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 unex.....

The survey was conducted in the western part of Hormozgan province in the spring of the year 1370 (1991) and covered nine important landing centres in the area From east to west these centres are as follows: Bandar - e - Kang, Bandar - e - Lengeh, Bostaneh, Maghvieh, Hosseinieh, Garzeh,.Moghom, Lavan Island and Gavbandi.. Acquired results show that on average 306 vessels including122. boats, 153 launches and 31 sardine fishing boats named Ammeleh, has been active every month, During the investigation period, 2280 tones of various aquatics catched of which sharks (CARCHARHINIDAE sharing %16 (365 tonnes) of the Tidal catch ranked in the first grade. Also among The investigated center, Bandar - e - Kang with 84 launches and a total catch of 1409 tonnes was the most active. The most important gear used in fishing was gilinet, sharing %78 of the total catch......

Studies show that there are some freshwater fishes which can survive in brackish and saline waters. Although it is not long that study on the tolerance of fishes against various salinities and effect of salinity on growth rate has been caught up in sclentific fields and that only a few fishes have been subjected to such studies, promising results encouraged us to carry out similar experiments on Barbus sharpeyi from cyprinidae Freshwater Barbus sharpeyi transferred to brackish water with different salinity degrees in three stages as follows : 1) Direct transfer from freshwater to waters of 2, 4, 6, ... , 16, 18 ppt salinity 2 Stepwise transfer to waters of 1, 2 3,...., 17, 18 PPt salinity for tolerance studies. 3) Stepwise transfer to waters with two degrees difference in salinity, for growth rate studies. in this phase freshwater was taken as control. Statistical analysis Computer analysis of acquired data was carried out using t.student and ANOVA statistic, Analyses were signifi.....

Species of cephalopoda and biological characteristics of Sepia pharaonis, were investigated in tho fishing grounds of Goitre" to "Gallak" corresponding to 61,31 - 59,30 eastern longitude and 25,10 - 25,23 northern latitude respectively. The balk of the study was confined to chabahar estuary during which 8 cephalopoda species were identified With Sepia pharaonis beingihe dominant one. Spawning of S. pharapnis occurs between the two southwest and northeast monsoon periods in December and November. Although spring spawning is demonstrated to occur, it is Are spawning which coniribute mostly io regeneration of S. pharapnis. Water temperature in spawning season varies between 22 to 28.5 degrees centigrade. Fishing season in this arca overlaps with spawning or S. pharaonis and in this period they have been found to migrate from deeper waters to shallower waters in littoral zone. The best fishing grounds in Systan - o - Baluchistan provirice are recognized to be "Ties and "Pozm". A s.....
