1ways to raise freshwater crayfish 01 Tips on How Lobster Hatchery Freshwater Aquaculture

Nurseries lobsters in 15 cement pond beside the house with a pool size of 2×1 m2, m2 2×2, and 2×3 m2. required to perform is the mother of quality nursery.

Hatchery Process

Seeding can be done in the aquarium (size 100x50x25cm) contains 1 set of breeding lobsters or cement pool (2x1m size) containing 5 sets of parent lobster. More and more number of sets of broodstock lobsters are placed in one pool will be better because of the nature of female lobsters are highly selective in choosing a stud. That is, if in a pond there are many males, the likelihood of marriage is also getting bigger. The characteristics of a good female parent is the head size is smaller than the size of his body. Sebailiknya better stud whose head bigger than his body.

Over the past 2-3 weeks there will be marriage breeding process. The signs of nesting female parent is the tail curved up to the first leg. Having seen the signs of spawning, the female parent move to another aquarium. Try an aquarium (size 100x50x25cm) contained 1 female parent with a size 20-25cm of water. this is to avoid a fight between a female lobster that can result in loss of eggs.

One parent lobster female lobster can produce 200-300 eggs. Lobster egg incubation process takes 30-35 days. For the lobster hatchery, takes 3-4 days. After the eggs hatch, immediately take the parent. If the parent is not taken more than a week, the parent would prey on his own.

After the mother separated from her child, separate the parent of other adult lobsters. For the next mating, the female lobster should wait at least 2 weeks or until the skin changed. 2 weeks is a break for the lobster females after laying eggs. Parent biased freshwater crayfish live to be 3-4 years with 20-25cm long and weighing nearly 0.5 kg. at that age, more and more lobster will produce eggs, even a bias in number in the thousands. “The older the lobster, then the number of eggs will be more and more., Because of his too big, strong, and long.

Seed Maintenance

After the eggs hatch into seed, a month later separated, the seeds are large, medium and small. Once sorted, separate seeds based on their size lobsters are then moved from the aquarium into the cement pond. Cement pond is better for seeding because of the rise and fall temperatures in the cement pond is not too drastic or bias temperature is maintained when compared to the aquarium. Temperature suitable for freshwater lobster seed is 25-300C.

For additional air, give aerator medium size (8 points air) in the cement pond (size 2x1m). After 2 months, good development of seed lobsters will be sized 2 “(5cm) and ready for sale. The length of time the overall hatchery business about 6 months of starting the process of mating sires until the seed reaches the age of 2 months. The risk of death during maintenance of seed is about 20%.

Food that is suitable for seed lobster is a lobster special pellets, vegetables (eg bean sprouts and carrots), and fresh proteins (eg silk worms and the worms freeze). For more recommended seeding fed with worms because of higher protein levels. For vegetables, before feeding on seeds must be soaked first lobster without chopped or cut.

Lobster is the type of animals that live in the bottom of the pool, so all food must be at the bottom of the pond. If food is floating, the lobster will not eat it. In one day, seed lobsters were fed 2x, ie in the morning (7:00 to 09:00 am) and afternoon (17:00 to 20:00 o’clock). ideal for breakfast servings 1 whole lobster is ¼ teaspoon of pellets and to eat as much as ½ teaspoon afternoon. For silk worms or frozen, usually 1 liter of worms can be spent within 1 week for 1000 seed lobsters.
The food in the form of worms, vegetables and pellets can be done alternately. Pellets are usually used Pokphand is a brand of pellets for high protein content, which is around 30%.

Seed Disease Prevention

The disease usually attacks the seeds are parasites that live lobsters in the head and body of the lobster. Parasites are white milk and breed bias in the body and head of the lobster. Feature lobster parasite is affected by reduced appetite and not agile so that the bias resulted in death.

To cope with this disease, usually soak the seeds are exposed to the disease lobster in salt water with salinity 30 ppt (salinity units). Soak seeds in water lobsters for 10-14 days and once every 3-4 days replace the water with new salt water. When soaked, usually seed lobster will jump up and down and that’s when parasite eggs will die.

That must be considered in hatchery lobsters are feeding and water quality. Usually change the water once a month, however, the substitution bias water faster or longer than necessary. This depends on the level of impurities in the water. If the leftover dirt levels greater than the levels of dirt from the seeds of its own lobster, then the water will be poisonous. Traits that have been poisoned water is the color of water turned into a murky and smells bad. The toxin produced from the rotting food scraps in the water. Therefore keep your food is always out for a meal so as not to leave the rest in the water.

Packaging (packing)

Lobster seed to be sent to consumers is usually packed in a Styrofoam container that can contain measuring 40x30cm 1000 larvae of lobster size 2 “(5cm). to resemble lobster seed to be sent, first of all the contents of styrofoam with a bottle of ice cubes placed at the bottom of the container and then wrapped in newspaper. This is to avoid melt the ice so as not exposed directly to the seed because if it is too cold lobster, lobster seed will die. Then place the lobster on top seed and give the form of foam insulation that has been squeezed wet thin and arrange the other above the seed lobster foam up to 5 layers.

Fire Lobster

Freshwater Lobster: Opportunities breeding and rearing of freshwater crayfish are very prospective and promising. Imagine, reviewed the cultivation methods that are not too hard and paid-in capital was not too big. We can start a home-based scale for the nursery to capitalize aquarium, while for the enlargement can be done on the cement pond, fiber, or pond ground.

For those who do not have land too large, the enlargement can be done by using a pool tarp whose walls are made of wood. even we can use the gutter as a container for breeding!
