The IATTC Achotines laboratory is the only facility in the world to report 25 years of yellowfin supported spawning
Inter-American Tropical Tuna Commission (IATTC) reports reaching 25-year milestone of sustained yellowfin spawning in its Achotines laboratory
LA JOLLA, CA, UNITED STATES, November 26, 2021 /EINPresswire.com/ – The Inter-American Tropical Tuna Commission (IATTC), a regional fisheries management organization based in La Jolla, Calif., Announces that it has passed 25 years spawning of yellowfin tuna to his Achotines Laboratory in the Republic of Panama. IATTC’s Early Life History (ELH) group conducts yellowfin spawning research. The almost daily spawning of yellowfin at the Achotines Laboratory represents the only sustained spawning of yellowfin in captivity in the world.
Yellowfin spawns at the Achotines Laboratory in an underground concrete tank (17 m in diameter x 6 m in depth, 1,362 m3 in volume). In 1994, an expansion of the Laboratory’s seawater reservoir and system, financially supported by the IATTC and the Overseas Fishery Cooperation Foundation (OFCF) of Japan, enabled research studies on yellowfin tuna. at the Laboratory. Yellowfin began to spawn in the terrestrial basin in October 1996.
The yellowfin spawning program supports research on the reproductive biology of adult tuna as well as early life stage investigations. The ELH group conducts ecological experiments to estimate the effects of biotic and environmental factors on yellowfin eggs, larvae and early juvenile stages and uses the results to develop models of early life growth and survival. prior to recruitment to the tuna fisheries in the eastern Pacific Ocean. Captive yellowfin spawning also supports laboratory studies of the effects of climate change on the life stages of pre-recruits.
Studies of yellowfin growth and survival during the early stages of life have strong application to tuna ecology and aquaculture. Improving the success of early yellowfin tuna rearing at the Achotines laboratory now provides the opportunity to experimentally study all life stages of pre-recruits (age 0-6 months) and supports potential completion of the rearing the entire life cycle of yellowfin in the laboratory.
