This study aimed to develop a suitable protocol for the semen cryopreservation of commercially important minor carp Labeo gonius, aid in seed production and ex-situ conservation efforts. Semen characteristics were analysed, revealing pH ranging between 7.4-7.7, an average osmolality 276±15 mOsmol kg-1 sperm counts from 25.4×109 34.2×109 cells ml-1. Nine extenders screened three (8, 9B 9C) selected based on their high activation (over 70% with water as activator) motility time (>40 s)...

In subtropical regions, April to June represents a temporary moisture stress for mango trees, leading huge economic loss. Although water is available in the deep root zone, upper soil surface, which has fibrous roots, dry, and tree transpiration rate high. Moisture causes an increased oxidation state, detrimental fruit growth development. Finding substitutes management important sustainable production. To manage this mango, we tested if foliar application of 20, 50, 100 150 μM melatonin...

The hilsa shad <em>Tenualosa ilisha</em> (Hamilton, 1822), is a commercially important and highly relished food fish. This paper presents the length-weight relationships (LWR) condition factor of hilsa, throughout its geographical distribution in India. A total 910 samples <em>T. ilisha</em>, comprising 404 males 288 females collected from various locations east west coasts India were used for analyses. Heterogeneity LWR males, pooled population was noticed....

The reverse transcription quantitative real-time PCR (RT-qPCR) is widely preferred tool for expression analysis of target gene at mRNA level. However, in order to obtain significant biological comparison, data normalization a stable endogenous internal control also called reference (RG) utmost importance. In the present study, we evaluated stability four commonly used housekeeping genes, that beta actin, β-actin; glyceraldehyde-3-phosphate dehydrogenase, GAPDH; elongation factor-1 alpha,...

Chitala chitala (Hamilton, 1822) is an economically important food fish species occurring throughout Indian rivers, which also has ornamental value. This study focuses on morphological variations in C. from seven river basins across India namely; Son, Tons, Ken, Brahmaputra, Ganga, Gomti and Gandak. A truss network was constructed by interconnecting nine landmarks to generate 36 morphometric variables extracted digital images of specimens sampled the locations. Transformed measurements were...

Abstract The goal of this study was to assess the influence different organic fertilisers - vermicompost, mulching, Azotobacter, phosphate solubilising microbes (PSM) and Trichoderma harzianum added each year mineral containing NPK farmyard manure (FYM) on leaf nutrient status, tree growth, fruit yield quality guava grown in low fertile soil. results revealed that bio-fertilisers mulching resulted boosters, as compared application FYM only fertiliser. Significant differences plant height,...

Abstract Silonia silondia is a commercially important fish distributed in Asian countries, which under threat due to overexploitation. This study focuses on the morphological analysis and genetic variation of S. individuals, through truss network sequencing two mitochondrial regions, respectively, from six wild populations Ganga Mahanadi river systems India. A total 38 haplotypes was observed by analysing combined genes (cytochrome b + ATP ase 6/8) 247 individuals collected populations....

Fish stocks that are grown under diverse environmental conditions have different biometric relationships and growth patterns. The length-weight relationship (LWR) is an essential fishery assessment tool, as fish continuous depends on genetic factors. present study attempts to understand the LWR of flathead grey mullet, Mugil cephalus Linnaeus, 1758, from locations. area encompassed its distribution in wild across freshwater location (one), coastal habitats (eight locations), estuaries (six...

Background: Peach [Prunus persica (L.) Batsch] fruits are good source of phenolic compounds, vitamins and organic acids. Low chill peach cultivars require low chilling hour for bud burst growth. Methods: Seven four six acids were profiled in eight at edible ripe stage using HPLC-PDA evaluated multivariate analysis. Result: Gallic acid, chlorogenic acid catechin the most predominant components, ascorbic niacin major citric malic prevalent all cultivars. Though not a single cultivar possessed...
