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.

That photo illustrates what a definition cannot. It also translates what a translator could miss. It's worth taking the time to think about. I'm wondering, Aufwuchs is a sort of colloquialism. Are there words from other languages like this? I'm wondering if there are people struggling with certain words that don't translate from their language into English. Maybe I'm overthinking.

Vomer: The bone on the palate, i.e. the "roof of the mouth."

Distal: Away from a point of reference, usually the center of the body. Opposite: proximal.

Proximal: Towards a point of reference, usually the center of the body. Opposite: distal.

Trophic Level: A stage in the food chain a species occupies. Example: A big fish eats the small fish, which in turn eats an even smaller fish.

Naked: Referring to a fish without scales.

F1: The first brood from a particular set of parents. In the aquarium hobby, it may refer to the first brood from a set of wild-caught parents.

Gravid: Referring to a female full with eggs.

GFCI: An abbreviation for "Ground Fault Circuit Interrupter." A type of electrical outlet that opens the circuit when excess amperage is detected. Acts as a safety device.

Salinity: A measure of dissolved salts in water.

F1 (first filial generation) does not exactly refer to the first brood from wild caught parents (all other subsequent broods from the same parents are also F1).

MatsP · Post by **MatsP** » 19 Apr 2006, 14:38

As an addition to GFCI:
RCD - Reverse current detector (and breaker). Detects faults in electrical circuits and breaks the connection to prevent accidents. See also GFCI.

F1, as Silurus points out, is the "First generation captive", but all broods from wild-caught fish would qualify here. And I think F0 and F2 needs to be defined too:

F0 - Wild caught fish.

F2 - Second generation captive bred - all grand parents of this fish was wild-caught.

Hi Amanda,
You might want to add these:
maxillary (barbels): barbels on the upper jaw.
nasal (barbels): barbels on the nose.
As far as I could see these are not in the list. Or did I miss something?

bronzefry · Post by **bronzefry** » 20 Apr 2006, 20:54

You didn't miss anything, Marc. I haven't gotten there yet.

Thanks for bringing it to my attention.

Just to clarify, RCD is something in Europe that is akin to GFCI but not exactly the same?

F1: First filial generation. All subsequent generations from the same set of parents are considered F1.

F0: Original set of parents.

F2: The children of a particular F1 set of parents. The "grandchildren" of a set of F0 parents. All subsequent generations from the same set of parents are considered F2.

These are actually terms from "Genetics 101" if I remember correctly. Drosophila sp.in mashed potato flakes? That was a very long time ago!

I certainly don't want to rush you. It just so happened that I noticed that mental barbels were already in the list. Which has become quite a list by the way and is an asset to the site. Well done!

I beleive from what I just read about GFCI that the RCD is the same as GFCI. Except that the GFCI is actually misnamed, since it's actually doing the same as the RCD - it's measuring the balance between neutral and the phase/live/hot wire (the not-neutral wire).
Compare this:
http://home.howstuffworks.com/question117.htm
with
http://www.powercords.co.uk/howrcd.htm
(Yes, horrible unreadabla background!)

A proper ground fault breaker would actually detect current on the GROUND lead and break the circuit based on that criteria.

And by the way, the correct wording for RCD is apparently Residual Current Detector.

It may be sufficient to state that GFCI in the US are called RCD in the UK (and possibly elsewhere).

In the F0/F1/F2 definitions, I would definitely say that F0 means wildcaught fish - it's not the initial generation of a species, but the generation starting the captive generation...

Thanks for the links, Mats. I just adore that background. They aren't trying to sell us anything, are they?

Useful information, though. Here's the comparison:
http://everything2.com/index.pl?node_id=1513338
The US market is dominated by GFCI. The UK is dominated by RCD. A GFCI needs to be in each individual outlet. An RCD is in the circuit box. More GFCIs required per home.

F0: An original set of parents in a breeding program. May also refer to a wild-caught fish kept in captivity.

F1: The first filial generation. May also refer to the first children of a particular set of wild-caught parents(F0). All children of the F0 parents will be considered F1.

F2: The second filial generation. May also refer to the "grandchildren" of a particular set of wild-caught parents (F0). All "grandchildren" of the F0 parents will be considered F2.

