Title: Studies on low temperature resistance and nutritional needs of Scatophagus argus juveniles
Abstract: In the process of cultivating marine fish,temperature tolerance and nutritional requirement are the main factors for consideration.In the current study,we performed the experiment of low temperature resistance in Scatophagus argus juveniles and proved that LT50 is about 12.2 ℃ and the lethal low temperature is 11.0 ℃ for this species.In addition,experiments about nutritional needs of Scatophagus argus juveniles were also carried out in this study.Through feeding Scatophagus argus juveniles with three different kinds of feed,the results showed that the group fed with plant protein grew significantly faster than the other two groups fed with animal protein(P0.01).We also observed that Scatophagus argus preferred the synthetic feed made from plant protein.It proved that Scatophagus argus required less animal protein compared with other economic fishes,which suits the aquacultural trend of low carbon economy.Our studies can benefit the regulation and controlling of water temperature and nutritional requirement in the mariculture of Scatophagus argus.
