精准水温调控对三文鱼性腺发育及鱼白品质形成的影响机制

Effect of Precise Water Temperature Regulation on Gonadal Development and White Quality Formation in Salmon

摘要

本文聚焦水温调控技术在三文鱼（大西洋鲑，Salmo salar）鱼白（精巢）高效养殖中的关键作用，系统分析水温对三文鱼性腺发育、精子质量及繁殖效率的影响机制。通过构建精准水温调控体系，结合不同生长阶段的温度需求，探究其对鱼白产量、精子活力、受精率等核心指标的优化效应。结果表明，适宜的水温调控可显著促进三文鱼性腺成熟，提升精子密度与活力，降低畸形率，同时缩短繁殖周期，提高鱼白生产效率。本研究为三文鱼鱼白规模化养殖提供理论依据与技术支撑，推动冷水鱼类高附加值产品的绿色高效发展。

Abstract

This study focuses on the critical role of water temperature regulation technology in high-efficiency salmon (Salmo salar) roe (testis) farming, systematically analyzing the mechanisms by which water temperature influences gonadal development, sperm quality, and reproductive efficiency. By establishing a precision temperature control system tailored to temperature requirements at different growth stages, we investigated its optimization effects on key indicators including roe yield, sperm motility, and fertilization rates. Results demonstrate that optimal temperature regulation significantly promotes gonadal maturation, enhances sperm density and motility, reduces malformation rates, shortens reproductive cycles, and improves roe production efficiency. This research provides theoretical foundations and technical support for large-scale salmon roe farming, advancing the green and efficient development of high-value-added products from cold-water fish species.
