How long does it take to get pearls and what is the survival rate?

After implanting the nucleus, a freshwater mussel generally takes well over a year, often around 12 to 18 months or more, to coat it into a sellable pearl, and design pearls may differ in time. The honest catch is mussel survival, because a meaningful share of mussels die after surgery or fail to form a good pearl, and the exact survival depends heavily on your surgical skill, water quality and aftercare. Beginners often see high mortality. This long wait and uncertain survival is why pearl farming is riskier than the guaranteed profit ads claim. Maintain good water quality throughout and learn proper post surgery care. Get realistic survival and quality expectations from a training institute or your Fisheries department rather than from sellers.
