Maybe you can help, how do you identify a 100% pure Florida? Especially if it is not a big fish.

Eerstens genetiese toetsing....waarskynlik baie duur en tydsaam.

By jonger visse,wel jy kan die verskil in skubbe op die laterale lyn tel Floridas het so paar meer,maw Northern bv 30 skubbe,Florida bv 35 skubbe.

Tot op ouderdom 3 jaar / omternt 2 kg is die 2 visse se groeispoed amper dieselfde,maar daarna vermeerder die florida se gewig amper 2 keer die vd northern, die northern se groei is ook beperk,maw bv max 5 kilos waar die florida to 10 kilos kan gaan.

Die kruising ( hibried ) tussen die 2 is 'n baie goeie vis itv groei,baklei vermoe ens en is net soos by honde, waarskynlik meer siekte en temp skommeling bestand.
'n Groot hibried se mond is ook kleiner as die vd suiwer florida vd selfde grootte.

Die kleure asook kolpatroon kan wissel,maar dis redelik moeilik om vas te stel...

Hoop dit help?

Dankie Herman, glo dit sal help. Beteken dit nie dat dit bitter moeilik sal wees om te bepaal of n sekere stuk water 100% florida's hou of nie? En as hulle in dieselfde water is dan gaan hulle inbread in elke geval! (Hulle gaan nie ophou teel omdat een 100% en die ander 90% is nie) My persoonlike opinie is dat daar is geen 100% florida's in hierdie land nie, tensy hulle 100% isolated is met geen inloop en direk vanaf Florida ingebring is, wat ek dink skaars is in die land. Dit verduidelik ook hoekom die SA rekord so laag is.

Hallo Hennie

Ek dink dis waar,maar ek weet van  " geisoleerde"damme waar suiwer vis wel in is,weer-eens pvt damme...

My vriend Chris pienaar het in 1997 'n 5 kilo plus Northern gevang in Senteeko dam naby badplaas.

Ons het daai tyd navorsing gedoen en toe bepaal dis nie 'n Florida nie!

Baie teorie...en so min tyd!!!!!

Groete

I though id never say this but Herman does make sealine more interesting. Although he did make all our blood boil when he first started I bet everyone always waits for his response as he's not shy to say what he feels. Keep it coming HN!

Herman first off let me say that if you think a person who has a high number of posts on a public forum is more qualified or has more right to an opinion than a new member you are sadly mistaken. I love the way some people jump on forums, make a thousand posts and then become self proclaimed experts. Maybe you need to go and look around at some other fishing forums before you make the assumption that this was my first post on a forum, maybe on this one but certainly not on dedicated bass forums

I will be as smartassed as I like, you can go fly a kite if you think I will shut up because you said so.:fbash


Right time for business.
Regarding the red sore or lesions on that bass's side, we are actually both incorrect.
After some investigation I found out that it is actually called "Red Sore disease"

This is a pic of a 2.5kg fish I caught at the BETT finals at Maguga last Sept
P1040979c.jpg


You can clearly see the lesion on the side of that fish.

Here's a nice pic of a red sore
img_3g1_epistylis.jpg



Quote:
[font="Arial, Helvetica, sans-serif"]The red sore on this bass is caused by the protozoan parasite Epistylis. There are many causes of red lesions on the skin of fish. A common cause is the bacteria Aeromonas.  Fish that are stressed from spawning activity, injury or poor water quality can be susceptible to these types of infections due to weakened immune system.

[/font]
Red sore disease usually involves several aquatic organisms, most of which are considered to be "opportunists." That is, these organisms are present in the environment in which fish live, but are only able to cause disease under certain circumstances. For this reason, the condition is most prevalent in the spring and fall, when the natural disease resistance of fish is low.

Red sore disease in game fish is common in the spring and fall, and often due to the effects of two opportunistic aquatic pathogens, Heteropolaria sp. and Aeromonas hydrophila . Heteropolaria sp. is a ciliated protozoan, found almost everywhere in fresh water. It causes problematic infestations on game fish. These protozoans flourish and attach to the skin, where they cause unsightly, bloody, ulcerated areas.

