FISH CULTURE

Argulosis (fish disease) Cause: Argulus sp. Bio-Ecology Pathogens: • The parasite is known as "fish lice" and sucking blood, is flat. and more looks like a plate. • Hurt fish body with the help of cytolytic enzymes, in addition to the skin, ticks are also frequently found in fish gills under the cap. • Almost all freshwater fish species susceptible to this parasite infection. • In high-intensity attacks. Adult fish can suffer death from lack of blood. Clinical Symptoms: • Visually it looks like a flea parasites that attach to the body of the fish. accompanied by bleeding around the bite. • skin irritation, loss of balance, swimming in a zig-zag, jump into the water and rubbed his body on hard objects around him. Diagnosis: • Visually looks a parasite that attach to the fish body Control: • Draining of the pond, followed by calcification. • Soaking can be done by: ✓ Dylox solution at doses of 0.25 ppm for 24 hours or more in the pool. ✓ solution of Ammonium chloride (NH4CI) at

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
