Proteomics is a very advanced technique used for defining correlations, compositions and activities of hundreds of proteins from organisms as well as effectively used in identifying particular proteins with varying peptide lengths and amino acid counts. In the present study, an endeavour has been put forth to create muscle proteome expression of snow trout, Schizothorax labiatus. Liquid chromatography-mass spectrometry (LC-MS) using label free quantification (LFQ) technique has extensively been carried out to explore changes in protein metabolism and its composition to discriminate across species, clarify functions and pinpoint protein biomarkers from organisms.

Article Synopsis
  • Molecular characterization of fish muscle proteins is important for understanding their physiological and metabolic roles, especially in coldwater fish like snow trouts that adapt to temperature fluctuations.
  • The study used liquid chromatography mass spectrometry to analyze the muscle proteins of Schizothorax labiatus from river Sindh, identifying significant differences in protein expression between male and female fish across two weight groups.
  • Results showed specific proteins that were either down-regulated (e.g., homeodomain protein HoxA2b) or up-regulated (e.g., gonadotropin I beta subunit) in both groups, providing insights into the protein profiles that support their survival in varying temperatures.

The purpose of this research is to see how sex affects several haematological, biochemical and blood cell morphology in cultured brown trout, . Different haematological parameters, for instance haemoglobin (Hb) concentration, haematocrit (Hct), red blood cell (RBC) and white blood cell (WBC) counts, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) and serum biochemical parameters such as glucose, cholesterol, total protein, albumin, globulin, alanine aminotransferase (ALT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), sodium, potassium and phosphorus were analysed. Throughout the study period, male fish had considerably greater Hb content, RBC count and Hct content than female fish, but insignificant (P > 0.

The current investigation was carried out with an aim to evaluate disparity in haematological and serum biochemical parameters of healthy male and female Schizothorax labiatus with respect to its four reproductive phases, i.e. preparatory (autumn), pre-spawning (winter), spawning (spring) and spent (summer).

Today, there is a growing awareness about the importance of eating nutritious foods and fish is gaining momentum as a result of its unique nutritional benefits. Fish are considered as nutritionally valuable part of the human diet because of the presence of both macronutrients (proteins, lipids and ash) and micronutrients (vitamins and minerals). These nutrients are indispensable in human nutrition and have proven to be involved in several metabolic functions.

Haematological and serum biochemical parameters are a valuable tool in determining the wellbeing status of different fish species and response in close association to various biological and environmental factors, therefore the aim of the present study was to establish sex-wise reference values of haemato-biochemical parameters of S. labiatus. The haematological parameters such as haemoglobin (Hb) concentration, total erythrocyte count (RBC), total leucocyte count (WBC), packed cell volume (PCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), mean corpuscular volume (MCV) and serum biochemical parameters such as glucose, cholesterol, urea, total protein, albumin and globulin were analysed.
