Seahorse nursery has been formed in the hatchery aquatrop, but there are many
death of seahorses in the hatchery caused by pathogens. So a study has been
conducted to isolate and identified this microbe from water in the reservoir before the
filtration process and water that supply to the tank containing seahorses after filtration
process. The both water sample were serially diluted by tenfold and four organisms
has been identified. The result for water sample before filtration is only on 10 −1 plate
where the fungus grow filamentous form while the result for water sample after
filtration is on three plate which are 10 −2 , 10 −4 , and 10 −8 . The fungus grow circular
form on 10 −2 plate while on the 10 −4 plate, the fungus grow irregular form and on
the 10 −8 plate the fungus grow filamentous form but it black in colour. So from the
result, we can say the filtration system is not effective enough to prevent further
fungus infection but the suggestion is to sterilize the water from reservoir before it
enter the first filtration system. So by doing that probably the water quality will be
better and can prevent further infection by pathogen fungus.
