Ways have been developed to breed these fish species in ponds using hormonal stimulation, ensuring the consistent supply of pure fish seed in desired quantities.

Fish seed collected from the wild may not only be irregularly available but can also be mixed with seed from other species, leading to unpredictability and potentially compromising the genetic purity of the desired species.

Irregular availability of fish seed can disrupt production schedules and limit the ability of fish farmers to maintain consistent production levels.

Oysters are also cultivated for the pearls they produce, adding to their economic value beyond just being a food source.

The practice is called mariculture, where marine organisms are cultivated in controlled environments in seawater.
