Any help or input will be thanked!

Recommended Posts

Howdy yall, im currently working on an Ag project of mine and it requires finding the respiration of fish. Right now im trying to figure out what kind of fish i should use. Depending on ease, size, ect... Im figuring the bigger the fish the easier it would be to tell i think. So im kind of pending on using, a smaller Largemouth bass or a 3-4 inch Bluegill.

Any help or input you can think of, or if you have any knowledge in this area it would help alot! Thanks everyone and have a good un!  8-)

If you test on one you catch, you will be getting an affected reading.  The fish will be stressed and in a state of survival, certainly to be reflected in heart rate.

I have no experience with this stuff, but if your just looking to count "breaths", I would head to BPS or Cabellas and use the Giant fish tanks.  Probely be pretty consistent with nature, being used to seeing people and all....

Send an e-mail to Dr. Keith Jones, Director of Fish Research at Berkley.

Dr. Jones will answer you and probably also give you some insight to your query.

You may have to "Google" his name or try to find him on the Berkley Fishing or Pure Fishing web sites.

I am sure you will want to know where to find data on both resting and stressed bass; any seasonal changes; spawning; or other species that would be good subjects.

Have you spoken to your librarian to find out how to search for Ph.D. dissertations?  The data may already be out there in other college libraries to help you on how to conduct the study and what is the best type of fish to use.

Let us know what you find out.  :)

I just seen the answer to your question a few weeks ago but try as I might I can't remember where.  Keep looking though because I know it's out there.

what was the question?

hes trying to find the respiration of fish. id check near the gills. its gotta be around there somewhere. let us know if you find it.

Well, try as I might, after going back to reread the question, imagine my surprise when there was no question.  I totally understand now why I am a newbie and you are a junior.  I only wish I could have directed him to the gills.  Oh well, I am here to learn.  Thanks for the help.

haha. great reply. im guessing the gills would be a good place to start. im kind of confused.

CatfishKing2010- what exactly about respiration are you trying to find?

how many times per minute they pass water through the gills? a pet shop might be an good place to gather some data if you dont have a large tank nearby. dont use the fish cowering behind the rock as a subject.

Sorry, well actually i believe i know how to check their respiration. By watching the gill moments you can tell. From what i've been reading its best to set a stop watch for a minute and count the movements of the gills and that will tell you the rate of respiration.

What i was wanting is more in depth on anything i should know! Already yall helped me lol. I didnt even think about how a fish would be stressed from being in a new enviorment.

Also i planned on checking a few different variables that could change their respiration, inluding increasing and decreasing the PH of the water. But my Ag teacher suggest i kept it alittle more simple and recorded more data on the few things too have a more accurate reading.

It sounded good to me so that what i plan on doing lol. Any new information will be greatfully thanked for guys! Thanks loads already!

Btw, thanks alot SAM i will have too send this fellow a email. From what i hear, the guys at berkley are outstanding reasearchers. Cant wait to find out more!

Generally, these types of projects use Zebra Danios, Brachydanio rerio.  They are available at any pet shop or scientific supply house.  You'll want the straight finned variety.  You'll need a small observation cup and magnifying glass.
