causes several diseases to fishes, which results in low production. Fishery scientists have developed new methods to improve the disease fighting ability in fishes. There has been tremendous growth in fish immunology field. Using immunological techniques and advance breeding practices, scientists are developing new and pathogen resistant fish species.



Fish genetics: the study of fish genetics leads to development of breeder quality fishes, which gain more weight and also nutritionally rich.



The fish research institutes such as; Central Institute of fishery technology, Central marine fishery research institute, Central inland fisheries research institute, Central institute of fisheries education, Central Institute of Fresh water Aquaculture and many universities are working towards the higher and better quality fish production.
