摘要: The diversity of food resources available to fish is larger than for any other group vertebrates (Nikolsky, 1963). Its wide variety in size, shape, location, movement, physical and chemical properties leads one expect specializations architecture, functioning food-handling behaviour species order optimize feeding on specific types while unavoidably limiting the use others. Fish-food interactions largely depend how efficient each at foraging particular items; efficiency ultimately determined by food’s abundance, escape ability characteristics (Chapter 12), as well apparatus, it functions its versatility.
