No need to pray for a cray, just drop your pot in the right spot

Western rock lobster are very sought-after!

Not many things excite fishers like the annual rock lobster ‘whites run’.

It’s a time when metro cray fishing fires up to an outstanding level and dropping pots truly comes into its own!

Pulling in a heavy pot loaded with a feed of crays is the ultimate goal for many cray fishers and the whites run is your best opportunity to experience this.

The annual whites run is the main reason 80 per cent of all recreationally crays are caught using pots.

The whites run often occurs around late November and early December each year.

As the crays begin their annual migration to offshore waters, they provide unmatched fishing opportunities for potters.

The proximity to shore means people can head out early bag themselves some crays and be back in time for work.

The summer months are where more than half of the total recreational crays are caught!

In this article, we will provide you with a forecast ahead of the season from the puerulus settlement index the Department of Primary Industries and Regional Development (DPIRD) collects, provide answers to commonly asked questions and point you in the right direction to catching some of these super-tasty crustaceans in time for Christmas.

About 80 per cent of WA’s rec crayfish catches are in pots!

What is the 2019/20 season forecast looking like and what is the puerulus settlement index?

It appears a great season is ahead of us, the puerulus settlement for the 2015 and 2016 season is well above average.

Now what’s this puerulus settlement have to do with the cray season four years on?

Well, DPIRD developed a method to collect the puerulus which is a juvenile stage of a cray by using a specialised buoy that mimics natural algae habitat on which the juvenile crayfish like to settle.

DPIRD scientists work out the concentration for each new moon period of these settled puerulus and can then work out trends and patterns in recruitment.

This settlement information has a strong correlation with catches of crays in three to four years, once the crays have matured to a legal size.

Why are they called ‘whites’ and where are they ‘running’ to?

Good questions! A ‘white’ cray is a colloquial term applied to crays that are freshly moulted with their new soft, pale shell showing.

This is in comparison to pre-moulted crays which have a hard, dark red shell.

Juvenile crays settle along seagrass beds and rocky habitat close to shore.

Once they reach sexual maturity at about three to four years, they migrate en masse from this inshore habitat to the deeper offshore reef platforms in a north-westerly direction.

DPIRD research shows that crays can walk up to 5km a day with crays tagged at Rottnest showing up recaptured later at the Abrolhos!

That would definitely have the researchers double-checking the tag numbers!

Averaging 5km a day these offshore crays sure do move around!

OK, so it’s forecast to be a great season but the six million dollar question: when will the run actually happen?

Whilst there are multiple factors that influence exactly when the migration begins, it is generally understood that the migration will start towards the end of November and will reach full swing by the beginning of December.

The run is believed to be triggered by warming water temperatures and good catches usually continue until about Christmas time. Cooler water temps tend to delay the start of the migration.

Though this year, unlike the last, the warm water seems to have come early and crays were moulting as early as the first week of November.

How do I go about catching them?

The whites run is when potters do best.

Divers tend to be more consistent than those dropping pots across the year, but the period from late November to Christmas is when dropping pots come into its own. As crays are on the move from under their usual nearshore reef ledges, they will seek food and shelter along their migration path.

A well-set cray pot provides both of these needs. Keep dropping pots further out to sea as the migration continues, and check your pots every day during this period.

Crays can travel many kilometres a day so don’t be afraid to spread your pots out to get an idea of where good numbers of crays are each day.

Even though potters do best during the whites run there are also still plenty of divers in the water at this time so common sense needs to be used, keep a lookout for dive flags and don’t throw your old bait in the water if divers are nearby.  There are plenty of crays for everyone to enjoy during the whites run.

After crayfish hatch, they live offshore as planktonic Phyllosoma later growing to the Puerulus stage that settles in inshore waters.

What is a well-set pot?

Cray pots that are well-weighted are much harder to pull up but sit steadily on the seafloor while the swell and surge rolls back and forth. Heavy pots are also much more likely to stay put during a storm so they don’t end up tangled in the reef where they can become stuck and even detached from their ropes when the ropes rub against the reef overnight and fray.

Crays are much more likely to enter if the pot is still, any movement will mean no crays in the morning.

Pots should be set on the sand on the western side of natural habitats such as reef or weed, this way, as they migrate to the north-west, they will walk off the reef, onto the sand and find your pot sitting there ready for them.

