This overview is currently under construction.
Periclimenes sp. - Group Overview

1 - Species covered in this forum:

The Genus Periclimenes

Species include: P. holthuisi , P. tosaensis, P. aesopius, P. longicarpus, P. venustus, P. magnificus, P. brevicarpalis, P. lucasi, P. kororensis, P. soror, P. imperator, P. tenuipes, P. amethysteus, P. scriptus, P. aegylias, P. perdersoni, P. anthophilus, P. yucatanicus, P. rathbunae.

2 – Common characteristics:
Members of this genus are very often associated with invertebrate hosts. Certain species within this genus are also associated with fish-cleaning behavior.

3 – Reproduction:

3.1 – Sex determination:
Separate sexes.

3.2 – Sexual organization:
Pairs or groups.

3.3 – Sexing:
Females are usually larger in size. If impossible to judge by size, gravid shrimp are always females.

3.4 - Pairing / Setting Up Broodstock:
Some species are obligate associates of echinoderm/cnidarian hosts. Without the presence of their hosts they often fair poorly in captivity.

3.5 – Courtship:

3.6 – Spawning:
Larvae released usually during the night every 12-14 days depending on species. Shrimp normally moult within a few hours of larval release.

4 – Eggs:

4.1 – Size:

4.2 – Quantity:
Not very prolific due to small size of shrimps, possibly estimate of less than 300 eggs.

4.3 – Oil globule present/absent
Eggs carried by the pleopods.

4.4 – Incubation period/Hatching temp:
Eggs are held normally held for 12-14 days depending on temperature and species. Hatching temperature is usually around 25 to 28 ºC .

5 – Larvae:

5.1 – Size at hatching: About 2mm
5.2 – Yolk sac present at hatch: Yes
5.3 – Mouth present at hatch: Yes
5.4 – Eyes developed at hatch: Yes

6 - Rearing:

6.1 - Breeding & Rearing Techniques
Pay attention to special requirements. Some species require the presence of their host to complete metamorphosis.

6.2 – Day at first feeding:
Although yolk reserves can sustain larvae for days, they are best fed immediately after hatching.

6.3 – Feeding scheme:
Newly hatched brine shrimp in the beginning appears to be too large. Rotifers and microalgae seem appropriate for initial feeding.

6.4 – Age at meta:

7 – Species been reared successfully

8 – References

8.1 - Articles


8.2 - Web Content

FuEl, are you going to give EACH GENUS an overview here, or compile all the genera that make up "Snapping and Grass Shrimp" into one sticky? Just a curious question :)

I'm not too sure either. Some genus are very different from others in terms of commensalism and other issues. For instance, Periclemenes and Urocaridella are quite different as the former genus contains members which are obligate symbionts of coral/invert hosts. I'll have to think more about this. Maybe I'll lump everything into one sticky once I think of the appropriate way to list the differences.