I am very familiar with what Dropsy looks like, I keep Koi and have had fish die from it and we see it often at Inanda in Tilapia, I have never seen a Bass with it, although it could happen.

Here's a good shot of what Dropsy looks like

Regarding the Florida strain, Goedetrouw was the only public dam legally stocked with Florida strain only. There might have been private dams stocked but no public dams.
Or the fisheries biologist that told me this must be lying?
I'm sure a few other fish have found their way into it over the years though. Although when you have spent as much time there as I have it is quite clear which species is present.

I know the whole history behind dotty,but thanks for the "lecture"!
I have done extensive research on Californian Bass and the trout feeding syndrome.

Big Bass,Carp and Barbel to me are like celebs. If you have seen them once,you wil regonise them again in future.

I am 100% sure that is the same fish.

The parasitic infection /sores could also be caused by leeches,this happen to Pike all the time after feeding, but if you reckon you know so much, the fish bottom left looks 100% DROPSY to me...

I think you need to do some more research into 100% pure Florida strain my friend, I know of at least 20 dams with 100% Florida - not Hybrids- in Mpumalanga....so better check your facts...

I even know of 2 Dams with 100%  Nembwe for that matter!
Also,in flood times dams that feed Goedetrouw could break and leak Northens into the system....


Shannon,seeing this is your first post...dont try to be a smartass...because Sealine has already got one...me!

Taken from the Florida Museum Ichtyology dept website

The two recognized subspecies of the largemouth bass are the northern largemouth (Micropterus salmoides salmoides) and the Florida largemouth (Micropterus salmoides floridanus).
The Florida largemouth has slightly smaller scales than the largemouth bass in relation to the size of its body. It has 69 to 73 scales along the lateral line, compared to 59 to 65 on the northern largemouth. It grows faster and reaches larger sizes in warm waters than the northern largemouth, leading to its popularity in stocking efforts across the U.S.

Here's the link to the page

The more I look at those 2 pictures of the very large fish, the more I am convinced they are not the same fish.
The biggest difference between the 2 is if you look at the head of the 8kg just behind the eyes there is a very pronounced dent in the head, the larger fish doesn't have it.
As fish get bigger the head bulge or hump gets larger not smaller if it is present.

Thanks man,appreciated!

Hennie S

Ek het aan nog 'n manier gedink om tussen Floridas en Northerns te onderskei...jy vra die vis na jy hom gevang het of sy pappa 'n Floridas of 'n Northerns ondersteuner is...LOL!

Shannon

Firstly let me say I respect your "doctorate" in bass influences on local species etc, BUT ...EXPERIENCE BEATS QUALIFICATIONS HANDS DOWN!!!!!!!!

I will unfortunatly have to wait for that August winds to pick up before I can launch my kite....I do however feel that you misunderstood something....I did not tell you to shut up,nor did I mention anything about "other" forums-I was referring to this one.

Regarding the red sores:

Quote:[font="Arial, Helvetica, sans-serif"]"The red sore on this bass is caused by the protozoan parasite Epistylis. There are many causes of red lesions on the skin of fish. A common cause is the bacteria Aeromonas.  Fish that are stressed from spawning activity, injury or poor water quality can be susceptible to these types of infections due to weakened immune system."

In my experience the EPISTYLIS and AEROMONAS will "attack" fish that was handled with DRY HANDS and the protective mucus layer/skin "burned" by AMINO ACIDS on human hands...

On the positive side....by peeing you of I actually got you involved and thanks for the pix, now everyone on Sealine can see what DROPSY looks like!...this also makes good reading dont you think?[/font]


Quote:"Or the fisheries biologist that told me this must be lying?"...hulle het jou 'n poep gevoer,sorry....LABA stocked pure "purchased" Florida fingerlings in several public dams here - Inyaca,Klipkoppie,Witklip....and so did several farmers....

