mullets of a reservoir fishery in Okhamandal
(Gulf of Kutch) with special reference
to rural development along the coast

Subject Mullet
 
Description Grey mullets formed S7% of the annual marine fish production during 1984-87 from the
reservoirs of a solar saltworks along the Okhamandal coast of the Gulf of Kutch. Mugil cephalus
(23.0%), Mugil macrolepis (35.03%), Mugil parsia (1.29?-^), Mugil tade (0.629%) and Mugil
car/natus (40.06%) formed the composition of the catch- Maturing specimens of Mugil cephalus.
Mugil macrolepis and Mugil parsia were observed in the catch.
In view of the excellent prospects of aquaculture of this highly esteemed group of fishes, and
considering the limited seed resources of 1,64 million per annum from the natural sources, a study of
the gonadial development and spawning of the commercially important species was undertaken. Based
on the data, experiments to indues the development and spawning were also conducted. Conditioning
and prevention of diseases from infection due to injury wore major problems. Both Mugil macrolepis
and Mugil parsia responded to pituitary hormone Injections, developed ovaries and spawned in 7 days
and 37 days respectively.
The prospects of rural development through mullet culture in the coastal areas of Kutch are
discussed.
