Fishermen and the Great White Shark Attack

[sleepy]

Good Morning. And a lovely day it is, fishing on the pier at Manhattan Beach. The sun is shining, the water is warm, and the fish are biting.
So grab a brew and enjoy the day!

This is the news report of the incident:

funny (well, not really), i just watched a columbo episode in which ricardo montalban played an aging bullfighter who used an agitated bull to kill his murder victim.


guess it's all fun and games to these yahoos.

 

[sleepy]

Yeah, the brothers' grim, but the report states that the shark was tangled on a fisherman's hook and line and it's not clear whether the fisherman was one of the people in the video. Some folks saw this, pointing out that fishing for Great Whites is illegal as they are on the endangered list.
They suggested having them arrested, thinking they were the fisherman. But at any rate, the authorities have declared the attack an accident.

The fisherman himself was reported as hooking the shark by accident.
He was fishing for legal catch, or so he said.

 

[Isaac Sauvage]

just for me, the guffawing and the casual nature of their response came off as kind of creepy. i would have been hollering a lot louder than that and probably going down and waving those swimmers in.


btw, there was an interesting story in the news today about whales being traffic-directors of the sea, so to speak. some species are making a comeback, and they have the potent talent of consuming catches in one place and then seeding other areas far away with their emissions (plumes), feeding plankton and such and stimulating fish populations.

apparently some people don't understand this process too well, and think that the whales are competing for fish harvests. others, such as the japanese, more or less want to catch them all and turn them in to whale sushi... which is generally pretty toxic from what i've read.

this is why I learned never to go into any body of water
where I ain't the top of the food chain!

How does the air work for you then? :)

Really chances are you're more unlucky if you win the lotto, yes that is winning and/or then losing it all.

Hell I'd rather take my chances..

Leave them sharks alone swim with them if you can...

 

[sleepy]

Yep. Very creepy people.

Hey faralos, I'm pretty sure the sharks stay away from the shoreline. As long as you're less than 10 ft. deep with any riptide, you are likely safe since sharks don't like sand in their mouths, and also, they don't tend to approach the shoreline since they are unable to swim backwards. When they get beached or stuck and can't move forward, they risk going into shock and dying. They have to be able to move forward in order to breathe. Or so I've read.

The victim was swimming in deep water. off the far end of the pier.

I Fish and swim along the mid-Atlantic. Both night and day. I had a close encounter with a Manta Ray in the surf off Kitty Hawk N.C. I was fascinated by that huge black thing as we checked each other out. When I turned around every one had cleared the ocean. I admit to a cavalier attitude towards swimming in the ocean and love swimming at night. Even more when plankton sparkle the water around us on warm Summer nights. If something truly wants me for dinner I figure I"m just as slow in the water 24/7. My favorite notion from the Bible is God granting man dominion over all plants and animals. Human is not supposed to be their food of choice. I always see us at the top of the food chain.

 

[sleepy]

I don't think I'd try eating shark though. Has anyone else?

 

[Coil_Smoke]

Several years (or was it decades?) ago Shark became available at the local markets. At first I thought it a decent low priced sub for Swordfish. Best hot off the BBQ. Soon the sponge like porosity of Shark flesh became a bit off-putting. Now the thought of having Shark causes a wrong way going contraction in my stomach ...

 

[sleepy]

Yeah! Nooo!

 

[Isaac Sauvage]

sharks lack swim bladders, so yea... they have to keep swimming or typically sink like a stone, unable to breath. it is the action of the water being pumped across their gills that allows them to do their O2 / CO2 exchange. although i know there are a couple exceptions IIRC. i've seen some species that are able to rest on the sandy bottom for extended periods.

fun fact: we humans still have our gills at a certain stage of development... then they get reabsorbed.


anyway, i can't remember eating shark. it likely would have been as shark fin soup at a chinese restaurant if so. in fact the chinese have decimated certain shark populations. IIRC they typically catch the fish, slice off the fins, and then through the animal back in to the sea to be eaten alive by whatever.

man is both top of the chain and bottom of the chain to me.

 

[StevOz]

Sharks can rest as you say, though only in a current. I have eaten shark and it is rather tasty as good as any fish from the old fish 'n' chips shops, often called flake. That said only smaller sharks are any good for food the larger one have to much ammonia.

 

[sleepy]

I believe lemon sharks are the exception. I saw one in an aquarium just resting on the bottom of the tank watching his victim on the other side. The victim had a half moon bite missing from its underside tail and was on the other side of the tank, frantically trying to hide. This was at Los Angeles Union Station (the main train station). I think I've mentioned this before in another thread. Why on Earth the city crew mixed the tropical fish in a tank with a lemon shark is very stupid.

