I am looking for a reprint of the following paper.
Kullander, S.O. and R. Britz, 2002. Revision of the family Badidae (Teleostei: Perciformes), with description of a new genus and ten new species. Ichthyol. Explor. Freshwat. 13(4):295-372.
It would be appreciated, if you send a soft copy reprint.
Many thanks.

I am looking into bites rates of Indo-Pacific parrotfishes (i.e. bites per minutes), more specifically the the morphologically similar species Hipposcarus longiceps and H. harid. These data are required to convert abundance- and biomass data into reef bioerosion rates. There seems to be plenty of information on other species of parrotfish, and I have started to wonder whether I missed something and Hipposcarus species (categorized as scrapers) actually do not remove any or only negligible amounts of reef substrate while feeding? 
I would appreciate if anyone could point me to a publication featuring this information. Thank you.
Relevant answer
Answer
just in case this is relevant for anyone... just published:
Hoey, Andrew S., et al. "Regional variation in the structure and function of parrotfishes on Arabian reefs." Marine Pollution Bulletin (2015).
includes feeding rates of the ominous Hipposcarus harid (among other species)

Hi Eric,
have you tried to ask for some specimens in French and Belgian Aquariums as in France: Oceanopolis of Brest, Aquarium of La Rochelle, Nausicaa, Marineland etc.?
Good luck

We are trying to collect biological, ecological, socio-economical, even cultural data on groupers and their fishing in a bay in somewhere in Eastern Mediterranean for a PhD thesis project. It will take at least 3 years. We will use both primer and seconder data for that. At the end of the overall work we will organize several meeting and prepare a draft management plan with the full participation of interested users/stakeholders. Therefore, we are open to any kind of contribution for our work at the very beginning.

Hello Vahdet
This groupement can be interested by contributing to your work :
However, we are collecting now biological, ecological, socio-economical (not yet cultural) data on marine biodiversity in differents locations in Western Mediterranean in the consortium "indexmed". (http://www.indexmed.eu )
The future aims is to respond to Call for project H2020. If you re interested in this project, don't hesitate to contact us!

I will calculate the theoretical number of Artemia needed to start feeding a certain amount of Perca fluviatilis larvae.
Relevant answer
Answer
The feed intake and evacuation rate of catfish larvae fed Artemia decapsulated cysts could be used to derive some information. We estimated the daily number of Artemia cysts present in the fish gut at the start of exogenous feeding and in two and four days after that. Using the individual dry weight from cysts and that from from nauplii you can estimate of how many Artemia could be fed to the fish. Of course, it is not the same feeding an inert particle as the decapsulated cyst compared to live nauplii, but you can have a figure of how much feed (in dry weight basis) can be consumed by your fish larvae. This paper was published in 2010 in Aquaculture International, it is available in my profile. Also check for the individual dry weight of Artemia during the development from cysts to newly hatched nauplii in our 1998 paper from Aquaculture (also in the profile). Hope it helps.
