Discovery News reports that Horse Shoe Crabs in the east coast of America are declining and it is also affecting the larger animals that prey on them. Overfishing was previously thought to be the main cause but now a new study in the journal Molecular Biology suggests that climate change may also play a significant role. Scientists suspect that rising sea levels and temperatures since the last Ice Age likely washed away huge swaths of the crabs' habitat, separating them among newly isolated regions, and setting up these communities to bottleneck.
...
King still believes human activities, such as the harvesting of horseshoe crabs as bait for American eel and whelk fisheries, play a major role in the recent crab declines, but he wants to raise awareness about climate change's potential influence. news.discovery.com/animals/climate-change-plays-unlucky-for-horseshoe-crabs.html#mkcpgn=rssnws1 |

Ah, the great decline in fisheries. Cod an endangered species. The end of the line propaganda, overfishing.....
I've heard too many bare faced lies like the one's I've highlighted above to believe one word of this tripe.
Here's an example:
Lobster landings in Orkney have been around 100 tonnes annually for the last 170 years. This years season is awesome. Huge catches. Last years total was 134 tonnes. This is perfectly in line with a 10 year cycle which seems to follow the NAO.
Another:
Cod endangered?
Rollocks.
A good friend is mate on one of the largest trawlers in the UK. He reports massive hauls of cod. 2.5 tonnes per tow. They have to keep moving area to avoid them due to lack of quota.
Yet the eco-propagandists and the media tell us we should feel guilty about having a cod & chips.
Eat pollock they say - Marine Stewardship Accredited (more green propaganda) therefore "sustainable".
More rollocks.
MSC was set up by WWF and Unilever!!!!! - who own Birds Eye. They wanted to substitute expensive cod in their fish fingers with CHEAP pollock so they invented this little scam.
And you all swallowed it hook , line and sinker!
Excuse me if I roll about the floor, laughing.

"modify" your thread title, please. It looks funny. Thanks for that - done.
But I guess these slip-ups commonly occur when you're zipping to and fro between identities? It must get tedious all this repetitive logging in and out every time you swap ID.
You are as mad as a bucket of frogs. First I was a religious nutter now I'm suffering from multiple personality disorder. If you can't reply in a reasonable tone without accusing others of 'whatever' how good is this forum going to get? |

Mr Smith
The post was about research concerning the Hores Shoe Crab on the East coat of the US and it's decline.
As much as I'm impressed by you knowledge of fish species you haven't really engaged with the topic.

I don't believe they've declined and I've shown my reasoning above.
If someone tells you they have just arrived from Mars and their Granny's a partridge, would you listen to anything else they say?

"Cod endangered?
Rollocks."
I work in Lowestoft. Almost 20% unemployment since the fishing industry died when the catches dried up.

Kiteman,
It wasn't the catches that dried up, it was the quotas - thanks to eco-pressure in the EU.
The sea is stuffed with fish.

In the late 19th century the huge shoals of pilchard disappeared from Cornish waters, too. They didn't go extinct, they just went somewhere else.

Talking of salmon, there is a dearth of them on the great Scottish rivers. I have an explanation; between Orkney and the Scottish mainland, the seals await like German night fighters - each to their alotted grid.
When the ebb tide slackens, allowing the Salmon to transit the Pentland Firth, the seals pounce. I've seen seals so engrossed in dining on a huge salmon that we can get right up to them with the boat. They lie vertical in the water chewing on the fish and spraying great pink clouds when they exhale.
Save the seal - decimate the salmon.
We rarely get it right, eh?

The parents of my pupils would disagree, and they are the ones who captained and crewed the fleet.
Have you seen what trawling does to the sea bed?
