摘要
鱼类食性和食物网的研究对于了解鱼类群落的结构与功能具有重要意义。本文主要结合国内外有关鱼类食性和食物网研究的报道 ,概括性叙述了在进行鱼类的食物组成、食性比较、摄食的时空变化、摄食的选择性、营养级、摄食量、食物网及其营养动力学研究时所使用的方法 ,并对我国开展此类研究的前景和存在的问题进行了讨论。
The study on the feeding habits of fishes and food webs is fundamental to understand the structure and function of fish communities. Based on many reports on the diets of fishes at home and abroad, the present paper reviewed the methods commonly employed in the studies on the food webs and on the food composition, diet comparison, spatio temporal changes in diets, feeding selectivity, trophic level and food consumption of fishes. The prospect of such studies in China and some existing problems are also discussed.
