Hi everyone!!
I am wondering if you could take a few minutes to help me out. I am currently attempting to reconstruct total fisheries catch from Irish waters from 1950-present. The issue is that current official records only report total 'landings' and this does not incorporate estimates of discarding, IUU landings and recreational catch. This is a HUGE task and the finished database WILL NOT be perfect - but it will be BETTER than what we currently have, which are records that do not incorporate these substantial additional contibutors to overall fish mortality. To learn more about this overall project which involves the reconstruction of global catches, visit the 'Sea around Us Project' webpage at
http://www.seaaroundus.org/ So - for Ireland, recreational catch has been one of the hardest components to reconstruct. Practically no records or reports exist with useful quantitative data. Thus, to help me in creating anchor points for data estimation, if you have 5 minutes to spare could you please answer the following four questions? Thanks so much!!
1) Within the last 12 months, what was the (approximate) maximum total weight of fish that you (as an individual) caught and retained (didn’t release) on any one day spent sea angling? If you can comment on the following, what was the maximum weight you would have brought home in a day 10 years ago? 20 years ago? 50 years ago? Eg. “On my best day fishing last year I caught and brought home 5kg of fish. 20 years ago on a good day fishing I would have brought home 7kg.”
2) Within the last 12 months, what would be the (approximate) total weight of fish caught and retained (didn’t release) on an average day spend sea angling where you were successful in catching fish? If you can comment on the following, what was the average weight you would have brought home about 10 years ago? 20 years ago? 50 years ago? Eg. “On average, on days I caught fish last year, I brought home about 1kg of fish. 10 years ago, on average I would have brought home 3kg.”
3) Within the last 12 months, what (approximate) percentage of days spent sea angling did you catch and retain fish? If you can comment on the following, what percentage of days did you catch fish 10 years ago? 20 years ago? 50 years ago? Eg. “25% of the days I went fishing last year I brought home fish, 10 years ago I would have caught fish on 75% of the days I went fishing.”
4) What percentage of the total weight of fish that you caught and retained within the last 12 months were any of the following (must add up to 100% and putting 0% for any of the listed varieties is fine:
Cod:
Pollack (white pollack):
Coley (saithe, black Pollack):
Plaice:
Black sole:
Lemon sole:
Dab:
Witch:
Brill:
Turbot:
Dogfish:
Ray/skate (specify species if possible):
Conger:
Whiting:
Haddock:
Bass:
Sea trout:
Common eel:
Wrasse:
Halibut:
Hake:
Spurdog:
Porbeagle:
Other (specify):
If you are able to comment, would your answers have been the same in relation your experience fishing 10 years ago? 20 years ago? 50 years ago? If not, how would it have been different?
Thanks so much for your time, it is much, much appreciated!
Kindest regards,
Dana Miller
