Reporting Of Fish Escapes, Causes Crucial Step In Developing Better Controls

摘要

Escapes of fish from farm facilities can lead to interbreeding and competition for mating opportunities with wild fish. Escapees may also transmit diseases and parasites, as well as compete for feed and space. In fish hatcheries and land-based growoutfacilities, escapes are fairly well controlled by physical and physico-chemical barriers. Additional engineering solutions, including biological approaches, have been investigated for sea cage systems. More efforts are required to prevent farm fish escapements, however. An initial step is to systematically document escapes and their causes.
