The Nile crocodile is a social species that nests in the community. In modern facilities, females can be raise from neonates to reproductive size.

When they measure between 1.8 to 2 meters in length in a period of six years. But generally, they do not achieve great hatching rates in their eggs, nor the high quality of their neonates, before the age of eight.

Wild females rarely nest before 2.7 meters in length. This means the age of 30 years, although the age-size relationship is specific for each population.

Advantages of Nile crocodile farming:

An advantage of captive breeding is the reduction of the age of nesting in the breeding stock raised in a hatchery.

The males mate with the females of the same age, but these unions usually do not have great success.

It is more usual to keep females with larger and older males. Animals captured from the wild and those that grow in breeding sites have marked differences in their ability to tolerate other adults.

Just as they differ in how much they reproduce efficiently in different conditions of confinement.

Wild animals are tame and accept human presence, but they do it faster if they remain isolated and without discomfort.

Females captured from the wild respond well under captive conditions that simulate their natural habitat.

Natural hábitat:

The natural habitat is wells with shallow and deep sites and reasonably stable water level, they should never be empty.

Because of the Nile crocodiles nest in holes. They usually look for nesting areas 1 meter above the water level. So banks should be made 2 meters above the water level.

These should be close to the shade and facing west so that they receive the afternoon sun.

The animals raised on farms have less rigorous requirements. And they will produce eggs in shallow concrete enclosures that are draine and clean regularly.

But even they will be more productive if the water depth is more constant. And if they are provided with appropriate nesting areas.

Reproduction systems:

There are two large production systems in Nile crocodile farms. The first is to keep a few females in a small enclosure with a male which is the most common.

The second is to maintain up to 300 females with multiple males, up to 60, in lagoons of several hectares in size.

It is not possible to compare the density and the mating rate and relate the efficiency of these two systems. Precisely because there are no system data in which multiple males are uses.

However, some general observations can be made. The biggest advantage of the multiple male systems is that the presence of an infertile male would not affect the annual harvest.

On the other hand, its disadvantage is that there are great problems among males due to their territorial conflicts when introduced into the enclosure.

There is a great possibility that only some males are related to mating activities.

In addition, it is difficult to monitor and analyze the reproductive history of females in these large systems and the management of crocodiles at the individual level is virtually impossible.

In small enclosures, a male can be enough for 20 females. The most common is to use 6 to 10 females and 8 is recommended. The females can all be of similar size, while the male should be 20 to 40% larger than them.

Enclosures must be made to allow wild females to have 8 to 10 square meters of water surface for each one.

Space for hatcheries:

A simple rectangular pond will suffice, although a pond with an inner island will be preferred by them. The construction of the pond can be done on land and the safety fence is placed 5 or 6 meters from the water.

So the animals that build galleries do not escape. The most efficient enclosures in relation to their costs have been made by damming natural drainage lines.

It is expected that in small groups of broodstock, 90 to 100% of the female’s nest for 20 years and possibly more.

Individual management and control are easy with well design ponds and these can be a drain and fill quickly if individuals need to be removed.

The main disadvantage of this system is that the total production of a crop can be lost if a male is incompatible or infertile.

This occurs in approximately 10% of these groups, although the system allows rapid identification and replacement of this male. You may also like to read Crocodile farming techniques

Care:

Baby Nile crocodiles seem to prefer and benefit from slightly higher temperatures than older juveniles.

Some farms maintain them successfully at 34 ° C in the first 4-6 weeks. Before lowering temperatures to 30 or 32 ° C.

The young could need to be offered live prey, winged termites can be used, tadpoles and small live fish, to induce them to feed.

The movement of the prey seems to be the key element, and if you throw them small pieces of meat or fish they usually catch them. Once some individuals begin to eat, the rest follow them.

Conclusion:

Although there have been no studies regarding egg production of crocodile nile there are certain yields that have left good results.

For example, the relation in time of the first laying of eggs is faster by female crocodiles that are in captivity.

Something that this race, without doubt, makes clear is that it produces eggs for many years. And that the young should be in good condition, and well-fed for their growth.

Regardless of where they are raised, whether in the wild or captivity, this breed can nest as long as it is in conditions that resemble its natural habitat.

The crocodiles that have been bred in captivity do not have as many restrictions in terms of care. Nor as regards the laying of eggs, as do those that are raised in the wild.pace.
