The IkiJime Tool Extreme app helps anglers dispatch their fish quickly and humanely using the ikijime method of brain destruction, a method scientifically proven to minimise stress for the fish while also maximising its eating qualities.

The 2.0 version of this app provides fast and unrestricted access to the database from www.ikijime.com, with cool photos and x-rays of a wide range of fish popularly targeted by anglers in Australia (100 species, 38 families), New Zealand (27 species, 16 families), North America (53 species, 25 families), South America (40 species, 23 families), Europe (31 species, 19 families), Asia (83 species, 32 families) and Africa (65 species, 28 families) together with helpful information on their brain location and other interesting fishy facts. Governments or other institutions wanting to increase the number of species in the database for their region, should please contact us on info@ikijime.com.

If you're fishing in remote locations, unlike the other Ikijime Tool apps, this "IkiJime Tool Extreme" version of the app carries its own database so will work in regions where there is no phone or internet coverage. After all, the best fishing spots tend to be in the most remote areas !

The "About IkiJime" button contains "How To" tips on the iki jime process. Once you know how to humanely kill your catch using the ikijime method, find your fish by using the "Search Fish" page. Select the region you are in, then the state or province, select the water type you are fishing in (freshwater, estuary or offshore), then select the relevant fish group and fish name from the dropdown list and hit "Go Fish" to access the database.

Another way to search is to use the Advanced (taxonomic) search option, which is useful if you know the taxonomic group or scientific names of the fish you are catching. Once you have selected your fish from the database by hitting "Go Fish", the fishes data page will appear with many fishy facts including alternative names, description, distribution, common and maximum sizes and more. You can then hit the x-ray button on the top right to use the very cool slide tool that shows the brain location of your fish superimposed as a white spot over easily recognised external landmarks.

Stick your brain spike into the spot, the fish is instantly and humanely killed, and you have dinner ! Other useful features include a "Take Pics" function that allows you to take pictures of your catch to send to your friends for identification or bragging rights, and the "Brochures" page, where you can download PDF brochures to print out, laminate and take fishing with you.

Good fishing and keep up to date with developments and future versions of these exciting apps at www.ikijime.com.

Needs an A-Z Index

Great concept of humane fish dispatch which I have now fully adopted.
The app would be much easier to use if there was an easy way to look up the fish if you already have an idea of what it is. Like an A-Z index. Otherwise great app thanks.

Simple, clear and concise

Works very well and I have noticed the massive improvement in flesh quality. This app has made it very easy to identify the brain and seeing the fish go completely limp from following the information on the app has made a big improvement in the treatment of fish in my local circle. Once I explain the message this app has taught me to my friends, they have all taken on board the humane killing of fish.

Sadly does not provide what is says

Firstly, I purchased the App to aid me in identifying the location of the fish brain. The X-ray button is not there and there is no tool to ID the brain location. Secondly, I am unable to contact the developer in any way, either via their www site or through the app itself, to try and sort my problem out. My preference to leaving a poor rating would have been to sort this out. As it stands, I am unable to recommend this App and feel frustrated at my loss of money!
