PROJECT TITLE<br />

The Automation of<br />

Fish-Stock Assessment<br />

ORGANIZATION(S)<br />

Bermuda Institute of<br />

Ocean Sciences (BIOS)<br />

LOCATION(S)<br />

St.George's, Bermuda<br />

MENTOR(S)<br />

Tim Noyes, Research<br />

Specialist, BIOS<br />

I worked training computer models to<br />

automatically identify fish species in Baited<br />

Remote Underwater Video systems (BRUVs).<br />

Marine biodiversity is often estimated from<br />

underwater video footage, but the manual<br />

annotation of fish is significantly time<br />

consuming. Automating the annotation of<br />

BRUVs would drastically improve the efficiency<br />

of marine research. I manually annotated<br />

approximately 14,000 images from multiple<br />

BRUVs, targeting fish species that occurred the<br />

most frequently. The images were then fed into<br />

convolutional neural network (CNN) models,<br />

which are often used in machine learning for<br />

automatic image classification. CNNs have<br />

internal parameters that are adjusted based<br />

on information contained in the training set<br />

and these parameters are later used to identify<br />

objects in new images. During my internship, I<br />

gained practical coding experience and learned<br />

more about computer vision techniques, and I<br />

developed time-management skills by organizing<br />

a large-scale project. I also have a greater<br />

awareness of issues related to marine biodiversity<br />

and conversation.<br />
