The importance of morphological changes during ontogeny in explaining dietary changes was shown because 75% of the variation in the first, and most important, morphological principal component was accounted for by differences between size-classes.
Changes in the demersal fish assemblage in the south-eastern North Sea following the establishment of a protected area (‘‘plaice box’’)
Principal component analysis does indicate that a considerable proportion of the variation in the abundance of the large fish over the years can be explained by a higher abundance in the ‘‘box’’ area than in the reference area of most fish species, including the two main commercial species plaice and sole.
Cause and identification of taste and odour compounds in water.
An ecosystem perspective for the management of a tropical reservoir fishery
Two complementary ecosystem approaches (hierarchical food web and biomass size spectrum) are used to analyse the structure and functioning of the Tissawewa ecosystem and propose different options for improving fisheries management in tropical reservoirs.
Diel variation in feeding and vertical distribution of ten co-occurring fish species: consequences for resource partitioning
The status of whether or not a fish is feeding determines if the trophic and spatial resource dimensions are interrelated and resource partitioning along the spatial dimension may reduce exploitative competition at the time of feeding, whereas it may limit interference competition or predation during non-feeding periods.
