Students Successfully Spawn and Hatch Koi Carp

04/03/2017

Under the instruction and supervision of Dr. Wenresti Gallardo, students taking the Fish Reproductive Physiology and Breeding course at the Department of Marine Science and Fisheries, Sultan Qaboos University, were successful in inducing the koi carp to spawn last 16 March 2017 and two days after spawning, most of the eggs hatched. This is the first report on the successful breeding of koi carp in SQU and perhaps in Oman.

Koi carp is a large ornamental variety of common carp, originally bred in Japan but is now bred in other countries. Three years ago, koi carp juveniles were obtained from Thailand through the efforts of Dr. Gilha Yoon, MSF Technicians Mr. Ahmed Al-Souti and Mr. Adil Al-Sulaimani. The koi carps were reared in the aquaculture facility at the Agriculture Experiment Station (AES) of the university and are now ready to be used as spawners.

The baby fish (larvae) are now being taken care of by the students, namely Mohamed Al Wahaibi, Dhabya Al Rasbi, Madrak Al Aufi, Salim Al Mamari, Aaisha Al Rahbi, Bushra Al Kharusi, and Mohammed Al Qarni, with the help of Mr. Muntaser (AES staff) and Mr. Ahmed Al-Souti who serves as the Technician and Teaching Assistant for the course.

“Hopefully, we can continue to make the koi carps reproduce and we do not have to buy them from other countries. Adult koi carp with beautiful color design can be sold to fish hobbyists at around 50 rials per piece”, Dr. Gallardo said.

As a contribution of Sultan Qaboos University to the aquaculture development in the Sultanate of Oman, the Department of Marine Science and Fisheries at the College of Agricultural and Marine Sciences has enhanced its curriculum by offering new aquaculture courses such as Fish Reproductive Physiology and Breeding, Fish Nutrition and Feeding, Aquaculture Systems and Engineering, and Aquaculture Development and Management of its Environmental Impacts. Through these courses, students learn the theory and practice of aquaculture and prepare them to contribute to the aquaculture development of the country.
