a simple plankton catcher

a simple plankton catcher

Postby Shrimper » Mon Jul 30, 2007 6:43 pm

It's done by most ecologists and some marine aquaculturists need wild plankton for some experiments. This model has been designed taking ideas from friends, professors and researchers ideas that use different methods to catch some plankton.

These can be applied in any beach but due to large quantity of detritous it may lead to the cloggin of mesh's.

Here is the picture. Feel free to comment or improve. No copyrights at this time so Open source :)



ps: i will try to use it in next week, and i will report catching rates.
Copepod are easily catched with 400 um (in the spring they are full of eggs that can be used to estimate abundancy production)

You should use 200,not 400 mic.And a light source could help if you leave it overnight.

That looks interesting, any change of photos when it is in action?
Have you had any luck with any amphipods caught when it comes to breeding cleaner shrimp? I will try "tigger pods" soon.

Thanks for sharing.

I will be collecting in the Algarve. The "Ria Formosa" ecossistem and "Ria do Alvor" ( intertidal ambient) is full of them in these time of the year, i will try to go to a calm beach too, and we work with a friend that owns an inland aquaculture so i will try in their ponds to see what life is in there.

No i'ven't seen it, the calanoid hunting technique where did you post it ? made me curious :)

A small world :D Jorge Corga is also collecting copepods
in the Algarve,in a "lagoa" with flamingos.He found SW Moina instead.

See "About calanoid copepods"at the zooplankton forum.
