Small indigenous cyprinids as bioindicators of freshwater ecosystem health: a comprehensive monitoring assessment from the Gumti River, Northeast India.

Small indigenous fish species serve as valuable bioindicators for freshwater ecosystem health assessment, yet comprehensive baseline data for tropical cyprinid species remain limited in Northeast India. This study establishes baseline reference data and evaluates the bioindicator potential of three sympatric cyprinid species through integrated morphometric, physiological, and reproductive assessments. Amblypharyngodon mola Hamilton, 1822; Esomus danricus Hamilton, 1822; and Puntius sophore Hamilton, 1822, were systematically monitored across three sites in the Gumti River, Tripura, Northeast India, over 12 months.

Comparative analysis of carbon sequestration potential in different wetland ecosystems: insights from phumdi-dominated wetlands of Northeast India.

Wetland ecosystems are vital for global carbon sequestration, yet floating biomass formations (phumdi) remain understudied despite their unique ecological characteristics. This research presents the first comprehensive comparative analysis of carbon sequestration across three wetland types in Manipur, Northeast India: Pumlen Pat (open wetland, 8697.13 ha), Lamphel Pat (closed urban wetland, 587.

Effect of Saprolegnia parasitica infection on immuno-biochemical parameters and disease resistance capacity of Labeo rohita fingerlings.

The oomycete water mold Saprolegnia parasitica poses a considerable threat to the global aquaculture industry, leading to substantial economic losses. This study aimed to investigate the effects of experimental S. parasitica challenge on key immunological, biochemical, and hematological parameters, as well as disease resistance, in fingerlings of Labeo rohita, an important freshwater carp species farmed across Southeast Asia.

Environmental impact assessment of stocking density in bamboo cage aquaculture: examining water quality dynamics, stress biomarkers, and ecosystem response in a subtropical forest water body of Northeast India.

Forest-dependent communities in India, particularly in the Northeast region, face significant socio-economic challenges while possessing vast untapped aquatic resources. This study investigated the environmental sustainability of varying stocking densities (5-20 fish/m3) of Indian major carp Catla catla in eco-friendly bamboo cages within a forest water body in Tripura, Northeast India, intending to develop low-cost aquaculture solutions for forest dwellers. Water quality parameters, stress biomarkers, and ecosystem responses were monitored over 6 months.

Evaluating the dietary effects of curry and/or marigold leaf extracts on physiological and immunological responses of Labeo rohita and its resistance against Saprolegnia parasitica infection.

This study examined how combining curry leaf (Murraya koenigii) and marigold leaf (Tagetes erecta) extracts affects immune response and disease resistance in Labeo rohita (rohu) fish against Saprolegnia parasitica infection. We conducted a 74-day trial using 360 juvenile rohu divided into four treatment groups: control (T0), curry leaf extract (T1), marigold leaf extract (T2), and combined extracts (T3). The trial consisted of a 60-day feeding period followed by a 14-day pathogen challenge test.

Harnessing the immunomodulatory potential of ashwagandha (Withania somnifera) against epizootic ulcerative syndrome: a sustainable approach for hill aquaculture.

The present study evaluated the immunomodulatory and disease resistance-enhancing effects of dietary supplementation of Withania somnifera root powder in Labeo rohita (22.10 ± 3.30 g, 12.

Alteration in cerebral blood flow, kynurenines with respect to mood profile in freshly recruited armed forces personnel.

The present study is conducted to understand the association of mood profile with the kynurenine pathway (KP) metabolites, and cerebral hemodynamics in freshly recruited central armed forces personnel. Profile of Mood States questionnaire was utilized to assess mood profile, and Total Mood Disturbance (TMD) score was calculated. Transcranial Doppler was used to record blood flow velocity bilaterally of the middle cerebral artery.

Effect of feeding Lipopolysaccharide as an immunostimulant on immune response and immune gene expression of Labeo bata.

This study investigates the effects of dietary lipopolysaccharide (LPS) as an immunostimulant on hematology, innate immunity, immune gene expression and protection against Edwardsiella tarda on Labeo bata. A basal diet supplemented with 0, 50, 100 and 150mg LPS kgdiet was fed to the four different groups for 30days. The haematological (total erythrocyte count, total leukocyte count, total serum protein, albumin and globulin), innate immune parameters (respiratory burst, serum lysozyme, myeloperoxidase and serum bactericidal activity), immune gene expression (C3, β-2 microglobulin, lysozyme g, transferrin, IFN-1, IFN-γ) were monitored at 7th, 15th, 30th day and one day post challenge (DPC) with E.

Innate immune response of Indian major carp, Labeo rohita infected with oomycete pathogen Aphanomyces invadans.

The fish pathogenic oomycete Aphanomyces invadans is the causative agent of epizootic ulcerative syndrome (EUS), a fish disease of international significance and reportable to the World Organisation for Animal Health. In spite of the current and potential impact of A. invadans infection on fisheries and aquaculture sectors of the world, very little is known about the host-A.

Effect of β-glucan on the immune response of early stage of Anabas testudineus (Bloch) challenged with fungus Saprolegnia parasitica.

The present study was carried out to study the effect of different dosages of β-glucan suspension on immune response and disease resistance in Anabas testudineus spawns against a fungal pathogen Saprolegnia parasitica. Eight day old spawns were exposed for 3 h in four different dosages of β-glucan suspension in phosphate buffered saline at the rate of 0, 5, 10, 15 mg l(-1). The cell suspension of spawn was assayed for total protein, acid phosphate, lysozyme, bactericidal and NBT activity.

Effect of beta-glucan on immunity and survival of early stage of Anabas testudineus (Bloch).

The present experiment was carried out to study the effect of different dosages of beta-glucan suspension derived from barley on the innate immune response and disease resistance of Anabas testudineus spawns against infection caused by Aeromonas hydrophila. Four different dosages of beta-glucan suspension in phosphate buffered saline at the rate of 0, 5, 10, 15 mg l(-1) were taken and 8 days old spawn were exposed for 2 h and 3 h. The cell suspension of spawn was assayed for total protein, acid phosphatase activity, lysozyme activity, bactericidal and NBT.