Regarding the big fish - on the one pic it lies slightly on it side,due to the bloated belly, resulting in a different look on the gill plate.
If you enlarge the pics you will see the tail lesions/scarring matches...

But thanks for your research though!

Regards

Looking at the pic of that syringe at the dropsy pics made me think of something else too...

A. The Bass seems quite dead
B. It is severely bloated/swollen
C. It looks as swollen as a pregnant womens feet due to water retention...

What if the fish died in captivity and was then injected with fluids/water to look bigger and weigh more, the same as some frozen chicken companies do to increase weight?

Just a theory, but it is possible.

As a laaitie I often injected dead Platannas with "red cloud" fluid and a syringe, and it worked like a charm for the barbel.
We also injected them with air ( empty syringe ) to make them float/suspend just above the bottom.

You know what bugs me alot, why is it so dificult to post a new record if the previous one is rather old(70 odd years)

How could any one be 50% sure all the corect stepps were taken in the '40's? Let s say all is verified and its only 1 oz bigger, a tie? BS!

Why is it when another world records is broken its all fine, regardless of specie? But why if its a bass the yanks do anything in their their power to discredit it? Do they own bass angling? How many other okes around the world have been brain washed by the yanks that only they can hold a bass record, how many ppl on this site? Sure bass angling is big in the US, does that mean no other place in the world can or may have big bass?

Goeie punt Gerrit, maar die hele ding lyk net te "suspect"...

Ek twyfel nie dat 'n ander land die rekord kan breek nie.maar...

Kyk weer mooi na al die kiekies,gaan na Calfishing.com en lees die posts noukeurig...

Ek vertrou 'n JAP net soveel as iemand in die regering...

I find this conversation very interesting, it seems that the theories in this country is as rich as in the USA. I have a friend that use to be my boat partner when he was still studying (Microbiology) when he got his degree he went to the USA as he wanted to specialise in Fish Biology and further his studies eventualy became a Doctor. He currently lectures at Colorado University and works for USA Fisheries department. The thesis he did for his doctors degree was how bass relates to structure and the importance of structure to bass, the end result was suppose to assist anglers to catch more bass.

I contacted him re the identification of Florida's vs Northerns and he mentioned to me that studies has shown that the looks of a fish, including counting scales is only 70% accurate. He reckons that no fish biologist will put his c.... on a block by looking at a fish. The only accurate test is dna tests and for this you need the fish liver, he also mentioned that 95% of all fish DNA profiles is identical with a 5% variance that determines the species. The USA fisheries department have a database containing 3 million records of fish DNA and if you want a Florida DNA profile you have to purchase the entire database at $800. Needless to say I asked him if he can possibly give me a DNA profile of a pure Florida, if you want to do DNA tests and compare profiles you need to know what you are looking for.

Another interesting thing he mentioned is that 70% of Fish biology students that do their doctors do their thesis on Bass. The main reason for this is that Bass is such a big sport in the USA, 55 million registered bass angler in the USA at the moment. I was lucky enough to read his thesis but unfortunetly he cannot get me access to the other, I dont know the correct people at the Varsity!

GerritP, you ask if the yanks think they own bass fishing probably! That is where it originates from and you know them they have a world championship with only americans competing. Have to give them credit for the way they manage their waters and fisheries though.

Shannon, thanks for the info on dropsy very informative!

Herman, ek sal my volgend bass vra wie is sy pappa as ek hom in die live well sit!

Hi Guys

Must say it is real funny to read all the comments on the new record bass. Even the forums from overseas are having a free for all on the topic.

HennieS jammer ek kom nou weer terug maar ek stem saam met jou vriend van Amerika ek het Navorsing in dierkunde genetieka  gestudeer. Ongelukkig nie in visse gespesialiseer nie :fbash. Die enigste waqre of erkende manier om enige dier werklik te identifiseer is deur die genetieka te toets. Baie het al gese die een se kop en bek is groter as die ander maar dit is ook onwaar. By mense wel :::S lol.

