Abstract： In order to optimize the live transport conditions of Larimichthys crocea, its ecological ice-temperature was explored, the effects of fish/water mass ratio and holding time on its keep-alive time was analyzed, and an orthogonal experiment of 3 factors and 3 levels was designed to find suitable conditions for keeping Larimichthys crocea alive. The results showed that the ecological ice-temperature of Larimichthys crocea was -2°C ~7°C; fish/water mass ratio and holding time had significant effects on the keep-alive time of Larimichthys crocea (P<0.05); the keep-alive time could be over 19h when the temperature was 5~7°C, the fish/water mass ratio was 1:4 and the holding time was 48h. The results could provide references for live transport of Larimichthys crocea.
