That does not sound good to me at all

Banning night time scooping? its been one of my favourite things to do for yearsCry

No females until after march 1 is stupid the females outnumber the males easily so what do they want to do, make that gap even bigger by people only keeping the males. Rules made by people who have no clue. Yell

i like the ban, not sure about the night time scooping tho

if it were upto me, the crabbing in mandurah should be banned until jan 1st. Crabs down there arent big enough until then. they need a chance to grow

you could keep the ban

you could keep the ban untill jan 1st but these new fees we are going to pay to (free) fishing shouldnt that be going to more fisheries and boats to patrol the waters to stop these people taken more than what they need ie;woodmans point 20+pinkies in one day any way you will probely find we should have big crabs come through this yr with all the rain we have had just remember people only take what you need

Fingers crossed the season is better than last year.Yes hopefully the rain will help, and it will warm up a bit earlier this year. I think the ban is a great idea. Give them a chance to grow.

mandurah has always been a popular spot for crabs and unfortunately the numbers of crabs over the years have copped a beating, only taking the male crabs imo has had a detrimental effect by reducing the population over time as it has left less males to breed . i believe it need a complete ban on crab fishing in mandurah for 1 year to give the crabs a chance to recover from being overfished for so many years. you get most people only taking what they need but you do get a lot taking what they want and in many cases way too many.i have only been crabbing a few times but i have noticed the stock reduction dramatically.

Consultation and Research Data for proposed Mandurah Crab Closur

Sun, 2009-09-20 09:08

Consultation and Research Data for proposed Mandurah Crab Closure



There have been media reports about "Public consultation" on a proposed extension of the Mandurah crab closure. See http://www.westernangler.com.au/forum/fb.asp?m=228578 for some background



The time frame is very short (wanted by 25 September) without giving the public access to the research information they need to give properly informed comments.



OK, so here's access to the letter to stakeholders and the research information.



http://www.recfishwest.org.au/PeelHarveyCrab2009.htm



You will note the heading "Research Data Regarding A Seasonal Crabbing Closure In Area II Of The West Coast Estuarine Fishery (Peel-Harvey Estuary)" which immediately had me thinking "OK, does this mean they have decided the answer, and here's the justification?"



I would have much preferred it to be "Research Data Regarding OPTIONS FOR MANAGING Crabbing In Area II Of The West Coast Estuarine Fishery (Peel-Harvey Estuary)"



Now you know. Go to it. Here's a chance for forum readers to put in informed comments. Use it, please



Comments to Recfishwest, please, PO Box 34, North Beach, WA 6920,  9246 3366, Email

Russ,

I hear what your saying but i dont totally agree with the the numbers declining due to all the males being taken.

Last year the number of females caught still didnt out weigh the number of males caught (my experience).

But the male sizes were very small, it used to eb a few eyars ago you didnt need to leasure any crbs as you could tell they were big enough. But the last couple years this has changed, sizes have dropped dramatically. If only the crabs were the size fo the swan blue's.....

size

Sun, 2009-09-20 10:51

Size was down last year and the amount of males. We always go snorkelling for them so you see how many are around. The amount of small females i feel increased last season for sure..there were everywhere.

The crab season before was loaded with crabs.Lots of big males, and you got your bag limit easy each trip. Not sure if it had something to do with rain, later warmer temps last year, but something is happening with the numbers.

Im not keen on a total ban. As the crabbing industry means alot to the Mandurah local economy. Im all for a later season for us and the pros.

ive been crabbing down

Sun, 2009-09-20 16:29

ive been crabbing down mandurah for over 16 17 yrs and i can remember going down there in october catching big crabs and lots of them now its drop right away to minimal crabs are just size and not very full of meat the females are most of them are just under size and were not catching them till mid jan now maybe this is just not from people reaping the crabs maybee it has something to do with mandurah extending its suburbs reclaiming water must have something to do with crabs not growing to full size and the amount coming in every yr, have a look at mandurah 10 15 yrs ago how small it was and not much water was reclaimed now have a look at alll the canels with homes on them its not good for the system and how many times does the water quality go to shit because there is not a good system to clean the water out when they opened dawsville cut it was bloody good fishing crabbing but now with alll these new homes on reclaimed water the flushing out of the river isnt as good the water is always milky colour its not good so in saying all this i think its not just the people fishing it every thing else comes into it maybe they need a new flushing system what do you people think i think im on the right track

it probably isn't helping

Sun, 2009-09-20 17:04

but IMO the lack of policing, overly generous bag limits and greater number of people targetting them because of locality/improved access to the area are easily the biggest issues.

