FISH CULTURE

Worms In Fish Gills Cause: Haliotrema spp., Psedorhabdosynochus spp. Bio-Ecology Pathogens: • Ekto-parasites are obligate parasitic • infect the gills of fish mariculture. Two or possibly three species belong to the genus monogenea Pseudorhabdosynochus namely Pseudorhabdosynochus latesi. P. monosquamodiscusi, and Diplectanum penangi, while P. epinepheli found in groups of grouper. Clinical Symptoms: • pale body color, decreased appetite, lean, and slow • Respiratory frequency increased and the production of excess mucus in the gills • Gather / closer to the water inlet • Gills pale or swollen so that the open operculum Diagnosis: • Visual observation of behavior and clinical symptoms that arise • Microscopic observation to see morphology parasites through the production segment of the organ gill preparations. Control: • Reducing the levels of dissolved organic material and / or increase the frequency of water changes • worm attacked fish gill with the level and intensity of the low pre...

Dactylogyriasis (Worms Gills) Cause: Dactylogyrus spp., Cychlidogyrus spp., Quadricanthus spp. Bio-Ecology Pathogens • Ekto-obligate parasites that are parasitic and reproduce by laying eggs • infect all species of freshwater fish, especially the size of the seed.
