Effects of oxytetracycline residues in Thai Koi (Anabas testudineus Bloch) collected from Sylhet, Bangladesh

Bangladesh is uniquely rich in productive water resources and blessed with diversified fisheries resources (Kibria and Ahmed, 2005) which are composed of 260 freshwater native species, 12 species of exotic fishes, 24 species of freshwater prawn, 475 marine fish species and 36 species of marine shrimp (Haque, 2005). In Bangladesh, about 63% animal protein of our meal comes from fisheries resources (Ahmed, 2005). That’s why fish and fisheries are the essential part of Bangladeshi people from the time immemorial and play a dynamic role in the meeting up nutritional demand, generating employment, earning foreign currency and other aspects of the economy (Alam, 2002). On the other hand due to favorable climatic condition the water bodies are highly productive and aquaculture is an important commercially viable activity and also plays a major role in country’s total production from fisheries sector (DoF, 2003). Thai koi (Anabas testudineus) is one of the common exotic fish species in Bangladesh. It is considered as an economic and important fish because of its high market demand, potentialities for intensive culture of species, having shorter life cycle, faster growth rate and high nutritious food value and delicious taste (Kohinoor et al., 2010). Different infectious and non-infectious diseases constitute major constraints to aquaculture production (Bagumire et al., 2010). In Bangladesh, disease outbreaks have been recognized ORIGINAL RESEARCH ARTICLE Archives of Agriculture and Environmental Science 3(2): 174-179 (2018) https://doi.org/10.26832/24566632.2018.0302011
