Using Artificially Induced Locomotion in the Measurement of Active Respirometry Rates from Skipjack Tuna, Katsuwonus Pelaims

The purpose of this contract was to design and construct an apparatus for utilizing artificially induced locomotion (AIL) (Kashin et al. 1981) in the measurement of oxygen uptake at various activity levels from restrained, live skipjack tuna, Katsuwonus pelamis. The AIL technique involves electrically stimulating the midbrain of the skipjack tuna causing rhythmic, coordinated swimming motions to be generated. In other fish, this technique has been shown to produce coordinated swimming behavior in a free-swimming fish when stimulating electrodes are implanted (Kashin et al. 1974). 1982 Contract (Purchase Order No. 81-ABA-2116) NMFS (National Marine Fisheries Service) SWFSC (Southwest Fisheries Science Center) Library Public Domain 1863
