I’ve read up that a few fish (including the Atlantic tarpon) can supplement their oxygen levels by taking in air from the surface of the water if oxygen levels are too low. Is this unique in their anatomy? And what is stopping other fish from doing the same?

Atlantic tarpons are facultative air-breathers, in well-oxygenated waters they are able to meet their oxygen requirements without breathing air.

When swimming in oxygen-poor water, they can breathe air from the surface using their swim bladder as a primitive lung. This adaptation allows them to survive in water with low dissolved oxygen concentrations such as commonly encountered by juveniles in hot, stagnant mangrove marshes.

However, after several unsuccessful attempts to reach the surface they have emptied their swimbladders and become negatively buoyant until allowed access to the surface again.

Many fish can breathe air via a variety of mechanisms and it is primarily of use to fish that inhabit shallow, seasonally variable waters where the water’s oxygen concentration may seasonally decline.

I recall that there was some controversy a few years back when the now famed trout swim bait was first developed. The maker of it was almost busted for using live trout for bait. Anybody else know the story here?

not so much of a controversy. more of an urban legend.
when the castaic trout was introduced, it’s appearance to a live trout was so close, many anglers on the shore and even in other boats thought it’s user was tossing a live trout. especially when fished during a fish stocking. "Hey! that guy’s catching trout and using ‘em!". when viewed from a couple hundred feet away, that is what it looked like. didn’t take long for the warden to recognize these guys.
and the AC plug was mentioned. alan cole had the colorado river stripers to himself for a while on his big plugs. could have also been thought to be using live fish. l seem to recall some problems he was having but as far as l know, he never got ticketed. not real familiar with his story. l do have one of his originals in my lure collection. picked it up at a swapmeet for a couple bucks.
nowadays, it is rarely given a second thought with all the big swimbaits being marketed, up to even 16 inches.
until the AC plug, very few freshwater lures were much larger than 5 or 6 inches. using a lure of 12 or 14 inches (bigger than many saltwater lures) was unheard of unless you were a musky angler, and socal bass fishing wasn’t at all connected with musky fishing. otherwise, musky lures would have been favored for years, which they weren’t.
some lifelike ones now sell for as much as 300 dollars which puts most out of my price range, so l built one of 16 inches and used it a few times (a bitch to cast). had a couple followers on it but no biters.

free if possible
i was talking about the tv show but tanks any way

You can find some amazing editions of "The Compleat Angler" by Izaak Walton on Google Books:

http://books.google.com/books?q=compleat+angler&btnG=Search+Books

I’ve never looked at them all, but a couple years ago I found one that had some cool illustrations and exceedingly detailed footnotes. It was from the 1920s, I think (don’t have it with me). At first I just downloaded the Acrobat file and I would read it on my computer, but last year I printed the entire document (double sided) and then took it to a copy shop and had them cut it down to the original page size and bind it. Cost me about $2 in paper and about that much at the copy shop. It’s about 2 inches thick and has tons and tons of cool info and images in it. It also includes Joseph Cotton’s continuation of Izaak Walton’s story, which is worth having. You can get a copy of "The Compleat Angler" for a few dollars at any ordinary bookstore, but it will be nowhere near as jam-packed as some of those old, unavailable editions on Google Books.

Sorry — I’m not familiar with "Passion for Angling" and I didn’t find any free books by that name in Google Books. I did a quick search on Hyuel Morgan and found nothing at all related to fishing.

Seeing that you’re in the U.K., I might ask if you’ve ever read "Fly Fishing: Memories of Angling Days" by J.R. Hartley? That might be a dumb question, but is an such an excellent book, not to mention hysterically funny at times. I could never say enough good about it.

I was just wondering how many fish (carp or tench) could potentially be stocked into a body of water. For example into a body of water around 1 Acre ranging from 1 feet to 5 feet in depth?

wow! one is like, way too many!

Someone told me the show on mtv called "Is she really going out with him" filmed in tarpon Springs or in pinellas county?? If so which episode is it and whats his name??

Thanks

oh my gosh i live in that area, how exiting… but i can’t seem to find anything about that show being filmed in that area so my guess is probly not, sorry, hopefully im wrong

I understand this is runoff season, but does that affect the quality of fishing? Would you suggest any other state for trout fishing in late May? I’m trying to plan a trip around Memorial Day weekend.

Thanks in advance!

at one time i thought the eagle river by minturn just west of vail. but i think thay let one of the zink mines drain its crap out years ago . maby the fishing is better now. it was great trout fishing

Published about 40 - 50 years ago. Treated each species of fish. discussed paternoster rigs and indicated that did not know where the name came from.

If you are talking about the "Mc Clanes" thick green hardcover called "the fisherman’s encyclopedia" I have two, but below is one (though a second edition) available on ebay.

What type of line should be on spinning reels??? What type of line should be on baitcasting reels???
I bass fish. Either mono or flouro for spinning and baitcasting?

l use regular nylon mono on all of mine. both spinning and BC.
4,6 and 8 on the spinning reels and 8,10 and 12 on the majority of my baitcasters.
use a quality mono. l like maxima ultragreen, sufix stealth and silver thread. but there are other ones equally good. l have just had the best results personally with these.

Jimmy has caught two fish in Yellow Creek. He has tied the line holding the 4.90 kg steelhead trout to the tail of the 2.35 kg carp. To show the fish to a friend, he lifts upward on the carp with a force of 77.3 N. What is the tension of the rope connecting the steel trout and carp?

The acceleration of the two fish is first found as the difference between the total weight and the lifting force = total mass x accel;

F - (mg + Mg) = (m+M)a

77.3 - (4.9+2.35)(9.8) = (4.9+2.35)a

a = 6.25/7.25 = .86 m/ss

The tension in the rope is then found by writing the forces just on the trout (bottom fish);

T - mg = ma

T = m(g+a)

= (4.9)(9.8+.86)

= 52.2 N

I have been tying the double fisherman’s knot in webbing and it seems to hold very well, but now when reading about the internets it appears that the water knot is the recommended webbing knot.

I was wondering if anyone could tell me why the water knot is so beloved, and if the fisherman’s knots are dangerous with webbing and why.

I never use a double fishermans in webbing, always go with a water knot. This is what all the books and pros say too. I would imagine this is because the double fisherman knot cannot be dressed very well with webbing, and it could slip through due to twists. The water knot is much neater with webbing and simpler to tie.
