Embryonic and larval development of (Gattan) Barbus xanthopterus (Heckel) from Tigris River system, Iraq Title???


Author(s): Hamad Haider Abbas, Bawazir Abdullah Salem and Ali Attaala M

Abstract: The study presents preliminary observations on the embryonic and larval development of Barbus xanthopterus within the joint laboratory and pond conditions of the middle reaches of the Tigris River in Iraq. Broodstocks were collected from Tigris-Tharthar canal in March and April months. The eggs were obtained through induction of spawning under 22–24 ºC, by using spawning protocols of carp hormones. Perivitelline space formed 35 minutes after fertilization reaching maximum 1.8 mm in diameter at about 70 minutes. The first cleavage occurs in 1 hour 10 minutes, blastula was observed in 7 hours. The formation of first somites was observed 18-20 hours after fertilization. The first hatching occurred 55 hours after fertilization and lasts up to 105 hours. The true larvae develop into the juvenile period within about 60 days after hatching. Here we do not adhere to certain numerous developmental schemes but describing the general course of early development of Barbus xanthopterus.
