Beavering away in the background.......

I would love to see the calculation formula and the raw data.

There is more than one way to arrive at a expolated number from a bunch of random stats.

Picked up on that too! I want to give that PDF a darn good read before I comment further!

Yep, estimated and extrapolated from a 12-month survey of boat-based recreational fishing in the West Coast Bioregion (Augusta to Kalbarri) of Western Australia was conducted at boat ramps between 1st July 2005 and 30th June 2006.



During the survey a total of 15,999 boat crews were interviewed, of which 13,185 (82%) had been undertaking some form of fishing activity and, of these, 10,382 (or 79%) of fishing boat crews had been ocean line fishing.



The total annual recreational boatbased fishing effort for the West Coast Bioregion was estimated to be 1,557,000 fisher hours , which is a 15.5% increase in nominal fishing effort (i.e. this does not include increased efficiencies generated by technological improvements) compared to a similar survey conducted on the West Coast Bioregion in 1996/97.



Read the paper for more details about how they collected and analysed the data.



Like it or not, agree with the figures or not, agree with the analysis and interpretation or not, this data is the best available.



Does anyone think they have any BETTER DATA they'd like to put up which has come from surveys of as many people actually out boat fishing???



And if you don't like anything about this, think about what you can do about it.

Well, I know DoF are advertising for people - I'll be putting my hand in! So will be endeavouring to do something about that!

Any chance of finding out what the pro's catch was? just to compare.

Dont think thats the answer how about halving the pro's catch I mean half the fish in perth isn't caught in that bio region or even the wa state as a whole. And are those figures correct I mean 4052 Blowfish kept come on officer

I knew a few cray boat opperators (no region given) that would after the last pot go SMASH alot of fish on board(ESTIMATED TONS)!!!! Couldn't they have waited for 10 years after this was stopped before doing any HMM HMM survey before screwing with a great Australian past time and hobby of the general public!!! BLOODY POLLIES!!!!!!! Mind you the rec tally would have been higher due to the amount of fish LEFT in the ocean!! Does anybody know if JON owns a fish store!

ALWAYS TIME FOR FISHIN' 

Yeah, someone was keeping 4% of the blowies...probably had problems with the neighbour's dog...and I find it hard to believe that nearly 3 times more salmon were caught in the metro area than the southern zone? Oh, hang on, that was that really good year for salmon....in which case, I'd have thought more than 12 tonnes? 

There's LOTS of info in the State of Fisheries Report http://www.fish.wa.gov.au/docs/sof/index.php about the commercial catch. Such a pity that so much of the info only covers catches up to 2005/6 with just the odd snippet of later info.



Fisheries Research Report 177  http://www.fish.wa.gov.au/docs/frr/frr177/index.php?0706  It really is worth a read to answer some of the questions and comments raised here.

Dhu fish take 186,000kg, say the average size Dhui would be 10kg that would be roughly 18,600 Dhui's per year which is roughly 360 Dhui's per week??? Do you think that would be about right??

Read through that article - I'm no boffin head but no slough either - pretty heavy mathematically going - so many percentages of percentages or estimates. Out of respect for those involved, a good effort, for my money though, I'd still like to see a tag system. BUT, then it comes back to the inevitable issues of resources.

(Colin 2 - Co-founding member of the prestigious Colin Club)

Would be interesting to know the amount of boat ramps on the west coast? It's just a rough average, would be intresting to know if the fisheries do know what the average size fish would be caught?? Then we would have a better idea of how many fish?

Going by what I've seen caught by people and what comes in at fishing comps the average would have to be around the 10kg mark give or take a kilo?

Average 715 Dhui's per week. HMMM

Even though the questionnaire (page 27) has a question about the species targeted, it's a great pity that there's not more data in this report such as:-



What people were fishing for and what they caught, and how many people surveyed actually had their bag limits of the various species, etc. That data would give some real info on the effect of reducing bag limits, selective bans on species, etc.



Think about this....



Dhufish caught: West Coast total 35,222 Weight 186 tonnes = average 5.28kg



At that average weight, the 58 tonnes of Metro number of Dhufish = about 11,000 fish = about 210 per week.



Target is to cut that Dhufish catch by 50%, so about 5,500 Dhufish can be caught in Metro each year in future.



If there were no closed seasons, that would average only about 105 Dhufish can be caught in Metro per week at that same average weight of 5.28 kg.



With a 3 month closed season, that increases to 141 per week during the 39 week open period.



With a 4 month closed season, that increases to 162 per week during the 34 week open period.

1: person works 6 days a week

2: weather on that 1 day off is crap (like most of the time on the weekend)

3: missus says you have to spend time with your family

4: Ah we'll leave it at that

So can you get  your calculator and tell me how many kilos of fish I will catch in a year!!  Terry "I DON'T THINK SO"

I think some people are playing with more than a calculator!!!!!  And there playing with MY HOBBY(stress relief)(family feeds).
