The mandarin fish is a piscivorous fish, feeding on other fish species. It is tasty, devoid of fine skeletal spines, and fetches high price. Certain research institutes have tried to stock this fish into lakes with plenty of trash fishes, and the result seems promising.

就水体中氮、磷的负荷而论，只要输出水体的渔获物中氮、磷的含量大大超过输入水体的全部&鱼种&的氮、磷含量加上这些&鱼种&生长代谢过程中所排泄的氮磷总量，那么这种放养对延缓富营养化的进度还有积极意义

Our work reported here are aiming at improving nitrogen and water use efficiency in wheat/maize, faba bean/maize, pea/maize and soybean/maize intercropping through field experiment.The main results obtained were as the following:(1) Land equivalent ratio was greater than 1.0 for faba bean (Viciafaba L.)/maize (Zea mays L.) intercropping regardless of nitrogen fertilizer application or not. Based on grain yields production, LER of pea (Pisum sativum L.)/maize intercropping was over 1.0 in spite of nitrogen fertilizer application, while LER was higher than 1.0 only when nitrogen fertilizer was applied based on biomass production. However, LER in soybean (Glycine max L.)/maize intercropping was smaller than 1.0 both nitrogen applicationa and no nitrogen application. In wheat Triticum aestivum L.
