The amur ide, a fish species endemic to China's saline Dali Nur lake, is battling for survival as it undertakes its annual spawning migration upstream to find a habitable water for laying eggs.
Vast shoals of the small freshwater fish crowd together fighting their way against the flow on a perilous journey of up to 60 kilometers to spawn in the Gonggeer River, which is in the upper reaches of Dalai Nur.
Where there is an obstacle, the amur ide will jump up to half meter out of the water.
"The water in Dalai Nur has a much higher salinity and alkalinity compared with regular river water. And we found that the fish egg envelopes will soon shrink inside the lake water because of this hypertonic environment, and then there will be some developmental abnormalities like malformation. So in general, river water is critical for Amul ide fish -- it has to go into the river to breed," said Wang Ruifang, a professor of aquaculture at Inner Mongolia Agriculture University.
The fish migration also aids exhausted migratory birds that rely on them for nutrients after long flights, aguaculture experts say.
For the amur ide, this year's migration season lasts around a month and is nearing its end, according to local authorities. Efforts have been made by local environmental authorities to dredge rivers to ease their passage.

Flights resumed at Damascus International Airport on Tuesday after a month-long suspension following the fall of Bashar al-Assad's government, bringing a sense of optimism for a brighter, more peaceful future for Syrian citizens.
The first outbound flight was scheduled to depart Tuesday for the United Arab Emirates while an incoming flight from Qatar landed later in the day, marking the first time that a commercial flight landed in the Syrian capital during the political transition.
It was also the first time a Qatari commercial craft has flown to Syria in 13 years. The airport was closed amid a turbulent political transition, but with security conditions improved, a decision was made to reopen it.
"Our airspace is stable with no aircraft out of control. We encountered such violations in the first few days then we coordinated to solve this issue, and now the Syrian aerodrome control tower is controlling the entire Syrian airspace. The civil planes are flying in their aerial corridor as usual," said Ashhad Salibi, chairman of the Syrian General Authority of Civil Aviation and Air Transport.
The rehabilitation of the airport was prioritized for humanitarian aid flights from some Arab countries, to alleviate the economic hardships that Syrians have been experiencing for years.
"What happened today will mitigate the suffering of the Syrian people, who used to take other countries' airports due to the closure of Damascus and Aleppo airports. That used to cost them more and made them exert more efforts, but now Syrians can take Damascus international airport to leave or to come," said Salibi.
The reopening of the airport is regarded as a "historic" moment by Syrians, many of whom have been abroad for a long time under the shadow of the political chaos.
"The trip was awesome. For me, it is a historic moment that I can't really describe how nice it is. It is been a long time of being abroad and now we are looking forward to the new Syria," said Syrian returnee Ziad Harb.
Damascus International Airport serves as a critical hub for Syria's connectivity to the wider region. Its reopening is seen as a symbolic step towards rebuilding and stabilizing the country's infrastructure.