I'm sure I bungled that up somehow.

GFCI: An abbreviation for "Ground Fault Circuit Interrupter." A type of electrical outlet that opens the circuit when excess amperage is detected. A safety device more commonly used in the United States and installed in individual electrical outlets. Also see RCD.

RCD: An abbreviation for "Residual Current Detector." A device installed on the feed side of a circuit panel. This is tripped when excess amperage is detected and protects the circuit breaker. A safety device more commonly used in the United Kingdom and installed in circuit panels. Also see GFCI.

Mandible: Lower jaw.
Maxilla: Upper jaw.
Maxillary Barbels: Barbels on the upper jaw.
Nasal Barbels: Barbels on the nose.
Protrusible: A mouth that can be extended. Scobiancistrus aureatus has a protrusible mouth.

Just a quick note to say I'm going to "unstick" this topic as it doesn't appear to need any help staying at the top of this forum which I am gradually emptying anyhow.

Cheers,

Jools

Jools,
If you only knew how many paper sticky notes, notebooks, reference works, etc. were surrounding me at the moment, the juxtaposition would make quite a photo. That alone should keep this post going. So much for the "paperless office" I was trying to acheive.

I have quite a list of words today. (I'm going to insert the previous words first.)
Amanda

bronzefry · Post by **bronzefry** » 22 Apr 2006, 16:15

Evaporation: Conversion from a liquid state to a gaseous state.

If anybody would like to jump in on Evaporative Concentration, please feel free.

Necrosis: The death of cells, especially next to living cells.

Osmosis: The movement of water across a semi-permeable membrane from an area of higher concentration to an area of lower concentration.

Osmotic Pressure: The force that moves water across a semi-permeable membrane.

Osmoregulation: An organism's ability to maintain the proper balance of water and salts.

Heterospecific: From a different species.

Olfactory: Relating to the sense of smell.

Gustatory: Relating to the sense of taste.

Concave: Curved inward.

Convex: Curved outward.

I'll do 10 at a time.
Amanda

I looked up the definition of "aufwuchs" in German. It means "growth." I'll add this to the definition.

Daphnia: A type of water flea which is used as a fish food.

Brine Shrimp: Artemia salina. A common fish food.

Endangered Species: An animal or plant that is very close to extinction.

Endemic: A species restricted or contained in a specific area.

Acoustic: Relating to the sense of sound and/or vibration.

Analagous: A structure that resembles another structure in function, but not in form.

Homologous: A structure that resembles another structure in form, but not function.

Anthropomorphic: Giving human attributes to animals. Example: Bugs Bunny is able to walk like a human being. This is the Anthropomorphization of an animal.

Seine: A net used to encircle fish.

Quarantine Tank: An isolation aquarium for new arrivals or sick fish.
Amanda

Getting back to the barbel thing one more time:
are Mandibular barbels the same as Mental barbels?
Or are mandibular barbels the outer pair and mental the inner?

MatsP · Post by **MatsP** » 24 Apr 2006, 13:34

On RCD's - they don't HAVE to be wired into the consumer unit [formerly known as the fuse-box]

Evaporative concentration: The process where something dissolved in water (for example salts) is concentrated because of the evaporation of the water. Since the salts do not evaporate, the concentration becomes stronger as the water evaporates.

Some more off-shoots of the ones listed above.

Hospital tank - a tank set up specifically to hold fish that need medical treatment. It's often best to isolate fish with desease and treat them out of their normal tank - some medications are bad for the good bacteria in the filter so the tank will need cycling after medication, and some fish are sensitive to medication in itself.

CITES - Convention on International Trade in Endangered Species of Wild Flora and Fauna. It's an agreement between governments to restrict trade in species that are endangered. See http://www.cites.org for more details. There are three levels of CITES "listing", each in it's own appendix. Appendix I is the most threatened of extinction, Appendix III least threatened.

Protrusible: A mouth that can be extended. Scobiancistrus aureatus has a protrusible mouth.

That should be Scobinancistrus [with an N after the I] - and I suspect that other Scobinancistrus species have the same, but that may not be the case...

