Abstract Fish health assessment is essential for maintaining sustainable aquatic ecosystems and ensuring the well‐being of wild farmed fish populations. Hematological parameters are crucial indicators health, with poikilocytosis emerging as a fundamental marker significant diagnostic value. Poikilocytosis refers to abnormally shaped erythrocytes in bloodstream, reflecting underlying physiological pathological conditions. can occur various species be influenced by environmental stressors,...
Transportation of fish, although stressful, is an inevitable procedure in aquaculture practices. In this study, we investigated the changes biochemical and haematological indices advanced fingerlings rohu, Labeo rohita order to optimize packing density as imperative avoid transportation stress associated mortality. The fish (14.00–15.00 cm) were packed sealed double layer oxygen polythene bags 30 L capacity containing 7.5 water transported for 2 h min a motor vehicle at three densities,...
Florfenicol (FFC), an approved aquaculture antibiotic, is administered in feed at doses of 10–15 mg kg biomass−1 day−1 for 10 successive days. In this study, healthy Oreochromis niloticus were fed with 0–10 times the therapeutic dose 15 days and tracked 43 post dosing. Assessments residue accrual depletion, oxidative stress, serum biochemistry, histopathology extent kidney liver damages made. FFC dosing reduced intake significantly. The produced no mortalities on day 10. Dose-dependent...
The present study was carried out to evaluate the effect of oxytetracycline (OTC)dosing at five different concentrations, viz., 0 mg (0X), 80 (1X), 240 (3X), 400 (5X) and 800 (10X) kg -1 biomass day for 30 consecutive days on growth, safety intestinal histology Nile tilapia, Oreochromis niloticus (L.) juveniles.The OTC-residues in edible muscle were detected scheduled intervals by LC-MS/MS.A dose-dependent decline feed intake, survival recorded OTC-dosed fish.The OTC-residue levels 0,...
Abstract Aeromonas hydrophila infection is one of the key factors limiting tilapia production, and antibiotics play important roles in control diseases. This study evaluated effectiveness florfenicol (FFC) when administered orally at therapeutic dose 15 mg/kg fish biomass/day for 10 days against A. Oreochromis niloticus terms survival, changes haemato‐biochemistry, erythrocyte morphology, histoarchitecture vital organs. was moderately virulent to with an LD 50 1.15 × 7 cells/fish. When...
Antiparasitic drugs are vital for eliminating infectious fish parasites in aquaculture. However, medications used to control can disrupt the physiological and biochemical processes of fish. This study explored safety margin administering emamectin benzoate (EB) at graded doses—0, 50, 125, 250, 375, 500 μg/kg biomass/day—for 14 days during onset winter perturbations enzymatic activities male Oreochromis niloticus fries compared control. Oral EB administration affected biological a dose-,...
The aquaculture industry urgently requires effective bacterial disease management strategies, necessitating better regulation of antibiotic application. This study investigated the effects oral oxolinic acid (OA) administration on Oreochromis niloticus at recommended dose 12 mg (1 ×) and overdose 36 (3 ×)/kg biomass/day for 7 consecutive days in terms growth, oxidative stress, residue accretion histopathology relative to control. 1 × 3 groups experienced dose-dependent mortalities (3.33-8.33...
Streptococcosis is considered one of the most important diseases affecting farmed tilapia, causing severe economic losses. Antimicrobial therapy principal control measure applied during outbreaks. This research assessed efficacy florfenicol (FFC) when fed at 15 mg kg biomass–1 day–1 for 10 days against Streptococcus agalactiae infection in Oreochromis niloticus terms survival, changes hemato-biochemistry, erythro-morphology, and histoarchitecture vital organs. was moderately virulent to O....
Economic burden of diseases on Indian aquaculture sector was estimated to be US$ 2.48 B, 14.95% annual production value. Analysis revealed a higher cost disease (US$ t −1 ) in shrimp (1,224.82) followed by marine fish (815.87), IMC+ (364.89), tilapia (260.34), IMC (200.70), and pangasius (pond 198.92; cage 168.36). The major contributors the included loss (23.90%), expenses prophylactics (50.31%) therapeutics (17.26%). economic dominated multiple etiology 468.27 M), bacterial hemorrhagic...
Aquaculture is an important source of cheap animal protein for human consumption. The intensive hatchery and aquaculture activities make the seed/fish vulnerable to diseases, which demand application drugs. present study evaluated impact in-feed oxytetracycline (OTC) administration ranging from therapeutic (80 mg) overdoses (240, 400 800 mg/kg biomass/day) 10 days on histopathology Oreochromis niloticus fry in comparison with control. kidney exhibited degeneration renal tubules tubular...
The experiment was conducted in 2015 (March–May, 2015) at aquatic animal health laboratory, Faculty of Fishery Sciences, Kolkata, West Bengal, India. Klebsiella pneumonia a rod-shaped, Gram-negative, and facultative anaerobic bacterium. It widespread nature found many environments such as soil, plants, industrial effluent, sewage, surface water drinking water. one the important human pathogens, causing most commonly pneumonia, typically bronchopneumonia bronchitis. However, there were few...
Abstract Bacterial diseases such as motile Aeromonas septicemia are major constraints on aquaculture. This study evaluated the efficacy of oral oxolinic acid (OA) therapy at 12 mg kg biomass −1 day for seven days to treat veronii -Av-F ( AV ) infection in Oreochromis niloticus . The lethal dose 50% mortality was determined be 1.81 ×10 8 cells fish Following intramuscular 2.47 × 10 , OA treatment significantly reduced and accelerated wound healing. caused notable changes biochemical,...
