Fisheries Research Station

Sikka (Dist : Jamnagar)

Year of Establishment : 1992 
Introduction:
Gujarat state is bestowed with a longest coastline of 1600 Kms amongst all the maritime states of India. The coastline possesses two gulfs viz., Gulf of Kutch and Gulf of Cambay. The continental shelf area is 1.64 lakh sq. km. and Exclusive Economic Zone covers 2.02 lakh sq. km. The state has 3.76 lakh hector of coastal area, providing immense potential for coastal aquaculture as well as mariculture. The coastal and littoral biodiversity is very rich and this is evidenced by marine catch of the state. The state ranks first in India as far as marine capture fish production is concerned.
The research centre was established in order to utilize Molluscan resources on sustainable base. But as coastal ecosystems got deteriorated duet establishment of industries on the southern periphery of Gulf of Kutch, habitat destruction due to bottom trawling, sand lifting from islands situated in the Gulf and other manmade activities including large fishing fleet, industry-mate fishing resulting into overexploitation of important Molluscan fishery. Department of fisheries , Gov. of Gujarat has established Fisheries Research Station at Sikka to carry out resource survey of economically important mollusks, its habitat and to develop technology for species preservation, production and propagation. The establishment of the present station is also based on the study of a marine zoologist Dr. James Hornel (1905-1917), who studied the marine zoology of Okhamandal in particular and suggested to develop technology for pearl production, preservation and rational exploitation of marine resources for uplifting the living standards of the fishermen and coastal communities.
The research centre was transferred to Gujarat Agricultural University in the year 1992 and finally merged into J.A.U. w.e.f. May, 2004. Since then this research station is engaged with the Mandate, standardization of technology in pearl production; resource survey of Edible oysters, Pearl oysters and Mussels. And finally to preserve the species of economic importance through hatchery spat production, rearing them and recruit them into natural Pearl oyster habitat. The centre is located 28 km west of Jamnagar and is connected with road.
Mandate :
  • Breeding and Culture of Pearl oyster. Breeding and Culture of Edible oyster.
  • Collection and Identification of different Mollusks in the area.
  • To find out possibilities of Breeding and Culture of other important Bivalves.
Objectives : 
  • To Breed and Culture Pearl oyster in controlled and hygienic condition. To Collect different Mollusks in the area and identify them.
  • To identify marine Plankton of the area.
  • To culture and maintain nanoplankton and Chaetoceros culture.
  • To standardize optimum salinity for the growth of Chaetoceros calcitrans.

o  None Plan: “મત્સ્ય સંશોધન યોજના અને વિકાસ”
  • Breeding and culture of Pearl Oyster (Picnctada fucata)
  • Comparison of EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) content of four marine micro algal species
  • Aspects of the biology and fishery of Scylla serrata (forskal) and Portunus pelagicus in and around Sikka
  • Live feed culture of nanoplankton Isocrysis galbana and Chaetoceoros
  • Study of survival and growth of Pearl oyster in captive cage in Gulf of Kachchh at Sikka and Okha
  • Breeding and culture of Saccostrea cucullata
Research Activities :
To breed pearl and edible oysters in laboratory in controlled condition. To rear them by giving proper feed nanoplankton and then Chaetoceros. When juveniles can resist and survive in natural environment, they are released in sea. So that total population of these oysters can be increased. Depletion in natural stock has been observed since 1980. During 2009-10 a total of 195 lakh pearl oyster D stage produced of which 1 lakh were reared up to spat stage and rest of them were sea ranched for natural stock enhancement in different islands like Pirotan, Manjar, Goose, Datya, Chakhri, Sichaya and intertidal area of Sikka region. Collected different mollusks from the area and identified more than 168 mollusks which are preserved in laboratory for ready reference.
Achievements :
  • The centre has standardized Pearl production technique in Pearl oyster Pinctada fucata and has produced more than 3000 good quality pearls.
  • The centre has succeeded in production of Pearl oyster spat for the first time in Gujarat (2002-03).
  • The centre has succeeded in the production of mass scale spats of Pearl oyster, very recently (2009-14)
  • The centre got first success in acclimatization and induced spawning in green mussel, Asian Green Mussel (Perna viridis) for the first time.
  • The time taken for Pearl production is comparatively lower than that of south Indian Pearl Oysters.
  • Survey of Pearl oyster beds (Locally known as “Kaddahs”) and estimated pearl oyster population in islands.
  • Succeeded in production of pure culture of nanoplankton such as Isochrysis galbana and Chaetoceros calcitrans and has sustained/maintained these planktons in indoor culture on long term basis.
  • Under the pearl culture project this station has a successfully produced first and free spherical cultured pearl in December, 1980.
  • Station has identified and documented 24 no of species of opisthobrach and among them 20 breed successfully during 2015-16.
