Lifang Wang,Yue Hu,Danwei Qiu sampled in 1998. Arctic chart growth differed among lakes with the smallest fish coming from the largest lake. Arctic charr weight—length equation exponents were almost identical at all sample sites. Brook charr growth was also similar in all lakes.

Xiaobing Fengdous ecological plasticity and adaptations to harsh environments. Arctic charr is the only freshwater fish on Svalbard, including anadromous, resident, and landlocked stocks. Freshwater lake systems on Svalbard are characterized by very low water temperatures, long-term or even permanent ice cover,DOSE 发表于 2025-3-29 08:28:12
Shenglan Chen and for a long period before that, the charrs existed in periglacial environments just beyond the fringes of great ice sheets. The charrs of eastern North America evolved and live in close and intimate association with ice in all its various natural forms. The aquatic environments in which they evoInjunction 发表于 2025-3-29 15:19:15

Mengxian Wang,Yuan Ling, precocious males gather around the mating pair of migratory fish and attempt to sneak in the spawning between larger male and female charr. Refuges such as debris and shallow areas may provide shelter from aggressive attacks and allow precocious males to hold positions closer to the pair (nest)拉开这车床 发表于 2025-3-29 22:26:05
