Hejnové chování jako odezva na změny prostředí, přehledová studie
JAKŠ, Jiří
The aim of my bachelor thesis was to create a review about effect of some parameters on shoal of fish. In my thesis may be found information about effects of different parameters on shoal of freshwater, marine and aquarium fish species. Review describes several parameters that effect fish in several ways and it is also contains a lot of information about shoal behaviour in general. Review gradually passes from general definition of shoal, creation of shoal, types of shoal, advantages and disadvantiges of shoal, communication and recognizing of fish inside the shoal, to enumeration of parameters that effect fish both positively and negatively. In conclusion may be found possibilities of modeling fish and their behaviour on two model examples. Information come from Czech literature, but also from foreign literature, which makes my thesis more creative and objective. Shoal behaviour is still relatively unexplored topic and many questions still remain unanswered. Exploring and assesing of shoal behaviour is relatively complicated, therefore the answers are only author´s opinions and several experiments results. Although there are speculations about this topic, many authors and experiments have similar opinion. My bachelor thesis may appreciate those, who want to know more about the shoal behaviour. In future it is necessary to realize more research about shoal behaviour and fish modeling because of its use and and less public awareness.
