On Kika fishing Status in the Caspian Sen
1993
Razavi, B.
lran's commercial catch on this fish commenced in 1971 and inspite of recent years endeavour to boost the development of kilka fishery , the catch didnot exceed 15 thousand tonnes by year 1991, In this regard a one year survey program conducted in 1991 data collected and stock status identified in Iranian coasline at areas with a seabed depth of 40 to 80 m, in 56 fishing stations spaced at 10 mile intervals along ihe coast. The survey showed that Clupeonella engruliformis is dominant (91,8 %) followed by Clupeonella grimi (6,84%), and Clupeonella cultriventris which shared only 135 % of the total catch, FLA Furthemore 69.95% of Anchovy type kilka, 81.06 6%. of Big eye kilka and 80.88% of common kilka beionged to 2+ and 3+ year class. This major fishing study which carried out in Bandar Anzali using"Catch per Unit Effort" Method, reflects practical variability in fishing and shows that there 1q re more suitabk areas with higher densities than Bandar Anzati stations which are yet unexploited. 17 fishing stations from among 56 demonstrate catch rate ranging from 800 - 1200 kg kilka per unit effort per hour which can h ranked in the firsi class of kilka yielding grounds, Traditional fishing grounds in Anzali show the catch rate of 400 - 800 kg per unit effort per hour which is the second class in kilka fishing grounds category. The Iranian coastline bottom topography features sharp slopes which is a favourable habitat for wintering of kilka, The present study shows that possible yearly catch can be promoted up to a cieling of 100,1000 metric tonnes,
