Tilapia simply spawn naturally. Even these fish ar simply spawned wildly in cultivation ponds. not like Carassius auratus or catfish that need heaps of engineering. Settings ar solely required to manage in order that spawning is in restraint.

With correct management, fish genus property can become a profitable business. On this occasion, it’ll be mentioned what must be ready to begin fish genus property.

Tilapia property

The first factor that has to be ready in fish genus property is that the preparation of an area or lake. There ar four forms of ponds required for fish genus property, including:

Maintaining ponds.

This pool is employed to keep up male and feminine broodstock. Male and feminine fish should be placed in several ponds. in order that it takes a minimum of 2 main maintenance ponds. The lake doesn’t got to be overlarge, solely the water should be deep enough for adult fish, around 100-140 cm.

Spawning ponds.

Spawning ponds ar accustomed mate male and feminine oldsters. the sort of fish genus spawning lake construction ought to get on the bottom floor. the lowest of the pool is supplied with a puddle or kemalir.

lake maintenance larvae.

This pool is required to keep up freshly hatched fish larvae. the sort of pool used may be sort of a cement, lake or hapa. Hapa could be a soft internet sort of a screen that’s created to float on a lake. specifically sort of a floating internet in a very lake, however little in size. however are you able to place it in a very spawning pool.

sper-matophyte ponds.

This lake is required to boost fish seeds up to 10-12 cm in size. Or, till a robust fish genus to be raised in associate cultivation lake.

Selection of fish genus broodstock

Prospective broodstock for property fish genus ought to use pure strains that ar genetically superior. nowadays fish genus brooders current within the community many that have tough a decline in quality. to urge a superior broodstock, you must look in trustworthy places like, BBPBAT or native fishing halls.

Brood fish genus broodstock or able to spawn, the worth is sort of costly. For this reason, {we can|we will|we ar able to} keep prospective broodstock from childhood till the fish are able to be breeded. The characteristics of a decent prospective indigo parent ar as follows:

Is a pure strain and comes from completely different breeds.
His condition is healthy and his body form is traditional (not deformed).
Large scales, neat arrangement.
The head is comparatively little compared to the body.
Thick body and glossy color.
Its movements ar agile, alert to feeding.
Female fish genus enters mature gonads once 5-6 months older. the feminine parent to be breeded has a minimum of reached a weight of 200-250 grams and for begetter 250-300 grams.

As mentioned before, fish genus could be a little variety of eggs. One parent advisement 200-250 grams contains solely 500-1000 eggs. Of this quantity, the hatching into larvae sometimes ranges from 200-400 tails.

The productivity amount of broodstock for fish genus property ranges from one.5 to two years. Parent that has been hatched for quite two years ought to get replaced with a brand new one. as a result of the standard and amount of puppies can decrease. Parent fish genus that are spawned ar able to be spawned once more once 3-6 weeks.

Maintaining broodstock

Male and feminine broodstock ready for fish genus property should be unbroken in separate ponds. parent united with different females, moreover as begetter. Stocking density for main pool is around 3-5 birds / money supply.

Mains maintenance ponds male and feminine should have a unique supply of irrigation (arranged in series). sewer water from the male pool doesn’t enter the feminine pool and contrariwise. this is often to avoid spawning. for instance, male sperm cell ar carried to the feminine pool therefore fertilization happens.

Feeding for prospective broodstock ought to have high macromolecule content, quite thirty fifth. In distinction to fish genus feed for enlargement that solely needs concerning two macromolecule content. High macromolecule content is required for optimum endocrine growth. the number of feed required for raising broodstock is third-dimensional of fish weight per day.

Tilapia spawning

As antecedently delineate, fish genus is extremely straightforward to spawn naturally. Intensive fish genus spawning is sometimes accustomed turn out massive amounts of seed. as a result of to create infrastructure needs massive capital. this point we’ll solely review fish genus spawning naturally.

