Many fish species respond to low temperature by inducing mitochondrial biogenesis, reflected in an increase in activity of the mitochondrial enzyme cytochrome c oxidase (COX). COX is composed of 13 subunits, three encoded by mitochondrial (mt)DNA and 10 encoded by nuclear genes. We used real-time PCR to measure mRNA levels for the 10 nuclear-encoded genes that are highly expressed in muscle. We...

In veterinary practice, buoyancy disorders are common in goldfish, often having a sudden onset and present floating at the surface or lying on the bottom. Fifty eight affected fish were examined in detail over a period of 11.5 years, of which 47 were goldfish: there were almost equal numbers of short-bodied and long-bodied goldfish. In many cases, there were no external lesions and no consisten...

To capture a multidimensional consistency feature of integrable systems in terms geometry, we give condition called geodesic compatibility implying the existence integrals involution flow. The is constructed from concrete example namely Calogero's goldfish system through Poisson structure and variational principle. geometrical view gives compatible parallel transports between two different Hami...

Experiments were designed to determine the rate of gain of heat-tolerance for three different groups of goldfish, Carassius auratus, respectively acclimated to 4°C., 12°C., and 20°C., and subsequently moved to a temperature S°C. higher. The rate of change of heat-tolerance showed a marked difference in the three greups, twenty or more days being required for complete acclimation in the 40C. gro...
