A survey team led by Mr.Abbasi from National Inland Aquaculture Institute is in progress to grasp the fish fauna of the Anzali Wetland and its distributaries as a Joint Pilot Activity, “Comprehensive Ecosystem Survey of the Anzali Wetland”. The survey started in March 2016.
Mr.Watanabe from JICA Expert Team joined the fish survey at Pasikhan River and Pishroudbar River which flow into the Anzali Wetland on 5th Dec, 2016.
Mr.Abbasi and his team recorded more than 10 fish species such as Bitterling (Rhodeus sericeus amarus), Caspian Kutum (Rutilus frisii kutum), Keyvan’s Spined Loach (Cobitis keyvni), and Iranian Goby (Ponticola iranicus) in a day. Prussian carp (Carassius auratus gibelio) was also recorded as alien species. These scientific data are very important to conserve the wetland ecosystem.
On the other hand, the team found that dams in river block migratory fish such as Caspian Kutum to go upstream to spawn. Fish way is one of solutions to enable fish to go upstream. One dam under the three sisters’ bridge in Pishroudbar River has fish way. However it doesn’t seem very good for fish migration. Fish way should be installed to the other dams to conserve the reproduction of anadromous fish. There are many good practices of fish way in Japan. JET can help to plan of fish way for the Anzali Wetland ecological network conservation.
