Human beings may affect the welfare of fish through fisheries, aquaculture and a number of
other activities. There is no agreement on just how to weigh the concern for welfare of fish …

The fish gustatory system provides the final sensory evaluation in the feeding process.
Unlike other vertebrates, the gustatory system in fish may be divided into two distinct …

In contrast to other major forms of livestock agriculture, there is a paucity of scientific
information on the welfare of fish raised under intensive aquacultural conditions. This …

Seasonality is an important adaptive trait in temperate fish species as it entrains or regulates
most physiological events such as reproductive cycle, growth profile, locomotor activity and …

Complex brains and behaviors have occurred repeatedly within vertebrate classes
throughout evolution. What adaptive pressures drive such changes? Both environmental …

We provide selected examples from the fish literature of phenomena found in fish that are
currently being examined in discussions of cognitive abilities and evolution of neocortex size …

Most fishes experiencing challenging environments are able to adjust and adapt their
physiology and behaviour to help them cope more effectively. Much of this flexibility is …

The size and structure of an animal's brain is typically assumed to result from either natural
or artificial selection pressures over generations. However, because a fish's brain grows …

Most biomedical research is performed using a very limited number of “model” species. In
part, this has resulted from a combination of full genomes, manipulation of genes, and short …

Several patterns of brain allometry previously observed in mammals have been found to
hold for sharks and related taxa (chondrichthyans) as well. In each clade, the relative size of …
