Formaldehyde-induced fluorescence reveals numerous serotonin-containing cells within the primary epithelium of the fish gill. These cells are isolated or clustered and are supported by the epithelial basal lamina. They never reach the external medium and are found on the internal side of the primary lamellae, facing the respiratory water flow. With the electron microscope, these cells are found to contain dense-cored vesicles (DCV) of 80–100 nm. Nerve profiles are consistently found close to DCV cells. After having crossed the basal lamina, nerve fibers form endings on DCV-containing cells. These endings display both small clear vesicles and DCV and are in direct contact with DCV cells. Specific membrane alterations are suggestive of efferent synapses. These cells are considered neuroepithelial cells, similar to those found within the wall of lung airways in mammals and submammalian vertebrates. Structure and localization are suggestive of a tissue O2 sensor.

Fish bioconcentration factors (BCF) are used for the prediction of the environmental effects of new chemicals and some studies have suggested that they can be predicted from the Physico-chemical properties of the chemical. The rigorous use of pesticides resulted in the dispersal and persistence of pollutants throughout the ecosystem. Pesticides contamination in the aquatic ecosystem has become one of the most staggering issues due to their detrimental effect on public health and the environment. This study aimed to investigate the bioconcentration factor of pesticides monocrotophos and quinalphos in three tissues (skin, muscles, gills) of the fish Channa striatus for 21 days, of the three analyzed tissues of monocrotophos exposed fish, gill accumulated highest concentration of (0.033 mg kg-1) while muscles (0.012 mg kg-1) at the lowest, whereas the concentration of quinalphos was maximum (0.98mg kg-1) in liver and minimum (0.074 mg kg-1) in muscle. Results showed that the effect of pesticide differs from tissue to tissue. However, the levels exceeded maximum detection limits as recommended by U.S. Geological Survey National Water Quality Laboratory, Denver, Colo.  Hence it is suggested that the fish containing pesticide residues beyond permissible limit should be avoided for food purposes.

The frog Rana pipiens takes up Ca2+ against an electrochemical gradient from dilute external solutions that are similar to natural freshwater environments. The influx is dependent upon external [Ca2+] and is saturable. Kinetic analysis yielded a Km of 0.625 mmol l-1 and a Jmax of 38 nmol cm-2h-1. These kinetic variables suggest that both the affinity and capacity are smaller than those for Na+ and Cl- transport in the skin of the same species. They are also smaller than those for Ca2+ transport in fish gill. A significant portion (20-25%) of the Ca2+ entering a frog remains in Ca(2+)-rich layers of the skin, with ventral skin containing about three times as much Ca2+ as dorsal skin. There are seasonal rhythms in Ca2+ exchange: although Ca2+ influx does not vary significantly over the year, efflux is minimal in July, while net flux, which is negative most of the year, appears to be positive in July. Since these fluxes do not include dietary calcium, one cannot conclude that feeding frogs are in negative Ca2+ balance.
