近年来,在日常的养殖生产过程中,“应激反应”一词越提越多,对水产养殖业造成的损失也逐年增加。应激反应是指机体在受到各种内外因素刺激时所出现的非特异性全身反应。1应激反应的产生因素苗种质量差,体质弱;水体中溶解氧含量过低;氨氮、亚硝酸盐含量过高;pH值的突然变化,忽高忽低;水温的剧烈变化:刺激性药物的使用;惊吓(搬苗、打样等引起);水质污染(底质突变、盐度变化);大量换水、添水;机械、网具等损伤。
In recent years, in the daily farming process, the word “stress response” has been increased, and the losses caused to the aquaculture industry have been increasing year by year. Stress refers to the body when subjected to a variety of internal and external factors arising from the stimulation of non-specific systemic reactions. A stress response factors seedling poor quality, physical weakness; dissolved oxygen in the water is too low; ammonia nitrogen, nitrite content is too high; sudden changes in pH, fluctuated; dramatic changes in water temperature: Irritability Use of drugs; frightened (moving seedlings, proofing caused); water pollution (sediment mutation, salinity changes); a lot of water, water; machinery, nets and other injuries.
