Eggs of the BSF

The eggs of the BSF are hardly visible. They each weigh around 25 micrograms. They are supplied in a certain substrate, in a jar with an air-permeable lid. A jar contains approximately 50 grams of eggs, plus substrate. Ideally, if every egg hatches, 2 million larvae can hatch per pot. But not every egg hatches and many young larvae also die (because they cannot reach the feed, for example). Take into account a result that 50% of the eggs purchased actually hatch and survive. The contents of the jar do not resemble the photo with eggs: that photo shows the eggs without substrate. But without a substrate, the eggs cannot be transported without major damage. The substrate is a buffer that dampens shocks during transport.

How should the eggs be handled?

A mixture of finely ground feed with water (relative humidity ca 60%) is deposited in the middle of a crate of approximately 40 cm * 60 cm. Around the mixture a layer of dry flour is dispersed in the crate. This prevents the young larvae from spreading outside the feed.

The contents of one jar (mixture of 50 gram eggs and additional substrate) are deposited gently on a sieve-on-legs (diameter approx. 10 cm). This layer of eggs must not be thicker than 1 cm. The sieve is placed in the middle of the feed mixture (at a height of approximately 5-10 cm above the mixture). After a week, most of the eggs have been hatched. The larvae have dropped through the sieve and find their way into the mixture of finely ground moist feed. From then on, the process of eating and growing begins. There are, of course, far too many larvae in that one crate. Its contents must be divided into approximately 100 crates of 40 cm * 60 cm, so that there are approximately 10,000 larvae per crate.

It is important for getting enough large larvae that they have enough space to eat. This means two things:

  1. Give them enough feed (rule of thumb: 100 ml feed per larf per day)
  2. Do not put too many larvae together. It is optimal that there are approximately 10,000 larvae in a crate of 40cm * 60cm.

How do you see that there are too many larvae together?

You smell it from the ammonia odor and you see that the larvae little move and grow insufficiently.
