The growth and development of the Animal Husbandry Cultivation of freshwater crayfish (Applied) From category Crayfish, Fish, Lobster Below : Product Details : Cultivation of freshwater crayfish (Applied)Cultivation of freshwater crayfish [Budidaya lobster air tawar] (Cherax sp.) Began developing since 2000. These animals can spawn naturally or artificially spawning do not need. Therefore, this culture developed rapidly, and currently has stood center cultivation in some provinces, such as Jakarta, West Java, Yogyakarta and East Java.
Maintenance of the parent
Performed in a tank holding Pemaliharaan fiber or concrete tank. How, to prepare the fiber glass tanks or concrete tank measuring 2 m length, width and height of 1 m 1 m; dry for 3-5 days; water content as high as 30-35 cm; input in the form of pieces of pipe protector paralon 4 inches in diameter with a length of 15 - 20 cm; stem density of 10-15 ekor/m2 (males and females separately); news feed every day in the form of shrimp pellets with a diameter of 1 mm and 3 mm length of 2-4 eggs / tail; maintenance of the parent conducted during the 2-3 weeks and the water replaced every three days part ½.
Parent selection
Parent selection is done by observing the signs of the body. Sexually mature male parent which is characterized by genital pore is shaped like a small hose (petashma) located at the foot stalk fifth street, the carapace (head) is greater than the abdomen (body), the colors brighter than the immature parent or female parent.
While the female parent is characterized by genital pore (thelycum) as the hole between second and third legs roads, smaller carapace from the abdomen and the body color is more dull ari same male parent or male parent who was not yet ripe. In general, body size and claw males larger than females.
Spawning
Spawning is done in a basin or tub fiber concrete. How, to prepare the fiber glass tanks or concrete tank measuring 2 m length, width and height of 1 m 1 m; dry for 3-5 days; water content as high as 30-35 cm; input protection in the form of pieces of four inch diameter pipe paralon length 15 - 20 cm; stem density of 10-15 ekor/m2 dispersive five breeding females; dispersive three breeding males; give 2-4 butit shrimp pellets every day; (males and females separately); news feed every day in the form of pellets with a diameter of shrimp 1 mm and 3 mm length of 2-4 eggs / tail; maintenance of the parent conducted during 2-3 weeks and the water replaced every three days, part ½.
Spawning broodstock selection
Selection of the parent who has been prolific done by looking at the signs of the body. How, to dry the tub to a height of 6 cm; catch-parent female parent already contains eggs dark yellow or brown in color; input into the large basin is aerated; do re-selection to get a parent who truly mature gonad; input into the basin another. Note: do not win with sekup net, because it can cause the mother was shocked and the eggs fall. Catch with both hands, one to hold the head one more to hold the tail.
Incubation and hatching eggs
Egg incubation was conducted in an aquarium. The trick: prepare an aquarium size 60 cm length, a width of 40 cm and 40 cm high; dry during the two days; water content as high as 30 cm; pairs of two points and turn on aeration during incubation; input first breeding is already spawning; give 2 - 4 para shrimp pellets every day; replace part ½ setpa water once every three days.
Threshing eggs
Threshing eggs done after a period of incubation lasted for 40-42 days. How, surutkan water up to 20 cm, the parent with sekup catch net and lift up the aquarium, catch the parent by hand, dip the stem into the aquarium water repeatedly until the larvae in the body out; return home to the place of maintenance; aquarium water content was until it reaches the height of the original; leave for a week.
Larval rearing
Maintenance performed in a tank or tanks fiber concrete. How, to prepare the fiber glass tanks or concrete tank measuring 2 m length, width and height of 1 m 1 m; dry for 3-5 days; water content as high as 30-35 cm; input protection in the form of pieces of four inch diameter pipe paralon length 15 - 20 cm; capture larvae from the aquarium threshing, input into the basin; count; dispersive tail larva/m2 350; give 100 grams of flour pelet/1.000 ekoer larvae; do harvest a month later.
Separating I
Separating the first carried out in the pond soil. How: ready pool size 100 m2; dry 4-5 days; fix all the parts thereof; make kemalirnya; essentially averaged soil; scatter two sacks of chicken manure or quail; contents as high as 40 cm of water and soak for 5 days (the water is not discharged); dispersive 5000 larvae in the morning, after two days, give 0.5 to 1 meal pellets or pellets that have been soaked every day; harvested seeds after 3 weeks of age.
Germination II
Separating the two also performed at the earthen pond. How: ready pool size 100 m2; dry 4-5 days; fix all the parts thereof; make kemalirnya; essentially averaged soil; scatter two sacks of chicken manure or quail; contents as high as 40 cm of water and soak for 5 days (the water is not discharged); dispersive 3000 fry from the nursery I (already selected); give 1-2 kg of flour pellets or pellets that have been soaked every day; crop seeds after one month of age.
Separating III
Germination was conducted in three earthen pond. How: ready pool size 100 m2; dry 4-5 days; fix all the parts thereof; make kemalirnya; essentially averaged soil; scatter two sacks of chicken manure or quail; contents as high as 40 cm of water and soak for 5 days (the water is not discharged); dispersive 2000 tail results from separating II (already selected); give 3-5 kg of small pellets (especially shrimp); seed harvest done a month later.
Enlargement
Enlargement of freshwater crayfish in earthen pond done. The trick: prepare a pool size of 200 m2; fix all the parts; scatter four sacks of chicken manure or quail; water content as high as 40-60 cm and soak for 5 days; input selection in 6000 fry from nursery III; news feed 3 percent every day , 3 kg at the beginning of maintenance and be on the increase according to the weight of the fish; circulate water continuously; do harvested after three months. A pond can produce beukuran consumption of 20-30 grams of 80-100 kg.
