Maintenance of fish larvae Gurame the maintenance activities of carp larvae things to note are: - Container maintenance - Water quality - Feed - Maintenance / handling Container Maintenance carp larvae of container from the egg is usually placed in the aquarium, but the hatching eggs can also be done in the bucket. for the aquarium with a size of 80 x 40 x 40 cm the number of eggs that can accommodate about 2,000 eggs. water level for maintenance of the eggs in the aquarium 15 cm, the container should also be installed aerator maintenance, heater. functioning aerator to supply oxygen to the aquarium water. This aerator works to increase the oxygen content. oxygen needed by fish to help increase fish growth. fish metabolic processes require oxygen in the growth stage, when the oxygen content in the aquarium is less it will affect the lives of fish so that fish growth is less than optimal. Heater / water heater Different types of heater there is a 50 watt, 7...

Betta   fish   can   prevent   dengue fever Dengue fever   caused   by   mosquitoes ,   can be   prevented by   way   betta   fish   betta   fish   is available   in   bottles   we input   into the tub . in the bath   betta   fish   will eat   mosquito larva .   then   after   2-3   days   betta   fish   is removed and inserted   back   into the bottle .   then   inserted   back   into the bathtub   and so on . this is an   effective way   to   combat   /   prevent   dengue fever .   when compared   with the fumigation   may only   kill the   mosquitoes   alone but   eggs   and   larvae   of mosquitoes   in   the water   does not   come   off

VISUAL CHARACTERISTICS OF FISHERY PRODUCTS CONTAINING SUBSTANCE DYES The use of dyes as additives in foods aimed at giving the impression of attractive , uniform color and improve fishing . Dyes there are 3 ( three ), namely : natural dyes, which is identical with natural dyes and synthetic dyes . Dyes commonly used in fishery products are synthetic dyes such as Rhodamin B , Wantex , ponceau 3 R and c mettanyl yellow which actually used to dye textiles and paints . These dyes are not allowed for human consumption ( No. Permenkes . 239 of 1985 ) because they contain heavy metals and are thought to cause cancer . The dye is banned : Rhodamin B , c methanyl yellow , orange RN , erythrosine , tatrazine , yellow FCF , Brilliant Blue , Ponceau 4 R , etc. . The dye is allowed: Auromino etc. . Dye substances on health effects : When consuming products containing banned dye which can lead to: - Bladder...

requirements in the cultivation of freshwater fish In cultivating fish in the pool or pond there are some requirements that need to be known, including among others : 1. Water Sources In the selection of places to fish farming need to pay attention to water resources . These water sources must be sufficient and adequate . These water sources can come from rivers , irrigation flow , as well as springs. water source available throughout the year as far as possible with adequate discharge . one example in a goldfish requires a water supply with a debit 10-16 liters / sec / ha . 2. Soil type and slope in building a pool should pay attention to soil type and slope . ponds are built should have a clay type of soil or sandy loam (sandy clay ) so it is not porous . The slope of the land used for fish culture should have a slope of 50-10 degrees and water conditions will thus facilitate the drainage of wat...

Shrimp Disease: Disease Yellowhead Cause: Yellow Head Virus (YHD), corona-like RNA virus (genus Okavirus, family Ronaviridae and the order Nidovirales) Bio - Ecology of Pathogens: • Krustase sensitive to infection with this virus include: Penaeus monodon, P. merguensis, P. semisulcatus, Metapenaeus ensis, Litopenaeus vannamei, etc.. • Shrimp black tiger shrimp is a very sensitive species, in acute cases can result in the death of up to 100% within 3.5 days since the first clinical symptoms appear. • Transmission occurs horizontally through the water shrimp or cannibalism to feed a sick or infected. • Post larvae (PL) shrimp aged <15 days relative resisters against infection with this virus compared with 20-25 days old PL or juveniles. • The molecular (DNA sequencing) from products of reverse-transcription polymerase chain reaction (RT-PCR) of yellow head virus have similarities to the gill-associated virus (Gav), although different species or strains. Clinical Sympto...
