Shrimp and Tiny Plastic: A Hidden Danger in Our Oceans

The Problem of Microplastics

Plastic pollution is a significant issue in our oceans. Tiny plastic pieces, known as microplastics, are pervasive. But how do they affect sea life?

Recent Study on Shrimp

A recent study investigated the effects of polyethylene microplastics—tiny plastic spheres—on young shrimp.

Methodology

• Duration: 28 days
• Diet: Shrimp were fed different amounts of microplastics:
• 0 mg/kg
• 30 mg/kg
• 75 mg/kg
• 150 mg/kg

Findings

• Growth and Survival: Not affected by microplastics.
• Accumulation: Microplastics accumulated in the shrimp's digestive system.
• Highest Concentration: Found in the gastrointestinal tract and liver-like organ.
• Digestive Tissue Damage: More severe in shrimp that consumed the highest amount of microplastics.

Conclusion

While microplastics did not kill the shrimp, they caused internal damage. This underscores the need for further research on:

• Different types of plastics
• Various shapes of microplastics
• Longer exposure times
