What are the applications of licorice extract in aquaculture?

Licorice extract has been gaining popularity in the aquaculture industry due to its numerous applications and benefits. This natural substance is derived from the roots of the licorice plant, which is native to the Mediterranean and parts of Asia. Licorice extract has been traditionally used for medicinal purposes, but its use in aquaculture has been gaining momentum in recent years.

One of the primary applications of licorice extract in aquaculture is as a natural feed additive. The licorice extract glycyrrhizin, which is a natural sweetener that can enhance the palatability of feed for fish and other aquatic animals. This can be particularly useful in situations where fish are reluctant to eat or when transitioning to a new feed. In addition to improving feed intake, licorice extract can also boost the growth and overall health of fish.

Licorice extract also has antibacterial and antifungal properties, making it an effective natural treatment for diseases and infections in fish. The extract contains compounds that can inhibit the growth of harmful bacteria and fungi while promoting the growth of beneficial bacteria in the gut. This can help prevent and treat common diseases in fish, such as bacterial infections, fin rot, and swim bladder disease.

Another potential application of licorice extract in aquaculture is as a natural water treatment. The extract contains saponins, which are natural surfactants that can help reduce surface tension and improve water quality. This can be particularly useful in recirculating aquaculture systems (RAS), where water quality is critical for maintaining the health and growth of fish.

Licorice extract has also been shown to have anti-stress properties, which can be beneficial for fish during transportation and handling. The extract contains compounds that can help reduce cortisol levels and alleviate stress in fish. This can help prevent stress-related diseases and improve survival rates during transportation and handling.
