Farming of Arctic charr mainly takes place in land‐based farms applying intensive rearing methods with relatively high production costs. Depending on local conditions at each site, it is possible to regulate important environmental factors to improve productivity and well‐being of the fish. Knowledge about how these different environmental factors affect various farming traits is important to reduce production costs. This review shows how rearing temperature, photoperiod, salinity and feeding rate can affect farming traits such as growth rate, maturation and feed conversion efficiency of Arctic charr. High growth rate during juvenile phase when the fish are reared at higher temperatures can result in higher incidence of maturation during the on‐growing period. Overall, more moderate rearing temperature regimes seem to result in better long‐term growth rates. Photoperiod manipulation and feed ration can be used as tools to improve growth and reduce maturation. It is possible to rear Arctic charr successfully up to market size in salinities up to c. 27–28 ppt. However, extended rearing resulted in higher ratio of sexually mature fish at 29 than at 25 possibly linked to higher rearing temperatures in brackish water. Future studies should focus on better preserving the potential high growth rate of Arctic charr during juvenile phase into the on‐growing period and establish protocols to improve the seawater tolerance of Arctic charr.

环境因素对养殖北极鲑生长和成熟的影响

北极鲑的养殖主要发生在土地集约化养殖场，采用集约化饲养方式，生产成本相对较高。根据每个地点的当地条件，可以调节重要的环境因素以提高鱼类的生产力和福祉。了解这些不同的环境因素如何影响各种农业特性对于降低生产成本很重要。这篇评论表明饲养温度，光周期，盐度和摄食率如何影响农业特性，例如北极rate的生长率，成熟度和饲料转化效率。在较高的温度下养鱼时，幼年期的高生长率会导致在成长期中成熟的发生率较高。全面的，较温和的饲养温度制度似乎会导致更好的长期生长率。光周期处理和进料比可以用作改善生长和减少成熟的工具。有可能成功地将北极char鱼的盐分提高到市场规模，最高可达c。27–28 ppt。但是，长期饲养会导致在29岁时有性成熟鱼的比例高于25岁时，这可能与微咸水中较高的饲养温度有关。未来的研究应侧重于在幼年阶段到成长期期间更好地保持北极炭黑的潜在高增长率，并建立提高北极炭黑的海水耐受性的方案。有可能成功地将北极char鱼的盐分提高到市场规模，最高可达c。27–28 ppt。但是，长期饲养会导致在29岁时有性成熟鱼的比例高于25岁时，这可能与微咸水中较高的饲养温度有关。未来的研究应侧重于在幼年阶段到成长期期间更好地保持北极炭黑的潜在高增长率，并建立提高北极炭黑的海水耐受性的方案。有可能成功地将北极char鱼的盐分提高到市场规模，最高可达c。27–28 ppt。但是，长期饲养会导致在29岁时有性成熟鱼的比例高于25岁时，这可能与微咸水中较高的饲养温度有关。未来的研究应侧重于在幼年阶段到成长期期间更好地保持北极炭黑的潜在高增长率，并建立提高北极炭黑的海水耐受性的方案。
