The blind cave fish differ from their surface relatives in several notable ways.
Regardless, all hatchery fish differed from naturally spawned fish in two important ways: their parents were bred artificially without natural patterns of sexual selection or mate choice, and they were reared in a controlled setting rather than a river from fertilization until their release.
In similar studies with Atlantic salmon, lower survival of hybrid and backcross offspring between farm (domesticated) and wild fish relative to wild fish has been observed (McGinnity et al. 2003), although in these studies the pure farm parental cross also had reduced survival relative to the wild fish (differing from the present results).
The telencephalon of actinopterygian fishes differs from that of other vertebrates in consisting of a pair of solid lobes.

Precedence for multiple isoforms of a T cell co-receptor is shown by the two CD4-like genes in fish which differ from each other structurally [ 58, 59].
Therefore, herbivorous, detritivorous, omnivorous and carnivorous fish species differ from each other in terms of the presence or absence of a stomach, the length of the intestine (from 1 to more than 20 times the body length), number and presence of pyloric caeca, intestinal loops and valves (13).
Second, gene ontology enrichment analysis is mainly based on the annotation and comparison of lists of differentially expressed genes with data that is biased towards a few (mainly mammalian) model organisms and the involvement of a particular protein in biological processes in fish may differ from that in those species [ 34].
Since offshore zooplankton and fish communities strongly differ from inshore species [25], [28], our methodology does not seem to be affected by changes in the communities composing acoustic scatterers.
Because coral community development is mainly restricted to the bank's outer rim, fish assemblages likely differ from those occurring on the inner bank lagoon (Figure 1) that is characterized by horizontal limestone pavement on which mainly macroalgae and gorgonians are found.
