[Method] The ef- fective constituents of live natural foods, including chironomid larvae, earthworm, mussels, winkles, were separated by using soaking solution extraction and centrifu- gal extraction. The extracted live foods were used to attract the carp, young cru- cian, and fishes of 100-150 days old and over 1 year old, respectively. The feed nutrition formulation of the added food attractants was designed and applied to feed- ing in the aquaculture farm. The test results were practised in bait study to conduct field fishing test and collect the data. [Results] Compared with the control group, feeding with live foods had significantly improved the growth rates of fishes at dif- ferent ages, and greatly reduced food coefficients. [Conclusion] The feeds made from live food addictives had excellent attraction ability, which not only reduced the negative effects on natural environment but also made the aquaculture mode more organic and greener.展开更多

The paper highlights the core issues of the concept and its structural constraints. Several constraints of a far-reaching realization of a Green Economy are presented, and one constraint is highlighted, i.e., the imperial mode of （production and） living. The latter gives emphasis to the continuous and largely unquestioned access to products produced by cheap labor and under environmentally problematic conditions. This mode of living, the paper argues, is also attractive among the upper and middle classed in countries with emerging economies like China. Moreover, it compares it with the concept of sustainable development which emerged some 15 years ago. Like sustainable development, proposals for a Green Economy might become ＂a tranquilizing dis- positive＂ in order to silence doubt and criticisms. However, it is argued that, despite the improbability of realizing the ambitious objectives, the Green Economy strategy might contribute to further capitalist development. Environmental issues might be integrated into the mode of production and living. However, given capitalist and imperial structures and dynamics, this will occur in highly selective and partial ways. The author calls this emerging constellation and possible new mode of development in some countries or regions of the world Green Capitalism.展开更多
