How To Cultivate Lobster
Freshwater crayfish can usually survive on quite wide water parameters. LAT is also tolerant of low amounts of dissolved oxygen. However, to be able to grow properly in conditions like this is certainly quite difficult. In order to grow properly, LAT requires dissolved oxygen content above 4 ppm. In addition, freshwater lobsters are tolerant at very cold temperatures to temperatures above 35 ° C though. However, as a suggestion, LAT should be maintained at a temperature of about 25-29 ° C.
As for the water acidity level, freshwater lobsters can live in waters whose pH range is slightly alkaline ie between 7-9. Freshwater lobsters are rarely found live in waters with a pH below 7. For the lime content required for live mediums the LAT is moderate to high. This condition needs to be conditioned to keep the dissolved calcium level high so that it supports the formation of LAT shells.
Media live Freshwater Lobster
The medium that can be used for the cultivation of freshwater lobsters varies widely. Generally LAT is extensively farmed in ground pools. In extensive cultivation, lobster farmers only put the sires in the pond when the pond is drained. Lobsters whose size has reached commercial size then sold while the rest is returned to the ground pool. While in the process of intensive cultivation, farmers began to feed on lobster with a variety of vegetables including commercial feed. The results obtained using intensive cultivation can yield better results than extensive cultivation. In addition to the ground pool, other media for the cultivation of lobster is usually a pool of fiber / tank or cement pool. Swimming fiber and cement ponds are widely used in enlarging burayak. In Indonesia itself, freshwater crayfish cultivation is found on a home scale only, primarily in hatcheries.
Freshwater Lobster Breeding Process
Distinguish males and females
Prior to breeding lobster farmers should be able to know first the difference between male and female lobsters. How to distinguish genitals of the youngest is to use technical visual from above.Lobster males can be seen if the outer stamps contain red spots. However, the red marks appear only when the lobster is 3-4 months old or after the lobster is 3 inc (7 cm). This red sign is also a sign of a male lobster ready to mate (ripe gonad). While in the female lobster in the same part does not appear bulge (penis). The female lobster feature is a hole in the base of the third leg from the bottom (tail). The hole is the female lobster sex and the place to remove the egg.
Selection of freshwater lobsters
Select sizes that are over 4 inches (10 cm) in size or aged over 5-6 months because these lobsters will have a significant number of tillers.
Tips on choosing a qualified prospect;
a. Choose the fastest growing sores among the other lobsters
b. Buy a broodstock at a certified mall seller
c. Notice the genitals, do not select the lobster "effeminate". Because there are sires that have female sires, but also have male sex (often called a sissy lobster). The lobster is unlikely to lay eggs
d. Choose a fat lobster. Avoid choosing sires whose head is large but the body and tail are small. These characteristics indicate that the lobster is less eating.
e. Minimize the minimum lobster when it is 4 inches or approximately 5-6 months old. The smaller (young) the lobsters are mated, the growth of the puppies will always be slow. For example, if marrying a 3-inch (7.5 cm) and 4 inch (10 cm) lobster would be much faster than 3 inches. However,
does not mean the size of a 3-inch lobster breeder can not exceed its parent body. The lobster can still grow beyond its mother but the process is slower. A 3-inch lobster has a maximum of 50 eggs, while a 4-inch lobster can produce 200 eggs.
f. Qualified lobster breeders can be obtained by separating male and female lobsters when they are 2 inches (5 cm) in size. Best new mating after each
reach the minimum size
4 inches (10 cm).
g. It is also important to know the origin of lobsters or their families to select the pure lobster species of certain species in order to grow better lobster saplings
- Marry Lobsters
Combine the males and females of lobster into one in a medium aquarium size 1x 0.5 meters high 25 cm can be input about 5 female lobsters and 3 male lobster. One male principle is able to fertilize 30 females but in marriage in aquarium used 3 male lobsters because in the marriage the female lobster is more dominant in choosing the matching pair.
