Glossary questions and requests

Let's try this:
TDS: Total Dissolved Solids. A way to calculate water quality by measuring organic and inorganic substances present. Total Dissolved Solids are measured in mg/l(milligrams per liter) and may be measured in a laboratory or, more conveniently, by electronic meter. Similar to conductivity.

I could be wrong, but I think deionized and distilled water are one in the same. I've been searching for the term distilled and can't find it. Can anybody else find it?

Inorganic: Chemical compounds which are not Carbon-Hydrogen based.

Organic: Chemical compounds which are Carbon-Hydrogen based.
Thanks for the help, Mats.

Distilled water is pure water. It has nothing in it (except dissolved gases).
Deionized water has all of the ions removed from it (accounting for a large part of the dissolved impurities), but may still have nonionic organic substances in it.

In short, distilled is purer.

Thanks, Silurus.
Distilled Water: Pure water with nothing but dissolved gasses in it.
I'll wait to see if there are any more comments on KH, GH, etc before I put the whole thing in on Sunday.

The reason I added TDS meter as a separate entity was that it's actually measuring Conductivity and then uses a fixed formula to attempt to give a TDS value - it's not the same as TDS measured by drying out a liquid in a lab.

Say you have a solution of NaCl (salt) that gives a conductivity of 100 uS/cm. Then we create a different solution of CaCO3 to give the same 100 uS/cm. This will be less conductive per molecule, so we need more molecueles of CaCO3 to do that, and then on top of that, each molecule also weighs more, so the actual amount of TDS in the water is dramaticaly different. But the TDS-meter will show exactly the same reading, as it doesn't actually take into account what the ions giving the conductivity is, it's just using a "standard mix" that may or may not reflect what most water contains...

However, I suppose the definition you have is close enough to work - but there's a noted difference between the value that you get out of a lab-report (try TDS'ing a bottle of mineral water, and then compare that to the "Typical analysis" results that are written on the side of the bottle - add the mg/l up and you'll probably find that it's not matching up...).

Jools wrote:OK, on the anatomy front I've worked out what we're going to do. After a five hour training session this morning I figured out that flash was too hard to learn in the time I have available and wouldn't be as useful as I had imagined. Avoiding its use also keeps the site free of plug-ins which is a nice place to be.

It is also clear that flash skills aren't commonly found and, to enjoy the sort of participation we've seen with the glossary, many more people are more at home in an art application.

So, I've concocted a prototype page here: http://www.planetcatfish.com/core/anatomy.php

Have a play around with it, any comments would be appreciated before we strike out and use it. When that happens I'll be looking for folks to colour in parts of the catfish in red! If you feel the need to do that, use this master - http://www.planetcatfish.com/png/anatom ... blank).png - NOT the one on the page.

Added a couple more terms:

Colouring in is therapeutic! Any budding artists out there to help?

Jools

bronzefry · Post by **bronzefry** » 09 Apr 2006, 18:00

It is, isn't it?

I'm going to put the above terms in the glossary and prepare a slew of new ones. On a side note, I met Lee Finley this weekend and bought some books, including a biology dictionary, a dictionary of aquarium terms, and the Mergus Wels Atlas Band 2(time to learn German!).

Some typos in the anatomy page:

Barbel is misspelled (gee Jools, how could a catfish head like you misspell an essential catfish feature ;)?)
Genital papilla should be singular (since I don't think the fish is hermaphroditic).

bronzefry · Post by **bronzefry** » 09 Apr 2006, 19:06

New species? The bright yellow one that turns red when stressed in certain anatomical areas? It's a hermaphrodite!

Where's the holotype.....

A little secret is out! I type it wrong EVERY time I type it, it's one of those words I just know I always type wrong like "because" (becuase) and "the" (teh). This one got past me (no spellchecker ever picks it up)!

Biotope: A portion of an ecosystem with specific conditions and life forms. An aquarium may be set up to reflect a biotope such as a river.

Mouthbrooder: A fish that carries the eggs, and sometimes the larvae in its mouth. The eggs may be carried by the female or male, depending on the species.

Teleost: A bony fish.

Bifurcated: Forked or divided in two parts. Some catfishes have a bifurcated caudal fin.

Icthyology: The scientific study of fishes.

Turbid: Water clouded by suspended particulate matter.

Aeration: The process of passing air through water to exchange gasses. In an aquarium, this may be done with an air pump and airstone or a powerhead.

Standard Length: The measurement of a fish from the tip of the snout to the base of the tail.

Total Length: The measurement of a fish from the tip of the snout to the end of the tail.

Clutch: A group of eggs laid in the same place at the same time. Many catfishes lay their eggs in a clutch.

Villiform Teeth: Fine, long teeth that are crowded in together. This gives the appearence of a patch of velvet.

As usual, input is welcome!

Amanda,

Did you colour in the master copy above and resize it or did you take the image from the page? If you did the latter, no great shakes as I can redo both images but, in future, can you use the bigger file as stored at http://www.planetcatfish.com/png/anatomy/ .

