Elimination of "cornering" is why the cylindrical cage is often preferred. Over the full spectrum of fish species that can be raised in cages, cornering is less of a problem in cylindrical cages. Fish bunching up in corners tends to be stressful. It is important to reduce stress esp when fish are in crowded conditions.
The coated wire material was used a lot in early cage designs before plastic mesh was widely available. Wires coated and uncoated had too many problems compared to the more durable and easy to work with plastic mesh material. Thus plastic mesh is now used almost exclusively by the industry.