You may have seen Union Station before, if you have ever watched a movie from here that has looong corridors and/or a classic 30's main entrance with chandeliers. The square tunnel-like corridors are unbelievably looong, like walking down a Flood Control channel. If you don't know what a flood control channel is, that concrete "river bed" that was used in T2 for the motorcycle chase is one. That flood control structure is the main flood control channel in Los Angeles and is used frequently in films. The Storm Drain Covers on the pipes that drain the rain runoff into this structure are about 1 yard in diameter and always did look like a big circle with a pair of cat ears on top. Back in the 1950's and ever since, some of the locals, or somebody, began painting cat faces on these lids, visible from the freeways. Artist Leo Limon has been keeping the faces maintained since the 1980's, but I remember seeing them in the late 1950's.

This is the Wikipedia section on Union Station in pop culture (movies):

Did someone say...

http://en.wikipedia.org/wiki/Wobbegong


Now they are exceptional eating no matter the size, that said they are now a protected species here...

 

[faralos]

found this:It was once believed that all sharks had to swim constantly in order to breathe
and could not sleep for more than a few minutes at a time. Oxygen-rich water flows through the gills during movement
allowing the shark to breathe. While some species of sharks do need to swim constantly,
this is not true for all sharks. Some sharks such as the nurse shark have spiracles
that force water across their gills allowing for stationary rest.
Sharks do not sleep like humans do, but instead have active and restful periods.

 

[Coil_Smoke]

Is it true sharks excrete their metabolic waste through their skin? Do other large predatory/game fish do that too? I used to love Swordfish including it's crispy skin fresh out from under the broiler. I hope they don't piss out their skin like Sharks. Then I learned all those large fish test high in Mercury. Salmon are said to be low in Mercury and I like Ocean Perch but that 'Fuk-YOU-Shima' abomination is going to ruin that any day now.

no, there is at least one species that can pump water across its gills at rest on the sandy floor. been awhile, on tablet now... let me get back to this.

EDIT, ok faralos got it... nurse shark sounds correct. coilsmoke let me take a crack later at ur Q's.

like amphibians, say? anyway, i double-checked on WP just now and such does NOT appear to be the case, metabolic-waste-wise.

IIRC scandinavians (norwegians maybe) make a weird delicacy out of fermented sharks and shark-like fish... specifically high in ammonia. i think it's called ludafisk or something like that. crazy. i first heard about it on the feldman show, where bill lives now.

anyway, yea... tuna was already dicey as an apex fish, but now it's probably best to avoid altogether, post-fukushima. at this point, all apex predators should probably be avoided... not that we typically eat polar bears and orcas, etc... but these poor animals are basically serving as toxic waste dumps for us humans, indirectly.

consumable tuna is a class of large fish, not any one species, BTW.

 

[Coil_Smoke]

Got Soylent Green...?

Thanks for the info...I just have a vague memory about that excretory thing. I now think it may be urban legend. That Soy Green looks better every day !

 

[Isaac Sauvage]

haha, i should watch that movie one day. OTOH having read the book ("make room, make room") i'm feeling a might lazy.


anyway, i'll try to look in to this further. i think it could be said that mammals excrete metabolic waste through the act of sweating, so it's not such a left field-thing in general. insects do gas exchange through spiracles, for example.

on a slight side note, there are also animals, such as desert lizards and such, that concentrate sodium levels (while retaining precious water) so as to pee a supersaturated salt solution.


yes i'm crazy about animals... hard to stop once i get started!

Hmmm, the movie appears to differ from the book.
Things like setting up the film's climax and the M.O. which were not in the book and is an apparent variation of the climax from the original "Planet of the Apes" film (1968). Heston must have loved that one, since he did it twice.

if shockman were here he might administer a long rant upon the matter.

 

[sleepy]

They did the same thing with Planet of the Apes. The book had the astronauts return to "their planet Earth", only to be greeted by the ruling Apes. The movie of course differed, though the film's climax was originally created at the time of the book, around 1960. The book's version was the "also-ran choice". Don't ask me how I know that.
Like the love affair between the marine biologist and the sheriff's wife in the novel, "Jaws". It was just trash added for the book by the scribe. The original story was the film version.

The current reboot totally dismisses the point of the original story, man's nuclear folly and pointless society, by empowering the Apes in the human era, but I accept that as a separate fork...I guess...
