Abstract:

 

The forkbeard, Phycis phycis (Linnaeus, 1766), is a species widely distributed throughout the Mediterranean and  Adriatic Sea and although it is of great importance for fishing industry, little is known about its reproductive characteristics.  This study provides first data on reproductive characteristics of this species in the Mediterranean, important for management  and stock assessment. For this purpose a total of 550 individuals ranging from 19.9 to 45.8 cm in total length were collected  monthly in a period of one year using trammel nets. Sex ratio of males to females was 0.62:1. The estimated length where  50% of analysed individuals were sexually mature was 30.98 cm for females and 32.98 cm males. The peak value of  gonadosomatic index was recorded in November and continued throughout the December, indicating the highest spawning  activity. This period is characterized by presence of oocytes with migrated nucleus and yolk coalesces in ovary and  spermatozoa in testes. 	 	 		 .
