This problem is solved with the introduction of our Cylinder Oyster Seeding Mesh Tumbler (28cm in diameter, 85cm in length) : Its 3mm square hole design precisely intercepts 2-5mm seedlings, preventing escape while achieving a natural rolling of 0.3-0.5 revolutions per minute with the help of Brittany tides (0.5m/s flow rate), allowing each seedling to evenly come into contact with plankton, and increasing the individual cultivation rate to 95%. To further enhance protection and operational convenience, farmers use our Oyster Bag Shark Clips to seal both ends of…
