Natural versus synthetic anesthetic for transport of live fish: A review

Abstract

An increased awareness of food safety and quality has led to an increased demand for live edible fish. This product requires effective and efficient handling technology and transport to ensure a low mortality rate, but live fish transport has not yet met this criteria. Anesthetized fish can be transported in larger quantities without being stressed during transfer, maintaining a higher quality. This paper explored synthetic and natural anesthetics derived from terrestrial and aquatic resources. This review of the different types, sources, and applications of natural and synthetic anesthetics was used to investigate the potential of seaweed as an anesthetic. In addition, advantages and disadvantages of anesthetics and the potential of seaweed as a prospect of anesthetic are discussed. Keywords: Fish anesthetic, Seaweed potential, Live fish transport
