| prevalence of fish-borne trematodes of the family heterophyidae at pasak cholasid reservoir, thailand. | the prevalence of fish-borne trematodes was investigated in various species of freshwater fish at pasak cholasid reservoir in thailand. the samples were collected from fish markets around the reservoir between june 2011 and may 2012. a total of 789 fish samples were classified into 25 species. the metacercariae (i.e., the larval stage of trematodes) were examined from 4 parts of the fish body, and evaluated using the compression method. ten species from two families of the fish collected were fo ... | 2016 | 26796861 |
| hepatic 5'-monodeiodinase activity in teleosts in vitro: a survey of thirty-three species. | the in vitro hepatic 5'-monodeiodination of thyroxine (t4) to triiodothyronine (t3) in oreochromis mossambicus, channa striata, clarias batrachus, cyprinus carpio and oxyeleotris marmorata was found to be time, ph and temperature dependent, and related to the amount of substrate (t4) and homogenate introduced into the reaction vessel, in a manner which was consistent with menton-michaelis kinetics, and thus indicative of an enzyme-regulated process. dithiothreitol introduced into the reaction ve ... | 1990 | 24221892 |
| changes in sperm motility in response to osmolality/ca2+ in three indonesian fresh water teleosts: goby (oxyeleotris marmorata), java carp (puntius javanicus), and catfish (clarias batrachus). | sperm of most fresh water teleosts become motile when released into the hypotonic fresh water environment, but the role of osmolality and ca2+ on sperm motility is not clear. osmotic pressure and ca2+ concentrations increase from fresh water to brackish water. java carp puntius javanicus and catfish clarias batrachus live and reproduce only in fresh water. on the other hand, goby oxyeleotris marmorata can acclimate and reproduce from fresh water to brackish water. in the present study, sperm mot ... | 2006 | 16458554 |
