Please explain the WRL migration
Submitted by randall df223 on Sat, 2014-12-13 08:08
I read a lot on here about the "whites" walking.... and i think i understand that they start the season in shallow and then walk out deeper as the season progresses?
Can someone knowledgeable in the life cycle of WRL please explain it in 200 words or less?
Do the eggs hatch in close and they stay inshore for a number of years before walking? are they referred to whites because they have shed their shells? How often do they shed their shells? How many times in their life cycle do they walk? is it just a one off?
very interested to understand them better.
Cheers guys.

LOL 200 words.......
For starters there is no differance between reds and whites ( just the colour ), and yes the are a lighter colour due to them molting.
More to come when I have a bit more time.

crays
females throw eggs when very dark brown color. eggs will hatch and usually move out deep with current. When they are pirolous (not sure of spelling). About 1cm long and transparent they make their way back to shallower water and reside in hokes ledges wgerever they can be safe. Adter a 4to 5 year cyle of growth and numerous malts they reach market or capture size of 76mm on carapace.
Whites are just tge new shell under old shelk and are white as time goes n shell hardensit turns red but some stay cream color and reside on coral also known as ciral crays. The whites will migrate from shallower to deeper water as they harden their shells. Some settle some migrate to the shelf. From lano nth theyll make their way to shelf. Double gearing out of leeman in 110fthm in the mud n getting hay bail pots!
The crays migrate back up top of shelf n settle n when thereis an overflow of crays on coral you will see them come into shallows. Where they go from 60mile nth of kalvarri no one knws but hve been chased in 120fthm 90miles nth of kalbarri them Bit ovr 200 words but heyI

How Deep?
How deep do WRL go?
Everybody seems to be putting their pots in the shallow waters near Garden Island and the 5 Fathom bank, but is it worth putting a pot in 50m of water? My thoughts are that at the moment with the whites walking so the shallow water is better, but later in the season it's better to try the deeper waters.
Like Randall I'm interested in knowing more about WRL.
Thanks for all of the above info, I found it very interesting to read.

gutters
whites when they march in deeper water, well up here n leeman off shelf will follow gutters or highways. Every year they will use those same highways to migrate.
Out at big bank youwould set your gear in gutters either e to w or n to s.
Sometimes a pot half a fathom inside or outside would get nothing and the ones in the middle would come up milk bottles.
Saw heaps of that off the shelf in leeman.
Look for sand moundsin deeper water. The trench would be a main highway for them down there if your keen to pull a pot that deep but youd have to double or triple gear just to hold bottom!!