FACT - the Dawesville

Sun, 2009-09-20 17:00

FACT - the Dawesville Channel openned in April 1994 ! Fact - Mandurah is one of the fastest growing Regional CITIES in Australia. Fact - the fishery has declined elsewhere on the West Coast Bioregion of past recent years. How much is attrbutable to each cause is at this stage unkonwn by DoF "researchers". I have grown up in Mandurah and fished the Peel-Harvey for many years and personally know several pros. If closing it will help, then sure do it. But will it help??

Recfishwest has sent its response to the proposed extended closure of the Peel Harvey crab fishery. http://www.recfishwest.org.au/PeelHarveyCrab2009.htm

Re Proposed management of the Peel-Harvey Estuary Crab Fishery for 2009/10



Thank you for your letter requesting Recfishwest's comment on reviewing management arrangements for the Peel-Harvey Estuary Crab Fishery for 2009/10.



The Recfishwest Board has not had enough time to fully discuss this proposal. Nevertheless, we believe that changes to the current management arrangements for the blue swimmer crab fishery in the Peel-Harvey Estuary require more thorough consideration than ad hoc changes to the closure time.



Based on the information provided in the preliminary report, Recfishwest sees little evidence that a change to the current September-October closure would make a significant contribution to the long term management of this important fishery.



The highly responsive nature of the blue swimmer crab population to variable environmental conditions is acknowledged by the Department and is clearly evident in the data presented in the preliminary report. While Recfishwest supports the protection of berried females and sees a benefit in protecting pre-spawning females, there is no clear evidence that justifies extending the closure into November.



For instance, female crabs appear in low numbers within the pot lifts of November during the 2007/09 survey period yet no females were present in the pot lifts during the same period of 1998/2001. A November closure would have protected a small proportion of females during 2007 to 2009 but would have provided no benefit in 1999 to 2001. Indeed, if the protection of pre-spawning females is a priority, then consideration should be given to a complete closure of the Peel-Harvey Estuary Crab Fishery during winter.



More evidence is also needed with respect to the rationale "to reduce the catch of undersize crabs" based solely on the percentage of undersize crabs being 76% during the monitoring surveys of 2007-2009. For example, the mean percentage of undersize crabs in the monitoring surveys of 1999-2001 was 40% with only an 18% undersize proportion in November 2000. It appears that "a noticeable increase in the number of recreational fishers caught with undersize crabs during this period" is a matter of education and compliance rather than an issue of sustainability in a highly variable recruitment fishery.



The blue swimmer crab fishery is one of the most important recreational fisheries in Western Australia, particularly because much of the resource is so close to major population centres. It is shared with a sizable commercial fishery and competition between these sectors is an important issue. There have been two lengthy negotiations between the sectors resulting in agreements. One of these was in Geographe Bay and the other in Cockburn Sound. The first of these was overturned by a political decision and the second was not supported by the Department of Fisheries. This was followed by a large reduction in recreational bag limits affecting the whole South West recreational blue swimmer crab fishery without any apparent adjustment of commercial catch. Recfishwest believes that it is time that the blue swimmer crab fishery is brought under proper integrated fisheries management with managed allocations to major sectors.



In light of the recently introduced seasonal closure and a recent 50% reduction in recreational bag and boat limits (September 2007), for which there is little data on its impact on the recreational fishery, Recfishwest cannot support the proposed management change for the Peel-Harvey Estuary Crab Fishery. Recfishwest believes that more comprehensive data sets on the catches, biology and ecology of this exploited stock are required to provide a background for proper integrated management of this fishery



Recfishwest believes that the reopening of Cockburn Sound to crab fishing will shift some pressure away from the Peel-Harvey system over the summer months of 2009/10.



Recfishwest has met with members of the commercial fishing association to discuss future resource sharing and the opportunity to develop a MOU arrangement for the Peel-Harvey Estuary Crab Fishery for the 2010/11 season. Recfishwest supports the proactive proposal to introduce escape gaps on commercial fishing pots to minimise handling of undersize animals. We have also discussed the need to reduce the commercial catch of pre-spawn cobbler and a variety of environmental issues where we share common concerns.

Yours sincerely,



Andrew Rowland, Regional Policy Officer