Make sure the baits are fresh, so don’t let your bait get rotten in the basket, change it every few days at the very least.

Use something oily to get the best results, blue mackerel and orange roughy heads or the new burley bricks that are a great plastic-free alternative that are packed in cardboard ready to go in your bait basket.

A few more tips include clipping the tail of your crays as soon as possible, marking your floats clearly with your gear ID and it’s also worth marking your pots too.

You should also soak your pots before you deploy them as they’re known to bubble for at least 24 hours as the dry wood soaks up the saltwater, something that crays hate and you are unlikely to catch while they’re bubbling.

Thanks to Simon de Lestang from DPIRD for presenting this great information at the cray fishing night that was held at the Cockburn Power Boats Club.

There was a great turn-out from club members and non-members, with a huge amount of information shared over the course of the night.

Keep an eye out for club nights like these, they’re a great opportunity to meet like-minded fishers and advance your fishing knowledge. We expect this whites run, and the next, to be excellent and wish all fishers the best of luck chasing a feed of delicious WA crays for Christmas.

Things are about to get CRAY-ZY! *Video explaining new rules*

Cray pots are being dusted off from the shed, ropes are being prepared, the freezers  are stocked with bait and safety equipment is being updated, as the warmer weather brings with it what’s known as the annual ‘whites run’.

Cray fishers are well prepared this year, with knowledge in their back pocket of the season to come with healthy stocks of crayfish announced earlier in the year resulting in the opening of a 12 month season and updated rules that are simplified and practical, ensuring people’s fishing experiences are maximised.

What is the white’s run?

Late November is when it all kicks off with crays making their annual migration to offshore waters, providing excellent fishing in nearshore waters. Once it cranks up, the fishing will be superb, with many boats traditionally reporting catching their boat limit most days during this migration period and good catches usually continue until about Christmas time.

You can see the difference between the red cray (early and late season) flanked by two whites, which run from about November to January (same species, different stages of migration).

Why are they called ‘white’ crays?

A ‘white’ cray is a colloquial term applied to crays that are freshly moulted and have a soft, pale shell. This is in comparison to pre-moulted crays which have a hard, red shell. The crays are exactly the same but are at different stages of their life cycle.

How do I go about catching them?

The white’s run is when potters do best. Diving catches tend to be more consistent than potting catches across the summer, but the period from late November to Christmas is when dropping pots come into its own.

As crays are on the move from under their usual nearshore reef ledges, they will seek food and shelter along their migration path. A cray pot provides both of these needs. Pots should be set on the sand on the western side of natural habitats such as reef or weed. Keep dropping pots further out to sea as the migration continues, and check your pots every day during this period.

Crays can travel many kilometres a day so don’t be afraid to spread your pots out to get an idea of where good numbers of crays are each day. Crays love fresh bait, so don’t let your bait get rotten in the basket, change it every few days at the very least.

Perhaps the most important aspect to remember when dropping pots is to make them heavy. Any movement on the bottom will result in no crays the next morning, so make sure you use plenty of weight.

Diving is the other main way of catching crayfish. Most divers search under rock ledges to find the crays and then either use a cray snare or a gloved hand to grab their quarry.

Top Tips for Potting for Crayfish

How do I rig my pots to ensure they comply with the new rules?

Recreational lobster pots will now have to be rigged in a similar fashion to commercial pots to mitigate the potential risk of interaction with migrating whales.

Any pot using more than 20m of rope will be required to hold the top half of the rope vertically in the water column.  This can be achieved by using sinking rope on the top half of the pot rope, or by simply attaching a weight such as a fishing sinker half way down the rope.  Additionally, a maximum of two floats will apply on recreational pots.

The Annual ‘Whites Run’ – Time to get Fishing!

There’s a handful of events in society that each year create a state of extreme excitement. For some, it’s Boxing Day sales, the Melbourne Cup or the AFL Grand Final, but for about 55,000 West Aussie fishers, it’s the annual migration of Western Rock Lobster (crays), known locally as the ‘whites run’.

It’s this time in late November and early December that crays begin their annual migration to offshore waters providing excellent fishing in nearshore areas.

In this article, we will provide you with some answers to commonly asked questions as well and help you head in the right direction to catch some of these tasty morsels.
