What Happens to Fish Swimming in the Lake During Temperature Changes and Survival?

Fish can survive in ice-covered lakes because the ice keeps the water insulated. However, low oxygen levels can lead to winterkill, which causes fish deaths. Fish may also get trapped in cracks. Sudden temperature changes can harm cold-blooded fish, affecting their survival. Proper conditions are essential for their health. As temperatures fluctuate, fish may seek … Read more

What Happens When a Saltwater Fish is Placed in Fresh Water? The Shocking Truth

Saltwater fish cannot survive in freshwater because of osmosis. Their bodies have a high salt concentration. In freshwater, water enters their cells, causing them to bloat. This swelling can rupture cells and lead to death. Therefore, saltwater fish are specially adapted to live in salty aquatic environments only. The shock from rapid water influx can … Read more

Freshwater Fish in the Ocean: Survival Challenges and Environmental Consequences
