Along the coast of Brittany, France, local farmers have long been troubled by the "clustering and sticking" of oyster seedlings - in
traditional fixed cages, 20% of the seedlings have deformed shells due to overlapping, and the survival rate is only 65%. 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 the roller cage - compared
with traditional knots, the shark clips can save 70% of the assembly and disassembly time, and remain undamaged for 3 years in the corrosive
environment of seawater; An additional layer of HDPE Oyster Mesh Bags was wrapped around the periphery to effectively prevent barnacle
larvae from attaching. Combined with a high-pressure water gun rinse once a week, the biofilm attachment rate was reduced by 80%, and the
survival rate of the seedlings eventually stabilized at over 90%, an increase of 25 percentage points compared to before.
Chesapeake Bay, USA Case: Adult Oyster Rapid Cultivation & Synergistic Efficiency of
8mm Tumbler + Supporting Products
Oyster farms in the Chesapeake Bay of the United States focus on the "6-month rapid growth" model, with the core demand being to
enhance water exchange efficiency and the quality of the adult body. Our 8mm hole cylindrical roller cage has become a key piece of
equipment: the 8mm square hole not only ensures the activity space for adult oysters (shell length 15-20mm), but also achieves over 90%
water exchange, guaranteeing sufficient dissolved oxygen. The HDPE material of the roller cage is added with UV stabilizer, which does not
deform under the 40℃ summer sun exposure in North America and has a service life of up to 5 years (far exceeding the 2 years of traditional nylon cages).
The farm has also established a complete chain of "rolling cages + temporary rearing" : After being harvested from the rolling cage, the adult
oysters are transferred to our Hexagonal Oyster Baskets for 72 hours of temporary rearing. The hexagonal structure of baskets ensures even
distribution of the oysters, and combined with the circulating seawater containing probiotics, it can purify intestinal impurities and enhance
the sweetness of the meat. The final product has a 30% premium in the North American fresh food market. Furthermore, the farm uses our Chicken Fence
Installation Kit (including HDPE cable ties and ground stakes) to fix the rolling cage raft, enhancing its wind and wave resistance to withstand gusts of force
10 and solving the equipment safety problem of frequent typhoons in the Chesapeake Bay during summer.
