Biological survey on cuttlefishes of Systan-o-Baluchistan waters (southeastern Iran)
Species of cephalopoda and biological characteristics of Sepia pharaonis, were investigated in the 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 being the 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 Autumn spawning which contribute mostly to regeneration of S. pharapnis. Water temperature in spawning season varies between 22 to 28.5 degrees centigrade. Fishing season in this area 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 province are recognized to be "Ties” and "Pozm". A series of analyses carried out on the meat, ink and cuttlebone of S. pharaonis and the ratio of ingredients were determined.
