MATT MATTISON:
New Data Entry Website for Sizing Abalone!

The Nature Conservancy (TNC) is working with a group of northern California Recreational abalone fishermen to demonstrate a collaborative approach to data collection, data assessment and fishery management.  As part of that collaboration TNC is developing an online data collection “tool” that uses photo-recognition technology to measure abalone sizes.  We would like the help of interested abalone divers to develop the tool.
The tool is simple and easy to use and involves taking two pictures, measuring the size of each abalone that you take and then uploading it the following site: https://tncfish.typeform.com/to/CzaLS3 The data can be uploaded with either a cell phone or computer.  This is not a contest or competition.  We want as many abalone

measurements, taken from as many areas as possible, regardless of size.
The first data that is collected will be used by TNC to develop the tool and make sure that the two photos can be used to get an accurate size of an abalone.  This is why we need both a measurement and the pictures.  Once the software is developed we might be able to eliminate the measurement or use it simply for verification.

 Ultimately, the idea is to be able to collect a wide cross-section of size data, which can be used by the Department of Fish and Wildlife (DFW) and scientists to help manage our abalone fishery.  From this data scientist hope to be able to determine if actual catch sizes are increasing, decreasing or staying the same for all of the areas listed on the “Abalone Report Cards”.  Using this data, together with the sizes of maturity, we will know if the fishing pressure in each of the areas is sustainable.  It will also help the DFW and scientist to make better management decisions with minimal fishing restrictions.
If you want to help please record your abalone at the website above.  The sooner we can get this data collection tool operational, the better chance we have of it being used in the new Fisheries Management Plan (FMP) which is currently being developed by the Department of Fish and Wildlife.