Oh, and looking at your link to RCD's, I think they have it wrong. Neither of the devices ACTUALLY detect current between HOT/LIVE and GROUND - both go between HOT/LIVE and NEUTRAL (or whatever you call the "second" wire). But it's correct that modern installations in England have RCD's on the consumer unit/fusebox (and supposedly a new RCD for each separate building too - so my Fish hut has it's own RCD now that we've got an updated electrical circuit). And of course, if you have the RCD break almost the entire house's electrics, it needs to be rated for more than 20A or so...

All Scobinancistrus have an extensible mouth, I'd suggest veering away from mentioning names whever possible however as classification changes can make things go out of date very quickly. Jon Armbruster, for example, considers Scobinancistrus to be a junior synonym of Panaque, while we don't follow this view, if it gains wider use, we will...

Jools, I'll change that to "some catfishes have protrusible mouths to catch their prey." There's a photo in one of the Datz books. The thing looks like a vaccuum cleaner hose.

Mats, you're a mindreader. I have CITES on my list as well as endangered species,ICZN and quarantine/hospital tank. I'll change around the RCD and the GFCI, since I found a unit at Home Depot the other day that is an extension cord with a GFCI built in. It doesn't have to be hard-wired, either. It cost a pretty penny.

Any barbels we've left out?
Amanda

bronzefry wrote:Any barbels we've left out?

Actually yes, the barbel. But this one, being a Cyprinid, is not allowed to enter the list anyway

Amanda, could you link Mandibular to Mental one way or another? That'll be all for barbels. Promise!

bronzefry · Post by **bronzefry** » 24 Apr 2006, 22:11

Mats, sorry I didn't comprehend your post until about 30 minutes after I read it.

Thank you for expanding on the words.

Yes, I need to ask Jools. How do I do that again? The barbel linking thing? Also, is there a way, in the future, in your spare time, we could add url links to a definition? Is that too much for now?

Marc, I'm sure someone will find a new type of barbel on a yet-to-be-defined catfish species.

Amanda

MatsP · Post by **MatsP** » 25 Apr 2006, 12:10

Amanda,

I'm sorry I'm not explaining things properly - I'll try better next time

And now some other off-shoots from what you wrote lately on foods:

Earthworm - Common earthworms are sometimes used as food for aquatic fish.

And related to Endemic:

Native - Used to describe a species that is naturally living in a particular area.

Introduced - Describes a species that humans have transpoerted and is now living in the habitat.

Indigenous - Native, but not restricted to that area.

Thanks, Mats. Here's a refinement of:

Evaporative Concentration: The process where dissolved substances become stronger when water evaporates. Example: Between water changes in an aquarium, water will evaporate causing waste products (nitrates, nitrites, etc.) to become more intense. This is called Evaporative Concentration.

Since I had a difficult time finding this definition, maybe we should take our time and bounce it around a bit.

Predator: An animal that lives by killing others.

Channel: The main part of a river.

Backwater: A quiet pool off of a stream.

ICZN: International Code of Zoological Nomenclature. The group that writes the standards for naming plants and animals.

Nomenclature: The system of scientifically naming plants and animals.

Caudal Fin: The tail fin.

Caudal Peduncle: The base of the tail which acts as a "wrist."

Rictus: The corner of the mouth.

How about this:
Predator: An animal that survives by capturing and eating other animals.

Did we miss Rictal Barbels? I was looking through Identifying Corydoradinae Catfish and it kept popping into my head.

Rictal Barbels: Barbels extending from the corner of the mouth.

There is the Code and there is the Commission. The abbreviations refer to the Commission (International Commission on Zoological Nomenclature, the governing body), not the Code.

Photoperiod: The amount of light in a day, either natural or artificial.

Chelation:A chemical method of binding metals such as iron for use in plant fertilization.

Invasive: An introduced species of plant or animal that causes damage to an ecosystem.

I'm going to try a different approach to GH and KH:

Hardness: The amount of calcium and magnesium ions in water. May be measured in ppm or mg/l. Hard water has more than 200 ppm. Soft water has less than 100 ppm.

Feel free to expand on the above.
