What would happen to a fish if it were stuck in plastic bag?

Plastic bags are not permeable to air, which means that fish trapped inside quickly run out of oxygen. Without oxygen, they suffocate and eventually die.

Physical Damage:

Being stuck in a plastic bag can cause physical damage to fish. The bag's material can scrape and injure their delicate scales and fins. Additionally, the bag's constriction can restrict their movement, causing further stress and discomfort.

Stress:

The experience of being trapped in a plastic bag is highly stressful for fish. The combination of suffocation, physical discomfort, and disorientation can lead to a stress response that affects their immune system and overall health. Stressed fish are more susceptible to diseases and infections, which can ultimately contribute to their decline.

Starvation:

Fish trapped in plastic bags cannot feed themselves. Without access to food, they gradually starve and become malnourished. This further weakens their immune system and increases their vulnerability to health issues.

Water Quality Deterioration:

As the fish breathes and releases waste in the confined space of the bag, water quality rapidly deteriorates. The accumulation of ammonia, carbon dioxide, and other waste products creates a toxic environment that further harms the fish's health.
