One bad infected fish in a pond infects all the good fish, while, the reverse is NOT true! One good fish amidst a school of infected fish in a pond, does not cure all the infected fish. Same is true in case of poultry birds and many other species of animals in Nature. Does this mean that the negative forces operating in Nature are more powerful than the positive ones ! ?

Good and bad only exists in human mind. Spread of a virus is good for that virus, and for whatever thing that fish ate. It also helps that one little & weak fish that just happened to have natural resistance to the virus - it would re-populate the pond with it's offspring.\n\nNature is about balance of many things that fight for their own survival against everybody else. If the balance gets upset by some force, some species benefit from it, and some loose.

no, because fish have gills (breathe on the outside) unlike us we have lungs in the inside.  In my aquarium tank I have a small mouth Bass & Yellow Perch, when i feed my bass minnows he would have three minnows in it's mouth (minnows literally sticking out it's mouth)/ my perch as well.  They will swim around with half a minnow sticking out it's mouth and act like it's no big deal.  You will see this with bluegill they will take the worm and swim around with it hanging out it's mouth.  I just feed my fish (thanks for reminding me) and I took pictures so if you want to see them just e-mail and I'll send it to you.  \n-About the dead smaller fish stuck in it's throat some fish I catch may puke up fish due to exhaustion.  When i go fishing for walleyes and northern pike I've had them cough up fish on me.  I've had bass do the same.  \n-Death? He could have died due to foul hooking (not meaning snagging) but if it hook in the middle or back of the throat can kill any fish especially if it's kept out of the water to long, just cut the line and release.  It doesn't work out all the time.

Your argument has some assumptions, assertions, and logic that are not sound.\n\nFirst of all, you only multiply probabilities together when they are independent variables - it would be easy to argue that many of the items that you mentioned are interdependent.\n\nAlso, I think you misunderstand what evolution of species is proposing.  Evolution does NOT depend on luck - it is instead an observation that lucky organisms survive and pass on their properties to their descendants.\n\nConsider bacteria - almost all mutations are harmful but a few bacteria have lucky mutations that make them immune to penicillin.  If penicillin is used on bacteria, only these lucky ones survive - and most of their descendants inherit the the same immunity-mutation.  \n\nThe original mutation is luck - the environment then selects and a small set of traits due to beneficial mutations persists.  And THAT is not luck, that is selection.  That's why the process is called "Natural Selection".  \n\nSadly, this is why almost all bacteria were zapped by the early antibiotics, and now (only 60 years later) we have hundreds of resistant strains.

After reading several articles both for the case that fish can feel pain and against this notion, and based on my own observations of how people react to so called "pain stimulus" as well as how fish react to so called "pain stimulus", I must conclude that indeed fish do feel pain.\n\nThe following are links to the articles I read that helped me reach this conclusion.  I hope this is helpful for you.

Basically, any dead fish can float downstream. Which takes more effort, to just give in to your flesh or fight against it? Not too many people wish to fight it. It is far easier to "go with the flow" than it is to be a light in a dark world.

i tell you what i believe .... and we are not being informed by the medical feild ,, but our naturalist are telling it !!!!its all over the net  ........our animals are treated for parasites!!!!!!!!!we humans are not !!!!!!when i was a little girl and let us go back to even  out ancestors  they  treated once a year for  parasites  but  why have we quit??????? not me i found a remedy  and all the hurts and pains that i began getting as i became  older has now dissappeared believe it  or not  i do a dailey parasite program have for several years now nothing compares to it   .... so why are our animals more healthy ????isnt it funny we worm our dogs, cats, horses, cows, and so on  what about  us?????? something  for u to think about

hell no , the exact opposite get the smaller ones out of the pond because they are the ones competing for resources with  the bigger ones so in order to prevent overpopulation kill of the smaller ones not the bigger ones, bigger gills have bigger babies

Ok, I'll bite, does Skippers need some schooling on proper fish treatment?  It makes me green in the gills just thinking about those poor fish... baited into beleiving that they'll be treated finely.

These bacteria probably have the lux gene which codes for bioluminesence. A resonable mechanism that would cause this to arise is mutation. These lighted cells would probably have benefited some how from glowing in the dark. Some deep sea fishes have bacteria which code for this gene (Vibrio fischer) Which may have helped these fish find food in the dark waters. Thus those fishes without this gene would have died out because of natural selection. What you could do is put these fishes with the bacteria that glow in the dark in the same pool of dark water as the fishes without this gene. Then provide a limited food source so that not everyone could receive food and only the strongest would survive. If the fishes without this bacteria eventually died out but the others stayed alive, you have proven your hypothesis. If not, then failure willl be an obsticle to overcome.\n\nHope i was helpful

Something very similar happened to me two weeks ago.I found a dead bird on my front stoop.It didn't appear to be injured and it looked like it was asleep.But ,it wasn't.I'm not a superstitious person,so I don't know anything about that.I do know that a few years ago all of the crows in our area died as a resulty of west nile virus.I suspect the dead bird I found, might have been sick from something like that.

Well at least your not lubing the small animals and shoving them up your @ss! Seriously, the only thing I'm concerned about is the cleanliness of the animals. Maybe you should start breeding them in a safe and clean environment. Good luck! By the way, stay away from my goldfish!

So funny thanks, have to tell my biology teacher that one, actually on second thoughts perhaps not the type of thing you tell your teacher. Thanks anyway xXx

Fish are subject to a variety of maladies, such as grubs or worms, which may be found in or on the skin, attached to gills, or embedded in the flesh. Although aesthetically displeasing, none of these parasites presents a threat to human health provided the fish is thoroughly cooked before it is eaten.

Its to fdo with the type of enviroment the bacterium is living in. Those that live in wet enviroments, eg in water or in your GI tract will have a method of motility in order to move around to obtain nutrients. Conversely those that live on bread for example, have their nutrients right there and so dont need to be motile. Of course, having said that, bacteria that are obligate intracellular parasites dont as far as im aware have flagella so there is probably something else involved there. Maybe its the spreading of its progeny.

There are certain fish, when introduced to a specific location will kill all the natural fish in the that area.  There is also a noxious ivy weed, I belive it is called Kudso, that will take over everything it comes into contact with, it grows extremely fast.  It has been known to take over entire fields, buildings, and towns.  It is almost impossible to eradicate.  I will modify my answer if I can think of the name of fish I am thinking about.  Something else, many years ago Hawaii was overrun with rats (or was it snakes?) so they decideed to bring in mongoose's (or is it mongeese? LOL), the mongoose ate all the rats (snakes?) and now they are no more.  It is illegal to bring a snake to Hawaii, so it was probably snakes.

well, i do know there's this blue chemical called biochemical oxygen demand(BOD) which is used to see how polluted water is from different sources. like, if you compare drain water and pond water. so if you put few drops in each water, and wait for one day, you'll realise that drain water isnt as blue as pond water coz drain water is more polluted. since there are more waste compared to pond water, so there'll be less oxygen. so yeah.

they isolate the two different strands.  think of it as looking in a lake and seeing a salmon and a bass.  even if you stir up the lake you still only see a salmon and a bass.
