Fish Stories by Madelaine Williams
Italian | 2020 | ISBN: n/a | 163 pages | PDF | 15.0 MB
Fish stories tell us about the unique lives of fish, many of which school, while
others exhibit extraordinary behaviours. We learn the techniques for rearing
and observing them in aquaria or in the field. The construction of an aquarium
is based on the simulation of the functioning of the natural environment, so that
it contains a filter, temperature controls and pumps for circulation of water.
Basic concepts of three fish are examined in detail, including Discus Fish,
Clownfish and Poecilids, which possess special taxonomic and ethological
characteristics The reproduction and rearing of the young are unique and
fantastic processes.
We continue with descriptions of experiments on schooling behaviour, which
demonstrate that behaviour is modified to a significant degree when the fish are
reared in atypical environmental conditions. Modifiability of schooling
behaviour in fishes was investigated in Menidia menidia from the embryonic stage
to the schooling stage.
