Finally, a duplication has been detected in some fish species (see also Figure 8).
It was shown that dietary fatty acids can influence the expression of stress response associated genes in some fish species, such as steroidogenesis acute regulatory protein (StAR) [ 49].
Mercury and dioxins, in particular, have been found in high concentrations in some fish.
This white alone could replace almost full wine lists in some fish restaurants.
An indirect-emission type of luminous organ is present in some fish.
Swim bladders are a special organ in some fish that controls their buoyancy like ballast in a ship.
In some fish the reduction in body size was related to juveniles' making up an increased proportion of the population.
Although the MPO gene has been identified in some fish species, the structure and functions of the protein remain to be determined in these vertebrates.
In some fish dishes, for instance, the resident bacteria digest amino acids and spit out ammonia, which acts as a preservative.
Scientists suspect that this reduction is mediated by omega-3 fatty acids, which are present in large amounts in some fish.
The data also helps to explain the extreme decline in some fish stocks: the UN's Food and Agriculture Organisation (FAO) says one-third of commercial fish stocks are being caught at unsustainable levels.