Shannon thanks for the info, I don't think that the biologists know verything. Maybe they were talking about Natal. I know for a fact that several of the public dams in the Lowveld were stocked with Florida strain bass by LABA. These dams already had Northern strain in them. I think most of these dams have hybrid bass by now as these dams were stocked over 10 years ago.

I think the Yanks will stop at nothing to keep the world record with them. Pity for all the guys outside of the States. I guess we will have to wait and see what the Yanks say.

There is a video on Youtube. That fish was alive when he caught it. You can still see its gills moving. So don’t know if it was released alive or taken

Got this from one of the yank sites,

Interesting:wfish

 

 






"I am sure that anyone who follows bass fishing at all knows that the previous world record largemouth bass caught by George Perry 77 years ago, is being challenged by a Japanese angler by the name of  Manubu Kurita. The angler is sponsored by Deps Lure company in Japan.

The IGFA, The International Game and Fish Association, is the deciding voice in this whole matter, and everyone is awaiting news from them on the certification.

 

"I heard about it, but we don't have any details," said Jason Schratwieser, the IGFA's fishing records and conservation director.

Schratwieser said the bass would have to be 2 ounces heavier than Perry's catch to establish a new record.

 

"It will tie it if that's the weight,"  Schratwieser said, indicating that IGFA rules stipulate that for record fish weighing less than 25 pounds, the replacement record must weigh at least two ounces more than the existing record.

 

"It looks like the real deal," said San Diego County bass angler Mike Long, recognized as one of the top big bass anglers in the world."The girth looks right. Everything looks right about it".

said Ken Duke, senior editor for BASS publications:" It seems closer and more of a real deal than any situation we've seen."

 

Lake Biwa is Japan's largest lake and covers more than 259 square miles. It's also said to be one of the oldest lakes in the world. It is surrounded by mountains and famous for its scenic environs. Its crystal-clear water is more than 300 feet deep.

 

The thing about catching this in Japan is that it really goes against the grain of most hard core trophy hunters and bass anglers here in the United States for many reasons other than it wasn't caught in this country.

 

The first being that we already caught the world record in California a few years ago in Lake Dixon, which was 25.1 pounds, (on videotape), and it was not certified due to a technicallity.

 

The other thing is that Japan considers largemouth bass to be an invasive species and the bass are taken out and eaten! The restaurant on this particular lake serves largemouth bass on its menu!

 

And third, after spending thousands of hours fishing for these bass in California with swimbaits and other finesse techniques that require a great deal of patience and skill, to see it caught on live bait would just add fuel to the fire so to speak.

 

Lake Biwa is Japan's largest lake and covers more than 259 square miles. It's also said to be one of the oldest lakes in the world. It is surrounded by mountains and famous for its scenic environs. Its crystal-clear water is more than 300 feet deep.

 

In recent years Japanese officials have reacted to concerns by commercial fishermen there and tried to eliminate invasive species from Biwa, and black bass, or largemouth bass, are on that list of invasives. An unconfirmed report indicates that a 25-pound largemouth bass may have been netted by one of the commercial fishermen. The Lake Biwa Museum Restaurant serves largemouth bass on its menu.

 

The previous Japanese bass record weighed 19.15 pounds and was caught by Kazuya Shimada from Lake Ikehara on April 22, 2003, on a swimbait.

 

My personal take on this is that this bass was caught on live bait as first stated and when the angler suddenly realized what was happening, and being sponsored by Deps lures, he decided to change his story just a little bit.

 

This bass will most likely be certified as a tie at a minimum by the IGFA, but I would not take any bets that it will stand for 77 years as did Perry's record!! I think that as soon as the spring arrives in California in 2010, you will see a new world record largemouth come from Lake Dixon, most likely by Mike Long, Mac Wheatly, or Jed Dickerson.

 

In the meantime, we will just have to wait and see how all this turns out. All the most recent photographs and videos of this bass are available at Delaware Trophy Bass website at http://delawaretrophybass.com
