BREEDING SHRIMPS

Shrimps can breed in two different forms, but form of breed is not a trait saying about differences between kinds. Breeding of shrimps is highly conected with moulting - untill young shrimps are born female can't change her armour, that's why copulation takes places just after moultation.

NO LARVAE STADIUM ((hemimetabolics) - characteristic for most Caridinas and some bigarms shrimps (like Macrobrachium assamensis). Youngsters go throught all larvae stadiums in eggs and come out of them as small shrimps. From mature ones tells them apart lack of sex organs, which will be formed in next moultations. Because they are fully formed and quite big (what makes that higher percentage survive), number of eggs carried by female is not higher than several tens. Young ones eat the same food as parents from the beginning.
These shrimps are easy to breed and grow up in tank conditions. The most important stage ist first moultation, that's first 24 hours of life. Some offspring might not survive it, especially when there are fish in tank. With caridinas we don't have to worry about consuming offspring by parents, but we have to when we have bigarms shrimps (we have to prepare lots of hideouts or take them away from general tank otherwise they might be eaten).
In some species offspring has same pigmentations straight ahead, others are firs transparent in the beginning and need time to become colour.
