Microprotein The microprotein levels at 90 days (MPR90) significantly increased in T2 (< 0.05), with no significant difference observed between CT, T1, and T3 (> 0.05). with other species and consumer preferences, the fish plays an important role in six species composite aquaculture in South-East Asian countries including India [3]. Current fish production is insufficient to meet the rising demand, with global Rabbit Polyclonal to AK5 per capita fish consumption hovering around 20.3 kg [2]. The strategies for increasing fish production as a prime demand include deploying new culture technologies in reservoirs and wetlands alongside existing culture practices, which are dependent on several factors such as scientific CI 972 farming, quality feed, seed, and effective disease management measures [4]. Klesius et al. [5] reported that 10C15% of the total value of fish production worldwide is lost due to different diseases. In India, for example, Andhra Pradesh shares a major chunk of 40,000 tons of major carps, worth INR 600 million per year, but the loss due to disease outbreak is estimated to be INR CI 972 40 million. The conventional approach to disease treatment is antibiotics, and the irrational use of chemicals and substances for growth promoters and immunity boosters has raised concerns about the expansion of disease-resilient strains of bacteria and the presence of noxious chemicals in fish flesh. The authors of [6] stated that herbal products including ethno-medicinal plants have emerged as a potential alternative to obnoxious chemicals and antibiotics used in aquaculture. Herbs can act as immunostimulants, activating innate defense machineries in fish and increasing the adaptive immune system. The authors of [7] reported that numerous studies have shown that herbal additives promote fish growth and protect against disease. for its antioxidant potential, while [9] investigated its antimicrobial activities. Meena et al. [10] concluded that can be considered one of the beneficial plants to fish nutrition and health. Meena et al. [10] revealed that dietary TABP showed results in accordance with its serum biochemistry and other parameters. Secondary metabolites known as bioactive compounds mediate the health benefits. The authors of [11] studied the effects of the leaf extract of on water quality, blood profile, and survival of Betta species. The study revealed that immersing leaf extract beyond 375 ppm is advantageous in enhancing survival, WBC, RBC, and CI 972 Hg of Betta species. The authors of [12] discovered that has antioxidant, hypotensive, antiatherogenic, anti-inflammatory, anticarcinogenic, antimutagenic, and gastroprotective properties in humans. A comparative study and CI 972 detailed information for evaluating the health beneficial properties of this plant extracts on fish are deficient. As a result, the current study was designed to generate detailed information about the dietary effects of bark-powder-based fish feed on hematological, immunoglobulin level, and humoral responses in were purchased from the local fish market (average weight, 20.3 0.34 g) and reared in a 5000 L cement cistern for two weeks acclimatization at ICAR-CIFRI, Barrackpore, Kolkata, India. A 90 day study was designed and performed in triplicate, using a completely randomized design (CRD). In triplicate, 540 fish (average weight: 20.7 0.34 g) were assigned to four different dietary treatments. Fish were reared in a flow-through system in a 500 L tank and were fed twice daily (9.30 am and 5.00 pm) up to satiation. Sampling was carried out every month to check the growth and health status of the fish. 2.3. Isolation of Pathogenic Bacterial Strains and Challenge Study Fish specimens exhibiting CI 972 clinical signs of disease were collected from an aquaculture farm in East Medinapur, West Bengal, India (Latitude 22.107897, Longitude 87.907583). Passive data collection revealed a reported 40% mortality within the total fish population. Individuals displaying clinical signs, such as body surface redness and hemorrhages, were selected and transported in aerated 50 L FRP tanks to the Fish Pathology Lab (ICAR-Central Inland Fisheries Research Institute), Kolkata, for etiological agent screening. Clinical and post-mortem examinations were conducted following established protocols. The animal utilization protocol for the.
