In-feed medication as a cure against white spot disease in marine fish.

In marine set-ups, it is not always possible to add medication to the water to cure many of the fish diseases because it could adversely affect the invertebrates in the system (e.g. coral, shrimp, molluscs). In-feed medication would be the better way to proceed provided the fish are eating and that they are able to accept dry/manufactured food in which medication can be applied to.

So, it is advisable to try and train your fishes to accept dry foods in the event that a disease outbreak occurs.

This paper shows results from research into a possible treatment for marine white spot disease in fish.

	Abstract:	We investigated the effects of dietary Romet®30 (sulfadimethoxine–ormetoprim (SDMX–OMP)) on Cryptocaryon irritansinfection in red sea bream Pagrus majorand tiger puffer Takifugu rubripes. In Experiment I, 100% mortality of P. majordue to C. irritansinfection was observed at 10days and 21days after exposure to theronts (infective stage) in the a control group without Romet®30 and the group treated with 50mg Romet®30/kg body weight (BW)/day for 14days, respectively. Thus, mortality in the treated group was markedly delayed compared with that in the control group. In Experiment II, 100% mortality of P. majorin the control group due to C. irritansinfection was recorded at 11days after exposure to theronts. In contrast, mortality due to parasite infection was not observed in the group treated with Romet®30 at 50mg/kg BW/day for 14days, and no parasites were found in any surviving fish after 33days exposure. In addition, the number of parasites on the gills of T. rubripestreated with 50mg Romet®30/kg BW/day for 14days was significantly lower than that in the control group after 16days exposure. These results show that in-feed Romet®30 at 50mg/kg BW/day for 14days had antiparasitic and therapeutic effects against C. irritansin both P. majorand T. rubripes. Thus, dietary Romet®30 could be useful for controlling C. irritansinfection.
