Abstract:

Neolissocheilus hexagonolepis, a valuable cold-water fish species, embodies significant economic and scientific potential. The paper provides reference for further research, protection, development and utilization of Neolissocheilus hexagonolepis. Drawing upon a thorough examination of existing literature and the most recent global advancements, this comprehensive review meticulously outlines the findings about its distribution patterns, biological attributes, artificial propagation techniques, and nutritional merits. The investigation highlights key research avenues such as reproductive biology, molecular mechanisms, dietary preferences, resource assessment, nutritional significance, integrated farming practices, and the correlation between weight and length. However, amidst the escalating challenges posed by global climate change, including droughts, floods, extreme heatwaves, low temperature stress, intensified extreme weather events, and human intervention, the population of Neolissocheilus hexagonolepis is experiencing a steady decline, prompting its classification as an endangered species by the IUCN. Consequently, it is imperative to expedite breakthroughs in artificial breeding technologies for this species, establish robust systems and standards for artificial seed preservation, and harness modern biotechnology to unravel and preserve its unique genetic resources, thereby ensuring its preservation and sustainable development.
