| Abstract | ||
| 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..... | ||
