Trout Vs Yabbies

popeye

O.K who wins - I have got some 100gm yabbies in the bottom of my fish tank (2000l) and want to put some trout in. Are the yabbies going to eat - or be eaten! Should I remove the yabbies (they are expendable) before putting the trout in??

Well if you are hoping that the yabbies will clean up after the trout hence putting them together, have a look at this thread.

Not sure if it works, but I am considering trying it at some stage after my system has cycled.

In regards to who gets eaten, you might need to wait for someone more experienced to answer.

Depends on the size of the fish. I threw 150 mouth size yabbies into the pool and the silvers cleaned them up in no time. :shock:

Yabbies will loose 100%

agreed OBO yabbies don't stand a chance, I have yabbies in seperate tank, put 2 koonaks in with trout well put them in before trout arrived, haven't seen them since trout have been in, was hides in trout tank but hides are empty, got some yabbies from rick, he through a smaller yabbie in his trout tank, was gone before it hit the water, trout could be spotted swimming around with claws hanging out of it's mouth, you should remove the yabbies if you want a feed :lol:

the yabbies won't touch the trout

Reading over my post, I realised I was not too specific about what I was referring to. It is the plastic boxes & cages in that thread as some others have posted where you can put the yabbies into. They will protect the yabbies plus the yabbies can feed off the food that has sunk to the bottom (hopefully), but you might need to supplement them with some other food as well.

Creative1 posted this pic (Below) in another thread, ok for marron but you still should have a hide, with yabbies it will be like Thunder Dome (Mad Max for those who have NFI what I am talking about :roll:

) only 1 will be left standing, yabbies and koonaks are far to aggressive

the good thing is that feeding your trout on yabbies is they will have that nice orange colour to there flesh and tast supurbe!

Apologies up front as this is a little off topic;

In Western Australia, it is my understanding that we don't need a licence to catch yabbies, koonacs, gilgies etc with an opera house style trap. Is this correct ? Can't find anything on the Fisheries WA site that says I do.

Nigel not sure on that, I think you still need a fishing license, you actually need a license to catch Red Fin that you're not meant to throw back, you don't need a license to catch them in farm dams. I certainly know with marron you can catch them on farm but can be fined for transporting them from farm to beer shed in town :oops:

without a fishing license, didn't quite get fined but got 10 pages of paperwork with my warning, did find below quote on fish WA, doesn't indicate if you need a license, but still sure you need a license to fish in any river or waterway, think their only $25 anyhow, better safe than sorry, may need a trip to Narrogin, plenty of dams here :wink:

What you can do

If you catch a yabbie, keep it. There are no bag limits so you can eat or freeze them. Don't use them for live bait (use gilgies instead). Don't release them into rivers, lakes or dams.

only other info I have found doesn't indicate a license is required in WA

Where can I get a recreational fishing licence?
An application for a fishing licence can be made on-line through the Department of Primary Industries or Fisheries websites (see links below) or from their authorised agents. A national code of practice has also been developed by Recfish Australia for recreational fishermen (http://www.recfish.com.au) and they have a very informative website.
QLD - a Stock Impoundment Permit (SIP) is required for about 33 dams in Qld. For the Baroon Pocket Dam, Hinz Dam, North Pine Dam and Storm King Dam a Council Permit to fish in those dams is required. For the SIP you only need one permit per couple (defacto or married) and if you are under 18 years of age you don’t need one at all. Available on line at DPI & F, by phone (13 13 04) and small business outlets listed on their website. From March 2009 there will be changes to the Recreational Fishing Rules & Regulations for Queensland so for more details check here
Before you go fishing also check where the marine park boundaries are:- Qld Parks & Wildlife Service – Environmental Protection Agency (http://www.epa.qld.gov.au) and the Great Barrier Reef Marine Part Authority (http://www.gbrmpa.gov.au).
NSW – by telephone 1300 369 365 (Visa and Mastercard only) or apply on line at DPI, DPI Fisheries Offices, or one their Gold agents or NSW listed agents. In New South Wales you must obtain a fishing licence to fish in saltwater or freshwater anywhere in NSW. See their website for full details.
ACT – you do not require a recreational fishing licence in the ACT but regulations do apply and these can be view on the Department of Territory and Municipal Services website.
VIC – apply on-line at DPI, one of the many DPI offices or business outlets in Victoria as listed on their website. A Recreational Fishing Licence (RFL) is required when taking any species of fish by line fishing, bait collection, gathering shellfish, prawning, yabby fishing and spear fishing. See their website for full particulars.
TAS – apply on line at DPI & Water or one of its 120 agents including major fishing tackle and sports stores. For those who wish to renew their licence and know their client number you can call 1300 720 647 [or (03) 6224 1931 for callers outside Tasmania. In Tasmania you do not need a licence for sea fishing with a rod and line but for angling in most inland waters an Inland Fisheries Angling Licence is required. See their website for full particulars.
SA – a licence to fish recreationally with rods and handlines in South Australia is not required. See PIRSA Fisheries website for regulations relating to permitted devices, closed areas and bag limits. Recreational fishers are not permitted to sell or trade their catch. See their website for full particulars.
WA – apply at the Department of Fisheries and all Australia Post outlets. Recreational fishing in Western Australia is managed within four biological regions and each region has fishing rules and regulations to suit the regional ecology, fishing pressure and mix of species. Some new recreational fishing rules were introduced from January 2009. See their website for further details as well as maps of the biological regions.
NT – No fishing licence is required for recreational fishing in the Northern Territory but none of the catch can be sold or bartered. In Kakadu National Park some additional fishing controls apply (Department of Regional Development, Primary Industry, Fisheries and Resources). There is also a requirement to obtain a permit to enter Aboriginal land and adjoining waters. For these areas enquires should be directed to the Northern Land Council (NLC) on 1800 645 299 or http://www.nlc.org.au. In NT they have a ‘possession limit’ rather than a boat, trip or daily limit. The possession limit is the number of fish a person may have in their possession at any one time (other than at the permanent place of residence). For full information see the DPIFM website.

Thanks Nocky

Looks like a grey area. I work in the city so I think I'll go for a trot up the Terrace and run it past 'em face to face.

I'll post up the outcome.

Nocky

ask a few mates and still NFI nigel as we don't catch them in waterways, best check it out in Perth, will be interesting to see, I would be surprised if you didn't need one, you almost need a license to fart these days

ivansng

Sorry to hijack, but I thought that it might be appropriate.

How about goldfishes vs yabbies??

Nocky

Ivan have a small yabbie in a small indoor aquarium with 2 small goldies and yabbie has a go at the goldies but they are too quick ATM, but big goldies will eat small yabbies, yabbies actually grab hold of my mussels and drag them around the tank, they are violent little buggers

chillidude

OK - I've been to the Fisheries Dept - discovered it is in the building next door.

As I was putting my query to the receptionist there was an older guy talking to someone else. He stepped in to answer my question. I don't know who he was but he was in a suit and gave the impression of being fairly senior.

Anyway, he took me over and started going through the identification folder showing me the difference between marron and gilgies. This is nothing new to me, but I figured he was on a roll so I'd just keep it to myself.

The outcome was that we (myself & the kids) do not need a licence to catch yabbies, gilgies or koonacs ! Cool ! He did say that if any inspectors are around they will come over to check on what I'm doing and that I better not have any "accidental" marron in the bucket.
