FISH CULTURE

Black Ghost Black Ghost (Apteronotus albifrons) comes from South America region and are carnivorous. Original habitat temperature 25-28 ° C; pH 6,5-7,0; and hardness 6-10 ° dH. Her form was like a sheet of leaves or a knife with a plain black color and swim vibrate or slide. Fish is happy with the place was quite dark or dimly lit and will hide when there is a hole, especially in the afternoon. Therefore, in case maintenance is needed provided the hiding place of the roots of trees or paralon pieces. Between males and females difficult to distinguish. Back to the male line a little shorter than females. In addition, the tail fin is narrower in females than males. Spawning can be done in pairs or mass. Mass spawning with male female ratio 1: 2. However, because the size of the parent can be more than 20 tail then the container should be large enough. Cement pond approximately 1.5 cm x 2.0 m usually be used to memijahkan 20 tails. While the aquarium size 100 cm x 40 cm x 40 cm good enoug

topographic engineering requirements of fish ponds Technical aspects In addition to the six socio-economic conditions mentioned above, technical requirements are also important to note. Requirements of this technique include topography, soil, and water. 1. Topography Topography is the overall shape of the land surface (flat, undulating or steep). Topography is our spotlight for the first time will determine the type, area, number, and the depth of the pond which will be made. Sloping land once, can not be built units will form the pool for a small pond and the embankment will be wide. This broad embankment works to hold a large mass of water collected underneath. Similarly, if the soil is too flat, it will cost to dig a big land. It also would complicate disposal of water (drainage). There are six types of places that have character and a special utility for making the pond, which is V-shaped valleys and essentially flat valley ' a. V-shaped valley sharp Do not ever make a fish pon

Pests and disease prevention in fish Catfish Sangkuriang Just like other fish, catfish sangkuriang not be separated from the threat of pests and diseases. Disease affecting sangkuriang catfish most often caused by environmental conditions that are less supportive, such as water quality (especially temperature) under standard or stress due to the fault handling sick fish. Meanwhile, the usual pests attacking sangkuriang catfish include snakes and eels, while organisms that attack pathogenic form Ichthiophthirius sp., Trichodina sp., Monogenea sp., And Dactylogyrus sp. Poverty entry of pests of seedlings can be done by providing a recommended insecticide when filling the pond water, clean the pond dikes, and put plastic around the pool. Pathogenic organisms prevention can be done with the cultivation of environmental management is good and a regular feeding and inadequate. Treatment can use drugs recommended. environmental management can be done by doing a good pond preparation. If you n

The history and origins of tilapia fish in Indonesia Nila fish was first imported from Taiwan to Bogor (Center Fresh Water Fisheries Research) in 1969. A year later, these fish begin to cast to some areas. Indigo naming provisions under the Director General of Fisheries in 1972. The name is taken from this fish species narna, namely nilotica which is then converted into. Name nilotica showed these fish homelands, namely the river These fish are naturally migrating from its original habitat in the river Nile in Uganda (the upper reaches of the Nile) to the south past kw Raft and Lake Tanganyika to Egypt (along the River Nile). Nila also found in Africa, central and western parts. Largest population is found in fish ponds in Chad and Nigeria. With human intervention, today tilapia has spread around the world starting from the continent of Africa, America, Europe, Asia, and Australia. Classification Initially, indigo included in Tilapia nilotica species or tilapia fish from groups that do

Prawns Prawns (Macrobranchium rosenbergii), including one of the leading commodity fisheries freshwater cultivation of high economic value, but has not developed to its optimum. Currently, besides local prawns are usually cultivated farmers, high yielding varieties also known as prawns gimacro (genetic improvement of macrobranchium rosenbergii) with a faster growth rate and form karapasnya smaller than the size of local prawns karapas that contain meat more. At the age of five months, the body length of male prawns gimacro reach 38 cm in body weight reached 480 grams per fish. Meanwhile, in the same period, the length of the body of local prawns reaching only 25-28 cm in body weight of only 200 grams per fish. In fact, the maximum size of local prawns ever found in the wild only 300 grams per tail. That's why gimacro prawns prawns known as super because pertumbuhanya very quickly. prawns added value options when maintenance is relatively brief, lasting from 3 to 5 months. Productio

FISH NILEM Fish Nilem (Osteochilus hasselti) many maintained mainly by farmers in Sumatra (West Sumatra in particular) and in the region of West Java Priangan). In its original habitat, these fish are found living wild in public waters, especially in rivers that have current and water was clear. It also can be found living in a swamp. Nilem known for having a sense of meat and eggs is very tasty. In the area of Sumatra, this fish is often cooked by baking or following dipangek eggs.

Catfish fish morphology. catfish fish is one type of fish from catfish groups. The length of adult catfish reached 120 cm. This body size is a measure of body belonging to the fish catfish species. Elongated shape with a dominant color such as silver glittery white on the back and bluish. Body color silvery glow very bright as a child, so many people who keep the aquarium as ornamental fish.

Her mouth is located at the lower end of the head. In the corner of his mouth are two pairs of whiskers that serves as a search tool feed and tentacle while swimming. At the back there are fins with a strong fingers that can turn into shaft. soft fingers fruit numbered 6-7. form symmetrical forked tail fin. In the pectoral fin is 12-13 fingers - fingers soft and one hard fingers that function as shaft. Anus fin length, consisting of 30-33

Living Conditions and Life Habits Patin very tolerant of acidity (pH) of water. This fish can survive in waters with a degree of acidity is slightly acidic (low pH) to the alkaline waters (high pH) with pH 5-9. Oxygen content (02) solute needed for the life of catfish are 3-6 ppm. Levels of carbon dioxide (CO2) that can ditoleran is 9-20 ppm. The required level of alkalinity 80-250 ppm. Meanwhile, the optimal water temperature for the growth of catfish is 28-30 ° C. In its original habitat, the fish is always hiding in holes. As fish nocturnal (active at night), a new catfish out of his hiding hole when it was getting dark. Other habits, this fish is more settled in the bottom-waters than appears on the surface of the water. Therefore, catfish is classified as basic water fish (demersal). This can be proved from the form of a broad mouth like the mouth of demersal fishes in general. Naturally, catfish feed in the wild form of small fish, worms, detritus (pengurai microbes in the bottom

SEPAT SIAM Snakeskin consists of several types, but the famous are only two kinds of sepat (Trichogaster trichopterus) long, 12 cm maksimuni his clan sepat siam (Trichogaster pectorahs) the maximum body length of 25 cm.
