Sari, Mazandaran Prov., Oct 27 - While some lecturers describe implementation of the plan for farming rainbow trout in cage in the Caspian Sea unprincipled and catastrophic for the environment, executive officials believe the plan is beneficial in creating job opportunities.
Currently the plan for farming fish in cage in the coastal area of Kalarabad, west of Mazandaran Province, is being practiced by a private sector investor.
Although fish farming in cages installed in the sea is currently being practiced by some countries active in the field of aquaculture, however in the opinion of some experts its practice differs in different seas and lakes.
According to some faculty members of Mazandaran universities, the plan for farming rainbow trout in cage in the Caspian Sea is non-professional and ignores the environmental consequences.
They believe that different pollution will be caused by farming in this way, calling on the senior environmental and fishery officials to save the Caspian from implementation of the plan.
The Caspian Sea is the largest enclosed body of water on Earth by area, variously classed as the world's largest lake or a full-fledged sea. The sea has a surface area of 371,000 km2 and a volume of 78,200 km3. It is in an endorheic basin (it has no outflows) and is bounded to the north by Russia, to the south by Iran, western Azerbaijan, and eastern Kazakhstan and Turkmenistan.
Hossein Rahmani a lecturer at Agriculture and Natural Resources University of Sari told IRNA that since the Fisheries Department is in charge of implementation of the plan, its adverse results should be carefully assessed by experts in that office.
He further added that although the officials are after creating job opportunities and farming more fish, however through farming of this non-native species their aim will not be realized.
Meanwhile, an official at Mazandaran Fisheries Department said necessary permits have been obtained from the environment and veterinary organizations for fish farming in five points of the Caspian Sea.
Rejecting sensitive reactions shown over environmental consequences of entry of rainbow trout into the Caspian Sea, Seyed Sohrab Mir-Kamali said each cage produces at least 20 tons of trout.
