Balık Sağlığı ve İmmunostimulanların Kullanımı

Abstract

Özet:Balık hastalıkları ve enfeksiyonları nedeniyle meydana gelen ekonomik kayıplar gibi problemler su ürünleri sektörünün gelişimi açısından büyük önem taşımaktadır. Günümüzde birçok balık hastalık etmeninin tedavisi için halen etkin bir çözüm geliştirilememiş olması ve var olan tedavi yöntemlerinin ise balıklar için ekstra bir stres kaynağı olması, bilim adamlarını balık hastalıklarına karşı immünostimulanların kullanımını araştırmaya sevk etmiştir. Bu derlemede balık hastalıklarına karşı kullanılan immunostimulanların avantaj ve dezavantajları ve mevcut immunostimulanlar üzerine yapılan çalışmalar özetlenmiştir. Abstract: Fish Health and the Use of ImmunostimulantsProblems such as economic losses due to fish diseases and infections, are the most important issue for the development of the fisheries sector. Current studies focus on the use of immunostimulants against fish diseases due to the fact that there is still no effective treatment for a few fish diaseases and the available treatments possess additional stres for fish. In this review, the advantages and disadvantages of the immunostimulants used against fish disases and studies on the current immunostimulants are summarized.

Some Hematological and Non-Specific Immune Responses of Rosehip (Rosa canina) - Fed Russian Sturgeon (Acipenser gueldenstaedtii Brandt & Ratzeburg, 1833) to Mycobacterium salmoniphilum

“…Rosehip is a fruit from the Rosacea family, used by the general public for its therapeutic properties for centuries. Its high vitamin C content is well-known and its seeds are used in fish and bird feeds 3,25 . Due to its high vitamin C content, when used as a feed additive, it promotes the healing of wounds and lesions, accelerates the healing process, and can be used for therapeutic purposes.…”

“…Antioxidant vitamin C found in the composition of rosehip is also an important immunostimulant forming bactericidal and viral resistance and activity against pathogens in fish, and stimulating the proliferation and phagocytosis of the immune cells (Ergönül et al, 2012). The study material, rosehip, is an important herbal immunostimulant used for the stimulation of carotene pigment erythropoiesis in foods, treatment of wounds and lesions, and also in skeletal deformities (Kılıçgün, 2008;Lim et al, 2000).…”

“…Due to the negative effects of these pharmacological substances or hormones on humans and the environment, the majority of the studies conducted in the last 20 to 25 years have focused on the use of immunostimulants that will strengthen the immune system, rather than the treatment of fish (Ergönül et al, 2012). In aquaculture, vitamin C (ascorbic acid-AA) which is one of the most commonly studied micronutrients of immunostimulants is an important antioxidant in many teleost species and has various functions in hematopoiesis and in the immune system (Lim et al, 2000).…”
