Silk worms. Silk worms has the Latin name Tubifex sp. in Indonesia silk worms known as hair worms or blood worms are small worm-sized reddish hair with a length of about 1-3 cm, with brownish red body with segments. One feed is needed for cultivation is natural feed. There are a wide variety of natural food to the attention of akuakulturis, such as phytoplankton, zooplankton, worms, and maggot.
Biology and Morphology Sutra worm (Tubifex sp)
Silk worm or hair worms belong to the group of worm-worm (Tubifex sp). In the taxonomy of animals, silk worms are classified into groups of nematodes. Silk frills given because this worm has a body that is soft and very soft as well as silk. Meanwhile nickname given because the hair worm long body shape and very smooth no difference as hair.
Silk worms (Tubifex sp) can be classified as follows:
- Phylum: annelid
- Class: Oligochaeta
- Order: Haplotaxida
- Family: Tubificidae
- Genus: Tubifex
- Species: Tubifex sp
Silk worms (Tubifex sp) did not have gills and body shape were small and thin. Because of the small and thin body shape, the exchange of oxygen and carbon dioxide are common on the surface of the body that contain many blood vessels. Most Tubifex make tubes in the mud at the bottom, in which part of his body protruding posterior end of the tube moves back and forth while waving actively in the water, resulting in water circulation and worms will get oxygen through the body surface. Vibrations in the posterior part of the body of Tubifex can help respiratory function
Terms Life Sutra worm
This worm has a shape and size that is small and slim with a length of 1-2 cm, at first glance looks like a colony of red waving as her reddish color, so it is often also called hair worms. Live silk worms fresh waters are clear and slightly flowing. Preferred basic water is muddy and contains organic matter. The main foods are organic parts have decomposed and settles in the bottom waters (Djarijah 1996).
Reproduce by laying eggs, nesting process occurs inside the cocoon is an oval-shaped segments consisting of kelenjaar epidermis of one segment of the body. After a few days the embryo of this worm will come out of the cocoon. The silk worm began to proliferate after 7-11 days
An easy way cultivation of silk worms
Parent cocoon that can produce and secrete eggs hatch into tubifex have around 40-45 days of age. The time needed for the process of breeding eggs inside the cocoon until the embryo hatches into tubifex takes about 10-12 days. Benefits of silk worms
Hair worm is one of the natural food alternatives that can be selected to feed the fish you keep, especially during the larval stage until the seeds or for your ornamental fish because it contains good nutrition and tend to be balanced and very good for the growth of fish.
SILK WORM FARMING (Tubifex sp) TRAY WITH MEDIA
One among many natural food is the silk worms are also known as hair worms. Silk worm is a favorite for all seed eating fish that can be natural feed. It also can endure a long life in the water and nutritional value there is on this worm is quite good for the growth of fish. The development of natural feed silk worms still quite traditional.
Cultivation With Tray / Tray Plastic
Cultivation of silk worms with Tray / Tray new count is done. Cropping systems using these trays recently discovered some time ago by a silk worm farmers, Mr. Agus Tiyoso.
Silk worm cultivation Media Tray
This system is basically treating and reusing water that has been used in the process of shrimp farming. On systems using a silk worm cultivation trays / tray has several advantages, namely:
Water that has passed through the arrangement of media in the tray / tray accommodated with a container at the bottom of the rack and then channeled back to the top of the media by using a water pump / dab.
Probiotics and drugs mixed in growth media / substrate cultivation of silk worms are carried on the flow of water is not wasted by useless to the outer waters. Cultivation of silk worms with this system does not need large area, because the media are arranged vertically upward secar dilahan also tend to narrow as the sidelines Blocking home or elsewhere.
Silk worm cultivation From Waste Swimming Lele
There is one unique and interesting ways in the cultivation of silk worms is to utilize organic waste from pond catfish consumption.
He has successfully cultivated silk worms from organic waste catfish pet. Worms that there continue to be maintained and cultivated until today.
Organic sludge from waste Swimming catfish can also for silk worm cultivation media with Tray
1. Preparation Swimming For Raising silk worms
Swimming less productive (not used for catfish farming) in the area of business of enlarging catfish may be intended for the cultivation of silk worms with an area of 60-100 m2 (adjusted to the existing area). Wastewater pond catfish enlargement stirred henceforth be included with the pump (with siphon) to pool the cultivation of silk worms.
2. Precipitation Air
3. Treatment Silk Worm
During the maintenance period the silk worms, try to keep the water in a small stream with water at a height of 5-10 cm. After 10 days the seedlings are usually silk worms begin to grow smooth and evenly across the surface of the mud in the pond. Repeat the process of adding waste water harvesting catfish into the pond cultivation of silk worms then after 2-3 months the worms began to be harvested.
Eating habits weft and silk worms (Tubifex sp)
Oligochaeta aquatic food consists mostly of berfilament algae, diatoms and detritus of various plants and animals. Most Oligochaeta obtain food by filtering substrates such as worms other habits. Organic components on a substrate ingested through the digestive tract. This worm obtain food at a depth of 2-3 cm from the surface of the substrate. Foraging silk worms its way into the sediments, a few centimeters below the surface of the sediment and choose food that is small and mushy.
The amount of food consumed daily by silk worms (Tubifex sp) is 2-8 times the body weight. The worms eat the thin layer just below the surface at a depth of 2cm-5cm. Also explained that in the lining of the many food substances that accumulate as a result of anaerobic decomposition.
Besides food, the population growth of silk worms are also determined by other factors such as the space (place) and the environment. Tubificidae obtain food at a depth of 2-3 cm from the surface of the substrate
Silk Worm Harvest Process
Silk worms will grow after 2 weeks prickly silk worms stocked or> 2 months if no stocking prickly silk worms. The first harvest can be done after the worms aged> 75 days. Characteristic pond cultivation of silk worms that are ready to harvest is when the mud as maintenance media was strong when held.
The worms are raised still mixed with mud, then put it in a bucket / tub containing water at a height of approximately 1 (one) cm above the media mud. The worm entered in Pemberokan bath for 10-12 hours. Worms ready to give to the fish fry or sold.
