Sport Relief challenge yacht Dongfeng rounds Land's End - NW Storm 10 on the way!

The current wind off the Lizard is around 27 knots...

just as well as six hours later it will be well over 60 knots!

Update at 17:43 as the skipper keeps the crew on their toes with another change of course running before the wind...

Update at 17:30 - a big gybe and heading for the Lizard - don't get too close guys the overfalls in the shallow water deep off the Lizard are just not nice - more like #HellOnHighSeas...

Thirty four hours after leaving Belfast the Dongfeng has rounded Land's End - and after making a steady 10 knots for much of the time she is now making up to 17 knots! - not quite quick enough to catch sight of MFV Algrie heading home for Newlyn...

and with a Nor'westerly 10 forecast she might make even more speed - let's hope the celebrity crew including @missAlexJones from the @BBCTheOneShow enjoy the ride.

#HellOnHighSeas heads for Land's End!

Sixty five feet of pure ocean racing yacht with precious little wind provides two intrepid but nervous novice celebrity sailors with a gentle start to this year's #HellOnHighSeas BBC One Show celebrity Sports Relief Challenge...

as they head south from Belfast, and the leg of their semi-circumnavigation of the UK - the weather having dictated that they avoid the Northerly route around Scotland to avoid putting the two complete novices through too much danger!

With around 280 miles to go and an average speed of 10 knots the boat should sight the Longships around 10pm tomorrow evening...

Wind forecast from EarthNull.orghttp://bit.ly/1R3eI6K

when they will have a vicious little depression giving them a serious push from behind as they round the corner and head east - stay tuned to their progress using VesselTracker AIS!

Monday's morning blues and hues.

One waning moon hangs over RNAS Culdrose and the Lizard...

while the number of merchant ships anchored off in deep water in Mount's Bay increases daily...

the view looking down over the harbour this morning...

provides a stunning view across the Bay...

as some of the smaller boats...

make their way to sea...

making her first landing for the tide, the Karen of Ladram berthed at the fish market...

while inside the market students from the Robert Smyth Academy listen attentively to Lionel givinmg the the low down on wide variety of fish ready for auction...

like these top quality monk tails - a great fish for curry dishes...

long with the big white fish landed by the Karen...

all get the once over form the Cefas team...

sampling flats from the Cornishman...

did Miss identify the fish Lionel is showing her?...

top of the price list for fish this morning will be these turbot, the fish with the rough skin (dark side) not to be confused with brill with its smooth skin...

plenty of mackerel around at the moment for the handliners...

though some of the grading terms used, like 'good small' are not necessarily the official ones...

the netter end of the market is full of big white fish like these pollack...

and big ray, again from...

the Karen...

auctioneer Olly tallies up his next lot to sell...

while the man behind the camera and Mousehole Fish, the Little Fish shop on the corner in Penzance cannot resist capturing this morning's stunning dawn light...

bathes the harbour in a golden glow...

Harbourmaster Rob Parsons carries out an early inspection alongside market boss Lionel...

ice being delivered nonchalantly 'over the shoulder' style...

while the Belgian beam trawler takes fuel ready for another trip up channel...

with a week in Cornwall that started yesterday with the Eden Project, Robert Smyth Academy Geography and Business Studies, unmissable in their tops created especially for the tour...

the fish market visit over, now assemble wide eyed from their 5am start - are now ready for the next leg of their tour which will see them take in venues on the Lizard and Falmouth later today.

The Landing Obilgation - Unintended consequences - the law of.

An international study led by The University of Queensland has found that a gradual reduction – over two decades or more – in the practice is the best way to allow a marine ecosystem to recover its natural balance.

Esther Fondo, a PhD student and the study's lead author, said a range of predator species were reliant on discarded fish – dead and alive – as a food source.

"Human activity – including rubbish dumping, game hunters discarding carcasses, and commercial fishing – returns more than seven million tonnes of discarded fish to the sea each year," said Ms Fondo, of UQ's School of Biological Sciences.

"This has significant negative impacts on the marine environment. It increases scavenger species populations to excessive levels, disrupts ecosystems and places some species at increased risk of predation.

"We looked at two scenarios—drastic and gradual banning of discards – using data from Moreton Bay near Brisbane, Australia, which is a popular site for prawn trawling," Ms Fondo said.

"Ecological modelling software simulated complex food web interactions and showed that both gradual and abrupt removal of fish discards decreased the survival of scavenger species and changed the ecosystem.

"Scavengers were able to switch to their natural prey when discards were reduced gradually over a 20-year period, but predator numbers declined when discards were abruptly banned."

Ms Fondo said the researchers recommended "gradual reduction of food discards to a minimal level".

"This would maintain the ecosystem's stability and allow species exploiting food discards to adjust to reduced food subsidies," she said.

MS Fondo said the research was timely, as the European Union was introducing methods to improve sustainability of its fisheries, including a commitment to extend the number of fish species included in the discarding ban.

Fishing discard bans currently are not being considered in Australia.

Ms Fondo said the next step in the research would be to extend computer modelling to marine ecosystems in a number of different countries.

In honour of St Piran.

To all Cornish fishermen wherever they may be.

Happy St Piran's Day one and all!
