中文摘要:
      稻田养鱼,全国各地获得鱼、稻双丰收的事例已屡见不鲜,但是关于稻田养殖非洲鲫鱼[Tilapia moss-ambica(Peters)]的实践和研究,仅在开始。有人认为稻田养非洲鲫鱼,会影响稻作产量;也有的人却提出非洲鲫鱼在田中能消除害虫而促进稻谷丰产,这一论争尚未定论。为此,作者于1962~1964年就稻田养非洲鲫鱼与稻谷生产的关系问题作了初步研究,以厦门大孛农场和坂头水库试验田为基地,并对水域的理化性质及其生物环境进行逐月调查。现将材料作初步的综合整理,以供生产上及迸一步研究时参考。
英文摘要:
      Rearing of Tilapia mosambica in the rice fields and the correlation between the fishes andthe rice plants, has been studied during the years of 1962-1964 in Amoy, Fukien Province.The physical, chemical and biological environments of the rice fields have been observed andmeasured once a month. The physical properties of the rice fields differ greatly with those of fish ponds. ButTilapia adapts itself favorably to these shallow water environments. The chemical properties of the rice fields are basically good for fish stocking. Dissolvedorganic matters are plentiful in the rice fields. The content of inorganic salts (NO3, PO4,SiO3) in the fields stocked with fishes, are much higher than the fields not stocked. It isaffected by the excrement of the fishes. A large number of aquatic organisms inhabits the rice fields. 99 species of plankton,34 species of aquatic plants, and 17 species of bottom dwelled invertebrates and insects havebeen collected and observed. Most of them are directly or indirectly used as food by theTilapia. The average yield of fish from rice fields in four months of rearing, is 170 kg. perhectare. When stable manure is added, the production can be increased to 206-315 kg. perhectare. Besides, an additional production of few ten thousands of Tilapia fries have beenreproduced during the months. Regarding the growth of the rice plants, those in the fields stocked with Tilapia growsmuch better than in the fields without fish. And the yield of rice of the former is 3.0-13.2%greater than the latter. The experiment shows that the rearing of Tilapia mosambica withgrowing rice has a beneficial effect on rice production.
