Preserving maritime ecosystems is a major concern for governments and administrations.
Additionally, improving fishing industry processes, as well as that of fish markets, to have a
more precise evaluation of the captures, will lead to a better control on the fish stocks. Many
automated fish species classification and size estimation proposals have appeared in recent
years, however, they require data to train and evaluate their performance. Furthermore, this
data needs to be organized and labelled. This paper presents a dataset of images of fish …

Methods Data acquisition was performed on a mobile phone without modifications,
specifically an iPhone 8 model, from Apple Inc. The requirement was that the image had to
be captured horizontally, with the phone as parallel to the tray as possible (ie shot
perpendicular to the fish tray), and with a fully visible tray. Furthermore, another requirement
was to aim for a minimum of 1,200 images as the target to have enough data for any
subsequent model training. A time frame of 6 months was considered, to account for species …