If you have the larger images, please email them to me at webmaster at planet catfish dot com.

Thanks for this,

Jools

Jools,
I colored in the page, not the master. I did go and download the master after I read your post, made the corrections and e-mailed them to you. Not quite sure I resized them correctly. Please let me know.

Are there any catfish that truly mouthbrood?

Biodiversity: The sum total of all living things in an ecosystem.

Brood: A group of offspring that arises from a clutch of eggs.

Courtship: Ritualistic behaviors that occur prior to spawning.

Yes, and many ariids, for starters.

Some ariids and at least one bagrid do I think.

Also you want the term lipbrooder for various loricarinae too.

Biofilm is another word for it and there is another that I can't remember right now. A good example for Aufwuchs: See Biofilm and link it.

Jools

bronzefry · Post by **bronzefry** » 13 Apr 2006, 21:21

Aufwuchs was one on my 3-page list. Thanks, Mats.

The fishbase definition also said it's another way to refer to the coating of detritus, etc.that forms on rocks and plants. Fish who eat Aufwuchs are limnivores. Otocinclus and Corydoras? I just Googled "lipbrooder." Two hits came up. Both were from here. Has anybody found the definition?

Mouthbrooder: A fish that carries the eggs and sometimes the larvae in its mouth. The eggs may be carried by the female or male, depending on the species. The species Phyllonemus typus from Lake Tanganyika is unique among catfishes in that the parents share mouthbrooding responsibilities. With Arius graeffei from the South Pacific, the male can carry up to 120 eggs in his mouth for 6 to 8 weeks.

(Thanks, Silurus.

Describe this:

A mouthful!

Demosthenes-wasn't he the orator with pebbles in his mouth? That would be a good scientific name. Almost always males for lipbrooders?

Lipbrooder: A fish that "sits" on fertilized eggs with its mouth as a form of parental care. A lipbrooder will carry the clutch of eggs with him until they are ready to hatch. Example: Loricaria simillamia.

Aufwuchs: From the German language. Non-burrowing organisms that grow on the substrate forming a coating of detritus. Also called biofilm. Also see limnivore.

Limnivore: Literally eating "mud-based" foods. Fish species that feed on Aufwuchs or biofilm. Examples of limnivores include Ancistrus, Baryancistrus, Chaetostoma and Hypostomus species.

Parturation: Giving birth.

Morphology: The scientific study of the structure and form of organisms.

Saddle: A patch of color that starts at the midline of the body and extends down the sides.

Neotony: A condition where charactaristics of the juvenile extend into adulthood.

Emarginate: Slightly indented.

Euryhaline: Life capable of tolerating a wide range of salinities.

Fusiform: Tapered on both ends. Cigar-shaped.

Jools, are you coloring the lateral or dorsal view?

I would say <em>Loricaria</em> spp. but if you do go with the one species, you've got a spelling mistake in the specific epithet.

I am colouring in whatever takes my fancy, so, both. I don't plan to do much over the next couple of days as I have a houseful of Clare's family for Easter.

Jools

No worries, Jools. I'll go with the Loricaria spp. I have many more words defined, but I think I'll hold off on posting them until after the holidays when more folks are around to take a look at them.

OK, note when writing <em>Loricaria</em> spp. the spp. shouldn't be italicized.

I have also finished the anatomy page and are linking it in to the rest of the site replacing the old one.

Looks great!

I see the "Catfish Anatomy" has been added to the drop-down menu, too. I'll go through the glossary to make sure I didn't use italics for the "sp." etc. in any other instances. I'd rather have things be correct.

Here are the FL, SL and TL definitions from the FAQs:

Standard Length: abbr. SL. The distance from the tip of the snout to the base of the tail(caudal fin).

Total Length: abbr. TL. The distance from the tip of the snout to the tip of the tail.

Fork Length: abbr. FL. The distance from the tip of the snout to the fork of the tail.

A bunch of others:

Vomer: A bone in the nasal area.

Bioload: The demand on lifesupport systems created by aquarium occupants. The more fish there are in an aquarium, the greater the bioload.

Estuary: A type of ecosystem that occurs where a river runs into the ocean. An estuary will have variable saline levels.

Genital Papilla: In some fishes, a tube extending from the genital pore, behind the anus.

Infusoria: Miscellaneous microorganisms found in detritus. When properly cultured, Infusoria make an excellent fry food.

Fry: Another term for a larvae or juvenile fish.

Aquarium: An enclosure, such as a glass tank, outfitted with lifesupport equipment for the purpose of keeping underwater animals and plants alive.

Distal: Remote.

The vomer is actually a bone on the palate (i.e. the roof of the mouth), and distal actually means "away from a reference point (usually considered to be the center of the body)". The opposite of distal is proximal.

The bone in red is the vomer:

I was out for a walk along the river avon yesterday and was reminded of this topic so took this picture.

I guess this opens up the whole, hoe do we add pictures to the glossary thing, I need to think about that for a bit.
