In line with the new fisheries extension system and the production assistants plan, the Memorandum of Understanding for joint research and fisheries extension collaborations was signed between the National Inland Water Aquaculture Institute and Mr. Abbas Naemi, the manager of the Gamma Fish Farm. At the first phase of the Memorandum of Understanding, research and extension activities on selectively bred Tata carp will be completed with the aim of introducing a new and well - growing species to the aquaculture industry in the country. It should be mentioned that the Gamma Fish Farm is one of the famous farms with a brilliant history in the Gilan province. This farm has been cooperating with the researchers of the research institute since last year in the field of the fisheries extension plan to introduce Tata carp to warmwater fish farms in the Gilan province.
