A shrimpy question from Little Harbour….

Inquiry from a Little Harbour resident….

Still don’t know what the macrobrachium shrimp are – and would really like to! – but now I have another mystery.

There are small red shrimp living in holes in the mangrove swamp behind Bookies Beach near Little Harbour. I think they are cinetorhynehus manningi. Usually I see one or two hanging out on the muddy bottom of a hole. Two days ago, I found at least 50 all clustered tightly on the vertical side of a hole. Went back same time same hole this morning, hoping to get a picture, but only saw the usual one or two.

Anybody know why they would “herd up” like that? And if and when I would be likely to catch them doing it again? I’ll keep trying anyway.

Craig Layman
My lab’s interdisciplinary pursuits provide for a multi-faceted understanding of environmental change in the coastal realm. We are ecologists, asking questions that span population, community, ecosystem and evolutionary sub-disciplines. We often use a food web based perspective, exploring top-down (e.g., predation) and bottom-up (e.g., nutrient excretion) mechanisms by which animals affect ecosystem processes. All of our efforts are framed within a broader outreach framework, directly integrating science and education, using approaches such as this website.

    Hey Craig!

    If you want to send us the Macrobrachium, I can identify them for you! Also, if you can catch the red shrimp send them my way and I can confirm the ID. I have a feeling they are not Cinetorhynchus manningi. I have a student working on several species of shrimp across San Salvador and eventually Abaco and Eleuthra. We can help….