The bottom of the fish genus spawning lake ought to be leaning around 2-5%. Then build kemalir or puddle at the lowest of the lake as deep as 20-30 cm as spawning fish locations.

Before you set it within the spawning lake, do the lake bottom process initial.

Tilapia spawning is finished in bulk. Male and feminine broodstock ar unfold into spawning ponds along. Stocking density of spawning ponds the maximum amount as one head / money supply, with a magnitude relation of male and feminine 1: three.

During the spawning method, offer food like in a very mother rearing lake. fish genus spawning can sometimes surface on the seventh day since the broodstock is furnished .

Spawning takes place at the lowest of a lake, sometimes in a very puddle or basin. If there’s a match, the eggs issued by the feminine parent are going to be fertilised by male fish. Then the eggs ar incubated within the mouth of the feminine parent.

During the egg incubation method, the feminine parent sometimes fasts. Then, it’s higher to cut back the feeding till it’s solely 0.5 as little. this is often necessary to cut back production prices and forestall the buildup of leftovers within the bottom of the lake.

The incubation method sometimes lasts concerning one week. The eggs can cook into fish larvae. If the feminine parent feels the lake is overgrown with natural fish food, she is going to take away the larvae from her mouth at the same time. Therefore, within the lake preparation method it’s necessary to fertilize the lowest of the lake in order that the natural feed of fish grows.

The freshly hatched fish larvae can swim to the sting of the lake. at once take with a fine sieve and transfer to fauna rearing.

Larval rearing

Tilapia larvae that have hatched, ought to be raised in a very special place. Transplants ar meted out once the larvae ar 5-7 days previous.

Larva rearing lakes may be pond walls, aquariums, plastic containers or hapa. Stocking density for maintenance of 50-200 larvae / money supply, betting on the sort of lake.

Give high macromolecule feed the shape of fine flour mensuration zero.2-0.5 mm. The frequency of feeding 4-5 times every day, when the maximum amount as one teaspoon of flour-shaped feed.

Alternatively, fish genus larvae feed may be created by boiling a chicken egg. Then take the fixings, then mash and blend with 1/2 litre of water. Enter in a very spray bottle and provides to the fish the maximum amount as a hundred mil, when giving.

The larval nursery length ranges from 3-4 weeks, or till fish larvae live 2-3 cm. Larvae that have reached this size should be at once moved to consequent nursery lake. as a result of the capability of larval ponds is not any longer possible for such an oversized fish.

In the larval nursery stage, fish genus property may be created to provide fish seeds that ar all male sex. Enlargement farmers like male fish genus seeds to be raised, or fish genus cultivation by monosex. as a result of the expansion of male fish is quicker than feminine fish.

Breeding seeds

After the larvae ar raised to 2-3 cm in size, then do the nursery to urge fish seeds that ar able to be cultivated at the rearing place. Nursery ought to use a wider pool.

Stocking density for seeding 30-50 tails / money supply. the upkeep time for fish genus seeds at this stage is around 1-1.5 months. Or, concerning 10-12 cm in seed size.

Feed for nursery victimisation pellets with 20-30% macromolecule content. the number of feed required is third-dimensional of the weight of the fish. Frequency of administration 2-3 times every day.

But it doesn’t rule out the scale of the seed the market desires is larger than that. If so, perform the nursery stage two to the scale of the seed in accordance with market demand.

Furthermore, the results of fish genus property ar able to be raised in fish genus rearing ponds.

Harvest fish genus property

Another factor that has to be thought of in fish genus property is blighter and malady management. during this case bar efforts take precedence over treatment. as a result of the treatment of fish that are sick enough to consume resources.

Harvesting ought to be worn out the morning or evening. Packaging or transportation of seeds to be sold-out will use closed or open containers. For close-up shipping open containers ar still potential.

However, if shipping takes an extended time and also the distance is way, it’s suggested to use a closed instrumentality. Delivery in a very closed instrumentality needs aeration to complement the chemical element content of the water. The instrumentality is full of water till solely 1/3 of it, the remainder is chemical element.
