Role of Kaolin on Hemtological, Biochemical and Survival Rate of Cyprinus Carpio Challenged With Pesuydomonas Aeruginosa

Abstract

In present study, we assessed the role of kaolin [(Al2Si2O5(OH)4), an inert clay], for treatment of common carp, Cyprinus carpio experimentally infected with Pesudomonas aeruginosa. Fish were experimentally challenged with P. aeruginosa (LD50= 2±0.2×109 CFU/ml), in untreated water or water treated with addition of kaolin at levels of 4, 6 and 8g/l (G1, G2 and G3 respectively). Over the 5‐day course of kaolin treatment led to significantly (P ≤ 0.05) improved of survival (100%) in treated groups (G2 and G3) as compared to untreated fish (infected group; 75% survival). Considerable changes were observed in blood parameters, leucocyte count recorded significant increase (P≤0.05) in G2 and G3 relative to C- and C+ groups. Erythrocyte count, Hb content and HT(%) reported significant decrease (P≤0.05) in all treated groups (G1, G2 and G3) related to C- group. Globulin level registered significantly increased (P≤0.05) in G2 and G3 than C+ group. The current study strongly recommends that treatment of common carp infected with kaolin at 6 and 8g/l improves survival, hematological and biochemical profile, against P. aeruginosa. Future complete molecular studies are required before application of kaolin as a treatment in aquaculture.

Efficacy of Silver Zeolite on Hematology and Survival Rate in Cyprinus Carpio Infected With Saprolegnia Spp.

“…In order to get pure colonies from the environment, 15-20ml of stream water was placed into a sterile petri plate with chloramphenicol. At that time, 5-7 sesame seeds, Sesamum indicum were placed in each petri dish (3). The plates were kept at 20 °C for 7 days, and every 24 hours, hyphae were looked.…”

Effect of Kaolin on Hematological and Biochemical Parameters of Cyprinus Carpio L. Against Copper Sulfate Toxicity

“…Aquaculture is described as the production of aquatic organisms, including fish, invertebrates, mollusks, and aquatic plants (5).Common carp is the most widely cultivated fish in the world, it has a high growth rate, continental habits, high fertility, flexible nature, ease of adaptation to artificial feeds, resistance to diseases and harsh environmental conditions (4,5,23). Fish health is an indicator of the pollution of the aquatic environment (6,7,26). Industrialization is a major catalyst for growth and urbanization, which release of various toxic chemicals, gases, solid wastes, and microbes of various types into our immediate environment-land, air, and water, water pollution is of particular interest because it has become a global issue (21,28).Heavy metals are important components of the aquatic environment, usually found in extremely low concentrations , heavy metals levels are too high in the area where domestic activities, mining activities, mechanical and electrical activities, cultivating activities are spread throughout the natural areas(31).…”
