Prey [relation/link] - predator.
Most [all] biologist assume that predator altogether species of carnivora, including fish eater of fish ( Piscivor) and eater all kinds of invertebrate start from king sized small fairish until. According to Campbell ( Weatherley and of Gill, 1984) there [is] 11 principle concerning [relation/link] prey and goose [at] fish:
1. Fish of Piscivor harvest the more fish from [at] fisherman
2. Mean prey size measure eaten by predator progressively growing larger by growing larger predator size measure
3. [All] predator show hobby [at] species prey [at] certain size measure
4. Predator generally take all kinds of prey
5. Preying prey by conducive predator [of] them change exploitation in density of prey.
6. Predator species possible change its food more or less permanently to species in is balance [of] ecology
7. Prey its amount [is] reduced clearly by predator pressure
8. Community prey composition influenced by predator
9. big population of prey can stimulate growth and density of predator.
10. Emulation [among/between] predator species can influence growth and [its] density.
11. Certain predator, by degrading emulation among prey species, possible generate addition of prey community variety.
