常说:“鱼儿离不开水,瓜儿离不开秧”。要搞好养鱼,首先要懂得水,懂得水中有些什么,它们的性质,以及相互之间的关系。用科学的语言来说,就是要懂得水域生态系统的基本知识。所谓水域,都由生物和非生物两种因素构成。非生物因素,是指水,底泥,进入水域的光和热,以及溶解气体和营养物质。生物因素比较复杂,有一个独特的系统。概括地说,它包含着“生产者”、“消费者”和“分解者”三个部分。

Often said: “fish can not do without water, melon children can not do without seedlings.” To do a good job of fish farming, we must first understand water, know what is in the water, their nature, and the relationship between them. In a scientific language, we need to understand the basics of a watershed ecosystem. The so-called waters, both by the biological and non-biological factors. Abiotic factors are water, sediment, light and heat entering the water, and dissolved gases and nutrients. Biological factors more complex, there is a unique system. In a nutshell, it contains three parts, “Producer”, “Consumer” and “Decomposer.”
