A Fishackathon is a computer coding and other technology intensive event, or hackathon that takes place over a weekend. At the hackathon, developers, designers, project managers, and subject matter experts come together to create applications, systems, and tools for sustainable fishery issues. The participants will create applications and tools for a sustainable fishery issue that is internationally focused. Selected problem statements will be provided to coders and coders will will decide which one to address with their chosen teams. The 3rd annual Fishackathon will take place on Earth Day weekend, from April 22-24th, with a Friday evening event launch event followed by a 24-48 hour hackathon ending on Sunday. Results of the Fishackathon will be announced the following week. A panel of fishery experts and computer programmers will use standard criteria to judge the impact, innovation, and interface of the applications created at each Fishackathon event. Any and all works created during the Fishackathon are developed under the Creative Commons Attribution-ShareAlike 4.0 International License legalcode. The organizations and individuals who submitted problem statements will continue to work with the Fishackathon teams who worked on their respective problem statements to fully develop the ideas and ideally see them through to implementation.
