FISH CULTURE

Streptococciasis Disease Cause: Streptococcus agalactiae, S. iniae, Bio - Ecology of pathogens: • gram-positive bacteria, small round (cocci), joined chain-like, non-motile, transparent and smooth colonies. • Streptococcus iniae Infection often occurs in sea water fish farming (snapper, grouper), whereas S. agalactiae is more commonly found in freshwater fish farming (tilapia). • The pattern of attacks are generally two types of bacteria are chronic - acute. • Target organs of infection of Streptococcus spp. commonly found in the brain and eyes. so-called "syndrome, meningoencephalitis and panophthalmitis". The disease is frequently reported in intensive aquaculture systems, aquatic environment calm (stagnant) and / or recirculation systems, • Cumulatively, the attack of this disease can cause mortality of 30-100% of the total population during the maintenance period: and this disease is a potential obstacle that must be anticipated with respect to intensification and i...

Columnaris Disease Cause: Flavobacterium columnare or Fexibacterium columnare Bio-Ecology of pathogens: • Bacteria gram negative, small rod-shaped, movable slide, and there in freshwater ecosystems. • The nature of these bacteria are grouped to form a collection such as the column. • The attacks often occur in groups of fish after transportation. • The nature of the attacks are generally sub-acute - acute, when the dominant gill as a target organ, the fish will suffocate and the resulting deaths could reach 100%. Clinical symptoms: • sores around the mouth, head, body or fins. Brownish white sores then develop into ulcers. • infection around the mouth, looks like the lining of yarn (thread-like) so it is often called the disease "mouth fungus". • All around the wound is covered by the bright yellow pigment. • If the infected gills, damage starts from the tip of the gill filaments and spread to the base, filaments eventually rot and fall out (gill rot). Diagnosis: • Observatio...

Fish Cultivation in Confined Land With the new method, carp can now be grown in a narrow area, such as in the yard or the corner, home. The notion that the cultivation of carp to be done in the vast wetland is now living myth. Today carp can be cultivated in any location, whether in rural or urban, in the pool tarp, plastic or tub. That way, carp can be an alternative to people who want to earn extra income on the land around their homes. Fisheries Society Archipelago (PERMINA) Cultivation Training will hold a carp on a narrow land-based Guba biotic System Based Probiotic on Sunday, March 6, 2011 in Kampung carp Jambida, Bantul. Yogyakarta, With a practical resource, Kalimantan, Java carp tissue holder, carp farmers, and agribusiness consultant. Besides the introduction to the basics of carp cultivation correctly, in Gubug PERMINA Training is focused on direct practice in the pool, good pond, nesting, breeding and rearing, so they can run interactive and applicable. Training is open to...

Isopodiasis (fish disease) Cause: Nerocilla orbiguyi, Alitropus typus, etc.. Bio-Ecology Pathogens: • Isopod which is a blood-eating parasites 'blood feeder' relatively large size (10-50 mm), and its body consists of several segments that are equipped with a pair of eyes. • infected at all stages of fish and most fish are susceptible to parasitic infections, especially in the fish scales. • Sticking to the body surface of fish, in the mouth, nostrils or gill cover. • Transmission occurs horizontally, and the trigger between because of water conditions and high density. Clinical Symptoms: • Wounds and bleeding at the site of the bite, and this looks visually parasites attached to the body of the fish, especially under the scales or on the base of the fin. • Loss of balance, weakness, and decreased appetite. • Nekrosa the gill or skin tissue of fish. • slow-growing fish, often resulting in death due to anemia or due to secondary infection by bacteria. Diagnosis: • Visually looks ...

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...

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. Transmission occurs when infective face (Onchomiracidium). • Dactylogyrus spp. has 2 pairs of eye point, and at the tip of his head there are 4 bumps. Cychlidogyrus spp. shape is more flattened at both ends, and only has a pair of eye point. Quadricanthus spp. shape Dactylogyrus similar spp., and has a host of species that target specific groups of catfish. • Severe infections can kill 30-100% within a few weeks Clinical Symptoms: • pale body color, decreased appetite, thin, nervous and slow • Respiratory frequency increased, the production of excess mucus in the gills and often cavort • Gather / closer to the water inlet • Gills pale or swollen so that the open operculum Diagnosis: • Visual observation of behavior and clinic...
